UGC NET Paper 1: Held on 13th Oct 2022 Shift 2 (Previous Year Paper)

Important Points 

21^st Century Higher Education teachers must ensure that they prepare students for

• Higher Order Thinking Skills,
• use digital resources,
• adopt an interdisciplinary approach to teaching and learning.

The other options are not true for the following reasons:

B - Placements of students:

• Placements of students are not necessarily the primary responsibility of a higher education teacher.
• While some teachers may be involved in helping students find internships or job opportunities, this is not a universal responsibility nor a defining characteristic of a 21^st Century Higher Education teacher.

D - Interaction with bright students only:

• A 21^st Century Higher Education teacher should aim to create an inclusive and diverse learning environment where all students can learn and grow.
• Focusing only on bright students and excluding other students is not a responsible approach to teaching and learning.

Key Points 

A - Preparing students towards Higher Order Thinking Skills:

• In the 21^st century, education needs to move beyond rote memorization and basic knowledge recall.
• Teachers must equip students to think critically, analyze information, evaluate evidence, and solve complex problems.
• Higher Order Thinking Skills (HOTS) is essential for students to succeed in the modern world. A 21^st Century Higher Education teacher must ensure that their teaching strategies foster these skills in students.

C - Using digital resources:

• With the advent of technology and the internet, digital resources have become integral to education.
• A 21^st Century of Higher Education teachers must use technology to enhance teaching and learning.
• This includes using digital resources such as online lectures, eBooks, podcasts, videos, simulations, games, online collaboration tools, and learning management systems.

​E - Inter-disciplinary approach:

• In the 21^st century, problems are becoming increasingly complex and require a multi-disciplinary approach.
• A 21^st Century Higher Education teacher must encourage an interdisciplinary approach to teaching and learning, where students learn to apply concepts and skills from different disciplines to solve real-world problems.
• This approach helps students to develop a broader perspective and more creative and innovative solutions.

​​The correct Option is 1) A, C, and E only.

Option 2) Limited domain is the correct answer.

Important Points

A theory is a well-substantiated explanation of some aspect of the natural world that is based on empirical evidence and has been repeatedly tested and confirmed through observation and experimentation. It provides a framework for understanding and predicting phenomena, and may be modified or replaced as new evidence becomes available.

Middle-range theories operate in a limited domain of research.

• Middle-range theories are also known as practice theories because they have less abstraction than grand theories and bridge between theory and practice in nursing.
• When used as a framework, middle-range theories help to map the concepts and relationships between them at a narrower scope than grand theories.
• A research framework helps to explain the concepts of the phenomenon under investigation. It helps draw a conceptual map of the relationships between concepts.
• They are more specific and focused than grand theories, which attempt to explain broad aspects of human experience, but are more general and abstract
• Middle-range theories are designed to explain specific phenomena within a particular context, and they provide a framework for organizing and interpreting data.
• They are often used to guide empirical research and help researchers develop testable hypotheses.
• Middle-range theories can be used across multiple disciplines and are particularly useful in fields such as sociology, nursing, and education

Additional Information

There are several types of theories that can be used in research, including:

• Grand theories: these are broad and general theories that attempt to explain broad aspects of human experiences, such as the nature of society, culture, or human development.
• Micro-level theories: these theories focus on small-scale phenomena and tend to be more specific than grand theories.
• Macro-level theories: these theories focus on large-scale phenomena and tend to be more general than micro-level theories.
• Structural-functional theories: these theories focus on how different parts of a social system work together to maintain social order.
• Conflict theories: these theories focus on how social inequality and power imbalances contribute to social conflict and change.
• Symbolic interactionism: this theory focuses on how people interact with each other through shared symbols and meanings.
• Rational choice theory: this theory focuses on how people make decisions based on their preferences and constraints.

Option 1) C, D, and E only suggest that the following factors contribute to poor analysis in historical research:

 Important Points

C. Over-generalisation

This refers to drawing broad conclusions based on limited evidence or extrapolating from a few examples to make sweeping statements about an entire historical period or culture. Over-generalization occurs when a historian makes sweeping statements or draws broad conclusions based on limited evidence or small sample size. This can lead to inaccurate or incomplete understandings of historical events and trends.

D. Over-simplification

Over-simplification may lead historians to ignore the nuances and complexities of historical events and trends, resulting in incomplete or inaccurate understandings.

E.  Over-simplification

Over-simplification may lead historians to ignore the nuances and complexities of historical events and trends, resulting in incomplete or inaccurate understandings.

Non-identification of social context can result in historians failing to consider how social, economic, political, and cultural factors shaped historical events and impacted the individuals and groups involved.

These factors highlight some common pitfalls that historians may encounter in their research. By being mindful of these factors and taking a nuanced and comprehensive approach to historical research, historians can develop accurate and meaningful interpretations of past events and their impact on the present.

Key Points

Historical research consists of studies of past happenings. In one sense, the study of history highlights causal relationships of past events and outlines enough background for understanding the social phenomena, past and present. 

The main feature of historical research is the evaluation of historical data. The backbone of historiography is the authenticity of data collected through different sources. Even when the data are collected through different sources, doubts about their validity, reliability, and relevance can be raised. The process of judging data's validity, reliability, and relevance is carried out through two devices viz. External Criticism and Internal Criticism. 

Historical research design

• It is qualitative research.
• Historical research is the study and analysis of past events to predict the future.
• It involves systematically collecting and objectively evaluating data related to past events.
• It is a process of reconstructing the past.
• The historian collects data, analyses them, and then comes to conclusions about the tenability of the hypothesis.
• The researcher analyses the previous information or events minutely and tests their validity.

the correct answer is option 1) Both Statement I and Statement II are true.

Important Points

Statement I: Personal conversation is more effective than a broadcast speech.

• This statement is generally true because personal conversations involve direct, two-way communication between individuals, which allows for more opportunities for feedback and clarification.
• In contrast, broadcast speeches are typically one-way communication, where the speaker delivers a message to a large audience without direct interaction.
• While broadcast speeches can be effective in reaching a large audience, they may not be as effective in engaging individuals on a personal level.

Statement II: The factor of personalization makes the radio a more effective means of communication than a newspaper.

• This statement is also true to some extent.
• Radio can offer a more personalized experience through its use of audio and human voice.
• The voice of a radio personality can create a sense of intimacy and connection with the listener that can be difficult to achieve through text-based media such as newspapers.
• However, newspapers can also offer a personalized experience through targeted content and features such as opinion pieces and letters to the editor.

The effectiveness of communication is not solely determined by the medium used but also by factors such as the target audience, the message being conveyed, and the context of the communication

Additional Information

Effective communication:

• Effective communication is a two-way process that includes transmitting and receiving accurate messages.
• The most vital component of effective communication is an accurate message.
• An accurate message is one that relays the exact points you wanted to make without including any clutter that might distort the message.
• An accurate message is also received and interpreted correctly.

Qualities of an effective communicator:

• Observance: A person must possess sharp observing skills to gain more and more knowledge and information.
• Clarity and Brevity: The message must be drafted in simple words, and it should be clear and precise to create the desired impact on the receiver.
• Listening and Understanding: The most crucial skill in a person is must be a good, alert, and patient listener. He must be able to understand and interpret the message well.
• Emotional Intelligence: A person must be emotionally aware and have the ability to influence others from within.
• Self-Efficacy: Also, he/she must have faith in himself and his capabilities to achieve the objectives of communication.
• Self-Confidence: Being one of the essential communication skills, confidence enhances the worthiness of the message being delivered.
• Respectfulness: Delivering a message with courtesy and respecting the values, beliefs, opinions, and ideas of the receiver are the essence of effective communication.

Option 1) Bloom's Taxonomy represents learning as a six-level hierarchy in a cognitive domain. 

Important Points

B. S. Bloom has divided the cognitive objectives into six categories (under Bloom's taxonomy) arranged from the lowest to the highest level of functioning.

Stages  Subdomains of Cognitive Domain:

• Knowledge: It refers to the process of recognizing and recalling information.
• Comprehension: It refers to the process of interpreting and assimilating information.
• Application: It refers to utilizing information in new and different situations.
• Analysis: It refers to the process of identifying the pattern and connection among the given information
• Synthesis refers to combining information and making connections among them to generate a new idea.
• Evaluation: It refers to the process of making judgments and Justifying decisions about the value of information and materials

Thus, Bloom's Taxonomy represents learning as a six-level hierarchy in a cognitive domain.

Key Points

B.S. Bloom has proposed a taxonomy, a set of three hierarchical models that refers to the classification of educational learning objectives.

Bloom's Taxonomy Identified Three Domains of Learning:

1. Cognitive Domain: It involves knowledge and the development of intellectual skills.
2. Affective Domain: It includes how we deal with things emotionally, such as feelings, values, appreciation, etc.
3. Psychomotor Domain:  It includes physical movement, coordination, and use of the motor-skill areas.

Key Points 

The curriculum evaluation model considers three primary sources of curriculum**: students, society, and subject matter,** reflecting the philosophy of education and psychology of learning is Tylor's Model.

• This model was developed by Ralph Tyler in the 1940s and has been widely used in curriculum development and evaluation.
• Tyler argued that four questions must be answered in developing any curriculum plan of instruction.
• Objectives: What educational purposes should the school seek to attain?
• Content: What educational experiences can be provided that will likely attain these purposes?
• Teaching Methods: How can these educational experiences be effectively organized?
• Evaluation: How can we determine whether the purposes are being attained?
• He has also highlighted an important set of factors to be weighed against the questions. Tyler believed that the structure of the school curriculum also had to be responsive to three central factors that represent the main elements of an educative experience:
• The nature of the learner (developmental factors, learner interests and needs, life experiences, etc.);
• The values and aims of society (democratizing principles, values, and attitudes); and
• Knowledge of subject matter (what is considered worthy and usable knowledge).

Key Points

Assessment is the process of evaluating and measuring students' learning outcomes and achievements. It provides feedback on students' understanding, skills, knowledge, and performance in a particular subject or course.

"Summative Evaluation", commonly known as  "Assessment of Learning", is a type of evaluation that:

• Measures to certify and report students' learning levels by assessing them at the end of the term.
• Produces accurately describing students' potential and achievement to promote them to the next grades.
• It comes at the end of the term, course, or teaching program. Annual and half-yearly examinations in schools and public examinations are examples of such evaluations.​

There are several types of assessments, which include:

Hence it can be concluded that Summative Assessment is done to give students grades/marks/credits.

Key Points

Auto-ethnography is an approach that combines elements of autobiography and ethnography to explore and analyze personal experien**ces.

• Personalized and contextualized references are permissible in Ethnographic Research.
• Ethnography is a study directly observing users in their natural environment rather than in a lab. This type of research aims to gain insights into how users interact with things in their natural environment.
• Ethnography is a qualitative research study looking at users' social interaction in a given environment.
• This research provides an in-depth insight into the user’s views
• Ethnography methods include direct observation, diary studies, video recordings, photography, and artefact analysis, such as devices that a person uses throughout the day.
• The goal is to see people’s behaviour on their terms, not researchers'.
• It involves using personal experiences and observations to reflect on and analyze cultural practices, social interactions, and other aspects of human experience.
• It is used to gain insights into the experiences and perspectives of individuals and groups.
• It is used in sociology, anthropology, education, and psychology.
• Auto-ethnography analyzes personal experiences.
• It combines elements of autobiography and ethnography
• It explores and analyzes cultural practices and social interactions
• It is a qualitative research method
• It emphasizes the subjective experiences of the researcher.

Personal experiences are the correct answer.

Additional Information 

• Ethnography is a branch of anthropology and the systematic study of individual cultures.
• Ethnography explores cultural phenomena from the point of view of the subject of the study.
• Ethnography is also a type of social research that involves examining the participants' behaviour in a given social situation and understanding the group members' interpretation of such behaviour.
• Ethnography includes Field notes, Participant Observation and Value Neutrality.

Ethnography:

• It is qualitative research.
• The process of studying and describing a culture (shared attitudes, values, norms, the language of a group of people) in detail.
• Data is collected through observation, or the researcher may go and live in the specific community where the research will conduct and study the culture and educational practices.
• It provides an insider's picture of a community under study.
• The researcher participates in people’s daily lives for an extended period, watching what happens, listening to what is said, and asking questions to address the issues with which he or she is concerned.

The correct answer is option 1) Both Statement I and Statement II are true.

Important Points

Statement I is true.

• Focus group discussions are a common method used in formative research, which is a type of research used to gather information and insights that can be used to develop or refine programs, interventions, or products.
• Focus groups involve bringing together a small group of individuals to discuss their attitudes, beliefs, and experiences related to a particular topic.

Statement II is also true.

• Formative research can be conducted using both qualitative and quantitative methods.
• Qualitative methods, such as focus groups, can be used to gather in-depth information about attitudes, beliefs, and behaviors, while quantitative methods, such as surveys or experiments, can be used to gather data on a larger scale.

Therefore, both statements are true, and the correct answer is option 1) Both Statement I and Statement II are true.

Key Points

Focus Group

• A Focus Group is a Qualitative Research Technique.
• It is a small group discussion guided by a trained leader.
• It aims at a discussion in regard to certain problems instead of individual responses.
• It is used to learn about opinions on a designated topic, and to guide future action.
• A focus group is a qualitative research method that brings together a small group in a room to provide feedback regarding a product, service, concept, marketing campaign, or specific problem.
• A trained moderator leads a 30-90-minute discussion within the group that is designed to gather helpful information.
• The moderator arrives with a set list of 10-12 questions that will be shared with the group during their time together that are designed to elicit thoughtful responses from all the participants
• The focus group is characterized by homogeneity, but with sufficient variation among participants to allow for contrasting opinions.
• The traditionally recommended size of the focus group is 10 to 12 people. The ideal size of a focus group for most topics is five to eight participants.
• A focus group should not involve more than 10 participants because large groups are difficult to control and they limit each person’s opportunity to share insights, observations, and opinions.

the correct option is A - IV, B - III, C - II, D - I 

Key Points

Reliability tells you how consistently a method measures something. When you apply the same method to the same sample under the same conditions, you should get the same results. If not, the method of measurement may be unreliable or bias may have crept into your research.

There are four main types of reliability. Each can be estimated by comparing different sets of results produced by the same 

The correct Option is 4) C, D, and E only.

Key Points

• The traditional approaches to communication are typically divided into three categories: rhetorical, semiotic, and phenomenological.
• Rhetorical approaches emphasize the use of language and persuasion in communication,
• semiotic approaches focus on the study of signs and symbols, and
• phenomenological approaches emphasize the subjective experiences of individuals in communication.
• Machine-to-machine and machine-to-man communication are more recent developments and do not fall under the category of traditional approaches​

Key Points 

A. Machine-to-machine:

• This refers to communication between machines or devices, which is typically automated and involves the exchange of data or information
• This type of communication is common in fields such as manufacturing, transportation, and telecommunications.
• Machine-to-machine communication is a relatively recent development and is not considered a traditional approach to communication.

B. Machine-to-man:

• This refers to communication between machines and humans, such as when a computer displays information to a user or when a user interacts with a website or application.
• While machine-to-man communication has become increasingly common in recent years, it is not considered a traditional approach to communication.

C. Rhetorical: Rhetorical approaches

• to communication emphasize the use of language and persuasive techniques to influence and persuade audiences.
• This approach has been used in various fields, including politics, marketing, and public speaking, and has a long history dating back to ancient Greece and Rome.
• Rhetorical approaches are considered a traditional approach to communication.

D. Semiotic:

• Semiotic approaches to communication focus on the study of signs and symbols, and how they are used to convey meaning.
• This approach examines how people interpret and understand different types of signs, such as language, images, and gestures, and how these signs are used in various forms of communication.
• Semiotic approaches are also considered a traditional approach to communication.

E. Phenomenological:

• Phenomenological approaches to communication emphasize the subjective experiences of individuals in communication, and how their personal experiences and perceptions shape their understanding of messages.
• This approach emphasizes the importance of understanding the context in which communication takes place, and how individuals interpret and make meaning from communication.
• Phenomenological approaches are also considered a traditional approach to communication

the correct Option is 2) Imprecise.

Important Points

Metaphors are considered imprecise in nature because they involve the use of figurative language to draw comparisons between two things that are not literally the same, and the meaning of the metaphor can be subjective and dependent on the context and interpretation of the receiver.

Communication is a process of passing information and understanding from one person to another; it is the process of imparting ideas and making oneself understood by others. In the communication process, the sender (encoder) encodes the message and then using a medium/channel, sends it to the receiver (decoder) who decodes the message, and after processing the information, the receiver sends back appropriate feedback/reply using a medium/channel.

• The word “metaphor” comes from the Greek metaphorá, which means “to transfer” or “to carry over.”
• A metaphor is a literary device that correlates two seemingly unrelated ideas in order to make the reader see them in a new way.
• Metaphors have been in practice since the dawn of literature; the Greek philosopher Aristotle considered mastery of the metaphor in writing a “sign of genius.”

Key Points

• Metaphors involve figurative language: Metaphors involve using language that is not meant to be taken literally, which can make the meaning of the metaphor subjective and open to interpretation.
• Metaphors draw comparisons between two unlike things: Metaphors compare two things that are not literally the same, which can introduce ambiguity and imprecision into the communication.
• Metaphors can be context-dependent: The meaning of a metaphor can vary depending on the situation, the individuals involved, and the context in which it is used.
• Metaphors are subjective: The meaning of a metaphor can be dependent on the interpretation of the receiver, which can make it imprecise in situations where precise communication is necessary.
• Metaphors can be open to different levels of abstraction: The comparison made in a metaphor can be open to different levels of abstraction, which can make it challenging to determine the precise meaning.
• Metaphors can be nuanced: The meaning of a metaphor can be influenced by subtle nuances and differences that can vary from person to person, which can also make it imprecise.

Concept Used:-

The percentage is a way of comparing the quantities. Suppose, 20 number is x% of y. Then, the relation between x and y can be given as,

\(\dfrac{x}{100}\times y=20\)

Explanation:-

Here, total production of Bicycle by company A,

\(\Rightarrow \dfrac{20}{100}\times64000000=12800000\)

Now ratio of L to M is 13 : 7. So, total L model production,

\(\Rightarrow \dfrac{13}{20}\times12800000=8320000\)

Now, profit earned by Company A on model L,

\(\Rightarrow \dfrac{25}{100}\times8320000=2080000=0.208\rm \ crore\)

So, the profit earned by Company A on model L is Rs. 0.208 crore.

Hence, the correct option is 3.

Concept Used:-

The percentage is a way of comparing the quantities. Suppose, 20 number is x% of y. Then, the relation between x and y can be given as,

\(\dfrac{x}{100}\times y=20\)

Explanation:-

Here, total production of Bicycle by company B,

\(\Rightarrow \dfrac{14}{100}\times64000000=8960000\)

Now ratio of L to M is 9 : 5. So, total M model production,

\(\Rightarrow \dfrac{5}{9+5}\times8960000=3200000\)

Now, profit earned by Company B on model M,

\(\Rightarrow \dfrac{30}{100}\times3200000=960000\)

Total production of Bicycle by company C,

\(\Rightarrow \dfrac{22}{100}\times64000000=14080000\)

Now ratio of L to M is 6 : 5. So, total M model production,

\(\Rightarrow \dfrac{5}{6+5}\times14080000=6400000 \)

Now, profit earned by Company C on model M,

\(\Rightarrow \dfrac{24}{100}\times6400000=1536000 \)

Total profit,

⇒ 1536000 + 960000 = 2496000 = 0.2496

So, Profit earned by Companies B and C together on Model M is 0.2496 crore.

Hence, the correct option is 1.

Concept Used:-

Explanation:-

Here, total production of Bicycle by company D,

\(\Rightarrow \dfrac{13}{100}\times64000000=8320000\)

Now ratio of L to M is 6 : 7. So, total L model production,

\(\Rightarrow \dfrac{6}{6+7}\times8320000=3840000\)

Now, profit earned by Company D on model L,

\(\Rightarrow \dfrac{35}{100}\times3840000=1344000\)

Total production of Bicycle by company F,

\(\Rightarrow \dfrac{21}{100}\times64000000=13440000\)

Now the ratio of L to M is 11 : 10. So, total M model production,

\(\Rightarrow \dfrac{10}{10+11}\times13440000=6400000\)

Now, profit earned by Company F on model M,

\(\Rightarrow \dfrac{20}{100}\times6400000=1280000\)

Required ratio,

⇒ 3840000 : 6400000 = 1344000 / 1280000

⇒ 3840000 : 6400000 = 3 : 5

So, the ratio of the cost of production of model L by Company D to that of model M by Company F is 3 : 5.

Hence, the correct option is 2.

Concept Used:-

The percentage is a way of comparing the quantities. Suppose, 20 number is x% of y. Then, the relation between x and y can be given as,

Explanation:-

Here, total production of Bicycle by company C,

\(\Rightarrow \dfrac{22}{100}\times64000000=14080000\)

Now the ratio of L to M is 6 : 5. So, total L model production,

\(\Rightarrow \dfrac{6}{6+5}\times14080000=7680000\)

Now, profit earned by Company C on model L,

\(\Rightarrow \dfrac{20}{100}\times7680000=1536000\)

Total production of Bicycle by company E,

\(\Rightarrow \dfrac{10}{100}\times64000000=6400000\)

Now the ratio of L to M is 2 : 3. So, total M model production,

\(\Rightarrow \dfrac{3}{2+3}\times6400000=3840000\)

Now, the profit earned by Company E on model M,

\(\Rightarrow \dfrac{21}{100}\times3840000=806400\)

Required distance,

⇒ 1536000 - 806400 = 729600 = 0.07296 crore

So, the difference between the profit earned by Company C on model L and by Company E on model M (in Rs. crore) is 0.07296 crore.

Hence, the correct option is 4.

Concept Used:-

The percentage is a way of comparing the quantities. Suppose, 20 number is x% of y. Then, the relation between x and y can be given as,

Now, profit earned by Company B on model L,

\(\Rightarrow \dfrac{28}{100}\times5760000=1612800\)

Total production of Bicycle by company D,

\(\Rightarrow \dfrac{13}{100}\times64000000=8320000\)

Now the ratio of L to M is 6 : 7. So, total M model production,

\(\Rightarrow \dfrac{7}{6+7}\times8320000=4480000\)

Now, profit earned by Company D on model M,

\(\Rightarrow \dfrac{25}{100}\times4480000=1120000\)

Required ratio,

⇒ 1612800 : 1120000 = 1612800 / 1120000

⇒ 1612800 : 1120000 = 36 : 25

So, the ratio of the profit earned on model L by Company B to that of model M by Company D is 36 : 25.

Hence, the correct option is 1.

Statement I: Learning Management System (LMS) provides a virtual environment for teachers and students.

Key Points

• Learning Management Systems (LMS) are software platforms that deliver educational courses and provide a virtual environment for teachers and students.
• LMS systems typically include tools for creating and managing course content, facilitating communication and collaboration between teachers and students, tracking student progress, and assessing student performance.
• The LMS can be hosted as a standalone product on the company server or as a cloud-based platform hosted by the software company.
• Some Examples of LMS software are Socrative, Mindflash, SkyPrep, ProProfs LMS, Spring Learn, TalentLMS, Docebo, Blackboard Learn, MOODLE, etc.

In the broadest sense, an LMS consists of these three terms:

• Learning: An LMS handles the learning material delivery, administration, automation, and analytics. All of this is done for one simple goal: fulfilling learning goals.
• Management: LMS holds an important role in documentation and database management. Without well-executed management of information, an LMS is doomed to fail.
• System: This refers to the LMS system as a whole that handles all the incoming and outgoing learning information within a single ecosystem.
• These three terms describe LMS in a very rudimentary manner. But, what’s most important to take away is that an LMS is defined by its ability to facilitate learning.

Statement II: LMS can be used for blended learning as well as for online learning.

Key Points

• LMS can be used for both blended learning and online learning. Blended learning combines face-to-face instruction and online learning, while online learning is conducted entirely through digital platforms.
• LMS can support both modes of learning by providing a platform for delivering course content, managing student interactions, and assessing student progress, regardless of whether the learning occurs in a physical or virtual classroom.
• LMS can also be used to support hybrid learning, where some students participate in a class in person while others join remotely through the LMS platform

Thus Both Statement I and Statement II are correct

Additional Information

Blended learning:

• Blended learning is an educational approach that combines traditional classroom instruction with online learning.
• This method allows students to learn at their own pace while allowing for interaction and collaboration with instructors and peers in a traditional setting.
• Blended learning aims to create a personalized learning experience that meets the needs of individual students.

Online Learning:

• Online learning is a mode of education that uses digital platforms and technology to deliver instructional content and facilitate student learning.
• It allows students to access course materials, participate in virtual discussions and assessments, and complete assignments from anywhere with an internet connection.
• This form of education offers flexibility and convenience for students who may not be able to attend traditional in-person classes, as well as opportunities for personalized learning and self-paced progress.

As per the UGC NET official answer key, The correct option is 3) Interpersonal communication.

 Key Points

• Homogeneity of opinion among groups of people is mostly caused by Interpersonal communication. Because interpersonal communication can also shape people's opinions and attitudes, but it is not the primary cause of homogeneity of opinion among groups of people.

Homogeneity of opinion among groups of people is often caused by various factors other than Interpersonal Communication, such as

• Social influence: It refers to the ways in which individuals can influence the attitudes and behaviours of others.
• Social conformity: Social Conformity is the tendency to adjust one's attitudes or behaviours to align with the group norms.
• Group polarization: It refers to groups' tendency to make more extreme decisions than individuals would make alone.

Important Points

Mass communication-

• Mass communication disseminates information to a large audience through various channels such as television, radio, newspapers, social media, etc.
• Mass communication can create a shared understanding and worldview among people, but it does not necessarily always lead to a sense of homogeneity of opinion.

Intra-personal communication-

• is communication with oneself, which may include self-talk, acts of imagination and visualization, and even recall and memory. it also includes thoughts, assessments, contemplations, and feelings that are associated with one's inner communication. That is why in the option above, we have chosen intrapersonal communication in one to none mode of communication.

​​Abstraction in communication-

It refers to the process of using general or abstract terms and concepts to describe complex or specific ideas or phenomena. Abstraction is often used in communication to simplify complex ideas and make them more understandable or relatable to the audience.

Additional Information 

Communication is the transfer of information from one person to another, whether or not it elicits confidence. But the information transferred must be understandable to the receiver" – G.G. Brown.

Types of Communication:

1. Verbal Communication:  Verbal communication is the use of language to pass on information by speaking. For example,  written instructions on a question paper, attending an online class, and a yoga instructor teaching yoga poses, etc.
2. Non-verbal Communication: It is understood as the process of communication through sending and receiving wordless messages. Non-verbal details reveal who we are and impact how we relate to other people. These include:
3. Appearance: Our choice of color, way of dressing/clothing, hairstyles, and other factors affecting appearance are also considered a means of nonverbal communication. These first impressions are important, which is why experts suggest that job seekers dress appropriately for interviews with potential employers
4. Facial expressions: Information can be conveyed with a smile or a frown. Non-verbal communication and behavior can vary dramatically between cultures, the facial expressions for happiness, sadness, anger, and fear are similar throughout the world.
5. Gestures: Common gestures include waving, pointing, and using fingers to indicate numeric amounts. A few of the gestures are arbitrary and related to culture. For example, a clenched fist can indicate anger or solidarity.
6. Paralinguistics: It refers to vocal communication that is separate from actual language. This includes factors such as tone of voice, loudness, inflection, and pitch.
7. Body Language (Kinesics) & Posture: Arm-crossing and leg-crossing show defensive postures. Body language is far more subtle and less definitive.
8. Proxemics: It refers to how people use and interpret space. The amount of distance we need and the amount of space we perceive as belonging to us are influenced by several factors including social norms, situational factors, personality characteristics, and level of familiarity.
9. Eye Gaze (Oculesics): Looking, staring, and blinking can also be important nonverbal behaviors. For example, when people encounter people or things that they like, the rate of blinking increases, and pupils dilate. Looking at another person can indicate a range of emotions, including hostility, interest, and attraction.
10. Haptics (Touch): It can be used to communicate affection, familiarity, sympathy, and other emotions such as holding hands, back-slapping, etc.

Concept Used:-

Ratio is the relation among two or more numbers, which tells that how much one number is bigger than the others. To solve the questions based on ratio, we use assume a variable for the shared part among quantities.

Explanation:-

Three numbers are in the ratio of 2 ∶ 5 ∶ 6. Suppose the numbers are 2x, 5x and 6x.

Given that the sum of three number is 663. Thus,

⇒ 2x + 5x + 6x = 663

⇒ 13x = 663

⇒ x = 663 / 13

⇒ x = 51

So, the numbers are,

First number 2x = 2 × 51 = 102

Second number 5x = 5 × 51 = 255

Third number 6x = 6 × 51 = 306

So, the three numbers are 102, 255 and 306.

Hence, the correct option is 3.

Concept Used:-

The average of the group of numbers is the ratio of the sum of all the numbers given to the total number.

The formula to found the average is given below.

⇒ Average = (sum of all the observation) / (Total number of observation)

Explanation:-

Suppose the age of the class teacher is x years.

Also, let sum of ages of students is y years.

Total students in the class = 15.

The average age of students and teacher = 15 years.

⇒ (x + y) / 16 = 15

⇒ (x + y) = 240        ....(1)

The average age of the teacher and the students is 2 years more than that of students. Thus,

⇒ (y / 15) + 2 = 15 

⇒ y =13 × 15 

⇒ y = 195

Put this value in equation (1),

⇒ (x + y) = 240

⇒ (x + 195)  = 240

⇒ x = 45 years

So, the age of the class teacher is 45 years.

Hence, the correct option is 4.

Concept Used:-

The formula to calculate the profit percentage of an item whose cost price is CP,

\(\Rightarrow \rm Profit \ Percentage =\dfrac{\text{Profit}\times100}{\text{CP}}\)

Explanation:-

The shopkeeper sells 750 gm instead of 1 kg. Since, there are 1000 gas in 1 kg. So, his profit,

⇒ Profit = 1000 - 750 

⇒ Profit = 250 gms

Also, his cost price is 750 gms.

So, the profit percentage,

 \(\Rightarrow \dfrac{250\times100}{750}=33.33%\)

So, his gain in percentage is 33.33%.

Hence, the correct option is 4.

Concept Used:-

The formula to calculate Simple Interest (I), on principal amount P with rate of interest (R) and time period T(in years) is,

\(I=\dfrac{PRT}{100}\)

Explanation:-

Suppose, that principal is P, Rate of interest is R% and time is T.

Now given that,

Time T = R

Simple interest SI = 4P/9.

From the formula of simple interest,

 \(\begin{aligned} &\Rightarrow S I=(P \times T \times R) / 100 \ & \Rightarrow 4P / 9=(P \times R \times R) / 100 \ & \Rightarrow 4P / 9=\left(P \times R^2\right) / 100 \ & \Rightarrow 4 / 9=\left(R^2\right) / 100 \ & \Rightarrow R^2=400 / 9 \ & \Rightarrow R=20/ 3 \ & \Rightarrow R=6\frac{2}{3}% \end{aligned}\)

So, the annual rate of interest and time are 6\(\frac{2}{3}\)% and 6\(\frac{2}{3}\) years respectively.

Hence, the correct option is 4.

LOGIC in the given series is:

Consecutive odd numbers are added in previous term to get the next term, starting from 5.

5 + 5 = 10

10 + 7 = 17

17 + 9 = 26

26 + 11 = 37

37 + 13 = 50

50 + 15 = 65

So, the wrong number is 24.

the correct  is option 2, "Some men are not dishonest."

Important Points The obverse of the proposition "Some men are honest" is "Some men are not dishonest." Therefore, the option that is obverse of and logically equivalent to "Some men are honest" is option 2, "Some men are not dishonest."

• In logic, the obverse of a proposition is formed by negating the predicate and the subject of the original proposition. The obverse of "Some men are honest" would therefore be "Some men are not dishonest," which is option 2

Option 1, "Some men are dishonest,"

• is the converse of the original proposition.
• The converse of a proposition is formed by switching the subject and predicate of the original proposition.
• While the converse of a true proposition is also true, the converse of "Some men are honest" does not necessarily have to be true because there may be other men who are neither honest nor dishonest.

Option 3, "No men are dishonest,"

• is a contradictory proposition. The contradictory proposition is formed by negating the entire proposition,
• changing "some" to "no" and negating the predicate.
• The contradictory proposition to "Some men are honest" would be "No men are honest."
• However, this is not logically equivalent to the original proposition because it is possible that only some men are honest, while the rest are not.

Option 4, "Some dishonest people are not men,"

• is an unrelated proposition.
• This proposition does not have the same subject or predicate as the original proposition and is
• therefore not obverse, converse, or​

The correct answer is option 1) Both Statement I and Statement II are true.

Key Points

Statement I: To obvert a proposition, we change its quality and replace the predicate term with its complement.

• Obversion is a logical operation used to form the contrapositive of a proposition.
• It involves changing the quality of the proposition, from affirmative to negative (or vice versa).
• The predicate term is then replaced with its complement, which is the set of all objects that are not included in the original predicate term.
• For example, the obverse of the proposition "All dogs are mammals" is "No dogs are non-mammals." The quality has been changed from affirmative to negative, and the predicate term "mammals" has been replaced with its complement "non-mammals".

Statement II: Obversion is valid for any standard form categorical proposition.

• The standard form categorical proposition can be one of four types: All A are B, No A are B, Some A is B or Some A is not B.
• Obversion can be applied to any of these propositions to create a logically equivalent contrapositive.
• For example, the obverse of the proposition "Some cats are not black" is "Some cats are black." The quality has been changed from negative to affirmative, and the predicate term "black" has been replaced with its complement, which is "non-black."

Therefore, both statements I and II are true, making option 1) the correct answer.

The logical informal fallacy committed in the given argument is option 3) Appeal to ignorance.

Important Points

• Appeal to ignorance is a fallacy that occurs when a person claims that something is true simply because it has not been proven false or that it is false simply because it has not been proven true. In other words,
• it assumes that a lack of evidence for or against a claim means that the claim is either true or false.
• In the given argument, the speaker is claiming that since no one has proved that global warming is occurring, then there is no reason to believe that it is occurring.
• This is fallacious reasoning because the absence of proof does not necessarily mean that something is not true.

Appeal to Ignorance:

• It asserts that a proposition is true because it has not yet been proven false or a proposition is false because it has not yet been proven true
• Appeal to Ignorance occurs when a person mistakenly believes something to be true that is not, because he or she does not know enough about the subject, or has not been given enough evidence, to know otherwise.
• Example: No one can actually prove that God exists; therefore God does not exist.

Key Points

• A logical fallacy is an error in reasoning that makes your argument less effective and convincing. And you want to be able to spot these fallacies in other people's arguments (and your own) so you can call them out or fix your strategy. There are two major types of logical fallacies, formal and informal.
• Formal fallacy: A defect or error traceable to the very structure or form of the argument.
• Informal fallacy: A defect that can be detected only by examining the content of the argument.​

The fallacy of equivocation:

• is an informal fallacy resulting from the use of a particular word/expression in multiple senses within an argument. It is a type of ambiguity that stems from a phrase having two or more distinct meanings, not from the grammar or structure of the sentence.
• For example, I have the right to watch "The Real World". therefore it's right for me to watch the show.

Begging the question:

• This is a fallacy that occurs when an argument's conclusion is assumed in one of its premises, rather than being proven by the argument.
• Example: "Global warming is happening because the evidence shows that the climate is changing and becoming warmer."
• In this argument, the conclusion that global warming is happening is already assumed in the premise that the climate is changing and becoming warmer.

Hasty generalization:

• This is a fallacy that occurs when a general conclusion is drawn from insufficient evidence.
• Example: "I met two rude French people, so all French people must be rude."
• In this argument, a general conclusion is drawn about all French people based on the behavior of only two individuals, which is an insufficient sample to make such a sweeping conclusion.

the correct answer is option 3)

Important Points

"Middle term itself disproves the original proposition and proves its contradictory" is not the correct reason for why the argument "Sound is eternal because it is produced" is fallacious.

• The correct reason is that the argument commits the fallacy of non sequitur, which means that the conclusion does not logically follow from the premise.
• Non sequitur is a type of logical fallacy in which the conclusion does not follow logically from the premise or premises. In other words, the conclusion does not "sequitur" or follow from the premises.
• This type of fallacy can take many different forms, but in all cases, the conclusion is not a logical consequence of the premises
• In this case, the premise that "sound is produced" does not necessarily lead to the conclusion that "sound is eternal."
• Option 1) "Middle term is contradicted by another pramana (means of knowledge)" is not applicable in this argument since there are no other means of knowledge presented to contradict the middle term.
• Option 2) "The middle term is too narrow" is also not the correct answer because the middle term "produced" is not too narrow. It is properly defined and used on both premises.
• Option 4) "The minor term is the locus of the middle term" is also not applicable in this argument. The minor term, which is "sound" is not the locus of the middle term. The middle term appears in both premises, but not in the conclusion.

So, the correct answer is option 3) "Middle term itself disproves the original proposition and proves its contradictory" is not the correct reason for why the argument is fallacious

Additional Information

A categorical syllogism consists of three terms:

• the major term (the predicate of the conclusion),
• the minor term (the subject of the conclusion),
• the middle term (which is used to connect the major and minor terms).

For example, in the syllogism "All men are mortal. Socrates is a man. Therefore, Socrates is mortal,"

the middle term is "men", which appears in both premises, but not in the conclusion.

The middle term plays a crucial role in determining the validity of syllogism. The two premises of a syllogism are used to conclude the relationship between the major and minor terms, and the middle term is the term that allows this relationship to be made. If the middle term is ambiguous or improperly defined, it can lead to errors in reasoning and an invalid syllogism.

The correct answer is Anumana (inference).

Important Points 

In Indian philosophy, there are six means of knowledge, or Pramanas used to acquire true and valid knowledge about the world. These Pramanas are:

1. Pratyaksha (perception)
2. Anumana (inference)
3. Upamana (comparison)
4. Sabda (verbal testimony)
5. Arthapatti (presumption)
6. Anupalabdhi (non-apprehension)

Key PointsOut of these six pramanas,

• Anumana or inference is differentiated into two types:
• Svartha (for oneself): Svartha Anumana refers to inferential knowledge that is obtained by an individual on his/her own
• Paratha (for others)., while Parartha Anumana refers to inferential knowledge that is obtained through the testimony of others.
• Pratyaksha or perception is a means of knowledge that directly apprehends objects or things through the sense organs, without the need for any inference.
• Upamana or comparison is a means of knowledge where a new object is understood by comparing it with a familiar object.
• Sabda or verbal testimony is a means of knowledge that involves the use of language, where knowledge is obtained through the testimony of reliable sources such as experts or scriptures.

Therefore, the correct answer is option 2)

the correct answer is option 1) A, B, and C. I apologize for any confusion caused.

Important Points

 A. This statement is correct.

• RFID technology is a wireless system that consists of two components: tags and readers. The tag contains a microchip and antenna that can transmit data wirelessly to the reader.

B. This statement is also correct.

• The reader emits radio waves through one or more antennas and receives signals back from the RFID tag.

C. This statement is correct as well.

• Passive RFID tags do not have a battery and rely on the energy from the reader's radio waves to power them.

Therefore, all three statements are correct, and the correct answer is option 1) A, B, and C

Key Points Radio Frequency Identification (RFID) is a technology that uses radio waves to passively identify a tagged object. I

• Radio Frequency Identification (RFID) is a type of passive wireless technology that allows for the tracking or matching of an item or individual.

• The system has two basic parts: tags and readers. The reader gives off radio waves and gets signals back from the RFID tag, while the tag uses radio waves to communicate its identity and other information.

• The technology has been approved since before the 1970s but has become much more prevalent in recent years due to its usage in things like global supply chain management and pet microchipping.

• It is a technology that uses radio waves to automatically identify various tagged objects.

• It is a wireless tracking method that uses tags and readers to track objects.

• The Low Frequency, High Frequency, and Ultra-High Frequency bands are used by RFID systems

Components: 

• Transponder,
• receiver, and
• transmitter.

Functioning: 

• The RFID reader continually sends radio waves of a specific frequency in the RFID system.
• If the object to which the RFID tag is attached is within the range of the radio waves, it provides feedback to the RFID reader, which then identifies the object based on the feedback.

Additional Information 

​There are three types of RFID tags that are commercially available.

• Passive tags: There is no power supply for passive tags. They acquire their power from the readers’ incoming radio waves.
• Passive RFID tags do not have a battery and are powered by the reader.
• Semi-passive tags: Semi-passive tags comprise an internal circuit with a power source, but rely on the radio waves received from the reader to transmit the response.
• Active tags:  The internal circuit of active tags is powered by a power source.
• Batteries are being used to power active RFID tags. It also utilizes its own power supply to send the response to the reader.

The correct answer is option 4) A, B, and D only. 

Important Points

Primary storage:

• Primary storage is the volatile storing mechanism of a computer system.
• It can refer to random access memory (RAM), and processor. cache memory, or data buses, but it is most often connected with RAM.
• Primary storage is Fast and expensive as compared to secondary storage.
• The primary memory (hard drive, RAM) is where the operating system is stored.

 Processor Registers:

• Processor registers are small, high-speed memory locations within the processor that hold data for quick access.
• They are used by the processor to store data that is frequently accessed, such as the current instruction being executed or the results of calculations.
• Registers are volatile, meaning they require power to retain their data.
• When power is lost, the data held in the registers is lost as well.
• Registers are an essential part of the processor, and the number performance of the processor and the **size of the registers can impact the processor.**​

Cache Memory:

• Cache memory is a small amount of high-speed memory that is used to temporarily store frequently accessed data.
• The purpose of cache memory is to speed up data access and reduce the number of times data needs to be retrieved from slower memory such as RAM or storage devices.
• Like processor registers, cache memory is volatile and requires power to retain its data. When power is lost, the data held in the cache memory is lost as well.
• There are different levels of cache memory, with each **level providing a larger but slower cache that is accessed if the smaller, faster cache does not have the requested data.**​

RAM:

• RAM stands for Random Access Memory, which is the main memory of a computer.
• RAM is volatile, meaning it requires power to retain its data. When power is lost, the data held in RAM is lost as well.
• RAM is used by the processor to store data that is currently being used by the computer, such as applications and open files.
• The amount of RAM in a computer can impact its performance, as more RAM allows the computer to handle more data at once

Therefore, the correct answer is option 4) A, B, and D only, as these are the hardware components that will lose data when the power to a computer is switched off.

Additional Information

Secondary storage:

• Secondary storage is non-volatile, permanent memory that is not immediately accessible by a computer or processor.
• It enables users to store data and information that can be quickly and conveniently retrieved, communicated, and used by apps and services.
• Secondary memory can be external devices such as CDs, floppy magnetic discs, and so on.
• Secondary storage is also known as external memory storage since it cannot be accessed directly by the CPU.

SSD:

• SSD stands for Solid State Drive, which is a type of non-volatile storage device that uses flash memory to store data.
• Unlike traditional hard disk drives (HDDs), SSDs do not have any moving parts, which makes them faster and more reliable.
• SSDs are non-volatile, meaning they do not require power to retain their data. When power is lost, the data stored on an SSD will not be lost.
• SSDs are commonly used in laptops and desktops as well as other electronic devices such as cameras and smartphones

ROM:

• ROM stands for Read-Only Memory, which is a type of non-volatile memory used to store firmware and other essential system software.
• Unlike RAM, ROM is not typically used for storing data that changes frequently.
• ROM does not require power to retain its data, so the data stored on it will not be lost when the power is switched off.
• ROM is used to store the BIOS (Basic Input/Output System) firmware, which is essential to boot the computer and start up the operating system.

The correct answer is option 3) Cyberstalking.

Important Points 

• Cyberstalking is the use of electronic communication by a person to follow a person, or
• attempts to contact a person to foster personal interaction repeatedly despite a clear indication of disinterest by such a person;
• or monitors the internet, email or any other form of electronic communication commits the offense of stalking.
• Cyberstalking is a type of cybercrime that involves using technology to harass or intimidate someone.
• It can include a range of behaviors such as unwanted emails, messages, or social media posts, tracking someone's online activity, or even using technology to monitor someone's physical location.
• What makes cyberstalking a cyber exacerbated crime is the use of technology to carry out these behaviors.

Additional Information

Cybercrime is a crime involving computers and networks. The computer may have been used in the execution of a crime or it may be the target

Cybercrime may be defined as “Any unlawful act where computer or communication device or computer network is used to commit or facilitate the commission of a crime”.

Most cybercrime falls under two main categories:

• Criminal activity that targets computers.
• Criminal activity that uses computers​

Option 4) Cations in the water is the correct answer.

Important Points

• The hardness of water refers to the concentration of certain minerals, typically calcium and magnesium ions, in the water.
• These ions are cations, which have a positive charge, and they can react with other compounds in the water to form insoluble mineral deposits, making the water hard.
• Hard water can cause issues with soap lathering, plumbing buildup, and other household uses.

The hardness of water: The hardness of water is that characteristic that prevents the formation of sufficient leather or foam.

• It occurs due to the presence of carbonates, bicarbonates, sulfates, and chlorides of calcium and magnesium(Ca and Mg).
• The hardness of water is due to the presence of dissolved minerals of Ca2+, Mg2+, Al3+, Iron, and other heavy elements. Specifically due to Calcium Sulphate, Calcium Bicarbonate, Calcium chloride, Magnesium Sulphate, Magnesium Bicarbonate, and Magnesium chloride

Key Points

Hardness is of the following two types-

Temporary hardness (Carbonate hardness):

• Temporary hardness is caused by the presence of dissolved bicarbonates of Calcium (Ca(HCO3)2 ), Magnesium (Mg(HCO3)2 ), Iron, and other heavy elements.
• It can be eliminated by mere boiling.
• Ca(HCO3)2 → CaCO3↓ + H2O + CO2 ↑
• Mg(HCO3)2 → MgCO3 + H2O + CO2 ↑
• MgCO3 → Mg(OH)2↓ + CO2 ↑

Permanent Hardness (non-carbonate hardness):

• Permanent Hardness is due to the presence of dissolved chlorides and sulfates of Calcium, Magnesium, Iron, and other heavy elements.
• It cannot be eliminated by boiling

Degree of Hardness

• The degree of hardness is the extent of hardness.
• It is expressed as weight in milligrams of CaCO3 equivalent to all hardness-causing substances in one million milligrams of water. That is parts per million (ppm). Or it can be expressed as weight in milligrams of CaCO3 equivalent to all hardness-causing substances in one liter of water.​

Option 1) 10 dB is the correct answer.

Reducing the intensity of noise by a factor of 10 will result in a reduction in noise level by 10 dB.

Important Points 

This is because the decibel (dB) scale is logarithmic, which means that a 10 dB increase corresponds to a ten-fold increase in sound intensity, while a 10 dB decrease corresponds to a ten-fold decrease in sound intensity. Therefore, reducing the intensity of noise by a factor of 10 corresponds to a 10 dB reduction in sound level.

The relationship between sound intensity (I) and sound level (L) is expressed in decibels (dB) using the following formula:

L = 10 log10(I/I0)

• where I0 is the threshold of human hearing, which is equal to 1x10^-12 W/m^2.
• When the intensity of a sound is reduced by a factor of 10, it means that the new intensity is one-tenth of the original intensity. Therefore, the new intensity (I') is equal to:
• I' = I/10
• Using the sound level formula, we can calculate the new sound level (L') by substituting the new intensity (I'):

L' = 10 log10(I'/I0) = 10 log10((I/10)/I0) = 10 log10(I/I0) - 10 log10(10) = L - 10 dB

So, reducing the intensity of noise by a factor of 10 results in a reduction of 10 dB in sound level.

• For example, if the initial sound level was 80 dB, reducing the intensity by a factor of 10 would result in a new sound level of 70 dB (i.e., 80 dB - 10 dB).
• Similarly, if the initial sound level was 90 dB, reducing the intensity by a factor of 10 would result in a new sound level of 80 dB (i.e., 90 dB - 10 dB)

Key Points 

Noise pollution is considered to be any unwanted or disturbing sound that affects the health and well-being of humans and organisms. Loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress

• Grades of ambient noise pollution are as follows according to noise pollution control and Regulations Rules 2000;
• Industrial areas: 70-75 dB
• Commercial areas: 55-65 dB
• Residential areas: 45-55 dB
• Silence zone: 40-50 dB
• Indoor limit: <30 dB According to WHO
• Noise greater than 75 dB over long exposure can cause hearing damage.
• Noise above 120 dB can cause biochemical changes in human bodies.
• The decibel (dB) is a logarithmic unit used to measure sound level.
• It is also widely used in electronics, signals, and communication.
• In ordinary usage, the specification of the intensity of a sound implies a comparison of the intensity of the sound with that of a sound just perceptible to the human ear.
• In simple terms, the dB is the ratio between two power levels expressed in logarithmic terms in relation to some reference level.
• For example, if given two known power levels, P2 and P1, the relative value of P2 with respect to P1 in dB is given by:
• dB = 10 log 10 (P2/P1)
• Noise levels below 35–40 dB are usually necessary for a good night’s sleep.
• A busy office may be about 60 dB while the noise level on a footpath beside a busy road might be approximately 75 dB.
• A departing jumbo jet may result in 120 dB being recorded along the runway.

Crystalline silicon (c-Si) dominates the wafer-based solar cells. On the other hand, amorphous silicon (a-Si) plays a vital role in thin-film solar cells. Yet, both types of solar cells employ silicon.

Key Points

Statement I: Photovoltaic cells are often made up of crystal silicon.

• Crystal silicon is a common material used in photovoltaic cells due to its high efficiency in converting sunlight into electricity.
• Silicon is, by far, the most common semiconductor material used in solar cells, representing approximately 95% of the modules sold today.
• It is also the second most abundant material on Earth (after oxygen) and the most common semiconductor used in computer chips.

Hence statement I is correct.

Statement II: Photovoltaic cells are also made up of inexpensive amorphous silicon, which is like ordinary glass and has no crystal properties.

• Amorphous silicon is another material commonly used in photovoltaic cells, especially for thin-film solar cells.
• It is cheaper to produce than crystal silicon and has the advantage of being flexible and lightweight.
• While amorphous silicon lacks the crystalline structure of crystal silicon, it can still efficiently convert sunlight into electricity.

Hence statement II is correct.

Both Statement I and Statement II are correct is the most appropriate answer.

Key Points 

Hansa Mehta Committee was appointed by the National Council for Women Education in 1962 under the chairmanship of Smt. Hansa Mehta. It was aimed at carefully examining the differentiation of curriculum for boys and girls at all stages of education. The Committee analysed the issues and made the following recommendations.

• Home Science is a useful subject for girls at the Higher Secondary level, but it should not be made compulsory.
• Music, Drawing, Painting and Fine Arts are the subjects of interest for girls; therefore, proper teaching facilities should exist in educational institutions.
• Girls in sufficient numbers should be encouraged to take Science and Mathematics subjects.
• In the place of Physical Education, Handwork should form a part of girls' education.
• Steps should be taken to appoint women teachers in all educational institutions at the Secondary and university stages.20 As a general dissatisfaction was found in women’s education in the Southern states of India, the Bhaktavatsalam Committee was appointed to study and suggest remedial measures

Hence option 2 is the correct answer.

The correct answer is Nitrogen dioxide.

 Key Points Nitrogen dioxide (NO2) is a toxic gas that can irritate the respiratory system and aggravate respiratory diseases such as asthma and bronchitis.

• It is one of the major pollutants that contribute to the formation of smog and atmospheric discoloration.
• NO2 is produced mainly by burning fossil fuels, particularly in motor vehicles and power plants.
• It can react with other compounds in the atmosphere to form ozone, which is also a respiratory irritant and a major component of smog.

Carbon monoxide

• is a colorless, odorless gas that is also toxic and can cause respiratory problems,
• but it is not a major contributor to atmospheric discoloration.

Lead

• is a toxic metal that can cause a wide range of health problems,
• but it is not a major contributor to respiratory problems or atmospheric discoloration.

Ozone

• is a secondary pollutant formed by the reaction of NO2 and other pollutants in the presence of sunlight, and it can cause respiratory problems,
• but it is not the primary cause of atmospheric discoloration

​therefore The correct answer is option 3) Nitrogen dioxide

Additional Information

• nitrogen oxides are also a precursor for a number of harmful secondary air pollutants,
• including nitric acid, the nitrate part of secondary inorganic aerosols, and photo oxidants (including ozone).
• The situation is also complicated by the fact that photochemical reactions take some time (depending on the composition of the atmosphere and meteorological parameters)
• air can travel some distance before secondary pollutants are generated. These relationships are shown schematically in Figure

Figure  Simplified relationship of nitrogen oxides emissions with the formation of NO2 and other harmful reaction products including O3 and PM

Health risks from nitrogen oxides may potentially result from NO2 itself or its reaction

The correct answer is option 1) Both A and R are correct and R is the correct explanation of A.

Important Point

Assertion A

• Biomass is an organic matter that can be used as a renewable source of energy. When biomass is burned or decomposed, it releases carbon dioxide into the atmosphere.
• However, this carbon dioxide is part of the natural carbon cycle, where plants absorb carbon dioxide from the atmosphere through photosynthesis and store it in their biomass.
• Therefore, when biomass is burned, it releases carbon dioxide that was previously absorbed from the atmosphere, resulting in no net increase in atmospheric carbon dioxide levels.
• This is why biomass is considered carbon neutral.

Reason R explains this concept correctly.

• The amount of carbon emitted by burning or decomposing biomass is equal to the amount of carbon the plants absorbed from the atmosphere during their lifetime.
• Therefore, Assertion A is correct, and Reason R is the correct explanation of A.​

Key Points

• Biomass energy is formed through photosynthesis.
• Biomass is renewable organic material that comes from plants and animals.
• Biomass contains stored chemical energy from the sun.
• Biomass can be burned, however, it must be dried. This chemical process is called torrefaction.
• Biomass is the only renewable energy source that can be converted into liquid biofuels such as ethanol and biodiesel.
• Ethanol is made by fermenting biomass that is high in carbohydrates, such as sugar cane, wheat, or corn.
• Biodiesel is made by combining ethanol with animal fat, recycled cooking fat, or vegetable oil.
