UGC NET Paper 1: Held on 6th Dec 2023 Shift 1 (Previous Year Paper)

The correct answer is 2) Schemas.

 Key Points

• Schemas are organized bodies of knowledge stored in memory that influence how we interpret, store, and recall new information. They act as mental frameworks that help us make sense of the world around us.

Characteristics of Schemas:

• Schemas are organized and structured.
• They are based on past experiences and knowledge.
• They can be general or specific.
• They can be updated and modified as we learn new information.

Functions of Schemas:

• Schemas help us to interpret new information by providing a framework for understanding it.
• They help us to store new information by linking it to existing knowledge.
• They help us to recall information by providing cues and prompts.
• They help us to make predictions about the world around us.

Examples of Schemas:

1. The schema for a "dog" might include information about its physical characteristics, behavior, and typical interactions with humans.
2. The schema for a "restaurant" might include information about its layout, menu, and typical customer interactions.

The correct answer is - (A) and (B) Only.

Key Points(A) No liquids are beverages.

• This means that if something is a liquid, then it is not a beverage.

(B) No beverages are liquids.

• This means that if something is a beverage, then it is not a liquid.

Statements (A) and (B) are logically equivalent because they both establish a mutual exclusion between liquids and beverages.

• If no liquid can be a beverage, it logically follows that no beverage can be a liquid.

Additional InformationThe logical relations and equivalences between different categorical statements.

• This is a foundational aspect of logic, especially relevant in categorical logic,
• This deals with the relations between categories (or sets) and their members.
• The key to understanding logical equivalence is to grasp how different formulations of statements can express the same underlying logical relationship.

The traditional categorization includes:

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

Given:

First term of the A.P. = 3

50^th term of the A.P. = 199

Formula used:

n^th term of the A.P. = a + (n - 1)d

Sum of n terms in A.P. = n/2[2a + (n - 1) × d]

where, a = first term and d = common difference.

Calculation:

According to the question,

50^th term = 3 + (50 - 1)d 

⇒ 199 = 3 + 49d

⇒ 196 = 49d

⇒ d = 4

Sum of 50 terms = 50/2[2 × 3 + (50 - 1) × 4]

⇒ 25[6 + 49 × 4]

⇒ 25 × 202

⇒ 5050

∴ The correct answer is 5050.

The correct answer is - Faster more expensive per unit of storage and not persistent.

Key PointsPrimary Storage (a.k.a. Main Memory or Primary Memory):

• Speed: Primary storage, which includes RAM (Random Access Memory), is significantly faster than secondary storage devices (like HDDs and SSDs).
• It is directly accessible by the CPU, which allows for quick data retrieval and storage necessary for running applications and the operating system.
• Cost: On a per unit of storage basis, primary storage is more expensive than secondary storage.
• This is because it's designed for speed and quick access, utilizing more advanced and expensive technology relative to the larger, slower secondary storage.
• Persistence: Primary storage is not persistent (volatile).
• It’s used for data that the system is currently working with, as opposed to long-term storage.

Additional InformationSecondary Storage

• Speed: Secondary storage devices, such as hard disk drives (HDDs), solid-state drives (SSDs), and optical disks, are slower in comparison to primary storage.
• They are used for storing data that is not currently in use by the CPU.
• Cost: These storage mediums are less expensive on a per unit basis compared to primary storage.
• The lower cost makes them suitable for the mass storage of data.
• Persistence: Secondary storage is persistent (non-volatile).
• This makes it ideal for long-term data storage.

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

Key Points

• Statement (I): The Nalanda University of ancient India attracted students from various parts of Asia. (True)
• Historical evidence shows that Nalanda University was indeed a renowned center of learning that attracted students from across Asia, including China, Korea, Japan, Tibet, and Southeast Asia.
• Statement (II): Nalanda University was overshadowed by the universities in Europe and Arabia immediately after its establishment. (False)
• Nalanda University flourished from the 5^th to the 12^th century CE. Universities in Europe and Arabia emerged much later, with the first European universities appearing in the 11^th and 12^th centuries and the first major centers of learning in the Arab world developing around the 8^th and 9^th centuries.

Therefore, Nalanda University couldn't have been overshadowed by universities in Europe and Arabia "immediately after its establishment" as these universities simply didn't exist during Nalanda's peak period.

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

Key PointsStatement (I): Correct.

• Millennium Development Goals (MDGs) were indeed primarily targeted at developing or poor countries.
• They aimed to address issues such as poverty, hunger, disease, and lack of access to education and healthcare in these nations.

Statement (II): Correct.

• Sustainable Development Goals (SDGs) are targeted at all countries regardless of their development status.
• They were adopted by all United Nations Member States in 2015 as a universal call to action to end poverty, protect the planet, and ensure prosperity for all by 2030.
• Therefore, SDGs encompass a broader scope and are applicable to both developed and developing countries.

Additional InformationThe Sustainable Development Goals:

• The Sustainable Development Goals (SDGs) are a set of 17 global goals
• They were adopted by the United Nations General Assembly in 2015 as part of the 2030 Agenda for Sustainable Development.
• Each goal is accompanied by specific targets and indicators to track progress towards achieving them by 2030.

The correct answer is Information.

Key PointsOne of the four conversational maxims included in philosopher H.P. Grice's cooperative principle is the quantity maxim. In particular, giving just the appropriate amount of information during a conversation is covered by the Quantity Maxim. Grice's Cooperative Principle states that in order to achieve effective communication, participants in a conversation are typically expected to contribute the appropriate amount of information—that is, neither too much nor too little.

• Information:- The Quantity Maxim emphasizes the importance of contributing a sufficient amount of information to convey the intended meaning without being overly verbose or withholding necessary details.
• It promotes a balance in communication, ensuring that participants share an appropriate and adequate amount of information for the conversation to proceed smoothly.
• The goal is to avoid ambiguity or misunderstanding by providing enough information to convey the speaker's intended message.

Additional Information

• Paradigms are fundamental models or frameworks used in a particular field.
• They are not directly related to the amount of information in a conversation.
• Syntagms refer to the combination of words that form a grammatical unit, like a noun phrase or verb phrase.
• They are not directly related to the quantity of information either.
• Similes are figures of speech comparing two things using "like" or "as." While they can be used to convey information, they are not the primary focus of the quantity maxim.

The correct answer is - Positivism.

Key Points

• Positivism is an epistemological position that originates from the philosophy of science.
• It argues for the application of the methods and approaches used in the natural sciences to the study of social reality, and beyond.
• Key features of positivism include:
• ​Empiricism: Positivism values empirical evidence from observations and experiments as the foundation of knowledge.
• Objectivity: It emphasizes the need for researchers to remain detached and unbiased, ensuring findings are fact-based.
• Scientific Method: Advocates for applying natural science techniques—hypothesis testing and quantification—to understand social phenomena.
• Logical Positivism: Focuses on logical analysis and empirical verification, considering only empirically verifiable or analytically true statements as meaningful.
• Criticism: Positivism is criticized for oversimplifying human behavior and social complexity, facing opposition from perspectives like interpretivism and critical theory, which highlight the limits of applying natural science methods to social studies.

Additional Information

• Interpretivism:
• Stresses understanding the subjective meaning behind social phenomena.
• Prioritizes qualitative methods and the context in which social actions occur.
• Objectivism:
• Believes that social phenomena and their meanings have an independent existence from social actors.
• Focuses on the objective study of social structures and patterns.
• Constructionism:
• Argues that social realities are constructed through human interactions and perceptions.
• Emphasizes the importance of understanding the processes through which social meanings are created and maintained.

Key Points Statement (I) : According to Buddhism, linguistic communication should be used to adopt moral stance.

• Statement I is correct:
• Buddhism emphasizes the importance of ethical conduct and moral behavior. The Buddha taught that right speech is one of the five precepts that all Buddhists should follow. Right speech includes using language that is truthful, kind, and beneficial.
• It also includes avoiding gossip, slander, and harsh speech. By using language in a moral way, Buddhists can create a more harmonious and compassionate world.

Statement (II) : Critical introspection is not preferred by Buddhists as part of intra - personal communication.

• Statement II is incorrect:
• Buddhism encourages critical introspection as a means of understanding oneself and one's place in the world. The Buddha taught that we should examine our thoughts, words, and actions to see if they are in line with our values.
• This process of self-reflection can help us to identify our strengths and weaknesses, and to make changes in our lives that will lead to greater happiness and well-being.

Therefore, the correct answer is option 3) Statement I is correct but Statement II is incorrect.

The correct answer is 3) R.

Key Points

• R is a programming language and software environment for statistical computing and graphics. It is a free and open-source software, which means that anyone can use it, modify it, and redistribute it. R is widely used by statisticians, data miners, and data scientists for a variety of tasks, including:
• Data manipulation and cleaning
• Statistical analysis
• Data visualization
• Machine learning
• Text mining
• R has a large and active community of users and developers who contribute to its development and support. There are also many packages available for R that extend its functionality.

Additional Information

MINITAB:

MINITAB is a statistics package, commonly used for quality improvement and statistics education. It is a commercial software product requiring a paid license. It is not open-source.

The correct response is Both (A) and (R) are correct and (R) is the correct explanation of (A).

Key Points

• Assertion (A) states that DDT bioaccumulates in tissues of many species including humans. This assertion is correct. DDT, or dichlorodiphenyltrichloroethane, is a synthetic pesticide that was widely used in the past for insect control. One of the characteristics of DDT is its ability to bioaccumulate, which means it builds up in the tissues of organisms over time.
• When DDT is introduced into the environment, it is absorbed by organisms through various pathways such as ingestion or inhalation. Once inside the body, DDT tends to accumulate in fatty tissues and organs. This bioaccumulation occurs because DDT is relatively insoluble in water but readily soluble in fats and oils.
• Reason (R) states that DDT is relatively insoluble in water but readily soluble in fats and oils. This reason is also correct. DDT's chemical properties make it highly lipophilic, meaning it has an affinity for fats.
• This property is what enables DDT to accumulate in the fatty tissues of organisms. Additionally, DDT's low water solubility contributes to its persistence in the environment, as it tends to remain in soils and sediments rather than being easily washed away by water.

 

Therefore, both the assertion and reason are correct, and the reason provides a valid explanation for why DDT bioaccumulates in the tissues of many species, including humans.

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

Key Points 

Statement I: According to the classical Indian school of logic (Nyaya), the argument "Sound is eternal because it is audible" is fallacious.

Explanation of Statement I:

In Nyaya, one of the classical Indian schools of logic, the argument "Sound is eternal because it is audible" is considered fallacious. This is because the premise "Sound is audible" does not logically lead to the conclusion "Sound is eternal." The argument commits a fallacy known as "ignorance of cause," where the connection between audibility and eternity is not logically justified. In Nyaya, arguments are evaluated based on their logical validity, and this argument does not meet the criteria for sound reasoning.

Statement II: According to the classical Indian school of logic, the argument "Sound is eternal because it is audible" commits the fallacy of irregular middle term where the middle term is too wide.

Explanation of Statement II:

This statement is incorrect. In classical Indian logic, the concept of "irregular middle term" typically refers to a situation where the middle term in a syllogism (the term that connects the subject and predicate) is not properly defined or is too broad, leading to an invalid conclusion. However, in the given argument, the issue is not with the middle term being too wide; instead, it's about the lack of logical connection between audibility and eternity. Therefore, Statement II does not accurately describe the fallacy committed in this argument according to classical Indian logic.

Additional Information 

• Nyaya, one of the six classical Indian schools of philosophy, is known for its systematic approach to logic and epistemology. It emphasizes the importance of valid reasoning and rigorous analysis of arguments.
• In Nyaya, arguments are evaluated based on their structure and logical coherence. Fallacies are identified when there are errors in reasoning that lead to invalid conclusions.
• The Nyaya system provides methods for analyzing arguments and detecting fallacies to ensure the validity of knowledge claims.

The logic follows here is:

 

Hence, the correct answer is "YA".

Key Points

• The Hunter Commission was appointed by the British government in 1882 to inquire into the state of education in India.
• The commission made a number of recommendations, including the expansion of private enterprise in higher education. The commission believed that private colleges and universities could play a valuable role in meeting the growing demand for higher education in India.
• The commission also recommended that the government provide financial assistance to private institutions to help them improve their quality.

The other options are incorrect:

• Abolition of higher education in India: The Hunter Commission did not recommend abolishing higher education in India. In fact, the commission recommended expanding access to higher education.
• Restricting women's entry into colleges: The Hunter Commission did not recommend restricting women's entry into colleges. In fact, the commission recommended that women be given equal access to higher education.
• Encouraging establishment of more and more public universities in rural India: The Hunter Commission did not specifically recommend encouraging the establishment of more public universities in rural India. However, the commission did recommend expanding access to higher education in rural areas.

Therefore, the correct answer is option 3) Participation of private enterprise in higher education.

Key Points 

• The University Grants Commission (UGC) was established in 1956 to promote and coordinate university education in India. During the Second Five Year Plan (1956-1961), the UGC took a number of steps to improve the quality of higher education in India. These steps included:
• Introduction of a three-year degree course: The UGC recommended that all universities adopt a three-year degree course instead of the traditional two-year course. This was done to provide students with a more comprehensive and rigorous education.
• Improvement in libraries and laboratories: The UGC provided grants to universities to improve their libraries and laboratories. This was done to ensure that students had access to the resources they needed to succeed in their studies.
• Increase in the salaries of university teachers: The UGC recommended that the salaries of university teachers be increased. This was done to attract and retain the best and brightest minds in academia.

The other options are incorrect:

• (D) No new departments were approved in the universities: This is incorrect. The UGC actually approved the establishment of a number of new departments in universities during the Second Five Year Plan.
• (E) Hindi was made the optional medium of instruction besides local languages in all Indian universities: This is incorrect. Hindi was not made the optional medium of instruction in all Indian universities during the Second Five Year Plan.

 

Therefore, the correct answer is option 1) (A), (B) and (C) Only.

The correct response is (A) - (IV), (B) - (I), (C) - (II), (D) - (III) .

 

 Key Points

A) Window: A window in a graphical user interface (GUI) is a visual area containing some kind of user interface. It typically represents an application or a specific instance within an application and can be resized, minimized, maximized, or closed. Therefore, option (A) - (IV) matches with (A).

B) Icon: Icons are graphical representations of programs, files, or functions. They can represent a folder, a program, or a file, as mentioned in the description. Therefore, option (B) - (I) matches with (B).

C) Menu: A menu is a list of options or commands presented to the user, typically through a drop-down list or a pop-up menu. It contains lists of options for a certain program, which aligns with option (C) - (II).

D) Pointer: The pointer, often represented by an arrow or other symbol, is used to interact with elements on the screen, such as selecting menu options, clicking icons, or opening/closing windows. Hence, it matches with option (D) - (III).

Therefore, the correct match is option: (A) - (IV), (B) - (I), (C) - (II), (D) - (III).

 

Additional Information

• Graphical User Interface (GUI) is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators as opposed to text-based interfaces, typed command labels, or text navigation.

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

Key Points

(B) Saha Institute of Nuclear Physics:

• Saha Institute of Nuclear Physics (SINP) is an institution for basic research and training in physical and biophysical sciences located in Kolkata, India.
• Institute of Nuclear Physics (INP) was formed in 1949, which was later renamed as Saha Institute of Nuclear Physics (SINP) after the untimely death of Prof Saha in 1956 which falls under the time frame of the First and Third Five Year Plans.
• It was established during the Second Five Year Plan (1956-1961).

(C) Lok Bharati:

Lok Bharati is an educational institution located in Santiniketan, West Bengal, India.

Established in 1953, Lok Bharati falls under the time frame of the First and Third Five Year Plans. It was established during the Second Five Year Plan (1956-1961).

(D) Gandhigram Rural Institute:

Gandhigram Rural Institute (GRI) is a rural university located near Dindigul in Tamil Nadu, India.

Established in 1956, GRI falls under the time frame of the First and Third Five Year Plans. It was established during the Second Five Year Plan (1956-1961).

 Additional Information

India's Third Five Year Plan (1961-1966) aimed at food self-sufficiency and economic growth. It focused on modernizing agriculture, developing heavy industries, and building infrastructure.

The wars forced a change in defense spending, but the plan laid the foundation for future development by highlighting the need for diversification and self-reliance.

Solution:-

(144)_{8 =}18²+ 48¹ + 4*8⁰ = 64 +32 +4= (100)10

(175)₈= 18²+ 78¹ + 5*8⁰ = 64 +56 +5 = (125)10

Now, 

 (100)10 +  (125)10  = (225)10

To convert the decimal number (225)₁₀ to octal, you can use repeated division by 8.

• Divide 225 by 8: 225 ÷ 8 = 28 with a remainder of 1.
• Divide the quotient (28) by 8: 28 ÷ 8 = 3 with a remainder of 4.
• Divide the new quotient (3) by 8: 3 ÷ 8 = 0 with a remainder of 3.
• Now, read the remainder in reverse order: 341.

We can write it (341)_8.

The correct response is (A), (B) and (E) Only.

Key Points

• (A) Both are concerned with data reduction: While qualitative and quantitative research use different methods for collecting data, both ultimately aim to analyze and condense it into meaningful insights.
• (B) Both are concerned with variation in data: Both methods seek to understand how variables interact and vary within their respective frameworks. Quantitative research analyzes numerical variations, while qualitative research explores diverse perspectives and experiences.
• (E) Both are concerned with answering research questions: Regardless of their different approaches, both quantitative and qualitative research are conducted to seek answers to specific questions and gain knowledge about a particular phenomenon.

Additional Information

• (D) Both lay emphasis on generalization: This statement is not universally true. Quantitative research often seeks to generalize findings to broader populations based on statistical analysis, whereas qualitative research tends to focus on understanding specific contexts and may not prioritize generalization in the same way.

Calculation:

Let's denote the profit percentage in 2018 as P₂₀₁₈ and the profit percentage in 2021 as P2021.

According to the information provided: + 60% 

⇒ P2021 = P2018 + 60% of P2018

⇒ P2021 = 15% + 60% × 15%

⇒ P2021 = 24%

Now, let's denote the expenditure in 2021 as E2021.

Using the profit percentage formula:

⇒ Income = Expenditure + Profit Percentage × Expenditure

⇒ Income₂₀₂₁ = E₂₀₂₁ + 24% × E₂₀₂₁

⇒ 359.6 = E2021 + 24% × E2021

⇒ 1.24 × E₂₀₂₁ = 359.6

​⇒ E2021 = 290 (approx)

Now, the percent increase in expenditure from 2020 to 2021:

​⇒ ((290−210) / 210 ) ×100

⇒ (80 / 210 ) ×100

⇒ 38.1 %

∴ The correct answer is "38%".

Calculation:

Income of the company in 2018 = 192 + 15% of 192

⇒  220.8

Similarly, Income of the company in 2020 = 210 + 20% of 210

⇒ 252

The average of the income of the Company in 2018 and 2020,

⇒ (220.8 + 252) / 2

⇒ 236.4

∴ The correct answer is "236.4".

Calculation:

Profit in 2018 = 0.15 × 192

⇒  28.8

Now, Profit in 2020 = 0.20 × 210

⇒ 42

Required percentage = { (42 - 28.8) / 28.8 } × 100

⇒ (13.2 / 28.8 ) × 100

⇒ 45.83%

∴ The correct answer is "45.83%".

Calculation:

In 2022, the expenditure of the company,

⇒ (100 % + 15 %) Expenditure in 2019

⇒ 115 % of 248

⇒ 285.2

Now, the income of the company in 2022 is,

⇒ 285.2 + (−12%) × 285.2

⇒ 285.2 − 34.224

⇒ 250.976

∴ The correct answer is "250.976".

Calculation:

Profit of the Company in 2018 = 15% of 192 

⇒ 28.8

So, the loss incurred by the Company in 2019

⇒ 28.8 + 33.2

⇒ 62

Now, the loss percentage in 2019 is,

⇒ (62/248) × 100

⇒ 25%

∴ The correct answer is "25%".

The correct response is both Statement I and Statement II are incorrect 

Key Points Statement I: "The ability to generate unusual, yet appropriate, responses to problems or questions is known as convergent thinking."

• This statement is incorrect. Convergent thinking actually refers to the ability to narrow down multiple possible solutions to a problem to find the single best solution. It involves focusing on finding one correct answer based on logic and knowledge, rather than generating multiple possibilities.
• Statement I incorrectly defines convergent thinking as generating unusual responses.

Statement II: "The ability to produce responses that are based primarily on knowledge and logic is known as divergent thinking."

• This statement is also incorrect. Divergent thinking involves generating multiple possible solutions to a problem. It emphasizes creativity, flexibility, and the exploration of different ideas and perspectives rather than narrowing down to a single correct answer.
• Divergent thinking often leads to a variety of responses rather than just one, as it encourages exploring various possibilities.
• Statement II incorrectly defines divergent thinking as relying solely on knowledge and logic.

So, the correct answer is both Statement I and Statement II are incorrect.

The correct answer is: (B), (C) and (D) Only

Key Points 

Proxemics is the study of how humans use and perceive space in communication. Here's how each option relates to proxemics:

• (B) Crowding: Proxemics includes the study of crowding and how people react to different levels of crowding in their environment. It examines how individuals perceive and respond to the invasion of their personal space.
• (C) Territoriality: Proxemics involves the study of territoriality, which refers to how individuals establish and defend territories, both physical and psychological. It explores how people mark and protect their spaces and how this impacts communication and social interactions.
• (D) Personal space: Proxemics focuses heavily on the concept of personal space, which is the area surrounding an individual that they consider as their own. It examines how people use personal space to regulate social interactions and how violations of personal space can affect communication and comfort levels.

Additional Information

• (A) Facial expressions: While facial expressions are important in communication, they are not specifically related to proxemics, which is more concerned with spatial relationships and the use of space in communication.
• (E) Eye contact: Eye contact is also crucial in communication, but it falls more within the realm of nonverbal communication rather than proxemics, which is primarily concerned with spatial behavior.

Shortcut Trick

Convert Speed to m/s: 63 × 5/18 = 17.5 m/s.

Total Distance (Train + Platform) = Speed × Time = 17.5 × 20 = 350 m.

Platform Length = Total Distance − Train Length = 350 − 100 = 250 m.

∴ The correct answer is 250 m.

Alternate Method

Given:

• Speed of the train = 63 km/hr

• Time taken to cross the platform = 20 s

• Length of the train (L_t) = 100 m

Formula:

Total Distance = Length of Train + Length of Platform = Speed × Time

Calculations:

⇒ Speed in m/s = 63 × (5/18) m/s

⇒ Speed = 7 × (5/2) = 17.5 m/s

⇒ Let Platform Length be L_p

⇒ Total Distance = L_t + L_p = 100 + L_p

⇒ 100 + L_p = 17.5 × 20

⇒ 100 + L_p = 350

⇒ L_p = 350 − 100

⇒ L_p = 250 m

The calculated length of the platform is 250 m, which corresponds to Option (3).

∴ The correct answer is 250 m.

Additional Information

Unit Conversion

To convert speed from km/hr to m/s, multiply by 5/18. To convert m/s to km/hr, multiply by 18/5.

Crossing Stationary Objects

When a train crosses a platform, bridge, or tunnel, the total distance covered is (Length of train + Length of the object).

Relative Speed

If two objects move in the opposite direction, relative speed = S₁ + S₂. In the same direction, relative speed = |S₁ − S₂|.

The correct answer to the question on identifying sampling issues that are problematic in online surveys is (C) and (D) only. This choice reflects the common concerns regarding the representative nature and potential biases in online survey methodologies.

Key Points

• Option (A), "Many people use more than one internet service provider," is not inherently a sampling issue for online surveys. While it might impact aspects related to the technical delivery or tracking of survey participation, it doesn't directly affect the representativeness or bias of the sample in the manner that options (C) and (D) do.
• Option (B), "Every person has only one (unique) email address," is incorrect as stated and is not typically a sampling issue. In reality, many people have multiple email addresses, but the statement itself (as phrased in the query) doesn't represent a challenge to sampling methodologies in the context of this discussion.
• Option (C), "A household may have one computer but several users," is recognized as a sampling issue. This situation can lead to underrepresentation or overrepresentation of individuals within a household if not properly accounted for, as different members may have varying access to the survey depending on household dynamics and computer usage patterns.
• Option (D), "Internet users are a biased sample of the population," is a significant sampling concern. Online surveys inherently bias towards those with internet access, thereby potentially excluding segments of the population that are less likely to use or have access to the internet, such as older individuals or those in lower socioeconomic brackets.

Therefore, the issues that accurately reflect sampling problems in online surveys are specifically tied to the access and representation biases (options C and D), whereas options A and B do not directly address core sampling challenges faced by these survey methodologies.

The correct answer is Calcutta.

Key Points

• The University of Punjab was established in 1882 in Lahore, which is currently in Pakistan.
• At that time, the University of Calcutta had jurisdiction over a vast area in northern India, including parts of current-day Pakistan.
• Establishing the University of Punjab aimed to alleviate the pressure on the University of Calcutta by taking on some of the colleges affiliated with it.

Additional Information

• Higher education was becoming more and more in demand throughout British India during the colonial era.
• The University of Calcutta functioned as a focal point for higher education and was the country's first modern university, having been founded in 1857.
• But as education became more and more in demand in the northwest of India, which encompasses modern-day Pakistan, a university tailored to the unique educational needs of that region was required.
• The University of Punjab was established in Lahore in 1882 to meet this need.
• The new university was to be located in Lahore, a prominent city in the northwest.
• In order to relieve pressure on the University of Calcutta by decentralizing educational resources and offering higher education opportunities to students in the Punjab region, the University of Punjab was strategically established.

The correct answer is: Agenda 21 

Key Points

• The Convention on Biological Diversity (CBD) is dedicated to promoting sustainable development, which is a concept outlined in Agenda 21.
• Agenda 21 is a comprehensive plan of action adopted at the United Nations Conference on Environment and Development (UNCED) held in Rio de Janeiro, Brazil, in 1992.
• It provides a blueprint for sustainable development, emphasizing the need for environmental protection, social equity, and economic development to meet the needs of the present without compromising the ability of future generations to meet their own needs.
• Therefore, the principles of sustainable development promoted by the Convention on Biological Diversity are aligned with those outlined in Agenda 21.

Additional Information

• The Convention on Biological Diversity (CBD) is an international treaty established to address the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits arising from the utilization of genetic resources.
• It was opened for signature at the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992, often referred to as the Earth Summit.

The correct answer is - Referential function.

Key PointsThe referential function of language is one of the six functions identified by Roman Jakobson, a linguistic and literary theorist.

• It primarily aims to convey factual information.
• Centers on the context or referent.
• Predominantly used in scientific, technical, journalistic, and academic communications.
• Emphasizes clear, precise, and objective language to minimize misunderstandings and ambiguities.
• It exists alongside other language functions like emotive, conative, phatic, metalingual, and poetic functions, as identified by Roman Jakobson.
• Essential in fields requiring accurate information transmission and understanding, underscoring the need for language alignment with communicative goals.

Additional InformationThe six functions of language identified by Roman Jakobson:

• Referential (Denotative): Conveys factual information about the world.
• Emotive (Expressive): Expresses the speaker's emotions or attitude.
• Conative (Imperative): Influences the behavior or response of the receiver.
• Phatic: Establishes, maintains, or checks the communication channel.
• Metalingual (Metalinguistic): Discusses or clarifies language itself.
• Poetic: Focuses on the aesthetic quality and form of language.

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

Key Points

• (A) Objective formulation: Defining clear learning objectives is essential for crafting an effective learning experience. It helps teachers and students understand what knowledge, skills, or attitudes should be acquired by the end of the instruction.
• (B) Selection of teaching methods and materials: Choosing appropriate methods (e.g., lectures, discussions, group work) and materials (e.g., textbooks, simulations, technology) aligns with the learning objectives and caters to diverse learning styles.
• (C) Content analysis: Understanding the depth and complexity of the content being taught helps determine the appropriate level of instruction and identify potential challenges students might face.
• (D) Selection of evaluation devices: Choosing suitable assessments (e.g., tests, projects, observations) allows teachers to measure student learning against the set objectives and identify areas for improvement in teaching or learning strategies.

The correct answer is 4) (A), (C) and (E) Only.

Key Points 

(A) It is the result of conversion of solid biomass into gaseous fuels: This is true. Producer gas is indeed produced by the gasification of solid biomass materials such as wood, charcoal, agricultural residues, or coal.

(C) It can be used as fuel in internal combustion engines: This is true. Producer gas can be used as a fuel in internal combustion engines after appropriate cleaning and conditioning.

(E) Hydrogen and methane present in Producer Gas determine its heating value: This is true. The heating value of producer gas depends on the composition of gases it contains, primarily hydrogen and methane.

The fallacy committed in the statement is option 4) False cause.

Key Points 

The statement suggests a causal relationship between the increase in the number of laws and the increase in the number of crimes committed. However, just because two events happen simultaneously or in sequence does not necessarily mean that one caused the other.

This is a classic example of the false cause fallacy, also known as correlation does not imply causation.

The argument incorrectly assumes that adding more laws directly causes an increase in crime, without considering other factors that might be contributing to the rise in crime rates. It fails to account for potential correlations between the increase in laws and other social, economic, or environmental factors that could be influencing crime rates.

Additional Information

• Red herring: This fallacy occurs when someone introduces an irrelevant topic to divert attention from the original issue. While the argument might be diverting attention from other potential causes of crime, it's not presenting an entirely irrelevant topic.
• Straw man: This fallacy involves misrepresenting or exaggerating an opponent's argument to make it easier to attack. However, the argument in question doesn't misrepresent another position; it simply draws a faulty conclusion based on a false cause.
• Slippery slope: This fallacy occurs when it is assumed that a particular action will inevitably lead to a series of increasingly undesirable consequences. While there's a hint of this in the argument (suggesting that more laws will lead to more crime), the primary fallacy is the false cause, as it incorrectly assumes a causal relationship between two events without sufficient evidence.

The correct answer is - 21.1 Giga Bytes.

Key Points

• To calculate the storage required for 2 hours of video footage, we first need to determine the storage required for one minute and then multiply by the total number of minutes in 2 hours.
• 1 minute of video requires 180 MB.

So, for 60 minutes (1 hour), the storage required would be:180 times 60 = 10800 

For 2 hours, the storage required would be double that:  10800 times 2 = 21600 MB

To convert megabytes (MB) to gigabytes (GB), knowing that 1 GB = 1024 MB, the calculation is: 21600/1024 = 21.09375 GB

The closest answer is: 3) 21.1 Giga Bytes

The correct answer is - Both statements I and II are correct.

Key Points

Statement (I):​ This statement is correct.

• IPv4 addresses use 32 bits (4 octets) to represent a device's address on a network.
• IPv6 addresses, the next generation of IP addressing, utilize 128 bits (16 octets) for the address.
• Since 128 is four times larger than 32, IPv6 addresses are indeed four times the size of IPv4 addresses.

 

Statement (II): This statement is also correct.

 

IP Address:

• An IP address does more than just act as a unique identifier; it also facilitates the routing of network traffic to and from the device within a network.
• Though it can sometimes provide a rough geographical location, its primary purpose is for network interface and routing.

MAC Address:

• A Media Access Control (MAC) address is a unique hardware identifier embedded in a device's network interface card (NIC).
• It operates at the local network level (like your home Wi-Fi) to identify specific devices communicating with each other.

The correct answer is: (A) and (D) Only

Key Points

According to the square of opposition in traditional logic, there are four types of categorical propositions: A (universal affirmative), E (universal negative), I (particular affirmative), and O (particular negative). Each type of proposition has a specific relationship with the others:

​

Proposition (A) is an A proposition, which makes a universal affirmative claim about mammals and vertebrates. It asserts that all mammals belong to the category of vertebrates.

Proposition (D) is an I proposition, which makes a particular affirmative claim about mammals and vertebrates. It asserts that some mammals do not belong to the category of vertebrates.

• The contradiction arises in that if proposition (A) is true, it implies that every single mammal is a vertebrate, leaving no room for any mammal to not be a vertebrate. In this case, proposition (D) would be false.
• Conversely, if proposition (D) is true, it implies that there are at least some mammals that are not vertebrates, contradicting the claim made in proposition (A) that all mammals are vertebrates.

 

Therefore, if one of these propositions is true, the other must be false, and vice versa. This establishes the relationship between propositions (A) and (D) as contradictories, making them related according to the square of opposition.

Hence, the correct answer is (A) and (D) Only.

The correct answer is - (C), (A), (D), (B)

Key Points

• Screening (C):
• The first step in the water treatment process.
• Removes large floating objects and debris.
• Coagulation (A):
• The second step in the water treatment process.
• Involves adding chemicals (coagulants) to the water to aggregate smaller particles into larger flocs.
• Sedimentation (D):
• The third step in the water treatment process.
• Allows the larger flocs formed during coagulation to settle out of the water.
• Filtration (B):
• The final step in the water treatment process.
• Removes any remaining fine particles and impurities.

Additional Information

• Water Treatment Process:
• The goal is to provide safe, clean drinking water to the public.
• Additional steps may include:
• Disinfection: Addition of chemicals like chlorine to kill harmful bacteria and viruses.
• pH Adjustment: Balancing the acidity or alkalinity of water to prevent corrosion and enhance effectiveness of disinfectants.
• Importance:
• Ensures water meets health and safety standards.
• Prevents waterborne diseases and contamination.

Formula used: 

A = P(1 + \({r \over 100}\))^t

Calculation:

Let the principal be P

A = 2P

⇒ 2P = P(1 + \({r \over 100}\))⁴

⇒ 2 = (1 + \({r \over 100}\))⁴

⇒ 2^1/4 = (1 + \({r \over 100}\))

⇒ 2^1/4 - 1 = \({r \over 100}\)

⇒ 1.1892 - 1 = \({r \over 100}\)

⇒ r = 18.92%

Hence, 18.9% is the correct answer.

The correct response Option 4) (A), (B), (C), and (D)

Key Points

(A) You need to know what is already known in connection with your research area:

• This reason is essential for writing a literature review. Understanding existing research helps you build upon prior knowledge, avoid duplication, and identify gaps in the literature.

 

(B) It may help you to develop an analytic framework:

• A literature review provides insight into different theoretical perspectives and methodologies used in previous studies. This understanding aids in developing a robust analytic framework for your own research.

 

(C) It will help with the interpretation of your findings:

• By reviewing existing literature, you gain context and comparative data that assist in interpreting your own research findings. This enables you to discuss your results in relation to prior studies and theoretical frameworks.

(D) It may suggest further research questions for you:

• Identifying gaps or unanswered questions in the literature can inspire new research directions. A comprehensive literature review often leads to the formulation of new research questions or hypotheses.

Additional Information 

A literature review serves multiple purposes beyond those listed. It helps researchers to:

• Identify key scholars and seminal works in their field.
• Evaluate the methodological approaches used in previous studies.
• Provide a theoretical framework for their research.
• Demonstrate their understanding of the broader scholarly conversation within their discipline.
• Justify the significance and originality of their research project

The correct response is All rectangles are squares.

Key Points

• A square of opposition is a diagram that represents the logical relations between four propositions. Given the statement "Some rectangles are not squares," we are working within the realm of categorical logic.
• This statement is an I statement in traditional logic (Some S is not P), indicating that there is at least one instance of the subject (rectangles) that does not fall under the predicate category (squares).
• If it's true that "Some rectangles are not squares," it directly contradicts the universal affirmation that all rectangles are squares. It implies there is at least one rectangle that isn't a square, making it impossible for all rectangles to be squares.
• According to the square of opposition, a particular negative statement (Some S is not P) makes the universal affirmative statement (All S is P) necessarily false.

Additional Information

The square of opposition helps in understanding the logical relationships between statements by illustrating how the truth of one proposition affects the truth values of others related to it. The basic structure involves:

• Universal affirmative (A): All S are P
• Universal negative (E): No S are P
• Particular affirmative (I): Some S are P
• Particular negative (O): Some S are not P

The correct answer is: 4) Statement I is incorrect but Statement II is correct.

Key Points

• Statement I - Incorrect:

In learner-centered learning, the teacher does shift from a traditional knowledge transmitter to a facilitator, but the focus isn't solely on students' feelings. While creating a positive and supportive environment is important, the primary focus is on guiding students to explore, construct, and apply knowledge independently.

• Statement II - Correct:

Learner-centered learning emphasizes the importance of understanding the world from the students' perspective. This involves empathy, actively listening to students' experiences and viewpoints, and creating a safe space for them to express themselves freely.

Additional Information 

• Teacher-centered learning traditionally involves the teacher as the main source of knowledge and authority. Students are expected to passively receive information and demonstrate their understanding through assessments.
• While both approaches have their merits and drawbacks, learner-centered methods are increasingly embraced as they foster critical thinking, self-directed learning, and deeper understanding in students.

The correct answer from the options given is: (A), (B), and (C) Only

 

(A) Physical location:

• The setting or environment where communication occurs can significantly impact its meaning.
• For example, a conversation in a formal setting like a corporate boardroom may carry a different connotation than the same conversation occurring in a casual setting.

 

(B) Participants:

• The individuals involved in the communication process bring their own experiences, expectations, and cultural backgrounds, all of which influence the interpretation of the message.
• Understanding the relationship between participants (such as their power dynamic, familiarity, or roles) is crucial in determining meaning.

 

(C) Preceding events:

• What has happened before the communication takes place can shape the context and influence the interpretation of the message.
• Preceding events can establish a certain mood, expectation, or bias that affects how subsequent communication is perceived.

 

Additional Information

(D) Nonfunctional goals:

• While goals, including nonfunctional ones, can influence how a message is crafted and perceived, they are not considered a contextual factor that determines meaning in communication behavior.
• Nonfunctional goals refer to outcomes that aren't directly related to the task at hand but might influence behavior, such as seeking approval or asserting dominance. They are more about the underlying intentions rather than the context that shapes meaning.

( E) Absence of audience:

• The audience's presence or absence can affect how communication is delivered (e.g., public speaking versus a private conversation). However, it's not considered a primary contextual factor in determining the meaning of communication behavior.
• This option focuses on a particular scenario's impact (having no audience) rather than the broader context that contributes to the interpretation and understanding of the message.

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

Key Points

• Assertion (A) states that no single test can perfectly capture a student's abilities and skills. This is true. Tests are designed to assess specific knowledge or skills in a controlled environment, but they cannot comprehensively evaluate all aspects of a student's potential. Factors like creativity, critical thinking, problem-solving, and work ethic are not easily measured by traditional tests.
• Reason (R) explains that a test is just a "small sample" of a student's performance. This supports the assertion. A one-time test under specific conditions doesn't represent the full range of a student's knowledge and abilities over time and across different situations.

Therefore, both the assertion and the reason are true, and the reason accurately explains why the assertion is valid.

Calculation:

Let the two numbers be x and y.

x + y = 19 --- [1]

x - y = 7 --- [2]

By the method of elimination, we get

2x = 26

x = 26/2 = 13

Put x = 13 in eq [1], we get

13 + y = 19

y = 19 - 13

y = 6

Therefore, the two numbers are 13, 6

Sum of their squares = 13² + 6²

⇒ 169 + 36 = 205

Hence, 205 is the correct answer.

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

Key Points

• The passage clearly mentions that "Schools must move away from being centres of education alone," suggesting that they should serve additional functions beyond mere educational facilitation.
• It's therefore incorrect to claim that schools should only be centres of education (Statement I), as the author advocates a more comprehensive role for schools.
• According to the passage, the schools should also focus on uplifting and recognizing creativity, promoting new thinking, and encouraging skill development.
• As for Statement II, the passage puts forth that "all our aspirations as a society are tied to the capabilities of our youngsters, who form such a large part of our population."
• This clearly refutes the claim that youngsters form a minimal part of our population, indicating that they, in fact, comprise a considerable proportion.

Therefore, the correct option is 'Option 2'.

The correct answer is 'Value-based education'.

Key Points

• As per the text, it is clear that the author identifies a good, value-based education system necessary for shaping the young citizens into enlightened human beings.
• Such an education system has been deemed useful for nurturing a child's individuality and creativity and is envisaged as the key to building the nation of dreams.
• Parents and teachers are expected to helm this mission, promoting an integrated value system both at home and in school.
• An innovative curriculum and an overhauled examination system, which identifies and evaluates creativity and novel thinking instead of factual memorization, are also emphasized as facets of this process.
• Therefore, having more schools, democracy, or rapid urbanization isn't clearly correlated with building the nation of their dreams. Instead, quality education, imbued with values, and centered on creativity, is seen as the vital element.

Therefore, the correct answer is 'Option 2'.

The correct answer is '(C) & (E) Only'.

Key Points

• As per the text, the learning that young citizens receive between the ages of five and sixteen at home, in school, and in society shapes them into enlightened beings.
• The author emphasizes an integrated form of education, indicating the importance of learning received in various circumstances - at home, school, and society.
• The author also indicates the critical years for this development are between the ages of five and sixteen.
• Therefore, both Option C ('At home, in school and in society') and Option E ('Between the ages of five and sixteen') are correct.
• Additional Information:CopyCopy
• Options A, B, and D isolate a single aspect of a child's learning environment, contrary to the holistic approach outlined in the text.

Conclusion: Therefore, the correct option is 'Option C'.

The correct answer is 'Parents and Teachers'.

Key Points

• According to the text, it is clear that the author refers to both parents and teachers as the stakeholders needing to have an integrated mission.
• They are required to provide education with a good value system, both at home and in school.
• This integrated vision by parents and teachers plays a crucial role in shaping the youngsters into enlightened human beings.
• As per the passage, both parents and teachers are influential in this mission, not politicians, philanthropists, or businessmen.
• Additional Information:CopyCopy
• While the other options may play a supporting or instrumental role in education, they are not explicitly identified as carriers of this mission in the passage.

Conclusion: Therefore, the correct answer is 'Option 3'.

The correct answer is "(A), (B) & (D) Only"

Key Points

• The passage indicates that a good examination system should be able to recognize a child's creativity. This refers to the unique thoughts, ideas, strategies, and perspectives that each child brings to a learning environment, an aspect that an effective examination system should appreciate and consider.
• The passage also emphasizes the need to recognize a child's individuality. Each child is unique, with a distinct personality, learning style, pace of learning, and potential. Therefore, an effective examination system needs to cater to these variances and acknowledge a child's distinctive abilities.
• The passage underscores the need for an examination system that encourages new thinking. This means that exams should not just test memory skills or the acquisition of factual information, but should also assess the child's ability to think critically, innovatively, and independently.
• The passage directly contradicts option (C), stating that the examination system should move away from just evaluating the memorization of facts, hence, it does not advocate for encouraging rote learning.

Therefore, the correct option is "(A), (B) & (D) Only".
