UGC NET Paper 1: Held on 9th July 2022 Shift 1 (Previous Year Paper)

The correct answer is  (B), (C), and (D) only.

Important Points

• (B) Synthesis and organization of the old and new experiences resulting in a novel pattern
• Accurately describe a key aspect of the learning process,
• As it involves creating new connections and patterns in the brain based on previous experiences and new information.
• (C) Carrying out activities that leave a permanent effect on the learner
• Also reflects an important aspect of the learning process, as repeated exposure and
• Engagement with information can lead to long-term changes in knowledge and behavior.
• (D) Learning means acquisition, retention, and modification of experience
• Is a broad and accurate definition of the learning process, as it encompasses the various steps involved in acquiring and retaining new information,
• As well as making changes to existing knowledge and behavior based on new experiences.

 

Additional Information

(A) Remembering the information and reproducing it in an examination only partially reflects the learning process,

• as while memorization is a component of learning,
• it is not the only aspect, and true learning involves a deeper understanding and synthesis of information.

(E) Preparing only for scoring good marks is not a correct

• representation of the learning process, as while achieving good grades may be a motivation for learning,
• it is not the only reason or outcome of the learning process, and true learning involves a deeper engagement and understanding of the information being studied

Key Points

Learning:

• Learning is the process of acquiring knowledge, skills, values, beliefs, and habits through study, experience, or being taught.
• It is a lifelong process in various settings, including formal education, on-the-job training, and everyday life experiences
• Learning can be intentional or unintentional, conscious or unconscious, resulting in a permanent change in behavior or understanding.
• Learning can involve acquiring new information, developing new skills, or refining existing knowledge and abilities.

The correct answer is  (B), (C), (D) only.

Key Points 

Explanation: Remote data collection procedures refer to methods of collecting data from individuals or groups who are not physically present in a common location.

• (B) Pop-ups: These are forms or ads that appear over the content of websites. In the context of data collection, they could be used for various purposes like capturing email addresses, understanding user preferences, collecting customer feedback, and more. As these interactions happen online, without face-to-face contact, pop-ups are considered a remote data collection process.
• (C) Database E-mail: In the context of data collection, this could refer to strategies where information is gathered through emails. This can range from sending out surveys via email to simply analyzing user responses from their emails. As this collects data remotely without physical interactions, it is considered a remote data collection method.
• (D) Instant Messaging: This could refer to several types of synchronous written online communication like Slack, WhatsApp, or Facebook Messenger. These can be used for conducting interviews, group discussions, or surveys where the participants can respond in real time but without any face-to-face interaction. This makes instant messaging a remote data collection method.

The other options, (A) Third party interview, and (E) Panel discussions are not typically considered remote data collection procedures as they require a physical presence in a common location.

(A) Third-party interview: This is a research method where someone other than the primary researcher conducts the interview.

• This could be brought into the remote data collection category if the interview is carried out remotely via video conferencing or phone interviews. However, it can also be conducted face-to-face, which precludes it from being purely a remote data collection method.
• Therefore, whether it belongs to remote data collection methods or not depends on the specific context in which it's conducted.

 

(E) Panel discussions: This refers to a discussion format where a group of people gathers to discuss a topic, often in front of an audience.

• This can be conducted both face-to-face or remotely (like webinars or video conferences). However, it's not typically, from a traditional standpoint, considered remote as they often occur in person.
• Because of this, it typically wouldn't fall into the category of a remote data collection method unless it is specified that it is conducted remotely.

 

Additional Information

There are several methods of data collection, which can be broadly categorized into two categories: primary data collection and secondary data collection.

1. Primary Data Collection:

• Surveys: Surveys can be conducted through various mediums such as mail, phone, online, or in-person interviews. Surveys are a popular method of primary data collection as they allow researchers to gather large amounts of data from a diverse group of people.
• Observations: Observational research involves observing and recording data systematically. It can be conducted in a natural setting or a controlled laboratory environment.
• Experiments: Experiments are designed to test causal relationships between variables. In an experiment, researchers manipulate one or more independent variables and observe the effect on the dependent variable.
• Focus groups: Focus groups are moderated group discussions designed to gather information about a specific topic. They are often used to collect qualitative data and to gain a deeper understanding of attitudes and behaviors.

2. Secondary Data Collection:

• Literature review: This method involves collecting data from existing sources such as journal articles, books, and reports. The data collected from this method is often used to build a theoretical foundation or to provide background information.
• Database: A database is a collection of data organized in a specific way. Data can be collected from databases maintained by government agencies, private organizations, or individuals.
• Archives: Archives refer to collections of historical records and documents that can be used to gather data. These records can be stored in physical archives or in digital archives.

The correct answer is "Encoding".

Important Points 

• Encoding
• refers to the process of transforming ideas, thoughts, and messages into verbal and non-verbal signs and symbols that can be transmitted from one person to another.
• This process involves translating abstract concepts and ideas into a form that can be communicated and understood by others, often through the use of language, gestures, or visual symbols.
• Decoding
• on the other hand, refers to the process of interpreting and making sense of encoded messages and information.
• This involves taking the signs and symbols that have been encoded by someone else and interpreting them in a way that makes sense to the person receiving the message.
• Channelization
• refers to the means by which a message is transmitted, such as through speaking, writing, or body language.
• Controlled communication
• Refers to communication that is managed or regulated in some way, often through the use of rules or guidelines.
• This type of communication is often used in formal settings, such as in the workplace, where clear and consistent messages are important.
• A linear model of communication

Key Points

• Communication is a complex process, and it is difficult to determine where or with whom a communication encounter starts and ends.
• 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 correct option is  (B), (A), (D), (C), (E)"

Important Points

This sequence of elements represents Aristotle's model of communication, also known as the "Aristotelian model" or the "Rhetorical Triangle." According to Aristotle, effective communication involves the following five elements:

1. Speaker: The person responsible for delivering the message
2. Speech: The message itself, including the words, tone, and delivery style used by the speaker
3. Occasion: The context in which the message is being delivered, including the purpose, audience, and setting
4. Audience: The individuals or groups to whom the message is directed
5. Effect: The impact that the message has on the audience, including the attitudes, beliefs, and behaviors that it elicits

In this model, the speaker and speech are the central elements of communication, with the occasion and audience serving as the context in which the message is delivered, and the effect representing the outcome of the communication process. According to Aristotle, effective communication requires the speaker to carefully consider all of these elements and tailor their message to the particular audience and occasion in order to maximize its impact.

Additional Information

The Aristotle model of communication is a linear model with a focus on public speaking. The Aristotle model of communication was developed by the Greek philosopher and orator Aristotle, who proposed the linear model to demonstrate the importance of the speaker and their audience during communication.

It comprises three key elements:

• Ethos (the speaker’s degree of credibility or authority),
• Pathos (the ability of the speaker to form an emotional bond with the audience),
• Logos (the literal meaning of the word logos is logic).
• "Rhetorical Triangle.

The pattern followed here is,

even numbers starting from 6 are added to the series consecutively

16 + 6 = 22

22 + 8 = 30

30 + 10 = 40 ≠ 45

40 + 12 = 52

52 + 14 = 66

Hence, 45 is an incorrect number in the series.

The logic follows here is:

• EARTH be written as QPMZS

Similarly,

• HEART will be written as:

​

Hence, the correct answer is "SQPMZ".

The correct answer is (B), (C) and (D) only.**

Important Points 

The classical square of opposition is a diagram that illustrates the relationships between four basic types of categorical propositions: A (All S is P), E (No S is P), I (Some S is P), and O (Some S is not P).

The classical square of opposition consists of four standard categorical propositions:

• Universal Affirmative (A): All S is P.
• Universal Negative (E): No S is P.
• Particular Affirmative (I): Some S is P.
• Particular Negative (O): Some S is not P.

When "No S is P" is given as false, it means that at least some S is P, which means that "Some S is P" is true. Therefore, option (D) "Some S is P is true" is a valid inference.

Key Points

(A) "Some S is not P" is true:

• We cannot infer this from the information given because the falsity of "No S is P" does not necessarily mean that "Some S is not P" is true.
• It only means that there is at least some overlap between S and P.

(B) "All S is P" is undetermined:

• This is a valid inference.
• The falsity of "No S is P" doesn't provide information about whether "All S is P" is true or false.
• It leaves this proposition undetermined.

(C) "Some S is not P" is undetermined:

• This is also a valid inference for the same reason as option (B).

(E) "Some S is not P" is false:

• We cannot conclude this from the given information.
• The falsity of "No S is P" means there is some overlap between S and P, but it doesn't tell us if "Some S is not P" is false.

So, the correct answer is (B), (C), and (D), as these can be immediately inferred from the given information.

The correct option is The Appeal to Emotion 

Important Points 

• The argument "Smooth Sailing is all that's there to LIFE with ABC Insurance Policy" is committing the fallacy of Appeal to Emotion.
• An Appeal to Emotion is a type of informal fallacy that occurs when an argument appeals to the emotions of the reader or listener, rather than to reason or evidence.
• In this argument, the speaker is using the phrase "Smooth Sailing" to evoke positive emotions and create a positive image of life with ABC Insurance Policy.
• The argument is attempting to influence the reader or listener by appealing to their emotions, rather than by providing evidence or logical reasoning to support the conclusion.
• Therefore, the argument is committing the fallacy of Appeal to Emotion by attempting to persuade the reader or listener through emotional manipulation, rather than through logical argumentation.
• This type of fallacy can lead to false or misleading conclusions and should be avoided in critical thinking and argumentation.​

Additional Information 

• Appeal to Emotion:
• An Appeal to Emotion is a type of informal fallacy that occurs when an argument appeals to the emotions of the reader or listener, rather than to reason or evidence.
• This type of fallacy is often used to manipulate the emotions of the reader or listener in order to influence their opinion or decision.
• Examples of emotional appeals include using fear, anger, guilt, or joy to sway the reader or listener.
• Appeal to Pity:
• The Appeal to Pity is a type of informal fallacy that occurs when an argument appeals to the sympathy or compassion of the reader or listener in order to influence their opinion or decision.
• This type of fallacy is often used to evoke feelings of pity or compassion for a particular individual or group in order to persuade the reader or listener to accept a conclusion.
• Appeal to Force:
• The Appeal to Force is a type of informal fallacy that occurs when an argument threatens the reader or listener with harm, violence, or punishment in order to influence their opinion or decision.
• This type of fallacy is often used to intimidate or coerce the reader or listener into accepting a conclusion and is considered unethical and unacceptable in most forms of argumentation.
• Irrelevant

Conclusion:

• The Irrelevant Conclusion, also known as Ignoratio Elenchi or "missing the point," is a type of informal fallacy that occurs when an argument fails to address the main issue or question at hand.
• This type of fallacy is often used to distract the reader or listener from the main issue by introducing irrelevant or unrelated information, or by making an emotional appeal.
• The conclusion of the argument is not logically related to the premises and thus fails to address the main question or issue.

The correct answer is  Postulation (Arthapatti).

Key Points

• Arthapatti, also known as postulation, is one of the six means of knowledge in Indian philosophy.
• It involves positing the existence of something to make a unit of cognition self-complete.
• In other words, it involves assuming the existence of something in order to make a certain understanding or belief logically consistent.

For example, if someone says that they saw a person walking into a room, but there is no one there now, we can postulate that the person must have left the room. This postulation is not based on direct perception or inference but is necessary to make the statement logically consistent.

• Arthapatti is considered a valid means of knowledge in some Indian philosophical schools, such as the Nyaya school, and is used to support certain beliefs that cannot be established through direct perception, inference, or any other means of knowledge.
• It should be noted that the use of postulation as a means of knowledge is controversial, and not all philosophical schools accept it as valid. Nevertheless, it remains an important concept in Indian philosophy and continues to be studied and debated by scholars.

Important Points

Postulation, or Arthapatti, is a means of knowledge in Indian philosophy that involves positing the existence of something in order to make a unit of cognition self-complete. It is used to support certain beliefs that cannot be established through direct perception, inference, or any other means of knowledge.

There are two main types of postulation:

1. Pratijñā-arthāpatti: This type of postulation involves assuming the existence of something in order to establish the truth of a particular proposition. For example, if someone says that they saw a person walking into a room, but there is no one there now, we can postulate that the person must have left the room in order to make the statement logically consistent.
2. Hetu-arthāpatti: This type of postulation involves assuming the existence of something in order to resolve a logical contradiction. For example, if we observe that someone is both old and young at the same time, we can postulate that the person is both old and young in different ways (e.g., old in terms of experience and young in terms of appearance) in order to resolve the contradiction

The correct answer is  Fibre optic cable carries data in pulses of light and is not prone to interference.

Important Points

• Optical fibers are transparent fibers and act as a light pipe to transmit light between their two ends. They are made up of silicon dioxide.
• The total internal reflection occurs when the angle of incidence is greater than the critical angle.
• In optical fiber glasses of a high and lower index are assembled in a precise order.
• The light comes in from one end of the fiber and after thousands of successive internal reflections, the light reaches the opposite end of the fiber with almost zero loss.
• A fiber optic cable is a type of cable that is used for data communication. It uses light to transmit information from one point to another. The data is carried in the form of pulses of light, which travel along the length of the cable.

Key PointsFiber optic cable:

• Carries data in the form of light pulses
• High bandwidth capacity
• Immune to interference (electromagnetic, radio frequency)
• High signal speed
• Low signal attenuation
• Thin and flexible
• Safe from tapping/eavesdropping
• Suitable for long-distance transmission
• Expensive compared to copper cables.

Percentage of the population of state 'D' below poverty line = 19%

So, the number of people in state 'D' below poverty line = 19% of 8 million = 1.52 million.

The proportion of males and females in state 'D' below poverty line is 3∶2.

So, the number of males below poverty line in state 'D'

= 3/(3+2) x 1.52 million = 0.912 million.

The number of females below poverty line in state 'D'

= 2/(3+2) x 1.52 million = 0.608 million.

The proportion of males and females in state 'D' above poverty line is 5∶3.

So, the number of males above poverty line in state 'D'

= 5/(5+3) x (8-1.52) million = 4.05 million.

The number of females above poverty line in state 'D'

= 3/(5+3) x (8-1.52) million = 2.43 million.

Therefore, the number of females above poverty line in state ‘D’ is 2.43 million.

Calculation:

Percentage of population above poverty line in state C = 100% - 24% = 76%

The ration of male and female for state C who are above poverty line = 2 : 3

Let the total population of state C = x

The fraction of male above poverty line is 2/5 and also male population above poverty line for state ‘C’ is 1.9 million.

\(x \times \frac{76}{100} \times \frac{2}{5} \) 

x = 6.25 million

Calculation:

Percentage of population below the poverty line for state A= 35%

Also, the ratio of males and females below the poverty line for state A = 5:6

Fraction of females = 6/11

Also, the female population below the poverty line for state A is 21 million.

Let the total population of state A be x

\(⇒ x \times \frac{35}{100} \times \frac{6}{11} = 2.1\)

⇒x=11 million

Thus, the total population of state A is 11 million,

Now, the percentage of population above the poverty line for state A

⇒100% - 35% = 65%

Number of the population above the poverty line for state A

⇒  65% of 11 million = 7.15 million

Also, the ratio of males and females above the poverty line for state A = 6:7

Fraction of males = 6/13

Number of males above the poverty line for state A

⇒ (6/13) x 7.15=3.3 million

Hence, there are 3.3 million males above the poverty line in state A.

Calculation:

For State Q, Male population below poverty line = 2.4 million.

Let the female population below poverty line be x million.

Then, 3 : 5 = 2.4 : x

⇒  x = 5 x  2.4/3  = 4.

Therefore Total population below poverty line = (2.4 + 4) = 6.4 million.

If Nq be the total population of State Q, then,25% of Nq = 6.4 million

⇒  Nq = (6.4 x 100)/25 million = 25.6 million.

For State T, Male population below poverty line = 6 million.

Let the female population below poverty line be y million.

Then, 5 : 3 = 6 : y => y = 3 x 6/5 = 3.6.

Therefore Total population below poverty line = (6 + 3.6) = 9.6 million.

If Nt be the total population of State T, then,15% of Nt = 9.6 million

⇒  Nt = (9.6 x 100)/15 million = 64 million.

Thus, Required ratio = Nq/Nt = 25.6/64 = 0.4 = 2/5.

Calculation:

Total population below poverty line in state C = (24/100) x 5 million = 1.2 million

Total population below poverty line in state D = (19/100) x 7 million = 1.33 million

The difference in the population below poverty line in these two states will be:

1.33 million - 1.2 million = 0.13 million

Therefore, the difference in the population below poverty line in states C and D is 0.13 million.

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

Important Points

• Statement I: Assessment drives learning.
• This statement is correct, as assessment is a crucial component of the learning process.
• Through assessment, students receive feedback on their understanding and performance,
• which can help guide their learning and motivate them to improve. When assessments are used formatively,
• they provide valuable information that students can use to adjust their approach and make progress toward their learning goals.
• Statement II: No feedback is required to be given in formative assessments.
• This statement is incorrect, as feedback is a crucial component of formative assessment.
• Formative assessment is designed to support student learning by providing ongoing feedback throughout the learning process.
• Feedback can take many forms, such as comments, grades, or suggestions for improvement, and it helps students understand their strengths and weaknesses and adjust their approach to learning accordingly.
• Without feedback, formative assessment loses much of its value as a tool for supporting student learning
• It provides feedback on the performance of the student and helps in determining the areas of improvement.
• It is process-oriented which diagnoses the areas of improvement for the student

Key Points

Assessment is a process of collecting, receiving, and using data for the purpose of improvement in the learning process.

• Assessment is a systematic way of collecting information to make a judgment about student learning.
• It is integral to the teaching-learning process which helps in facilitating student learning and improving instruction.
• Assessment does more than just measure learning. There are two main types of assessments which include 'summative' and 'formative' assessments.​
• Formative assessment is an in-process evaluation of student learning i.e. administered multiple times during a unit, or course.
• Summative Assessment is used to evaluate student learning at the end of a specific instructional period

The answer is  (A) and (C) only.

Key Points 

T-test is a statistical method used to determine if there is a significant difference between the means of two groups

 T-Test: 

• The t-test tells you how significant the differences between groups are; In other words it lets you know if those differences (measured in means) could have happened by chance.
• The t-test is one of many tests used for the purpose of hypothesis testing in statistics.
• There are two types of statistical inference: parametric and nonparametric methods.
• Parametric methods refer to a statistical technique in which one defines the probability distribution of probability variables and makes inferences about the parameters of the distribution.
• In cases in which the probability distribution cannot be defined, nonparametric methods are employed.
• T-tests are a type of parametric method; they can be used when the samples satisfy the conditions of normality, equal variance, and independence.
• It is a two-tailed test

Important Points

• (A) MS Excel: Microsoft Excel provides basic statistical analysis tools, including t-tests. This means that users can perform t-tests using Excel's built-in functions and formulas.
• (C) SPSS: SPSS (Statistical Package for the Social Sciences) is a software package that provides advanced statistical analysis tools, including t-tests. This means that users can perform t-tests using SPSS's advanced features and functions.

Both MS Excel and SPSS can be utilized to perform t-tests, which makes options 3) (A) and (C) only the correct answer.

Key Points 

Here is a table explaining the use and definition of the software programs mentioned:

The correct answer is  A - I, B - III, C - IV, D - II.

Important Points

• Cohort analysis (A) is a study of a specific population as it undergoes change over time (I)
• Cultivation analysis (B) is the analysis of perceptions of the social world (III)
• Factor analysis (C) is a multivariate statistical test used for data reduction (IV).
• Canonical analysis (D) is a simultaneous analysis of two or more data tables (II).

Key Points

Here is a table that summarizes the methods, ways, and uses of the types of research listed in the question:

Given:

10 chairs and 5 tables were purchased for Rs. 17,500.

Calculation:

Let the average cost of a table be x. 

10 chairs cost = 10 x 1000 = Rs. 10,000

5 tables cost = 5x

Total cost = 10,000 + 5x = 17,500

Subtracting 10,000 from both sides, we get:

5x = 7,500

x = 1,500

Therefore, the average cost of a table is Rs. 1,500.

The correct answer is  Content analysis.

Key Points 

Inter-coder reliability:

Intercoder reliability measures the agreement between two or more coders when coding the same data. It is used to assess the coding consistency and ensure that the data are being interpreted consistently. Intercoder reliability is important in various research methods, including Content analysis.

• Content analysis is a research method that systematically analyses and interprets written, spoken, or visual content, such as text, images, or videos.
• It is commonly used in social sciences and humanities to study the meaning and significance of media content, including communication and media studies, sociology, and psychology.
• Inter-coder reliability measures are used to assess the consistency and accuracy of the coding process in content analysis.
• The coding process involves assigning categories or labels to the content being analyzed.

For example, a researcher might code newspaper articles based on their topics, such as politics, sports, or entertainment. Researchers often use inter-coder reliability measures to evaluate the agreement between coders to ensure that the coding is reliable.

• There are several measures of inter-coder reliability, including
• Cohen's kappa,
• Scott's pi, and
• Krippendorff's alpha.

These measures calculate the percentage of agreement between coders and provide a numerical estimate of the reliability of the coding process.

A high inter-coder reliability score indicates that the coders are in agreement, while a low score indicates a lack of consistency in the coding process.

By using inter-coder reliability measures, researchers can ensure that their content analysis is accurate and valid and that the results of the study are meaningful and trustworthy.

Additional Information 

• Discourse analysis: Discourse analysis is a research method used to study language use in context.
• It concerns how people use language to produce and understand social meaning and how language and context influence communication.
• It is a qualitative method that closely examines the language used in a particular context, such as a conversation, a political speech, or a news report.
• Narrative analysis:
• Narrative analysis is a research method used to study stories and narratives.
• It concerns how people use narratives to make sense of their experiences, communicate with others, and construct and maintain their identities.
• Narrative analysis is used in many fields, including psychology, sociology, and anthropology.
• It is a qualitative method that closely examines the content, structure, and form of narratives, as well as the context in which they are produced and received.
• Path analysis:
• Path analysis is a type of causal modelling used in statistics and social sciences. It is used to examine the relationships between multiple variables and determine their cause-and-effect relationships.
• Path analysis is used in psychology, sociology, and economics. It involves constructing a model that represents the relationships among variables and estimating the strength and direction of these relationships.
• Path analysis is often used to test hypotheses about the relationships between variables, to identify the key variables that contribute to a particular outcome, and to understand the complex interplay of variables in a

The correct answer is A - IV, B - III, C - II, D - I".

Important Points

Esthetic effects (D) refer to the impact that a message has on the audience in terms of its artistic or creative elements, such as the style, tone, and imagery used.

Instrumental effects (A) refer to the impact that a message has on the audience in terms of its practical or functional purposes, such as informing, persuading, or motivating them to take action.

**Prestige effects (**B) refer to the impact that a message has on the audience in terms of the speaker's credibility or reputation, such as enhancing their status or authority in the eyes of the audience.

Reinforcement effects (C) refer to the impact that a message has on the audience in terms of reinforcing their existing attitudes, beliefs, or behaviors, such as strengthening their commitment to a particular cause or ideology.

Key Points

These types of communication effects help to determine the success of a message and can influence the audience's response to the message. For example, if the goal of communication is to inform, then the instrumental effect would be the most important. If the goal is to entertain, then the aesthetic effect would be more important. Understanding these communication effects can help speakers and writers tailor their messages to achieve their desired results.

Calculation:

Let the usual time taken by the Aeroplane =x hr.

Distance =1500km

In first case-

speed= 1500/x km/h

In second case-

time taken by Aeroplane = x−1/2 hr

speed = \((\frac{1500}{x-\frac{1}{2}})\)

Increase speed = 250km/hr

\((\frac{1500}{x-\frac{1}{2}}) - \frac{1500}{x} =250\)

\(⇒ \frac{1500}{1}\times \frac{2}{2x-1} - \frac{1500}{x} =250\)

\(⇒ \frac{3000x−3000x+1500}{(2x-1)x} = 250\)

\(⇒ \frac{1500}{2x^2-x} =250\)

⇒ 6 = 2x² -x 

⇒ 2x2 -x -6 = 0

⇒ 2x2 -4x + 3x -6 = 0

x = 2, x = -3/2

so, time can not be negative x = 2

speed = \(\frac{1500}{x-\frac{1}{2}} = \frac{1500}{2-\frac{1}{2}} = 1000km/h\)

the most appropriate answer is (B), (C), (D) only.

Important Points

Case study method:

• The case study method is known for its particularistic approach, meaning it focuses on a specific case or situation.
• It is also descriptive in nature, providing detailed information about the case.
• The case study method is also considered to be inductive, as it involves drawing conclusions based on observations and evidence.

Case study:

• A case in a case study research could be an individual, organization, or institution.
• It is concerned with the in-depth study of a singular case (one person) from various possible angles for the sake of promoting his/her adjustment
• It is a qualitative research method that involves investigating a contemporary research problem within its real-life context by making use of multiple sources of data.
• It seeks to explore an area regarding which there is little understanding or prior knowledge.
• The data sources in a case study include data regarding the family and educational background and the p**rimary data collection methods employed are observation and conducting interviews.     **​

Key Points

The case study method in research is a qualitative approach that involves the in-depth examination of a specific case or situation. It is used to gain a deeper understanding of a particular phenomenon.

Some key points about the case study method include:

• Particularistic: The case study method focuses on a specific case or situation, rather than trying to generalize to a larger population.
• Descriptive: The case study provides a detailed description of the case, including relevant background information, context, and relevant data.
• Inductive: The case study method is inductive in nature, meaning that it involves drawing conclusions based on observations and evidence.
• Flexible: The case study method is flexible, allowing the researcher to gather a wide range of data, including interviews, observations, and documents.
• Multiple sources of evidence: The case study method often involves collecting data from multiple sources, including the subjects of the study, witnesses, and relevant documents.
• Interpretive: The case study method requires an interpretive approach, as the researcher must analyze and interpret the data collected.

The correct answer is Both Statement I and Statement II are true." 

Important Points

Statement I is true

• The sense that a language is a tool for communicating information and experiences, and
• When the receiver fails to relate the language used by the speaker to their own experiences and reality, this can create a psychological obstacle in communication.

Statement II is also true,

• As stereotypes held by individuals can influence the way they perceive and interpret messages.
• When someone holds stereotypes about a particular group of people, they may misinterpret or misunderstand the messages being conveyed by members of that group,
• Leading to communication breakdowns and a failure of language to reflect social reality.

In conclusion, both statements highlight the ways in which our perceptions, experiences, and biases can affect the effectiveness of communication. By recognizing these obstacles and working to overcome them, we can improve the clarity and accuracy of our communication with others.

Additional Information

Psychological obstacle:

• A psychological obstacle in communication refers to any mental or emotional barrier that prevents individuals from effectively exchanging information and ideas.
• These obstacles can take many forms, including misunderstandings, misperceptions, and unconscious biases.
• For example, if someone holds a preconceived notion about a particular topic, they may be less likely to listen to opposing views and more likely to dismiss them out of hand. This can lead to a breakdown in communication and a failure to achieve mutual understanding.

Stereotypes:

• A stereotype is a widely held, oversimplified idea about a particular group of people. Stereotypes can be based on many factors, including race, gender, religion, and nationality.
• When individuals hold stereotypes, they may unconsciously make assumptions about others based on those stereotypes, leading to misunderstandings and communication breakdowns.
• For example, if someone holds a stereotype that women are emotional and irrational, they may dismiss a woman's ideas and arguments without fully considering them. This can lead to a failure of language to reflect social reality, as the individual's biases and stereotypes prevent them from accurately perceiving and interpreting the messages being conveyed by others.

The correct answer is a social need 

Important Points 

Progressive Education: 

• As progressive education became more popular, it was advocated that young learners should be given the freedom to learn according to their preferences and likes.
• When 'constructivism' became dominant, efforts were made to provide learner-centered education through learner-controlled inputs.

According to John Dewey;

• Progressive Education is a “social need and function”, as a “process of living and growth” which includes both social and individual aspects that are mutually dependent on each other.
• “Education is not preparation for life; education is life itself.”
• It is through education that you can change the face of the world. A school is a place where children explore a new world and society, so school reflects society and the natural world.

Key Points 

• John Dewey wrote extensively on this theme and his two contributions are very appropriate here - The School and Society (1899), and Democracy and Education (1916).
• According to Dewey, education should be a collaborative process between students, teachers, and the community.
• He believed that students should be encouraged to take an active role in their own learning and that teachers should be facilitators, rather than lecturers, who help students connect new ideas to their own experiences.
• He also believed that education should be relevant to students' lives and should be structured to meet their changing needs and interests.

The correct answer is (B) and (C) only.

Oral communication is a form of communication that involves speaking, either in person or through technology such as the telephone or videoconferencing. 

Important Points

The effects of oral communication can include:

**"Personal connect":

• Oral communication allows for a more personal connection between the speaker and the listener,
• as the listener is able to hear the tone and inflection of the speaker's voice and respond with their own facial expressions and gestures.

Feedback:

• Oral communication allows for immediate feedback between the speaker and the listener,
• allowing for a more interactive and dynamic exchange of information.
• The listener can ask questions, provide clarification, or offer their own thoughts and opinions in real-time.

Additional Information

• Fragmented information: Conversation fragmentation occurs when conversations take place across numerous applications.
• Objectivity: Oral communication is not always goal specific, it is sometimes informal and unorganized.
• Absence of interpretation: It is also not a characteristic of oral communication.

Hence, (A), (D), and (E) are not true regarding oral communication.

Important Points 

The characteristics and features of written communication and oral communication has been shown in the table below,

Key Points 

Statement I: To draw an analogy between two or more entities is to indicate one or more respects in which they are similar. 

• Statement I says that to draw an analogy between two or more entities is to indicate one or more respects in which they are similar. In other words, an analogy is a comparison between two things that are similar in some way.

For example, we could draw an analogy between a lion and a whale. Both lions and whales are large, powerful predators. They both live in the wild, and they both eat meat.

Statement II: Every analogical inference proceeds from the similarity of two or more things in one or more respects to the similarity of those things in some further respect.

• Statement II says that every analogical inference proceeds from the similarity of two or more things in one or more respects to the similarity of those things in some further respect. In other words, an analogical inference is a conclusion drawn based on the similarity of two things.
• For example, if we know that lions and whales are both large, powerful predators, we can infer that they are also likely to be good swimmers. Large, powerful predators often need to swim to catch their prey.

So, both Statement I and Statement II are correct. An analogy is a comparison between two things that are similar in some way, and an analogical inference is a conclusion drawn based on the similarity of two things.

• Analogies can be used to make comparisons, to explain things, and to solve problems. They can be a powerful tool for thinking and learning.

Given:

\(\frac{(0.35)^2-(0.03)^2}{0.19}\)

Formula used:

a² - b² = (a+b)(a-b)

Calculation:

\(\frac{(0.35+0.03)(0.35−0.03)}{0.19} ​ \)

\(\Rightarrow\frac{(0.38)(0.32)}{0.19} ​ \)

2 x 0.32 = 0.64

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

Important Points 

Statement I: For the Classical Indian thinkers. inference (anuma̅na) means only syllogistic inference.

• Anumana is a Sanskrit word that means “inference” or “knowledge that follows.”
• It is one of the pramanas, or sources of correct knowledge, in Indian philosophy. Anumana is using observation, previous truths and reason to reach a new conclusion and truth.
• A simple example is observing smoke and inferring that there must be fire.

Statement II: Unlike Aristotelian Syllogism, anuma̅na involves four steps instead of three.

• Anumana consists of five steps: a hypothesis (pratijna), reason (hetu), an example (udaharana), reaffirmation (upanaya) and conclusion (nigamana).

Hence, Statement II is false.

The correct answer is (D), (E), (B), (A), (C).

Important Points 

The speed of computer memory types is determined by their proximity to the central processing unit (CPU) and the speed at which they can access and transfer data.

• The fastest type of memory is the CPU Registers, which are located within the CPU itself and provide the CPU with quick access to frequently used data.
• Next in terms of speed is Cache Memory, which is a small amount of high-speed memory located close to the CPU. This memory is used to store frequently used data and instructions, allowing the CPU to access this data quickly.
• Main Memory (RAM) is slightly slower than Cache Memory, but still provides fast access to data and instructions.
• Hard Disk is the slowest type of memory, as it uses mechanical components to access and transfer data. Finally, CD-ROM is even slower than Hard Disk, as it uses a laser to read data from the disk, which is a relatively slow process.

Key Points 

• Cache Memory :
• Cache Memory is a special very high-speed memory.
• It is used to speed up and synchronize with a high-speed CPU. Cache memory is costlier than main memory or disk memory but more economical than CPU registers.
• Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU.
• It holds frequently requested data and instructions so that they are immediately available to the CPU when needed.
• Cache memory is used to reduce the average time to access data from the Main memory.

The speed of the CPU and the ability of the CPU to run multiple processes.

• The speed of the CPU is a direct measurement of how many instructions it can complete per second.
• Processor performance can be affected by clock speed, cache size, and the number of cores the processor has.
• Increasing processor speed is the most, it will definitely improve the computer's performance as this is where computer performance depends.
• The memory capacity of most modern graphics cards ranges from 2 GB to 24 GB.
• Hard Disc Speed
• HDDs can copy 30 to 150 MB per second (MB/s), while standard SSDs perform the same action at speeds of 500 MB/s.
• RAM Size
• RAM comes shaped in physical strips.

Each strip has a set amount of memory storage space ranging from 2GB to 32 GB.

• CPU Speed
• A good processor speed is between 3.50 to 4.2 GHz, but it is more important to have a single-thread performance.

Additional Information 

The memory of the computer is divided into two categories:

1. Primary Memory

2. Secondary Memory

• Primary memory also called main memory or internal memory provides temporary storage of programs in execution and the data being processed. It is known as immediate access storage (IAS) as this is the portion of the CPU that can be accessed directly.

Primary memory can be further grouped into Random Access Memory (RAM) and Read-Only Memory (ROM). Cache memory (small, fast RAM) is designed to hold frequently used data. Let us summarise the features of each of these below.

Random Access Memory (RAM)

• This memory allows writing as well as reading of data, unlike ROM which does not allow writing of data onto it. It is volatile storage because the contents of RAM are lost when the power (computer) is turned off. If you want to store the data for later use, you have to transfer all the contents to a secondary storage device.

Read-Only Memory (ROM)

• Another type of microcomputer memory is read-only memory. Data is ‘burnt into the ROM chip at the manufacturing time. Unlike RAM, the data on the ROM is non-volatile, ie., data is not lost when the computer is switched off.

Secondary or backing Memory

• It maintains a permanent record of data and programs, maintains a store for the program and data being processed if the main memory cannot accommodate the data and program, and acts as an input/output device.

The correct answer is (A), (B), and (C).

Important Points

All of the statements about malware are true.

• A Trojan Horse is a type of malware that disguises itself as legitimate software. Once installed, it can perform a variety of malicious actions, such as stealing personal information or allowing unauthorized access to the affected system.
• A Virus is a type of malware that inserts itself into another program. It runs and spreads itself when the program is opened. This can cause the virus to infect other programs on the same computer, as well as infect other computers when the infected program is shared.
• A worm is similar to a virus, except that it does not need a program in order to run. Instead, it spreads by itself, often through networks or the Internet. Once installed, a worm can perform a variety of malicious actions, such as stealing personal information or causing a denial of service attack.

Additional Information

Malware is any software intentionally designed to cause damage to a computer, server, client, or computer network. A wide variety of malware types exist, including computer viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, wiper, and scareware.

Different types of malicious software are:

• Computer virus- A computer virus is a malicious software that self-replicates and attaches itself to other files/programs. It is capable of executing secretly when the host program/file is activated. The different types of Computer viruses are Memory-Resident Viruses, Program File Viruses, and Boot Sector Viruses. etc.
• Worm- A worm is malicious software similar to a computer virus is a self-replicating program, however, in the case of worms, it automatically executes itself. Worms spread over a network and are capable of launching a cumbersome and destructive attack within a short period.
• Trojan horses- Unlike a computer virus or a worm – the Trojan horse is a non-replicating program that appears legitimate. After gaining the trust, it secretly performs malicious and illicit activities when executed. Hackers make use of Trojan horses to steal a user’s password information and destroy data or programs on the hard disk. It is hard to detect.
• Spyware- Spyware secretly records information about a user and forwards it to third parties. The information gathered may cover files accessed on the computer, a user’s online activities, or even the user’s keystrokes.
• Rootkit- A rootkit is malicious software that alters the regular functionality of an OS on a computer in a stealthy manner. The altering helps the hacker to take full control of the system and the hacker acts as the system administrator on the victim’s system. Almost all the rootkits are designed to hide their existence.
• Phishing is the fraudulent attempt to obtain sensitive information or data, such as usernames, passwords, and credit card details, or other sensitive details, by impersonating oneself as a trustworthy entity in digital communication.
• Spoofing is the act of disguising a communication from an unknown source as being from a known, trusted source. Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (A R P), or Domain Name System (D N S) server.
• Pharming is a scamming practice in which malicious code is installed on a personal computer or server, misdirecting users to fraudulent Web sites without their knowledge or consent. Pharming has been called "phishing without a lure.

The correct answer is option 4) =$A2 + $B2

Important Points

In this spreadsheet, you want to calculate the total cost in column C. To achieve this, you need to add the lunch cost from column A and the dinner cost from column B.

In option 1), the formula uses the syntax =A$2 + $B2,

which makes the reference to cell A2 absolute (fixed) and the reference to cell B2 relative (adjustable).

This means that when the formula is copied down to cells C3 and C4, the reference to cell A2 remains fixed, while the reference to cells B3 and B4 adjusts to the new row number. This results in the correct total cost calculation in each row.

In options 2) and 3), both references are absolute, which means the formula will always refer to cells A2 and B2, regardless of the cell it is copied to. This will result in incorrect total cost calculations in cells C3 and C4.

In option 4), both references are relative, which means the formula will always refer to the current row. This will also result in incorrect total cost calculations in cells C3 and C4.

This is why option 4) =$A2 + $B2 is the correct answer.

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

Important Points

Assertion :Soil pollution due to detergents affects the root growth of plants and depresses the growth of soil micro-organisms is correct.

• Detergents contain surfactants that can have a negative impact on soil micro-organisms and plant growth.
• Soil pollution due to detergents can have serious consequences for the health and growth of plants and soil micro-organisms. Detergents contain surfactants, which are surface-active agents that can disrupt the natural soil structure and chemistry.
• The surfactants in detergents can interfere with the uptake of water and nutrients by the roots of plants, leading to reduced root growth and a decline in plant health.
• Additionally, the surfactants in detergents can also have toxic effects on soil micro-organisms, depressing the growth and activity of these important components of the soil ecosystem.

The assertion that soil pollution due to detergents affect the root growth of the plants and depresses the growth of soil micro-organisms is therefore correct.

Reason (R): Presence of detergents in soil makes the soil more acidic.

• The effect of detergents on soil pH can vary depending on the type of detergent and the specific circumstances.
• Some detergents can make the soil more alkaline, while others can have no significant effect on soil pH.
• The relationship between detergents and soil pH is complex and depends on many factors, including the composition of the detergent and the soil, the amount of detergent used, and the length of time that the detergent has been in contact with the soil.

In conclusion, while the assertion that soil pollution due to detergents affect the root growth of plants and depresses the growth of soil micro-organisms is correct, the reason given is not necessarily correct and is not a sufficient explanation of the assertion.

The correct answer is  A - III, B - IV, C - II, D - I

The correct answer is Both (A) and (R) are true but (R) is NOT the correct explanation of (A).

Important Points

Statement (A) is true.

Green hydrogen production has been identified as a critical technology for achieving carbon neutrality by 2050 as it has the potential to replace fossil fuels in many sectors, including transportation, heating and cooling, and electricity production.

Statement (R) is also true,

• as hydrogen gas has a higher energy content compared to coal.
• However, the reason stated in (R) is not the correct explanation of (A),
• as the higher energy content of hydrogen is not the sole factor driving its importance for carbon neutrality.
• Rather, the key advantage of hydrogen over fossil fuels is that when it is burned, it only produces water vapor as a byproduct, making it a clean energy source.

Therefore, both statements are true, but the reason given in (R) does not fully explain the assertion in (A).

Additional Information

• Green hydrogen
• It is produced with the help of electrolysis through electricity generated from renewable sources of energy such as solar and wind. Hence, statement 1 is correct.
• An electric current then splits the water into hydrogen and oxygen. Hence, statement 2 is correct.
• This ensures no greenhouse gas emissions as the only by-product of this process is oxygen, making it a great replacement for carbon-emitting fuels. Hence, statement 3 is correct.
• Green Chemicals like ammonia and methanol can directly be utilized in existing applications like fertilizers, mobility, power, chemicals, shipping, etc.
• Green Hydrogen blending up to 10% may be adopted in CGD networks to gain widespread acceptance.
• It is a clean-burning molecule, which can decarbonize a range of sectors including iron and steel, chemicals, and transportation.
• Renewable energy that cannot be stored or used by the grid can be channeled to produce hydrogen.
• Significance of Green Hydrogen:
• Green hydrogen energy is vital for India to meet its Nationally Determined Contribution (INDC) Targets and ensure regional and national energy security, access, and availability.
• Green Hydrogen can act as an energy storage option, which would be essential to meet intermittencies (of renewable energy) in the future.
• In terms of mobility, for long-distance mobilizations for either urban freight movement within cities and states or for passengers, Green Hydrogen can be used in railways, large ships, buses or trucks, etc.

The correct answer is increased by ~30%.

Important Points 

• Since the start of the industrial revolution, the acidity of the ocean's surface water has increased significantly due to the emission of large amounts of carbon dioxide (CO2) into the atmosphere. This CO2 reacts with seawater to form carbonic acid, which increases the acidity of the ocean.
• According to scientific studies, the ocean's surface pH has decreased by approximately 0.1 units on the pH scale, which is equivalent to a ~30% increase in acidity.
• This increase in acidity has major implications for marine ecosystems, as it can impact the ability of organisms, such as shellfish and coral, to build and maintain their skeletons and shells.
• In conclusion, the ocean's acidity has increased significantly since the start of the industrial revolution and is an important area of concern for the health of the world's oceans and marine life.

Key Points 

Ocean acidification

• In the 200-plus years since the industrial revolution began, the concentration of carbon dioxide (CO2) in the atmosphere has increased due to human actions. During this time, the pH of surface ocean waters has fallen by 0.1 pH units. This might not sound like much, but the pH scale is logarithmic, so this change represents approximately a 30 percent increase in acidity

• Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. Water and carbon dioxide combine to form carbonic acid (H2CO3), a weak acid that breaks (or “dissociates”) into hydrogen ions (H+) and bicarbonate ions (HCO3-).

• Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean’s average pH is now around 8., which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

• Acidity is a measure of the concentration of hydrogen ions (H+) in a solution, with a higher concentration of H+ ions indicating a more acidic solution. The pH scale is used to measure acidity, with a pH value of 7 considered neutral, values less than 7 considered acidic and values greater than 7 considered basic or alkaline.

The correct answer is 25% of the total faculty strength.

Important Points

The institutes would be given the freedom to recruit faculty from outside India subject to the limit of 25% of their faculty strength.

Academic Bank of Credit (ABC), proposed under the National Education Policy (NEP) 2020, will be unveiled.

Key Points 

Set up by the University Grants Commission (UGC).

• Under the ABC, students will be given multiple entry and exit options.
• This enables students to leave a degree or course and get a corresponding certification and rejoin studies after a certain time and be able to start from where they had left.
• It will also provide students with the flexibility to move between institutes while pursuing one degree or leaving
• Increases the student’s freedom in choosing their courses and academics.
• Enables the student to drop out in any year and then exchange the credits earned so far with a certificate/diploma if they are eligible.
• They can redeem the credits and rejoin the same or any other institute in the future and continue their education.
• The institutes cannot keep the students in the courses against their will to earn money

For credit evaluation & verification

• Any kind of credit evaluation & verification will be carried out by the Academic Credit Bank at regular intervals.
• If students want to transfer the credits, they need to approach the ABC for further process.
• It will help in regulating the processes with ultimate authenticity.

types of courses 

Online & offline – both types of courses are included in the scheme.

Some of the important ones include National Schemes such as–

• NPTEL
• SWAYAM
• V-LAB

Thus, the ABC will cover almost all types of courses including distance learning courses to help students of every possible stream.

Credits validity 

• The credits earned by students will be valid for seven years.
• However, the validity of credits is subject to change depending on the type of courses or disciplines.
• In such instances, ABC will provide the details of the exceptions to students.
• Even if a student takes a break or is not able to continue their education, they may redeem the earned credits in the future within the time limit of seven years.

The correct answer is "Because of the promise that the dominant ideology is in their best interest".

Key Points

• Let's consider the following statements from the above passage.
• Why would anyone consent to such an arrangement?
• While dominant ideologies may reflect the desires and interests of socially powerful groups, for these ideologies to remain dormant or hegemonic, they must also feature an additional promise.
• It is in the best interest of the marginalized groups to accept these beliefs as well.
• Put another way, members of socially powerful groups act to have their world view accepted as the universal way of thinking, and members outside these groups come to accept some of these ideologies because they appear beneficial in some way. This is referred to as a process of spontaneous consent because it is typically informal or unnoticed.

From the above statement, it is clear the correct answer is Option 4.

The correct answer is "Spontaneous consent".

Key Points

• Let's consider the following statement from the passage.
• Put another way, members of socially powerful groups act to have their world view accepted as the universal way of thinking, and members outside these groups come to accept some of these ideologies because they appear beneficial in some way. This is referred to as a process of spontaneous consent because it is typically informal or unnoticed. The best way to understand the spontaneous consent of hegemony is through an example.
• ​From the above statement it is clear that the  acceptance of domination called Spontaneous consent

Therefore, the correct answer is Option 3.

The correct answer is "Flexible appropriation "

Key Points

• Let's consider the following statements from the passage.
• A number of ideological components within a nation's higher education system may not be in the best interests of students. One dominant belief suggests that college students should pay for their own education. Despite being affected by the belief, they accept it, and the ideology survives. When such consent fails, however, the concept of hegemony also explains how dominant ideologies evolve to contain this failure through a process of flexible appropriation.
• From the above statement it is clear that The dominant ideology survives because of its Flexible appropriation.

Therefore, the correct answer is Option 2.

The correct answer is "(A) and (D) only "

Key Points

• Let's consider the following statement from the above passage.
• In such a situation, it is likely that dominant cultural institutions will absorb any challenging beliefs, integrate them into the hegemonic matrix, and re-establish the previous norm. As a result, hegemonic systems never go away.
• From the above statement of the passage it is clear that the dominant cultural institutions have the power to absorb challenges and  re-establish the previous norms.

Therefore the correct answer is Option 4.

The correct answer is "The survival of dominant ideology against the challenge".

Key Points

• Let's refer to the following sentences from the passage:
• ​As a result, hegemonic systems never go away. They simply change form through a process of constant give and take between social group. Hegemonic ideological structures maintain control in part through the never-ending process of integration and appropriation of marginalised ideologies
• The passage explains how hegemony operated in different forms and is a never-ending process.

Therefore, the correct answer is Option 4.

The correct answer is Rabindranath Tagore.

How could a lamp, which does not keep on burning, light another lamp?’ This statement is from the book titled ‘Siksha (learning). The writer of this book was Rabindranath Tagore.

Key Points The Full quotation is

"A teacher can never truly teach unless he is still learning himself. A lamp can never light another lamp unless it continues to burn its own flame.”

• Tagore argues that teachers would be strengthened through a higher status that, in India, might come through the title “guru.”
• He also argues that teachers’ education needed to improve and that it should include a thorough understanding of children’s psychology.
• Their teaching would furthermore be of higher value if teachers were given more freedom regarding their teaching methods and, to a certain degree, regarding the content of what they teach.

In the book, Tagore argues that education should not be solely focused on acquiring knowledge and skills, but should also nurture the whole person, including their emotions, creativity, and spirituality. He emphasizes the importance of developing a love and appreciation for nature and the interconnectedness of all living things.

• The quote "How could a lamp, which does not keep on burning, light another lamp?" is often cited as an example of Tagore's emphasis on the importance of inner growth and self-realization before attempting to help others. In the context of the book, this statement can be seen as a call to educators to focus on developing the inner qualities of their students before attempting to impart knowledge or skills to them.

Overall, "Siksha" is a thought-provoking and philosophical book that reflects Tagore's deep insights on education and the human condition. It is a timeless work that continues to inspire and challenge readers today.
