CTET (Level-I) Official Paper-I (Held On: 21 Jan, 2024 Shift 2) (English-Hindi) (Previous Year Paper)

The school curriculum is a powerful tool that can be used to shape students' knowledge and values. It is important to ensure that the curriculum is inclusive and responsive to the needs of all students, including students from diverse cultural backgrounds.

Key Points

• Assertion (A) is true. School curriculum should give reasonable space and value to learners' cultural knowledges. This is because cultural knowledge is an important part of students' identities. It can help them to understand themselves and their place in the world. When students see their own culture reflected in the curriculum, it can help them to feel more connected to their learning.
• Reason (R) is also true. Supporting students to uphold their cultural identities facilitates learning. This is because when students feel supported and respected, they are more likely to be engaged in their learning. They are also more likely to be successful in school.

Therefore, both (A) and (R) are true and (R) is the correct explanation of (A).

Socio-constructivist views of learning emphasize the importance of social interaction and collaboration in learning. These views see learning as a process of constructing knowledge through active engagement with the environment and with others.

Key Points

Socio-constructivist views of learning emphasize that learners are not passive recipients of knowledge.

• Rather, they actively construct knowledge through their interactions with the environment and with others.
• This means that learners are not simply absorbing information from their teachers or from textbooks. Instead, they are actively making sense of the world around them and constructing their own understanding of it.

Hence, Socio-constructivist views of learning advocate that learners actively construct knowledge.

Learning is a complex process that is influenced by a variety of factors. These factors include the learner's prior knowledge, the learning environment, and the nature of the task.

Key Points

• Learning is facilitated by social action. This means that learning can be enhanced through collaboration and interaction with others.
• Learning depends on learner's previous knowledge. This means that learners build on their existing knowledge and experiences to learn new things.
• Learning implies reorganization of prior conceptual schemes. This means that learning involves the modification and reorganization of existing knowledge structures.

Hint

• Learning is not simply a product that can be acquired. It is an ongoing process that involves the acquisition of new knowledge and skills, as well as the reorganization of prior conceptual schemes.

Hence, Learning as a product rather than a process is not correct about learning.

The development of motor skills is a complex process that begins in infancy and continues throughout childhood. Motor skills can be divided into two main categories: gross motor skills and fine motor skills. Gross motor skills involve the use of large muscle groups, such as those in the arms, legs, and torso. Fine motor skills involve the use of small muscle groups, such as those in the hands and fingers.

Key Points

The proximodistal principle of development states that growth and skill acquisition proceed from the center of the body outward.

• This means that children first gain control over the muscles closest to the body's core, which are involved in gross motor skills, before they master the use of muscles further from the center, such as those required for fine motor skills.
• Gross motor skills encompass larger movements such as crawling, walking, or jumping, which involve the arms, legs, feet, or entire body.
• These skills are generally developed earlier as they require the use of large muscle groups that are controlled by the more proximal parts of the body.
• Fine motor skills, on the other hand, involve more refined movements using smaller muscle groups, particularly those in the hands and fingers, such as grasping, holding, or manipulating objects.
• The development of fine motor skills follows gross motor skills because it depends on the more distal muscle groups, which are controlled later in the proximodistal progression.

Hence, the fact that children achieve gross motor skills before fine motor skills indicates that development is proximodistal.

Development is a complex process that encompasses physical, cognitive, and social changes. Cognitive development refers to the changes in thinking, learning, and problem-solving abilities that occur throughout childhood and adolescence.

Key Points

Reasoning, thinking, and problem-solving are all aspects of cognitive development.

• Cognitive development refers to the changes in thinking, learning, and problem-solving abilities that occur throughout childhood and adolescence.
• These changes are influenced by a variety of factors, including genetics, environment, and experience.

Therefore, Reasoning, thinking, and problem-solving are all explained in the aspect of development known as cognitive development.

Jean Piaget's theory of cognitive development outlines how children's way of thinking changes as they grow. This theory is divided into four stages, each characterized by different thought processes and capabilities.

Key Points

The instance described, where Aru claims the rope deliberately got her out while playing a jumping game, exemplifies a form of thinking characteristic of Piaget's Pre-operational stage. This stage typically spans the ages of 2 to 7 years.

• During the Pre-operational stage, children engage in symbolic play and develop their language skills. However, their thinking is still not very logical and they tend to be egocentric, meaning they find it difficult to see situations from perspectives other than their own.
• Another key feature of this stage is that children in the Pre-operational stage often ascribe life and intention to inanimate objects, a concept known as animism.
• In the scenario with Aru, her reasoning that the rope deliberately caused her to get out reflects this animistic thinking and shows a lack of logical thought processes that would allow her to understand the true nature of accidents or the inanimate nature of objects. Thus, Aru's reasoning aligns with the characteristics of the Pre-operational stage.

In conclusion, when Aru claims that the rope deliberately got her out, she is displaying cognitive attributes associated with Piaget's Pre-operational stage.

The proximodistal principle is a concept in developmental psychology that describes the pattern of growth and development in infants and young children. According to this principle, development proceeds from the center or core of the body (proximal) outward towards the extremities (distal). This principle helps understand the sequential and directional nature of physical growth during early stages of life.

Key Points The proximodistal principle implies that the development of body parts closer to the core or trunk occurs before those at the extremities. In infancy, this is observed in the growth pattern where the limbs (such as the upper arms and thighs) tend to grow faster than the hands and feet.

• This sequence of development is particularly noticeable during the early stages of life when infants go through significant physical changes. Initially, motor control and strength develop in the central parts of the body, enabling activities like rolling over and sitting up. As infants progress, they gain control over the muscles in their arms and legs, leading to crawling and eventually walking.

Hence, we can conclude that the proximodistal principle states that in infancy the limbs continue to grow faster than the hands and feet.

The concepts presented in both the assertion (A) and the reason (R) are rooted in constructivist theories of learning, which emphasize that learners actively construct their own understanding and knowledge of the world, through experiencing things and reflecting on those experiences. 

Key Points

• Assertion (A): "Learners construct their own knowledge based on what they already know," is a foundational principle of constructivism. It emphasizes that students are not passive recipients of information. Instead, they use existing knowledge as a foundation for new learning, constructing new understandings based on how they interpret new experiences or information.
• Reason (R): "Finding patterns and making linkages with previous knowledge helps learners to process information meaningfully," explains one of the mechanisms through which learners construct knowledge. By finding patterns and connecting new information with what they already know, learners are able to process and make sense of new information more meaningfully. This is a key aspect of how knowledge construction occurs according to constructivist principles.

Hence, both (A) and (R) are true and (R) is the correct explanation of (A).

Development is a continuous process with a predictable sequence, yet having a unique course for every child. 

Key Points

• Assertion (A) Childhood is experienced differently by children across cultures. This statement is true.
• Childhood experiences, practices, societal expectations, and roles vary significantly across different cultural settings.
• These differences can encompass a wide range of aspects, from parenting styles, education, play, rites of passage, and responsibilities, to the very concept of childhood itself.
• Reason (R) Children's development is universal. This statement, in the broad sense that it might negate the cultural differences impacting development, is false.
• While there are certain biological and psychological developmental stages that all humans go through, the ways these stages are experienced, supported, and interpreted can vary widely across cultures.
• This includes variations in the timing of developmental milestones, the value placed on different developmental outcomes, and the methods used by communities to support children's growth.
• Thus, while certain aspects of development might follow a biological pattern, the experience and support of these developmental stages are deeply influenced by cultural context.

Hence, we can conclude that (A) is true but (R) is false.

Lawrence Kohlberg's theory of moral development proposes that individuals progress through stages in their understanding of morality, moving from a simple understanding of consequences to more complex considerations involving principles and universal ethics.

Key Points

• (A) states that, in Kohlberg's theory, children move from understanding the consequences of acts to determining whether they are good or bad, ultimately realizing that rules and laws are flexible and can be changed. This aligns with Kohlberg's stages, particularly the later stages where individuals move beyond a focus on mere consequences and start considering broader principles and societal values. Therefore, (A) is true.
• (R) posits that Kohlberg argues for progressive stages in moral development. This is indeed accurate. Kohlberg identified six stages grouped into three levels – pre-conventional, conventional, and post-conventional. Each stage represents a more complex and principled understanding of morality. Thus, (R) is true.

In conclusion, both (A) and (R) are true, and (R) provides an accurate explanation of (A).

Inclusive education is a philosophy and approach that aims to provide equitable learning opportunities for all students, including those with diverse abilities, backgrounds, and learning styles. It emphasizes creating an environment where every student feels valued, respected, and included.

Key Points

• An inclusive classroom "accommodates differences in language styles and promotes collaboration.": This statement aligns with the principles of inclusive education, as it emphasizes the importance of recognizing and accommodating diverse language styles and fostering collaboration among students.
• Inclusive teaching means "teaching in ways that do not exclude.": This statement accurately reflects the essence of inclusive education. Inclusive teaching involves creating an environment where no student feels excluded based on their abilities, backgrounds, or learning styles.
• Inclusive teaching means "adopting pedagogies that support needs of all learners.": This statement aligns with the principles of inclusive education. Inclusive teaching involves using varied pedagogical approaches to address the diverse needs of all learners in the classroom.

Hint

• An inclusive classroom centres around "fixed curricula and standard assessment.": This statement is not consistent with the concept of inclusive education. Inclusive classrooms aim to adapt teaching methods and curricula to meet the diverse needs of students, moving away from a one-size-fits-all approach.

Hence, based on the analysis, the statement an inclusive classroom center around "fixed curricula and standard assessment"  is not correct regarding inclusive education.

Lev Vygotsky, a renowned developmental psychologist, made significant contributions to the field of educational psychology and child development. One of his key concepts is the idea that social interaction plays a crucial role in cognitive development. 

Key Points 

Inner speech

• According to Vygotsky, inner speech, or the process of internalizing language, is crucial for self-regulation.
• As children engage in social interactions and verbalize their thoughts, they gradually internalize this speech, which later becomes a tool for regulating their thinking and behavior.
• As children engage in social interactions and dialogue, children develop the ability to use inner speech as a cognitive tool, helping them regulate their thoughts, actions, and problem-solving skills independently.
• This concept underscores the importance of social interaction and language in shaping cognitive processes and self-regulation during development.

​Hence, we can conclude that Inner speech is important for self-regulation in children.

Additional Information

• Adaptation: While adaptation is important in various aspects of development, Vygotsky's emphasis on social interaction and the role of language suggests that it may not be the primary factor for self-regulation.
• Organization: Organization is an essential aspect of cognitive development, but Vygotsky's theory emphasizes the socio-cultural context and the role of language in shaping cognitive processes.
• Disequilibrium: Disequilibrium refers to a state of imbalance, and while Vygotsky acknowledged the importance of challenges in learning, it may not be directly associated with self-regulation in his theory.

Jean Piaget's theory of cognitive development outlines distinct stages through which individuals pass, each characterized by unique cognitive abilities and perspectives. The transition from pre-operational thinking to concrete operational thinking is a critical stage in this theory. 

 Key Points

Decentering: Decentering is a key ability associated with concrete operational thinking. It refers to the capacity to consider multiple aspects of a situation and to understand that others may have different perspectives.

• Decentering is the ability that distinguishes concrete operational thinking from pre-operational thinking in Jean Piaget's theory.
• As individuals progress through the concrete operational stage, they acquire the capacity to decenter, considering multiple perspectives and recognizing that others may have different views.
• This shift marks a significant cognitive development and is a defining feature of concrete operational thinking in Piaget's theory of cognitive development.

Hence, Decentering distinguishes concrete operational thinking from Pre-operational thinking​.

Critical evaluation is a fundamental skill in the realm of education, enabling students to not only comprehend information but also to scrutinize its validity, relevance, and applicability to real-world situations. Assessing a student's ability to evaluate information critically requires questions that push beyond mere recall or understanding, challenging them to engage thoughtfully with the material, analyze arguments, and form reasoned opinions based on evidence. Among the types of questions that could be utilized in assessments, some are specifically tailored to foster and evaluate these critical thinking skills.

Key Points

Questions that ask for the student's personal opinion: Questions that solicit the student's personal opinion, especially when they require justification or evidence to support that opinion, are effective in assessing critical evaluation skills.

• These types of questions compel students to not only articulate their own perspectives but to also engage in critical analysis by weighing the strengths and weaknesses of the arguments presented in the text.
• They must differentiate between facts, assumptions, and opinions, and use logical reasoning to support their stance.
• This process necessitates a deep engagement with the material, encouraging students to reflect on their values and beliefs about the information presented, thereby showcasing their ability to critically evaluate information.

Hence, Among the options provided, questions that encourage students to express and justify their personal opinions are particularly effective in this regard.

The relationship between cognition (thinking, processing information) and emotion (feeling, affective responses) is a complex and dynamic interaction that has been studied in psychology. Understanding how these two systems interact can shed light on various aspects of human behavior and experience.

Key Points

Emotion and cognition are interdependent on each other.

• This statement best captures the dynamic and bidirectional relationship between cognition and emotion.
• Research indicates that cognitive processes can influence emotional experiences, and, conversely, emotions can shape cognitive processing.
• The interdependence reflects the intricate ways in which these systems interact.

Therefore, the most accurate and comprehensive description of the relationship between cognition and emotion is  "Emotion and cognition are interdependent on each other."

Language development in primary classes is a critical aspect of a child's overall education. Effective language instruction not only contributes to linguistic proficiency but also enhances cognitive skills and understanding. The methods and approaches used by teachers can significantly impact language development.

Key Points

When teachers use concrete examples to refer to abstract concepts.

• This approach aligns with effective language instruction.
• Using concrete examples helps make abstract concepts more accessible to young learners.
• It provides a solid foundation for language development by connecting language to tangible experiences and fostering a deeper understanding.

Therefore, the most effective approach for facilitating language development in primary classes is "When teachers use concrete examples to refer to abstract concepts."

Attribution theory, developed by Bernard Weiner, explores how individuals attribute success and failure to various factors, impacting their motivation and subsequent behavior. Different attribution styles can influence one's approach to challenges and achievements.

Key Points

Making internal attributions for both successes and failures suggests that an individual believes their efforts and abilities are the primary factors in their outcomes.

• When individuals attribute their successes to internal factors, such as their own efforts or abilities, it reinforces their sense of competence and control.
• This positive reinforcement encourages them to continue putting forth effort, believing that they have the power to influence future outcomes.
• Similarly, when failures are also attributed to internal factors, although potentially disappointing, it maintains the perception that the individual has control over the situation.
• This perspective can lead to a more constructive response, where instead of feeling helpless or resigned, the individual is motivated to exert more effort, acquire new skills, or change strategies to achieve better results in the future.
• Internal attributions for failure promote a growth mindset, where challenges are seen as opportunities for learning and improvement.

In summary, the attribution of both successes and failures to internal factors is more likely to result in persistent effort and improved performance.

The inclusion of students belonging to disadvantaged groups is a critical aspect of creating an equitable and supportive educational environment. Inclusive education aims to provide equal opportunities for all students, irrespective of their background or social status.

Key Points

Awareness and sensitization towards diverse traditions.

• This option aligns with the principles of inclusive education.
• Fostering awareness and sensitization towards diverse traditions promotes a culture of respect, understanding, and appreciation for differences, contributing to an inclusive and supportive classroom environment.

Hence, "Awareness and sensitization towards diverse traditions" is consistent with the principles of inclusive education.

Issues related to gender in society often manifest in various ways, including attitudes, beliefs, and expectations. Tanuj's statement about his sister participating in jump rope because she is a girl and cannot throw javelin suggests a perspective that may be influenced by gender-related assumptions.

Key Points

Gender stereotyping

• Gender stereotyping involves making assumptions about individuals based on their gender, often reinforcing traditional roles or expectations.
• Tanuj's statement aligns with gender stereotyping, as he assumes that girls cannot participate in activities like javelin throwing.
• By associating specific activities with gender and making assumptions about his sister's abilities based on her gender, Tanuj reinforces traditional gender roles and expectations.
• Promoting awareness and challenging such stereotypes is essential for fostering an environment of gender equality, where individuals are free to pursue activities based on their interests and abilities rather than being limited by societal expectations associated with their gender.

Therefore, the concept depicted in Tanuj's statement is gender stereotyping.

Dyslexia is a neurodevelopmental disorder that primarily affects reading and related language-based processing skills. It is essential to recognize the key characteristics associated with dyslexia to provide appropriate support and interventions for individuals with this condition.

Key Points 

Difficulty in phonological processing

• Phonological processing difficulties are a typical characteristic of dyslexia.
• Phonological processing involves recognizing and manipulating the sounds of spoken language, and individuals with dyslexia often struggle with phonemic awareness, phonological memory, and decoding skills, which are crucial for reading.
• Individuals with dyslexia often face challenges in accurately and efficiently processing the sounds of spoken language, which can impact their ability to decode words and develop proficient reading skills.
• Recognizing this characteristic is essential for early identification and appropriate intervention strategies to support individuals with dyslexia in their academic and personal development.

Therefore, the typical characteristic of dyslexia among the provided options is "Difficulty in phonological processing."

Problem-solving is a cognitive process that involves finding solutions to complex or challenging situations. Different cognitive processes and thinking styles can influence problem-solving abilities. 

Key Points

Divergent thinking

• Divergent thinking is a cognitive process characterized by the generation of a variety of possible solutions to a problem.
• It involves exploring multiple perspectives, considering different options, and fostering creativity, making it a key factor in promoting effective problem-solving.

Hence, the factor that fosters problem-solving among the provided options is "Divergent thinking."

Divergent thinking and convergent thinking are two cognitive processes that play distinct roles in problem-solving and creative thinking. 

Key Points

• Divergent thinking involves the generation of multiple ideas or solutions, while convergent thinking focuses on finding a single, correct answer.
• Convergent thinking is a cognitive process whereby an individual focuses on finding a single, well-defined answer to a problem.
• This type of thinking is characterized by the ability to apply logical and analytical reasoning to arrive at a solution.
• Convergent thinking is often associated with tasks that involve decision-making, problem-solving, and the application of established rules and procedures.
• It contrasts with divergent thinking, where the aim is to generate multiple, varied ideas or solutions to a given problem, often requiring creativity and outside-the-box thinking.

Hence, we can conclude that divergent thinking encourages multiple answers while convergent thinking is fixed on one correct solution.

Formative assessment is an ongoing process that involves gathering information about students' learning progress and understanding throughout the instructional period.

Key Points

• Formative assessment is designed to provide feedback that can be used to modify and improve teaching and learning activities.
• An assessment task that helps compare students as per a standard set of criteria.
• This description aligns more with summative assessment, which typically involves evaluating students' performance against predetermined standards at the end of an instructional period. It is not a characteristic of formative assessment.

Hence, the option that would not be characterized as formative assessment is "An assessment task that helps compare students as per a standard set of criteria."

Feedback is a crucial component of the teaching and learning process, providing information to students about their performance and guiding them toward improvement. 

Key Points

• Effective feedback goes beyond merely stating the correct answer; it should be constructive, timely, and specific.
• Timeliness and specificity are key characteristics of effective feedback.
• Timely feedback allows students to connect it with their recent efforts, and specificity helps them understand precisely what they did well and areas for improvement.

Therefore, the characteristic of effective feedback in the classroom is "It is timely and specific."

Howard Gardner's theory of multiple intelligences proposes that intelligence is not a single, fixed entity, but rather a combination of various distinct abilities or intelligences. 

Key Points

Musical: performance or composition skills

• Musical intelligence involves sensitivity to rhythm, pitch, melody, and the ability to perform or compose music.
• Individuals with musical intelligence often excel in activities related to music.

 Additional Information

• Spatial: skill of appreciating the natural world: This match is not accurate. Spatial intelligence involves the ability to perceive and understand visual information, such as spatial relationships, and is not specifically tied to appreciating the natural world.
• Intrapersonal: skill in understanding and relating to others: This match is not accurate. Intrapersonal intelligence refers to self-awareness and understanding one's own emotions, motivations, and goals. It is more focused on internal self-awareness than understanding and relating to others.
• Logical-Mathematical: the skill of dance or athletic abilities: This match is not accurate. Logical-mathematical intelligence is associated with analytical thinking, problem-solving, and mathematical reasoning. It is not directly linked to dance or athletic abilities.

Therefore, the correct match of intelligence and associated characteristics according to Howard Gardner's theory of multiple intelligences is "Musical: performance or composition skills."

Intrinsic motivation refers to the drive that comes from within an individual, characterized by a genuine interest in and enjoyment of a task or activity. It is rooted in personal satisfaction, curiosity, or the inherent pleasure derived from engaging in an activity. 

Key Points 

Intrinsic Motivation that comes from personal enjoyment of the task

• This description accurately characterizes intrinsic motivation. When individuals engage in an activity because they find it inherently enjoyable, interesting, or satisfying, their motivation is intrinsic.
• Intrinsic motivation is driven by the inherent pleasure, interest, or satisfaction derived from engaging in an activity, and it is not dependent on external rewards, competition, or fear of punishment. Understanding intrinsic motivation is crucial for fostering a deep and enduring commitment to tasks and activities.

Hence, the correct description of intrinsic motivation is "Motivation that comes from personal enjoyment of the task."

Progressive education emphasizes the importance of student-centered learning, individualized instruction, and a focus on real-world, authentic experiences. 

Key Points

• Progressive educators advocate for active student engagement, critical thinking, and the development of social and emotional skills.
• Progressive educators emphasize the value of authentic, real-world tasks that connect learning to practical experiences.
• This approach promotes deeper understanding and meaningful application of knowledge.
• This approach fosters a student-centered and inquiry-based learning environment, aligning with the core principles of progressive education.

Hence, the key principle of progressive education among the provided options is that "Learning should be based on authentic tasks."

Understanding the distinctions between impairment and disability is crucial in discussions related to health, wellness, and accessibility. These terms are often used in the context of individuals with varying abilities, and they have specific meanings within the framework of disability studies.

Key Points 

​Impairment is a biological condition, while disability is a functional condition.

• This represents the distinction between impairment and disability. Impairment is a biological or physical condition, often related to a deviation from normal bodily structure or function.
• Disability, on the other hand, is a functional limitation or restriction in the ability to perform certain activities due to the interaction between an impairment and the environment.

Hence, Impairment is a biological condition, while disability is a functional condition.

Scaffolding is an instructional strategy that involves providing support to learners as they develop new skills or understand complex concepts. It aims to assist learners in achieving their learning goals by offering guidance and assistance. 

Key PointsScaffolding can take various forms, and it often involves tools and techniques that help learners bridge the gap between what they know and what they need to learn.

Examples of scaffolding

• (a) Think-aloud: Think-aloud is a form of scaffolding where instructors verbalize their thought processes while solving a problem or completing a task. It provides a model for learners to understand the cognitive steps involved.
• (b) Prompts and cues: Prompts and cues are forms of support that guide learners as they engage in a learning activity. They help direct attention, provide hints, and encourage thinking without giving away the solution outright.
• (c) Questions: Asking questions is a common scaffolding technique. Well-structured questions can prompt critical thinking, guide the learner's thought process, and encourage deeper understanding.
• (d) Half-solved example: Providing a partially solved example is a form of scaffolding where learners are given a model with part of the solution already completed. This allows them to focus on specific steps or concepts while still providing guidance.

Hence, the correct examples of scaffolding among the provided options are (a), (b), (c), and (d).

Lawrence Kohlberg's theory of moral development outlines stages through which individuals progress in their understanding of moral issues and ethical reasoning. 

Key Points

• Kohlberg identified three levels of moral development, each consisting of two stages. The levels are pre-conventional, conventional, and post-conventional.
• Level 1 is the Pre-conventional Level, which is typical of children and is characterized by reasoning that is based on external consequences and individual needs, rather than societal conventions or laws.
• This level is divided into two stages:
• Stage 1: Obedience and Punishment Orientation - At this stage, the focus is on direct consequences to the self. Children see rules as fixed and absolute. Obeying the rules is important because it avoids punishment.
• Stage 2: Individualism, Instrumental Purpose, and Exchange - In Stage 2, the reasoning becomes slightly more advanced. Children recognize that there is not just one right view that is handed down by the authorities.
• Different individuals have different viewpoints. However, something is right if it serves the individual's needs or interests.
• This stage is characterized by a perspective that right behavior means acting in one's own best interest and that fairness is a reciprocal process, "You scratch my back, and I'll scratch yours."

Hence, we can conclude that at the second stage in the first level, children are self-centered and see their benefit in doing something.

Explanation:

1 is not a prime number because it can not be divided by any other integer except for 1 and itself. The only factor of 1 is 1.

1 is also not a composite number because it can not be divided by any other integer except for 1 and itself.

In conclusion, the number 1 is neither prime nor composite.

∴ 1 is neither a prime nor a composite number.

Given:

\(2\frac{2}{3}\) right angles.

Concept used:

1 right angle = 90° 

Calculation:                     

​\(2\frac{2}{3}\) right angles = \(\frac{8}{3}\) x 90​

⇒ ​\(\frac{8}{3}\) x 90​​​

⇒ 240° 

∴ The right answer is 240°.

Concept:

A regular polygon is a polygon that has all its sides of equal length and all its angles of equal measure.

Pentagon:

A pentagon can be regular or irregular. A regular pentagon does have all five sides equal in length and all five angles equal in measure (each angle being 108 degrees). An irregular pentagon will have sides and angles that are not all the same size. So, while a pentagon can be a regular polygon, it doesn't have to be.

Circle: A circle is not a polygon. It is a curved shape with no straight sides, and it does not have angles.

Isosceles Triangle: An isosceles triangle is not always a regular polygon. While it can have two equal sides, its angles may vary, and it may not have all sides and angles equal.

Square: A square is a regular polygon. It has four sides of equal length and four angles of equal measure.

∴ The correct option is option 4: square.

Given :

Total parcel weight = 350 gm

Parcel weighing charge -

50 grams or less = Rs. 15.00

For every additional 50 grams = Rs. 7.00

Calculations:

Charges for the first 50 gm of parcel = Rs. 15

⇒ Remaining weight = 350 - 50 = 300 gm

Since, Charges for every additional 50 grams = Rs. 7

So, Charges for the additional 300 gm =

⇒ 7/50 × 300 

⇒ Rs. 42

So, total charges for sending the parcel

⇒15 + 42 = Rs. 57

∴ The correct answer is Rs. 57.

The multiplicity of approaches in teaching mathematics is an important aspect of promoting deeper understanding and flexibility in problem-solving. 

Key Points

• Offering multiple approaches in math encourages critical thinking.
• It accommodates different learning styles and preferences.
• Students become more flexible and resilient problem solvers.
• It deepens conceptual understanding of mathematical concepts.
• Multiplicity of approaches enriches students' learning experiences.

Hence, the correct answer is It hampers the learning of child as it leads to confusion is not true about the 'multiplicity of approaches' in teaching mathematics

Key Points

• Visualization: Visualization is an essential process in a primary mathematics classroom as it helps students develop a concrete understanding of mathematical concepts by picturing them in their minds.
• Making connections and representations: Making connections and representations supports a deeper understanding of mathematical ideas, fostering critical thinking and problem-solving skills.
• Use of patterns: Recognizing and understanding patterns is a fundamental mathematical skill that promotes logical thinking and helps in making connections between different mathematical concepts.

Hint

• Memorizing formulae: While memorization is a part of learning, the emphasis on memorizing formulae without understanding can hinder conceptual learning, which goes against the principles of the National Curriculum Framework.

The correct answer is Memorising formulae

Cognitive conflict, in the context of teaching mathematics, refers to the deliberate introduction of situations or problems that challenge students' existing understanding, creating a mental struggle or conflict.

Key Points

• By exposing children to such challenges in a thoughtful manner, teachers provide opportunities for them to engage actively with complex problems.
• This engagement encourages students to delve into difficult concepts, explore various strategies and approaches, and ultimately refine their comprehension through active participation.
• Encountering cognitive conflict fosters critical thinking skills among students as they are prompted to question assumptions, reconsider their initial understandings, and explore alternative perspectives.

The correct answer is Thoughtful efforts of a teacher to expose children to cognitive conflict can enhance their mathematical understanding.

Teaching-learning resources in a mathematics class encompass a wide range of tools and materials designed to support and enhance the teaching and learning of mathematical concepts.

Key Points

• "Mathematics lab is essential as it provides opportunities for hands-on activities for students" emphasizes the importance of experiential learning in mathematics education.
• Mathematics labs offer students a hands-on and experiential approach to learning mathematical concepts.
• This helps students develop a deeper and more intuitive understanding of mathematical concepts by connecting theoretical knowledge with real-world applications.
• Mathematics labs provide opportunities for inquiry-based learning, where students are encouraged to ask questions, explore hypotheses, and seek solutions through investigation and experimentation.

Hence, we can conclude that the statement " Mathematics lab is essential as it provides opportunities for hands-on activities for students" is most appropriate.

Given:

Die threw 10 times result as 5, 3, 6, 6, 1, 4, 5, 3, 3, 2

Calculation:

Yamina threw a die 10 times following are result 

⇒ 1→ 1 times

⇒ 2→ 1 times

⇒ 3→ 3 times

⇒ 4→ 1 times

⇒ 5→ 2 times

⇒ 6→2 times

∴ Yamina  got the maximum number of times 3.

• Word problems refer to exercises where the child formalizes the situation into a form where a specific mathematical technique can be applied: True. Word problems involve translating real-world situations into mathematical expressions or equations, requiring the application of specific mathematical techniques.

Key Points

• Word problems are important in secondary classes only: Not true. Word problems are relevant and beneficial across various grade levels, including primary and secondary classes, as they provide real-world contexts for applying mathematical concepts.
• Word problems focus more on procedural knowledge in mathematics: Not entirely true. While procedural knowledge is involved, word problems often require students to understand the situation, identify relevant information, and choose appropriate mathematical strategies.
• Word problems are not examples of mathematical modeling: Not true. Word problems can be considered examples of mathematical modeling as they involve representing real-world situations mathematically to solve problems.

The correct answer is Word problems refer to exercises where the child formalizes the situation into a form where a specific mathematical technique can be applied.

Calculation:

Let the required number which is subtracted be x.

According to the question,

9909 + 9099 + 9009 - x = 25454

⇒ 28017 - x = 25454

⇒ x = 28017 - 25454

⇒ x = 2563

∴ 2563 should be subtracted from the sum.

Correct Answer is 2563.

Explanation:

We know that, 1 meter = 10 deci meter = 100 cm = 1000 mm

So, 1000 mm = 100 cm

⇒ 1 mm = 100/1000 = 0.1 cm

∴ The correct answer is option 4

Calculations:

To find out the next step on which they will be jumping together, we find the LCM.

⇒Both 3 and 7 are Co-prime numbers, therefore LCM will be equal to their product.

⇒3 x 7 = 21

⇒Hence they will be jumping together on the 21^st step

or will they jump together on a multiple of 21

∴ Out of the given options, 378 is a multiple of 21, both will jump together to the 378^th step.

Understanding the relationships among ones, tens, and hundreds is critical for grasping more complex mathematical concepts, including addition, subtraction, multiplication, and division involving larger numbers, as it lays the foundation for numerical literacy and place value comprehension.

Key Points

• Abacus: An abacus is a suitable model for developing a conceptual understanding of ones, tens, and hundreds. It provides a visual and tactile representation of place value, allowing students to manipulate beads to understand the relationships between different place values.
• Dienes blocks: Dienes blocks, or base-10 blocks, are excellent for representing ones, tens, and hundreds. They offer a hands-on approach, allowing students to build and deconstruct numbers to grasp the concept of place value.
• Place value chart: A place value chart is specifically designed for understanding the relationships of ones, tens, and hundreds. It provides a visual representation where students can see the position of digits and their corresponding place values.
• Money: While money involves numerical values, it may not be the most appropriate model for developing the conceptual understanding of place value. Money has its own set of symbolic representations, and its primary focus is on currency and transactions rather than on the relationships of ones, tens, and hundreds.

Hence, we can conclude that the Money model is least appropriate for developing the conceptual understanding regarding the relationships of ones, tens, and hundreds in early-grade learners.

Confusion Points

• The board has given the correct answer as Dienes block but according to us, the correct answer must be the Money model.

Given:

Total mass of salt = \(7\frac{1}{2}\) kg = 15/2 kg

Mass of one packet of salt = 1/12 kg

Calculation:

Total packet of salts = Total mass of salt/mass of one packet of salt

⇒ \(\frac{\frac{15}{2}}{\frac{1}{12}}\) = \(\frac{15\ \times\ 12}{2}\) = 90

∴ The correct answer is 90 packets.

Regrouping, also known as carrying or borrowing, is a fundamental concept in mathematics, particularly in operations like addition and multiplication involving multi-digit numbers.

Key Points

• Understanding Place Value: Regrouping helps in understanding that each digit's position in a number represents a different power of 10.
• Breaking Down Multiplication: It involves multiplying each digit in the multiplicand separately by each digit in the multiplier.
• Carrying Over: Regrouping includes carrying over the extra value to the next higher place value position when the product exceeds 9.
• Correct Arrangement of Partial Products: It ensures that the partial products are correctly arranged in their respective place value positions before adding them up.
• Example: In the multiplication of 26 by 5, regrouping ensures each digit is multiplied separately, and the results are correctly added to get the final product (130).

Hence, the correct answer is concept of regrouping.

Early number concept formation involves grasping fundamental ideas like one-to-one correspondence and hierarchical inclusion to understand numbers and their relationships.

Key Points

One-to-one correspondence:

• This concept involves matching one object with one numeral or counting word.
• It helps children understand that each object has a corresponding number and vice versa.
• Through activities like counting objects or pointing to each object while counting aloud, children learn the cardinal principle, which states that the last number counted represents the total quantity.

Hierarchical inclusion:

• Hierarchical inclusion refers to the understanding that numbers are composed of smaller numbers and are part of larger numbers.
• It involves grasping the hierarchical structure of the number system, where smaller units (e.g., ones) are grouped to form larger units (e.g., tens, hundreds).
• Children learn this concept by recognizing patterns in number sequences, understanding place value, and decomposing and composing numbers.

Hence, the correct answer is both (a) and (b).

• Formal examination to assess the knowledge gained by the students: NEP 2020 emphasizes a shift from rote learning to a more holistic and experiential approach. While assessments are essential, the focus is on a continuous and comprehensive evaluation rather than solely relying on formal examinations.

Key Points

Concept used:

Follow the BODMAS rule according to the table given below:

Calculation:

25.3 × 5 - 35 ÷ 5 - 3 × 18.5

⇒ 126.5 - 35 ÷ 5 - 55.5

⇒ 126.5 - 7 - 55.5

⇒ 126.5 - 62.5

⇒ 64.0

∴ The correct answer is 64.0.

Key Points

• Within the classroom, collecting statistics of students' height, favourite food, colour, cartoon, etc., and asking questions related to data: This option involves hands-on data collection within the familiar classroom environment, making it more suitable for the primary stage. It allows students to actively participate, collect data, and understand the concept of data handling in a relatable context.

Hint

• Showing the population census of a city for five years and asking students to compare population growth: This may be too complex for the primary stage, involving large datasets and comparisons that might be challenging for young students.
• Drawing a bar graph on the blackboard and asking students to read the data from it: While visual aids like bar graphs are valuable, drawing one on the blackboard might not involve active student participation in data collection.
• Asking the students to read timetables of bus and train timings: Reading timetables involves time-related data but may not cover a variety of data types or engage students in data collection.

The correct answer is  Within the classroom, collecting statistics of students' height, favourite food, colour, cartoon, etc., and asking questions related to data.

The National Education Policy (NEP) 2020 emphasizes a holistic approach to assessment, considering various domains of learners

Key Points. The three domains mentioned are:

• Cognitive Domain: This involves intellectual abilities, thinking processes, and understanding of concepts. It includes assessing learners' knowledge, comprehension, application, analysis, synthesis, and evaluation.
• Affective Domain: This domain focuses on the emotional and social aspects of learning. It includes assessing learners' attitudes, values, interests, and motivation. Affective assessment considers the development of social and emotional skills.
• Psychomotor Domain: This domain relates to physical skills and motor abilities. It involves assessing learners' physical coordination, dexterity, and proficiency in performing specific tasks.

The correct answer is  Cognitive, affective, and psychomotor domain

Given:

Brij had wire of length = 100 metres

Calculation:

We know if Brij choose to take the biggest area than chosen square area

∴  Parameter of square = 4a

⇒ 4a = 100

⇒ a = 25

⇒ Area of square = a² = 25 × 25

∵ Area of biggest land = 25m × 25m

• Additionally, demonstrating the process of regrouping in subtraction will help clarify the mathematical concept without causing confusion or anxiety for the student.
• This approach promotes effective communication, encourages student engagement, and supports the student's learning needs.

Therefore, the correct Teacher should change the word 'borrowing' to 'regrouping and then show the process of regrouping.is the most appropriate course of action for the teacher in this scenario.

The Correct Answer is: Both (A) and (R) are correct and (R) explains (A).

​ Key Points

• Statement (A): Silkworms can find their female counterparts from many kilometers away by her smell. This implies that silkworms use the sense of smell to locate and identify potential mates. In the context of insect communication, this is often achieved through the detection of pheromones.
• Statement (R): Some female insects release 'Pheromones' which can be recognized by their males by smell. This statement provides a general principle that is widely observed in the insect world. Pheromones are chemical substances released by an organism, in this case, female insects, to communicate with others of the same species. Male insects, in turn, can detect and respond to these pheromones using their sense of smell.

Thus, Both (A) and (R) are correct and (R) explains (A).

Child-centered strategies in teaching Environmental Studies (EVS) at the primary level focus on engaging students actively in the learning process and tailoring instruction to their interests and needs. 

Key Points 

• Discussion: Discussion encourages interaction, critical thinking, and expression of ideas. It involves students in the learning process and allows them to share their perspectives.
• Survey: Surveys involve students actively collecting data, forming questions, and exploring their environment. This approach fosters engagement and aligns with child-centered strategies.

Thus**, (a) and (d) is the correct answer.**

Hint

• Demonstration: Demonstration is a useful teaching method, it may not inherently be child-centered unless it actively involves students in hands-on activities or experiments related to the environmental studies.
• Lecture: Lecture-based teaching is traditionally more teacher-centered, as it involves the instructor imparting information to students. It might not align as closely with child-centered strategies.

Forming groups based on participation and cooperation is the most effective strategy for promoting peer learning.

Key Points Advantages of heterogeneous groups based on participation and cooperation:

• Diverse perspectives and strengths: By bringing together students with different levels of participation and cooperation, you create groups with a wider range of perspectives and strengths. This can lead to more stimulating discussions, richer learning experiences, and a better understanding of different approaches.
• Promotes collaboration and communication: Students with different levels of participation and cooperation can learn from each other. More participative students can help their peers develop their communication and collaboration skills, while those who are less confident can gain valuable insights from their more outgoing peers.
• Reduces dominance and encourages inclusivity: Grouping by participation and cooperation can help prevent dominant personalities from taking over group discussions. This fosters a more inclusive environment where everyone feels comfortable sharing their ideas and learning from each other.

Thus, option 1 is the most appropriate strategy.

Hint

• Grouping by gender or socio-economic background (option 2): This can lead to segregation and limit exposure to diverse viewpoints. It's important to create inclusive groups that celebrate differences and encourage students to learn from each other's unique experiences.
• Grouping by roll number (option 3): This is a random approach that doesn't consider individual strengths or preferences. It's unlikely to create groups that are conducive to effective peer learning.
• Grouping by exam scores (option 4): This can create homogeneous groups that lack diversity in learning styles and abilities. It can also be discouraging for students who score lower, as they may feel less able to contribute meaningfully to the group.

• Using a rating scale allows the teacher to evaluate multiple dimensions of student performance, such as knowledge acquisition, critical thinking, communication skills, and collaboration.
• Portfolio :
• ​Portfolios serve as a tangible record of students' work samples and achievements over time.
• In the context of EVS, portfolios can include written assignments, drawings, photographs, research papers, fieldwork reports, and any other artefacts demonstrating students' engagement with environmental concepts and issues.
• Portfolios often include reflections or self-assessments where students can articulate their learning experiences, challenges, and goals. This encourages metacognition and helps students take ownership of their learning process.
• ​Teachers' observation :
• ​Teachers' observations provide qualitative insights into students' attitudes, interests, and participation in EVS.
• Observations allow teachers to understand how students interact with environmental concepts in real-time and various learning environments.
• Observations help teachers assess students' behaviour, collaboration skills, and level of engagement during class activities, discussions, or fieldwork.
• This holistic assessment goes beyond academic performance to include social and emotional aspects of learning.
• Half-Yearly and Annual Exams:
• Half-yearly and annual exams assess students' understanding and retention of EVS content over extended periods.
• These exams typically cover a wide range of topics taught throughout the semester or academic year, including concepts, theories, case studies, and real-world applications related to environmental studies.
• By testing students through formal examinations, teachers can gauge their mastery of core EVS principles, their ability to analyze environmental problems, and their capacity to articulate solutions.
• Exam results provide quantitative data that complement the qualitative insights gained from other assessment methods.

Therefore, The correct answer is All of the above.

Key Points

• Writing names of various animals around them is an appropriate task for primary students in EVS. It encourages observation and recognition of animals in their surroundings, connecting learning to their immediate environment.
• Observing activities of different animals is also suitable for primary students. It promotes direct observation skills and understanding of animal behavior, aligning with the experiential nature of EVS.
• Classifying animals into categories based on observations is a valuable task for primary students. It involves critical thinking and organizing information, fostering a deeper understanding of animal characteristics.

Thus, Only (d) is not appropriate for students of the primary level in the context of EVS.

Hint

• Defining the term 'Animal' might be more suitable for slightly older students as it involves abstract thinking and the ability to articulate a definition. Primary level students may find this task challenging as it requires a more advanced level of cognitive development.

The Correct Answer is: Both (A) and (B) are true

​ Key Points

• Statement (A): Xylem transports water and minerals from roots to the rest of the plant. This is correct. Xylem is a type of vascular tissue in plants responsible for the upward transport of water and minerals from the roots to the other parts of the plant.
• Statement (B): Phloem translocates food from leaves to various parts of the plant. This is also correct. Phloem is another type of vascular tissue responsible for the transport of organic nutrients, such as sugars produced in the leaves through photosynthesis, to various parts of the plant.

Therefore, both statements (A) and (B) are true.

• Travel: It can be incorporated to introduce students to the concept of transportation, the modes of travel, and the reasons people travel. This theme allows exploration of the immediate environment.
• Things we make and do: This theme encompasses a wide range of activities, creations, and objects that are part of daily life. It allows students to explore the process of making things, engaging in activities, and understanding the objects around them.

Thus, the combination of Shelter, Travel, and Things we make and do covers a diverse set of themes that align with the experiential and exploratory nature of primary level EVS.

Key Points

• A blood test for malaria typically involves checking for the presence of the malaria parasite (Plasmodium) or its byproducts in the patient's blood.
• This is done to identify the presence of the malarial infection.
• The test may involve examining blood smears under a microscope or using more advanced laboratory techniques to detect the parasites or their genetic material.

Thus, doctors prescribe blood test for patients to confirm malaria. Blood test is done to check for microbes in blood.

Additional Information

• Checking for eggs of female Anopheles mosquitoes in blood is not a standard diagnostic method for malaria. Malaria is caused by the Plasmodium parasites, not by mosquito eggs.
• Checking for hemoglobin in the blood is often done for other purposes, such as assessing the patient's overall health or investigating conditions like anemia, but it is not a specific test for malaria.
• Checking iron levels in the blood is typically done to assess iron metabolism and diagnose conditions like iron deficiency anemia but is not specific to malaria.

The statement that "Textbooks of EVS should reflect the recommendation of NCF 2005 of linking students' life at school to their life outside" implies textbooks support students to construct knowledge through all the given activities.

Key Points

• The National Curriculum Framework (NCF) 2005 emphasizes the integration of students' life experiences with their learning. This suggests that textbooks in Environmental Studies (EVS) should not just be a source of information but should actively support students in constructing knowledge by connecting what they learn in school with their real-life experiences outside the school.
• Constructivist learning approaches encourage students to actively build their understanding by connecting new information to their existing knowledge and experiences.
• This aligns with the idea that textbooks should support students in constructing knowledge through various activities that bridge the gap between their life at school and life outside .

Thus, option 1 is the correct answer.

Key Points

• King Ghadsi of Jaisalmer got it made 650 years ago with the help of the people. All around the lake there are ghats with steps leading to the water, decorated verandahs, large halls, rooms and much more.
• People came here to celebrate festivals and for programmes of music and dance.
• This lake was made for collection of rainwater as rainwater harvesting.
• It was made in such a way that when the lake was full, the extra water flowed into another lake at a lower level.
• When that too filled up, the extra water flowed into the next lake.
• This way all nine lakes filled up.
• Today, Ghadsisar is no more in use.

​Thus, option 2 is the correct answer.

A field trip is an educational excursion or journey outside of the classroom, typically to a place of educational interest, such as a museum, zoo, historical site, science center, botanical garden, or any location relevant to the subject being studied.

Key Points

Therefore, option 2) (b), (d), and (a) is the most appropriate choice for the reasons for including the chapter on Wahida Prism.

Key Points

• Asking students to find out food preferences of their family members: This strategy encourages students to actively inquire about their family members' food preferences.
• It involves them in conducting surveys, interviews, or discussions to gather information.
• This process not only engages students in inquiry but also connects the theme of 'Food' to their personal experiences, making it relevant and meaningful.

Thus, option 1 is the correct answer.

Hint 

• Showing pictures of various preserved food items used in different regions of India: While visual aids can be valuable, merely showing pictures might not actively engage students in inquiry unless accompanied by discussions or activities that encourage deeper exploration of the cultural and regional aspects of preserved foods.
• Asking students to collect pictures of various food items: Collecting pictures can be a part of an inquiry-based approach, but it needs additional elements to stimulate deeper inquiry, such as researching the origin, cultural contexts, or nutritional aspects of the food items.
• Demonstrating fireless cooking of sandwiches, shikanji (lemon water), etc.: While a demonstration is hands-on and practical, it may focus more on acquiring skills than actively inquiring into the broader theme of 'Food.' It involves learning through observation and practice rather than initiating inquiry into diverse aspects of food.

Key Points

• Statement (A): Bora is a common variety of rice used in Assam. This statement is true. Bora is indeed a variety of rice cultivated in Assam.
• Statement (B): Paddy grows well in clayey soil and requires a lot of water. This statement is also true. Paddy, which is the rice plant in its growing stage, thrives in clayey soil and requires abundant water for cultivation.

• Since the reason provided is incorrect, it does not explain the assertion properly.

Additional Information

• Boiling Point and Pressure: The boiling point of a liquid is the temperature at which its vapor pressure equals the external pressure. Lower external pressure at high altitudes means water boils at a lower temperature.
• High Altitude Cooking: Since water boils at a lower temperature, it cannot get as hot as it can at sea level, making cooking inefficient. Special cooking methods or extended cooking times are often necessary.
• Practical Implications: This is an important consideration for activities such as mountaineering or living in high-elevation areas where cooking can be challenging due to these changes in boiling point.

The behavior described, where the male bird constructs multiple nests and the female makes a choice about where to lay her eggs, is of the Weaver bird.

 Key Points

• Weaver birds are known for their intricate nest-building skills.
• Male weaver birds build multiple nests to attract a female. The female then inspects the nests and makes a decision on which one she finds most suitable for laying eggs. This behavior is a part of their mating ritual.
• Weaver bird nests are often elaborate and woven, constructed with a variety of materials such as grass, twigs, and leaves. The complexity and quality of the nest can influence the female's choice of a mate.
• The intricate nest-building behavior is a way for the male weaver bird to demonstrate its fitness as a mate and provider.

Thus, Weaver bird is the correct answer.

Key Points

• Assertion: The theme 'Family and Friends' is a major theme in EVS, and 'Plants and Animals' are presented as a subtheme of 'Family and Friends.: This assertion suggests that within the broader theme of 'Family and Friends' in Environmental Studies (EVS), the specific subtheme of 'Plants and Animals' is incorporated. The idea here is likely to emphasize the interconnectedness and relationships between humans and other living organisms.
• Reason: The interdependence of human beings and other forms of life is highlighted through themes. The reason supports the thematic approach in EVS. Highlighting the interdependence of human beings and other forms of life aligns with the holistic understanding of ecosystems and their components.

Therefore, option 3) Both the assertion and reason are correct and the Reason is the correct explanation of the Assertion is the correct answer.

Key Points 

• Questioning: Students will likely need to formulate clear and relevant questions to gather information about the number of family members and the amount of water used in each family. Questions might include inquiries about daily routines, water usage habits, and the number of people in the household.
• Inferring: After collecting survey data, students will need to make inferences based on the information gathered. For example, they may infer trends or patterns in water usage based on the size of the family, daily activities, or specific habits.
• Expression: Communication skills come into play when students share their findings with others. They might need to express their observations, draw conclusions, and present the data clearly and understandably. This can involve both written and verbal communication, fostering effective expression of ideas.

Thus, questioning, inferring, expression is the most appropriate set of skills and processes developed through the activity of conducting a survey on family members and water usage.

Haryana is surrounded by the states of Himachal Pradesh, Rajasthan, and Uttar Pradesh.

Key Points

• To the northwest, Himachal Pradesh forms a part of Haryana's border, while Rajasthan lies to the southwest. Uttar Pradesh shares its eastern boundary with Haryana.
• These neighboring states contribute to the diverse geographic and cultural landscape of Haryana, as it experiences influences from the Himalayan region, the Thar Desert, and the Gangetic plains.
• The proximity to these states also plays a role in the economic and cultural exchanges that shape Haryana's identity.

Thus, option 3 is the correct answer.

The Correct Answer is: (a) and (d)

Key Points

• Honey bees live in beehives. Every beehive has one queen Bee that lays eggs. This statement is true. Honey bees do live in beehives, and each hive has one queen bee whose primary role is to lay eggs.
• The worker bees fly around Litchi flowers in search of nectar for honey. This statement is true. Worker bees do fly around various flowers, including litchi flowers, to collect nectar, which they turn into honey for the hive.

​Thus, (a) and (d) is the correct answer.

Analytical questions require students to break down a problem or situation into parts and examine how these parts relate to one another

 Key Points

• In this case, students are prompted to analyze the reasons behind the comfort provided by woolen clothes during winter.
• The question goes beyond factual knowledge (knowing that we feel comfortable in woolen clothes) and encourages students to think critically about the underlying reasons or factors contributing to that comfort.
• Analytical questions often involve higher-order thinking skills as students need to analyze, evaluate, and synthesize information to provide a thoughtful response.

Hint

• Hypothetical question: This involves imagining an unreal or “what if” situation (e.g., What would happen if there were no winters?). The given question is based on real experience, so it is not hypothetical.
• Factual question: A factual question asks for a direct fact or definition (e.g., What is wool?). Here, students must explain why, not recall a fact.
• Convergent question: A convergent question usually leads to one short, fixed answer (often recall-based). Although the concept is known, the question expects reasoning and explanation, not a single-word response.

Therefore, the question about feeling comfortable in woolen clothes during winter is best classified as an analytical question.

Key Points

• Statement (A) is referring to the Indus Valley Civilization, one of the world's oldest urban cultures. Around 4700 years ago, during the Bronze Age, cities like Mohenjo-Daro and Harappa thrived along the banks of the Indus River and its tributaries in what is now modern-day Pakistan and northwest India.
• Statement (B) is false. Cities along the banks of the Ganga and its tributaries have a much longer history, dating back thousands of years. The statement mentions 1500 years ago, but civilizations and urban settlements along the Ganga have a history that goes back much further.

Thus, (A) is true but (B) is false.

The correct answer is '(a) and (c) are right but (b) is wrong.'

Key Points

• Mrs. Higgins entered the drug store not properly dressed, which is evident from the description that her clothes seemed to have been "thrown on her." This confirms the accuracy of statement (a).
• The text does not provide any indication that Mrs. Higgins looked guilty or like the mother of a guilty person upon her entrance. Instead, it emphasizes her calmness and dignity, which contradicts (b).
• Mr. Carr's reaction to Mrs. Higgins' demeanor, which he had not anticipated, confirms (c). He was taken aback by her composed response and asked if her son was in trouble, indicating that he did not expect her to be calm and dignified.
• There's no support in the text to confirm the presumption in statement (b) that she looked like the mother of a guilty person; her composed demeanor was unexpected and contrasted with this assumption.

Therefore, the correct answer is 'Option 1'.

The correct answer is 'Conjunction'

Key Points

• In the sentence, "that" is used to introduce a clause explaining the reason or the result of something. It connects two parts of a sentence.
• Conjunctions are words used to connect clauses or sentences or to coordinate words in the same clause.
• "That" is one of the most common conjunctions used in English.
• It serves to introduce the explanatory clause "her clothes seemed to have been thrown on her."

Therefore, the correct answer is 'Option 2'.

The correct answer is 'At Mr. Carr's accusation, Alfred's mother felt intimidated.'

Key Points

• The text does not suggest that Mrs. Higgins felt intimidated by Mr. Carr's accusation. Instead, it portrays her as composed and dignified, indicating she did not exhibit intimidation.
• Mrs. Higgins' response to Mr. Carr is characterized by understanding and gentleness, further suggesting that she was not intimidated but instead sought to mediate the situation calmly.
• Alfred was indeed portrayed as having stolen items, making the statement that he was a petty thief accurate based on Mr. Carr's account.
• The specific items Alfred stole from the store, including cream, compact, and lipstick, are mentioned in the narrative, confirming their accuracy.
• Mrs. Higgins' attempt to handle the situation by asking Mr. Carr to listen before taking action illustrates her effort to protect her son and not a reaction of feeling intimidated.

Therefore, the correct answer is 'Option 1'.

The correct answer is 'He felt that he would have to forgive Alfred.'

Key Points

• Mr. Carr's reaction upon meeting Mrs. Higgins is more aligned with being unsure of what to do or say rather than an immediate inclination to forgive Alfred. He acknowledges the possibility of getting a cop, which does not directly imply an intention to forgive.
• The text explicitly states Mr. Carr was a bit embarrassed and hardly knew what to say to Mrs. Higgins when she introduced herself, which does show his stupefaction but not a decision to forgive.
• The comparison between Mrs. Higgins' potential reaction at home and her actual behavior in the store illustrates her ability to maintain composure publicly, even though she might react differently in private. This supports the idea that she would be enraged at home and caring outside.
• There is no textual evidence to suggest that Mr. Carr felt compelled to forgive Alfred following the encounter with Mrs. Higgins. His consideration of police involvement indicates deliberation rather than an intent to forgive.

Therefore, the correct answer is 'Option 2'.

The correct answer is 'Noun'

Key Points

• The underlined phrase "what to say to her" functions as the object of the verb "knew," indicating something that Mr. Carr is unsure about.
• Noun clauses serve the function of a noun in a sentence and can act as subjects, direct objects, indirect objects, predicate nominatives, or objects of a preposition.
• In this context, "what to say to her" is acting as a direct object of the verb "knew," explaining what Mr. Carr hardly knew. This is characteristic of how a noun or a noun phrase would function in a sentence.
• Unlike adjective clauses that describe nouns or pronouns and adverb clauses that modify verbs, adjectives, and adverbs by showing relationships like time, reason, or condition, this clause is providing the content or substance of Mr. Carr's knowledge, thus functioning as a noun clause.
• Principal clauses, also known as independent clauses, are clauses that can stand alone as a sentence. The underlined phrase does not stand alone but is part of a larger sentence, dependent on the main clause for its meaning.

Therefore, the correct answer is 'Option 4’.

The correct answer is 'Both (a) and (b) are right.'

Key Points

• Mr. Carr explicitly expresses his intent to involve the authorities by stating, "I am going to get a cop. That's what I ought to do." This directly signifies his plan to have Alfred arrested, confirming statement (a).
• Mrs. Higgins advocates for an alternative approach to discipline, implying that understanding and guidance might be more beneficial. She hints at this by suggesting, "a little good advice is the best thing for a boy when he is at a certain period in his life," endorsing statement (b) that she wanted Alfred to be given a chance to reform.
• The dialogue between Mrs. Higgins and Mr. Carr shows a contrast in their approaches to Alfred's misdemeanor, highlighting the difference in their perspectives clearly.
• Mrs. Higgins' approach suggests belief in reformation and the potential positive impact of guidance over punitive measures.
• Mr. Carr's stance shows a belief in the effectiveness of direct consequences like arrest for wrongdoings.

Therefore, the correct answer is 'Option 1'.

• Example of Metaphor: "He’s in the twilight of his career."
• A metaphor is employed here. "Exits and entrances" are theatrical terms used to describe the actions of coming on and off stage.
• By using the terms "exits" and "entrances," Shakespeare metaphorically compares the process of birth and death to entering and leaving a stage, aligning with the ongoing metaphor of life as a theatre production.

Therefore, the correct answer is 'Option 4'.

The correct answer is 'He feels emotionally charged.'

Key Points

• A furnace generates a great amount of heat, symbolizing the warmth and fervor of the lover's feelings.
• This simile emphasizes the depth of the lover's emotional state and passion, which is consuming and intense like the heat from a furnace.
• This figure of speech helps to vividly conjure the image of a lover overwhelmed by passionate feelings, underscoring the theme of life's stages and the roles individuals play in each.
• By associating the lover with a furnace, Shakespeare communicates the idea of love as an overpowering force that can engulf a person.
