The learning styles according to Fleming's VARK model of learning is Visual, Auditory, Reading/writing, Kinesthetic.

Important Points

Fleming's VARK model of learning identifies four primary learning styles, which are:

1. Visual (V): This learning style involves using visual aids such as diagrams, charts, graphs, and videos to learn and understand new concepts.
2. Auditory (A): This learning style involves learning through listening and hearing, such as through lectures, discussions, and audio recordings.
3. Reading/Writing (R): This learning style involves learning through reading and writing, such as by taking notes, writing essays, and reading textbooks.
4. Kinesthetic (K): This learning style involves learning through physical activity and movement, such as by doing experiments, participating in role-plays, and using manipulatives.

Fleming's VARK model suggests that individuals may have one or more of these primary learning styles, and that teachers and learners can use this information to adapt teaching and learning methods to suit individual preferences and needs.

The curriculum development models come under Non technical, Non-scientific category are

A. Open Classroom Model

C. Roger's Model of Interpersonal Relations

D. Weinstein and Fantini Model

Important Points

Open Classroom Model:

• The Open Classroom Model is an educational approach that emphasizes student-centered learning and the creation of a flexible and collaborative learning environment.
• In this model, students are encouraged to take an active role in their own learning and to work collaboratively with their peers and teachers.
• The Open Classroom Model originated in the 1960s and 1970s as a response to traditional classroom structures that were viewed as too rigid and teacher-centered.

Some key features of the Open Classroom Model include:

• Flexible learning spaces
• Student choice and autonomy
• Collaboration and social interaction
• Multidisciplinary learning
• Student-centered assessment

Roger's Model of Interpersonal Relations:

• Carl Rogers was a prominent American psychologist who developed a model of interpersonal relations known as the Rogerian model.
• This model emphasizes empathy, authenticity, and a non-judgmental attitude in communication and human relationships.
• According to Rogers, the key to effective interpersonal relations is empathic understanding.
• This involves putting oneself in another person's shoes and attempting to understand their experiences, feelings, and perspectives.
• Rogers believed that when individuals feel understood, they are more likely to open up and share their own experiences and feelings, leading to deeper and more meaningful connections.

Weinstein and Fantini Model:

• The Weinstein and Fantini Model is a framework for understanding intercultural competence, or the ability to communicate effectively and appropriately with people from different cultural backgrounds.
• The model was developed by Michael Weinstein and Alvino Fantini in the 1990s and has since been widely used in the field of intercultural communication.

The Weinstein and Fantini Model consists of four interconnected components:

1. Motivation
2. Attitude
3. Knowledge
4. Skills

The Weinstein and Fantini Model is often used as a guide for developing intercultural training programs and for assessing an individual's level of intercultural competence. 

Additional InformationTaba's Model:

• Hilda Taba first suggested the Taba Model in 1971 for use by teachers in the classroom, and she also wrote about it in her 1962 book Curriculum Development: Theory and Practise.
• The Taba model considers the following six factors, to guide curriculum design:

1. external factors,
2. content,
3. objectives,
4. teaching strategies,
5. learning experiences, and
6. evaluative measures.

It applies a non-linear approach to curriculum design, meaning components can be developed in any order that best fit the needs of the course or program.

The only scale of measurement that contains an absolute zero is the ratio scale.

Key PointsRatio Scale:

• In a ratio scale, the zero point represents the absence of the attribute being measured.
• This means that ratios between values on this scale are meaningful and can be used for mathematical calculations.
• Examples of ratio scales include measures of weight, height, distance, and time.

Additional Information

• In contrast, the other three types of scales of measurement (nominal, ordinal, and interval) do not have an absolute zero.
• For example, in an interval scale, such as the Fahrenheit temperature scale, zero does not indicate the complete absence of temperature but rather is an arbitrary point on the scale.
• Similarly, in an ordinal scale, such as a rank order of preference, there is no true zero point or equal intervals between the values.
• In a nominal scale, such as gender or race categories, the values are categorical and cannot be quantified in terms of numerical values or distances.

Rahul was trying to solve some mathematics problems related to trigonometry. He tried many times but failed. His teacher helped him, which led him to follow right approach and he succeeded to solve these problems. This is an example of- Zone of the proximal development.

Key PointsZone of the proximal development:

• The zone of proximal development (ZPD) is a concept developed by Lev Vygotsky, a Russian psychologist, to describe the area of learning that occurs when a person is working to acquire a new skill or knowledge, with the guidance and support of someone who is more experienced.
• It refers to the gap between what a learner can do without assistance and what they can achieve with the support of an experienced guide, usually a teacher or a peer.
• The ZPD is considered to be the most effective area for learning, as it helps learners develop new skills and knowledge by building on what they already know with the help of someone more experienced.

Additional InformationEquilibrium:

• In the context of education and development, equilibrium refers to a state of balance and stability in the learning and development processes of individuals.
• The concept of equilibrium is related to the theory of cognitive development proposed by Jean Piaget.

Assimilation:

• In education and learning, assimilation is a cognitive process in which an individual incorporates new information or experiences into their existing knowledge or schema.
• This process is a fundamental aspect of Jean Piaget's theory of cognitive development, which suggests that learning and development occur through the process of assimilation and accommodation.

Schemas:

• In psychology, a schema (plural: schemata) is a mental framework or concept that individuals use to organize and interpret incoming information from the environment.
• Schemas are based on an individual's prior experiences, knowledge, beliefs, and assumptions, and they play a crucial role in cognitive processes such as perception, memory, and problem-solving.

SWAYAM is a platform that facilitates hosting of all the courses, taught in classrooms from 9^th class onwards to be accessed by anyone, anywhere at any time.

 Important Points

• The courses on the SWAYAM platform are prepared by the best teachers in the country and are available free of cost to the learners.
• The platform offers a wide range of courses in various subjects, including arts, science, engineering, management, and humanities, among others.
• SWAYAM (Study Webs of Active Learning for Young Aspiring Minds) is an initiative of the Government of India to provide free online courses to learners across the country.
• The platform is designed to provide high-quality education and skills training to anyone, anywhere at any time.
• The courses on SWAYAM are offered in a variety of formats, including video lectures, interactive e-books, assignments, quizzes, and discussion forums.

Hence, the correct answer is class 9^th till the post- graduation.

Robustness is concerned with External validity.

Key PointsRobustness:

• Robustness refers to the ability of a statistical model or method to produce valid and reliable results even in the presence of outliers, errors, or other forms of data that do not conform to the assumptions of the model.
• In statistical analysis, robustness is important because it allows researchers to account for the inherent variability and uncertainty in real-world data, which may be subject to measurement error, missing data, or other forms of noise or variability.
• A robust statistical method is one that can still produce accurate results in the face of such challenges.

External validity:

• External validity is the extent to which the results of a study can be generalized or applied to other populations, settings, or contexts beyond the specific sample or situation studied.
• In other words, external validity refers to the degree to which the findings of a study are relevant and applicable to the real world beyond the study itself.

Additional InformationInternal validity:

• Internal validity refers to the degree to which a research study is free from bias and confounding variables, and can therefore establish a causal relationship between the independent and dependent variables.
• In other words, internal validity is concerned with the accuracy and reliability of the conclusions drawn from a study.

Measurement validity:

• Measurement validity refers to the degree to which a measure or instrument accurately measures or assesses the construct it is intended to measure.
• In other words, measurement validity is concerned with the accuracy and precision of a measurement tool in capturing the phenomenon or concept of interest.

Construct validity:

• Construct validity is a type of measurement validity that refers to the degree to which a measure accurately captures the underlying construct or concept being studied.
• In other words, construct validity is concerned with the extent to which a measure actually measures the construct it claims to measure.

A sampling technique in which initially sampled respondents contact and recruit others in their social network for participation in the research is called Snowball sampling.

Key Points Snowball sampling:

• Snowball sampling is a non-probability sampling technique in which participants are selected based on referrals from other participants.
• In other words, researchers begin by selecting a small group of individuals to participate in a study and then ask them to refer other individuals from their social network who may also be interested in participating.
• This method is often used when it is difficult to identify and access the population being studied.
• One advantage of snowball sampling is that it can provide access to hard-to-reach populations or individuals who may be hesitant to participate in research.
• It can also help to identify unique perspectives and experiences that may not have been identified through other sampling methods.
• Additionally, snowball sampling can be a cost-effective and time-efficient way to recruit participants for a study.

Additional InformationConvenience sampling:

• Convenience sampling is a non-probability sampling technique in which participants are selected based on their availability and willingness to participate in a study.
• In other words, researchers select participants who are easily accessible and readily available to participate, such as students in a particular class or customers in a certain store.

Quota sampling:

• Quota sampling is a non-probability sampling technique in which participants are selected based on pre-defined quotas for certain characteristics, such as age, gender, education level, or occupation.
• This method is often used when it is not possible to obtain a random sample, such as in field research or when the population is too large to sample in its entirety.

Systematic sampling:

• Systematic sampling is a probability sampling technique in which participants are selected from a list or population using a fixed interval.
• In other words, researchers choose a starting point at random, and then select every nth participant from the list or population.
• For example, if every fifth participant is selected from a list of 100 participants, the sample size would be 20.

Statement I is incorrect but Statement II is correct.

Important Points

Statement I: Debriefing of participants takes place at the beginning of a study.

• Debriefing of participants typically takes place at the end of a study, after all data has been collected.
• Debriefing is a process that involves providing participants with information about the study, including its purpose, procedures, and any potential risks or benefits.
• It also provides an opportunity for participants to ask questions and provide feedback.
• Debriefing is an important ethical consideration in research, as it helps to ensure that participants are fully informed about the study and its implications.
• It also provides a mechanism for researchers to address any concerns or issues that may arise during the study, and to ensure that participants understand their rights and responsibilities.

Hence, this statement is incorrect.

Statement II: Deception is the practice of giving false information to research participants about some aspect of the study.

• Deception is the practice of deliberately providing false or misleading information to research participants about some aspect of the study.
• This may include misleading participants about the purpose of the study, the procedures involved, or the potential risks or benefits.
• Deception is sometimes used in research to avoid participant bias or to create a more realistic experimental situation.
• However, it is generally considered to be unethical and is subject to strict regulations and guidelines.

Hence, this statement is correct.

The linear model of communication can be described as Authoritarian.

Key PointsAuthoritarian model of communication:

• The linear model of communication is often criticized for being authoritarian in nature, as it assumes that communication is a one-way process where the sender has complete control over the message and the receiver is a passive recipient who is expected to understand and accept the message without question or feedback.
• This model is often associated with a top-down approach to communication, where those in positions of power or authority are the senders of messages and those in subordinate positions are the receivers.
• The linear model of communication can be seen as authoritarian because it does not allow for feedback or negotiation between the sender and the receiver.
• In this model, the sender is seen as the authority figure who has the power to determine the content and direction of the message, while the receiver is seen as subordinate and passive.
• This model does not take into account the fact that communication is a two-way process, where both the sender and the receiver play an active role in creating and interpreting meaning.

Additional InformationLiberal model of communication:

• The liberal model of communication is a more interactive and participatory approach to communication that emphasizes individual freedoms and rights.
• It is based on the principles of liberalism, which values the free flow of information and the right to free expression.

Confessional model of communication:

• The confessional model of communication is a type of communication that emphasizes self-disclosure and personal expression.
• It is often associated with therapeutic or counseling settings, where individuals are encouraged to share their personal experiences and emotions in order to gain insight and understanding.

Participatory model of communication:

• The participatory model of communication is a type of communication that emphasizes the active participation of individuals and communities in the communication process.
• It is based on the idea that communication is a two-way process that involves both sending and receiving messages and that individuals and communities have the right to participate in the creation and dissemination of information.

Studying the practical use of signs and their impact on everyday life is called Pragmatics.

Key Points

Pragmatics:

• Pragmatics is a subfield of linguistics that studies the use of language in context.
• It is concerned with how people use language to communicate effectively in different situations and how language use is influenced by social and cultural factors.
• Unlike linguistics, which broadly studies language, its structure, and its use, pragmatics zeros in on the ways in which language is used in real-world situations and how people understand language in those contexts.
• This includes studying signs and their usage beyond their literal meanings, considering factors like the speaker's intent, the relationship between the speaker and the listener, the conventions of use in the relevant culture or community, and the specific situation in which communication takes place.

Confusion PointsThe relation between semantics and semiotics might seem straightforward: 

Semantics is the study of the meaning and reference of linguistic expressions, while semiotics is the general study of signs of all kinds and in all their aspects. Semiotics comprises semantics as a part.

Additional InformationLinguistics:

• Linguistics is the scientific study of language and its structure.
• It is a broad field that encompasses various subfields such as phonetics (the study of sounds), phonology (the study of sound patterns), morphology (the study of word structure), syntax (the study of sentence structure), semantics (the study of meaning), and pragmatics (the study of language use in context).

Syntactics:

• Syntactics is a subfield of linguistics that studies the structure of sentences and phrases in natural languages.
• It is concerned with the rules and principles that govern the arrangement of words and phrases to form grammatical and meaningful sentences.

Semiotics: 

• Semiotics is the study of signs and symbols, their use and interpretation, and their impact on communication and culture.
• It is a broad field that encompasses various disciplines such as linguistics, anthropology, philosophy, and communication studies, among others.
• Semiotics has applications in fields such as advertising, media, and design, and it seeks to understand how signs and symbols are used to create meaning and convey messages in different contexts.

Ineffective listening refers to a situation where a person is not fully engaged in the listening process or is not actively comprehending or interpreting the message being communicated. It can result from a variety of factors, including distractions, lack of interest or motivation, biases, preconceptions, or inadequate communication skills.

Important Points

There are several factors that can contribute to ineffective listening in a classroom. Some of these factors include: 

1. Distractions: A noisy or chaotic classroom environment can make it difficult to concentrate and focus on the teacher's message.
2. Lack of interest: Students who are not interested in the topic being discussed may not be fully engaged in the lesson and may miss important information.
3. Mental or physical fatigue: Students who are tired or stressed may have difficulty focusing on the teacher's message.
4. Lack of incentive: It is something something that is required but is absent or in short supply. It is the rewards and benefits used to motivate positive behaviors in a student.
5. Language barriers: Students who are not fluent in the language of instruction may struggle to understand the teacher's message.
6. Teacher's delivery: A teacher's delivery of a lesson can also impact a student's ability to listen effectively. For example, a teacher who speaks too quickly or uses complex language may make it difficult for students to follow along.
7. Personal issues: Personal issues or problems can also affect a student's ability to listen effectively in class. For example, a student who is dealing with a family crisis may have difficulty focusing on the lesson.
8. Attention Triggers: Attention triggers often rely on external stimuli such as loud noises, gestures, or visual cues to grab students' attention. While these triggers may initially capture students' focus, they can become less effective over time if they are overused or if students become desensitized to them. This can lead to a dependence on external cues rather than developing internal motivation for learning.

It is important for teachers to be aware of these factors and to take steps to create an environment that promotes effective listening and learning. 

Additional Information

• Inadequate preparation: Students who have not done the required reading or preparation for a lesson may struggle to follow along and understand the material being presented. Lack of listening preparation can hamper effective retention more than effective listening.
• Contextualisation of message: Contextualisation is putting language items into a meaningful and real context rather than being treated as isolated items of language for language manipulation practice only. It is helpful for effective listening.

The correct answer based on the given statements is both statements are true.

 Key Points

Statement I: In the earlier days of mass communication, content creators played an important role in the society.

• The first statement highlights the importance of content creators in the earlier days of mass communication.
• This is true as in the past, the access to the means of mass communication was limited to a few individuals or organizations who controlled the production and dissemination of information.
• These content creators had a significant role in shaping public opinion and influencing society through their messages.

Statement II: They represented and defined reality by authoring narratives to explain to the audience.

• The second statement suggests that content creators defined reality by authoring narratives to explain to the audience.
• This is also true as narratives, stories, and messages created by content creators have the power to shape the perception and understanding of the audience towards different issues, events, and phenomena.
• The narratives created by content creators can influence the way people perceive and interpret reality, and hence they play an important role in defining it.

Hence, Both Statement I and Statement II are true..

The mechanical model of mass communication was first introduced by Harold Lasswell in 1948. According to this model, communication is seen as a linear process where a message is sent from a sender to a receiver through a medium or channel. The message is then encoded by the sender and decoded by the receiver, with the assumption that the same meaning is understood by both parties.

Important PointsOne-way flow:

• A one-way flow of communication refers to a communication process where information is transmitted from one person or entity to another without any opportunity for feedback or response.
• This type of communication is also known as one-way communication or unidirectional communication.
• Examples of one-way communication include radio and television broadcasts, lectures, speeches, and some types of advertising.

From one-to-many:

• One-to-many communication is a type of communication in which one sender communicates with many receivers simultaneously.
• This type of communication is used in a variety of contexts, including broadcasting, public speaking, and mass email communications.

Examples of one-to-many communication include:

• A politician delivering a speech to a large crowd
• A teacher lecturing to a classroom full of students
• A news anchor broadcasting a story to a television audience
• A company sending a mass email to its customers
• A musician performing a concert for a live audience

Can be anonymous:

• Anonymous communication is possible through various means such as anonymous messaging apps, anonymous email services, and anonymous social media platforms.
• These tools allow users to communicate without revealing their identities, which can be useful in situations where privacy is a concern.
• However, it is important to note that anonymous communication can also be used for malicious purposes, such as cyberbullying or spreading false information, so it is important to use such tools responsibly.

Hence, the correct answer is B, C, D only.

Calculation:

Let's assume that B's age is x years.

Then, A's age is 4x years.

It is also given that in four years, A will be 40 years old.

Therefore, A's current age is 40 - 4 = 36 years.

We know that C's age was half the age of A four years ago. So, four

years ago, A's age was 36 - 4 = 32 years. At that time, C's age was

half of that, which is 16 years.

C's current age is 16 + 4 = 20 years.

According to the question,

4x = 36

⇒ x = 9.

B's current age is 9 years.

∴ The present age of B and C is 9 years and 20 years respectively.

So, family tree according to the given information is;

Hence, The man is the "father - in - law" of the the girl.

According to the given information, 

To find the distance between X and Z, we will use Pythagoras theorem,

(XZ)² = (XY)² + (YZ)² 

(XZ)² = (20)² + (20)²

⇒ 400 + 400

⇒ 800

XZ = √800

XZ = 20 √2 m

Hence, the distance between X and Z is 20√2 m.

Given:

The amount becomes ₹4500 at a 7% simple interest rate.

The amount becomes ₹3500 at a 5% simple interest rate.

Formula used:

Simple interest = \(\dfrac{P × R × T}{100}\)

P =Principal amount

R = Rate of  interest

T = Time duration

Amount = p + s.i

Calculation:

According to the question,

Amount = p + s.i

⇒ p + (p × 7 × t)/100 = 4500    ----(1)

⇒ p + (p × 5 × t)/100 = 3500    ----(2)

Subtract the eq. (2) from (1):

p + (p × 7 × t)/100 - p + (p × 5 × t)/100 = 4500 - 3500

⇒ 2pt/100 =1000 

⇒ pt = 50000    ----(3)

Putting the value of pt in equation 1:

 p + (50000 × 7)/100 = 4500

⇒ p = 4500 - 3500 = 1000

Now,

Amount = p + s.i

⇒  4500 = 1000 + s.i

⇒ s.i = 3500

Simple interest = \(\dfrac{P × R × T}{100}\)

⇒ 3500 = (1000 × 7 × T)/100

⇒ T = 50 years.

∴ The amount of money is 1000 and the time period is 50 years.

The logic followed here is;

Hence, the missing term is 1440.

If 'No metals are gases' is given as false, it means that there are some metals that are gases. Therefore, the statement that can be immediately inferred to be true is: D. Some metals are gases.

Key Points

• The given statement, "No metals are gases" is a categorical proposition in logic.
• It is a universal negative proposition, which means that it asserts that there is no overlap between the set of metals and the set of gases.
• In other words, it claims that all metals are non-gases and all gases are non-metals.
• However, we are told that this statement is false, which means that there is at least one metal that is a gas.

Therefore, the correct statement that can be immediately inferred to be true is "Some metals are gases."

Additional Information

• Option A, "All gases are metals" cannot be inferred to be true from the given information because it is a completely opposite statement to the given false statement.
• Option B, "All metals are gases" is also the opposite of the given false statement, and therefore it cannot be true if the given statement is false.
• Option C, "Some metals are not gases" is not necessarily true, even though it is opposite to the given false statement. It is possible that some metals are not gases, but we cannot infer this from the given information. We only know that at least one metal is a gas.

The statements that cannot both be false are B and C.

Important Points

• If statement B is false, it means that no metals are gases, which makes statement D true.
• But if statement D is true, then statement C must be false, which contradicts our assumption that statement B is false.
• Similarly, if statement C is false, it means that all metals are gases, which makes statement A true.
• But if statement A is true, then statement B must be false, which contradicts our assumption that statement C is false.

Therefore, the only possible combination of true statements is B and C.

"The last time I stretched my arms first and my legs second, I won my race, So that stretching sequence must have increased my speed." The Post hoc informal fallacy is committed in the above statement.

Key PointsPost hoc:

• The informal fallacy committed in the above statement is post hoc ergo propter hoc, which means "after this, therefore because of this."
• The fallacy assumes that because one event happened before another, it must have caused the second event.
• In this case, the person assumes that the stretching sequence caused them to win the race because they did the stretching sequence before the race and then won.
• However, there could be other factors that contributed to their win, such as their overall fitness, training, or even luck, rather than the stretching sequence alone.

Therefore, this argument is flawed, and it is essential to consider other possible explanations before jumping to conclusions.

Additional InformationFalse alternative:

• A false alternative fallacy occurs when only two options are presented as the only possible choices, when in reality there may be other options available.
• This fallacy is also known as a false dichotomy or black and white fallacy.
• For example, a politician might say, "You are either with us or against us," implying that there are only two options: support their policy or be against it. This argument ignores the possibility that someone may have a different opinion or propose an alternative solution.

Hasty generalization:

• Hasty generalization, also known as "jumping to conclusions," is a logical fallacy in which a conclusion is drawn based on insufficient or limited evidence.
• For example, if someone assumes that all dogs are aggressive based on one bad experience with a dog, that would be a hasty generalization. Similarly, if someone assumes that all politicians are corrupt because of a few cases of political corruption, that would also be a hasty generalization.

Slippery slope:

• The slippery slope is a logical fallacy that suggests that if a particular action is allowed, it will inevitably lead to a series of increasingly negative consequences or actions.
• For example, a common slippery slope argument is that if we legalize marijuana, it will inevitably lead to the legalization of harder drugs like heroin and cocaine. However, this argument ignores the fact that each drug has unique properties and effects, and the legalization of one does not necessarily lead to the legalization of others.

According to Nyāya (classical Indian school of logic) 'Sound is eternal because it is produced' is Viruddha argument.

Key PointsViruddha:

• In Ayurveda, one of the key principles is "Viruddha", which refers to incompatible or contradictory substances, activities, or conditions.
• The term "Viruddha" means "opposite" or "contradictory."
• A "Viruddha argument" refers to an argument that is self-contradictory or contradictory to established principles.
• In Ayurveda, a Viruddha argument could be an argument that contradicts the principles of the treatment or the diagnosis of a disease.
• For example, if a person is suffering from a cold, and a practitioner suggests drinking cold water to cure it, it would be a Viruddha argument because cold water would aggravate the cold symptoms.

Additional InformationSãdhāraṇa:

• "Sādhāraṇa" is a Sanskrit term that can be translated as "general" or "common."
• In Hindu philosophy, it is used to refer to that which is universal or applicable to all.
• For example, sādhāraṇa dharma refers to the universal principles of righteousness that apply to all people regardless of their caste or social status.

Svarūpāsiddha:

• Svarūpāsiddha is a concept in the philosophy of Advaita Vedanta, a school of Hindu philosophy.
• It refers to the innate nature of the self, which is said to be already perfect and complete, and not in need of any external validation or transformation.

Mistake Points Sãdhāraṇa:

In Nyaya philosophy, the term "sadhāraṇa" refers to the concept of generality or universal property. It is an important concept used in logical and epistemological analysis.

According to Nyaya philosophy, sadhāraṇa represents the common or shared attribute that is present in multiple individual objects or entities. It refers to the universal aspect or general characteristic that is shared by a group of particular objects or instances.

Svarūpāsiddha:

In Nyaya philosophy, the term "svarūpāsiddha" refers to self-established or self-evident knowledge. It is a type of knowledge that is directly perceived or apprehended without the need for any further proof or justification.

The statement "No metals are gases" can be rewritten in a logical form as "For all x, if x is a metal, then x is not a gas."

Key Points

• "No gases are metals," has the same form as the original statement, but with the subject and predicate reversed.
• This is a logically equivalent statement to the original statement, as it is also saying that there is no overlap between the set of metals and the set of gases.

Additional Information

• Option 1, "All non-metals are gases," is not logically equivalent to the original statement, as it is a statement about all non-metals, not just the relationship between metals and gases.
• Option 3, "No metals are non-gases," is also not logically equivalent to the original statement, as it allows for the possibility that metals may be gases.
• Option 4, "All non-gases are non-metals," is not logically equivalent to the original statement, as it is a statement about all non-gases, not just the relationship between metals and gases.

Therefore, "No gases are metals," is the logically equivalent statement to the original statement "No metals are gases."

The correct order of the stages when an email is sent and received is:

• C. The sender composes his message and activates the send command.
• E. Message is sent to sender's ISP mail server and this server examines the address associated with the message.
• A. Sender's ISP mail server decides how to route the message, and the message travels over the Internet and arrives at recipient's ISP mail server.
• D. Message held in recipient's electronic mail box and recipient logs on to read his messages.
• B. Message retrieved and sent to the recipient's computer to be opened and read.

Therefore, the correct order is: C-E-A-D-B. 

Key Points The stages involved when an email is sent and received can be summarized as follows:

1. Composing: The sender composes the email message in their email client or webmail interface, addressing it to one or more recipients.
2. Sending: Once the sender is satisfied with the message, they click on the "Send" button, and the email is transmitted to the sender's outgoing mail server (SMTP server).
3. Routing: The outgoing mail server routes the email to the recipient's incoming mail server (also an SMTP server), using the recipient's email address.
4. Delivery: The recipient's incoming mail server receives the email and places it in the recipient's mailbox on the server.
5. Viewing: The recipient opens and reads the email message in their email client or webmail interface.
6. Retrieval: The recipient uses their email client or webmail interface to retrieve the email from the server, either by accessing the server directly or by using a protocol like IMAP or POP to download the email to their device.

The primary storage devices are the ones that hold data that is currently being accessed by the CPU. RAM and ROM are primary storage devices.

Important Points

RAM (Random Access Memory):

• RAM (Random Access Memory) is a type of computer memory that allows information to be stored and retrieved quickly by a computer's processor.
• RAM is considered a volatile memory, meaning that it can only store data while the computer is powered on, and it loses all data once the power is turned off.

ROM (Read-Only Memory):

• ROM (Read-Only Memory), is a type of non-volatile memory that stores data permanently and cannot be modified by the CPU.
• It is also considered as a type of primary storage, but its use is limited to storing the computer's BIOS (Basic Input/Output System) and firmware.

Additional Information

• A removable hard disk drive, is a type of secondary storage device, as it holds data that is not immediately required by the CPU.
• DVD/CD, is also a type of secondary storage device, as it holds data that is not immediately required by the CPU.

The correct answer is

Important PointsStatement I: (4A2F)16 = (18991)10

• 4A2F from hexadecimal to decimal is 18991.

To convert the hexadecimal number 4A2F to decimal, follow these two steps:

Start from one's place in 4A2F:

• Multiply ones place with 16^0, tens place with 16^1, hundreds place with 16^2, and so on from right to left
• Add all the products we got from step 1 to get the decimal equivalent of 4A2F.
• Using the above steps, here is the work involved in the solution for converting 4A2F to a decimal number (Don't forget that we start from ones place to so on...)

Decimal equivalent of "F" = (F) 15 × 16^0 = 15

Decimal equivalent of "2" = 2 × 16^1 = 32

Decimal equivalent of "A" = (A) 10 × 16^2 = 2560

Decimal equivalent of "4" = 4 × 16^3 = 16384

Decimal equivalent of "4A2F" = 16384+2560+32+15

4A2F = 18991

Here is the final answer, The hexadecimal number 4A2F converted to decimal is therefore equal to 18991

Hence, statement I is true.

Statement II: (6940)10 = (1B1C)16 is true because:

(1B1C)16 = (1 × 16^3) + (11 × 16^2) + (1 × 16^1) + (12 × 16^0)

= (1 × 4096) + (11 × 256) + (1 × 16) + (12 × 1)

= 4096 + 2816 + 16 + 12

= 6940

Therefore, (1B1C)16 = (6940)10 is correct.

• Article 48A of the Indian Constitution states that "The State shall endeavour to protect and improve the environment and to safeguard the forests and wildlife of the country."
• This article emphasizes the need to protect and improve the environment and to safeguard forests and wildlife.

Hence, statement I is not correct.

Statement II: Article 51: Directive Principles of state policy are to ensure protection and improvement of the natural Environment.

• Article 51 of the Indian Constitution outlines Directive Principles of State Policy, which encourage the state to promote international peace, respect for international law, and the principles of the United Nations Charter.
• The article states that the state shall strive to promote international peace and security, maintain just and honorable relations between nations, respect international law and treaty obligations, and encourage settlement of international disputes through peaceful means.

Hence, statement II is also incorrect.

Therefore, both the statements are incorrect.

The correct answer is Statement I is false but Statement II is true.

Important PointsStatement I: Distance education has replaced the formal education in India

• Distance education has not replaced formal education in India.
• Although the popularity and acceptance of distance education have increased in recent years, it is still considered as an alternative mode of education and is not a complete replacement for formal education.
• Formal education still remains the primary mode of education in India, and most students still prefer to attend regular classes in colleges and universities.

Statement I is not correct.

Statement II: Distance education reduces the cost of education.

• It is true that distance education can reduce the cost of education in some cases.
• The cost of distance education can vary depending on the course, institution, and mode of delivery.

Colloidal and dissolved organic matter are removed through secondary waste water treatment process.

Key PointsColloidal and dissolved organic matter:

• Colloidal and dissolved organic matter are small particles and dissolved substances, respectively, that are not effectively removed during primary wastewater treatment processes such as sedimentation or screening.
• However, secondary treatment processes, such as biological treatment or chemical treatment, can effectively remove colloidal and dissolved organic matter from wastewater.
• During biological treatment, microorganisms such as bacteria, fungi, and algae consume and break down organic matter, including colloidal and dissolved organic matter.
• In chemical treatment, coagulants and flocculants are added to wastewater to bind to colloidal and dissolved organic matter and form larger particles that can be more easily removed through sedimentation or filtration.

Therefore, it is correct to say that colloidal and dissolved organic matter are typically removed during secondary wastewater treatment processes.

The correct answer is Statement I is incorrect but Statement II is correct.

Key Points

• Refer to the line: In 1882 the Punjab University was established by a Special Act of Incorporation and in 1887 another Special Act of Incorporation established the fifth Indian university at Allahabad.
• Thus, we can conclude that Allahabad University and Punjab University were not established at the same time. Thus, Statement I is incorrect.
• Refer to the lines: The general framework of these two Special Acts of Incorporation was similar to the Acts of 1857 though power was given to the Senates of the Punjab and the Allahabad Universities "to appoint or provide for the appointment of Professor and Lecturers"- a privilege which was denied by the Acts of Incorporation to the first three universities at Calcutta, Bombay and Madras in 1857. 
• ​Thus, Statement II is correct as Bombay University and Madras University were established at the same time

The correct answer is Both Statement I and Statement II are incorrect.

Key Points

• Statement I is incorrect. The Acts of Incorporation for each university were not exactly the same, although they had a similar framework. While the Acts of Incorporation for the universities established in India shared a general framework, there were differences in the specific provisions granted to each university.
• ​Statement II is incorrect. The Acts of Incorporation for the universities of Calcutta, Bombay, and Madras did not grant them the power to appoint professors and lecturers, while the Acts for Punjab University and Allahabad University did. Allahabad University was the fifth Indian university to be established and was granted the power to appoint professors and lecturers in 1887.

The correct answer is C, D and E only.

Key Points

• The passage states that the first three universities established in India were Calcutta, Bombay, and Madras.
• These universities were founded in 1857 and were intended to be examining universities only, modeled after the University of London. As a result, the Acts of Incorporation for these universities did not provide for the appointment of professors and lecturers, unlike the later Punjab University and Allahabad University which were established in 1882 and 1887 respectively.
• Thus, we can conclude that Calcutta, Bombay, and Madras are the first three universities established in India.

The correct answer is (A) is not correct but (R) is correct.

Key Points

• From the passage, we can understand that the Acts of Incorporation for the first three universities at Calcutta, Bombay, and Madras in 1857 did not grant them the power to appoint Professors and Lecturers.
• ​Thus, we can conclude that when Calcutta University was established, it was not granted the power to appoint Professors and Lecturers making statement (A) incorrect.
• Refer to the lines: Thereby it ignored an important suggestion of the Education Despatch of 1854 which suggested possible institution of "professorships for the purpose of the delivery of lectures in various branches of learning for the acquisition of which, at any rate in an advanced degree, facilities do not now exist in other institutions in India."
• ​Thus, we can infer that Education Despatch of 1854 suggested the possible institution that could appoint Professors i.e. (R) is correct.
• Thus, option 4 is the correct answer.

The correct answer is Statement I is correct but Statement II is incorrect.

Key Points

• Refer to the lines: a privilege which was denied by the Acts of Incorporation to the first three universities at Calcutta, Bombay and Madras in 1857. The first three universities were deliberately intended to be examining universities only, in the same manner and on the same model as the then University of London.
• ​Thus, Statement I is correct. The University of London was established in 1836 as an examining university, which means that it did not offer any teaching or instruction, but only conducted examinations for its affiliated colleges.
• Refer to the lines: *The first three universities (*Calcutta, Bombay and Madras) were deliberately intended to be examining universities only, in the same manner and on the same model as the then University of London. Thereby it ignored an important suggestion of the Education Despatch of 1854 which suggested possible institution of "professorships for the purpose of the delivery of lectures in various branches of learning for the acquisition of which, at any rate in an advanced degree, facilities do not now exist in other institutions in India."
• ​It was only later when the Punjab University and the Allahabad University were established that the power to appoint professors and lecturers was given to the Senates. Therefore, Statement II is incorrect.

Given:

Indonesia(Scientific) = 73%

Indonesia(Conventional) = 27%

Indonesia = 10% distribution out of 50 lakh tonnes

Calculation:

Total = 50 lakh tonnes

10% = 0.1 × 50,00,000 = 5 lakh tonnes

⇒  Difference in scientific and conventional in Indonesia = 73 - 27 = 46%

Now, 100% = 5 lakh tonnes

⇒  46% = 0.46 × 5,00,000 = 2,30,000 tonnes

∴ The difference between the production of wheat by the Scientific Method and the Conventional Method in Indonesia is 2.3 lakh tonnes.

Concept used: 

Average = Sum of observation / Number of observation

Calculation:

⇒ Sum of observation = \(\dfrac{50,00,000}{100 × 100}\) × [(18 × 32) + (22 × 70) + (20 × 78) + (13 × 60) + (10 × 73) + (9 × 66) + (8 × 20)]

= 500 × 5940= 29.7 lakhs

⇒ Average = \(\dfrac{2970000}{7}\) = 4.24 lakh tonnes.

∴The approximate average production of wheat (in lakh tonnes) by the Scientific Method for all the seven countries is 4.24

Given:

Wheat by Conventional Method in Pakistan = 34%

Scientific Method in Japan = 78%

Calculation:

⇒ Wheat by Conventional Method in Pakistan = 0.09 × 0.34 × 50,00,000 = 1.53 lakh tonnes

⇒ Wheat by Scientific Method in Japan = 0.2 × 0.78 × 50,00,000 = 7.8 lakh tonnes

⇒ Required Ratio = 1.53 : 7.8 = 51 : 260

∴   The ratio of the production of wheat by Conventional Method in Pakistan to that by the Scientific Method in Japan is 51 : 260.

Given:

Production of wheat in Srilanka by the Conventional Method = 13% of 40% of 50 lakh tonnes

Production of wheat in India by the Scientific Method = 18% of 32% of 50 lakh tonnes

Calculation:

Production of wheat in Srilanka by the Conventional Method = 13% of 40% of 50 lakh tonnes

⇒ 0.13 × 0.4 × 50,00,000 = 2.6 lakh tonnes

Production of wheat in India by the Scientific Method = 18% of 32% of 50 lakh tonnes

⇒ 0.18 × 0.32 × 50,00,000 = 2.88 lakh tonnes

⇒ Required times = \(\dfrac{260}{288}\) = 0.9 times

∴  Production of wheat in Srilanka by the Conventional Method is approximately 0.9 times the production of wheat in India by the Scientific Method.

Given:

Production of wheat in Pakistan by the Conventional Method = 9% of 34% of 50 lakh tonnes

Production of wheat in India by the Scientific Method = 18% of 32% of 50 lakh tonnes

Calculation:

Production of wheat in Pakistan by the Conventional Method = 9% of 34% of 50 lakh tonnes

⇒ 0.09 × 0.34 × 50,00,000 = 1.53 lakh tonnes

Production of wheat in India by the Scientific Method = 18% of 32% of 50 lakh tonnes

⇒ 0.18 × 0.32 × 50,00,000 = 2.88 lakh tonnes

⇒ Required % = \(\dfrac{288 - 153}{153}\) × 100 = 88.24%

∴ Production of wheat in India by the Scientific Method is approximately 88.24 % more than the production of wheat in Pakistan by the Conventional Method.
