UGC NET Paper 1: Held on 13th Mar 2023 Shift 1 (Previous Year Paper)

Given:

Number of tickets of movie B sold in Hyderabad: 17,000

Calculation:

Total number of tickets of movie B = Number of tickets of movie B in Delhi + Number of tickets of movie B in Mumbai + Number of tickets of movie B in Kolkata + Number of tickets of movie B in Chennai + Number of tickets of movie B in Hyderabad + Number of tickets of movie B in Chandigarh

= 7500 + 9500 + 12000 + 10500 + 17000 + 13500

= 70000

Percentage = (Number of tickets of movie B sold in Hyderabad / Total number of tickets of movie B sold in all cities) × 100

⇒ (17,000 ÷ 70,000) × 100

⇒ 24.28% ≈ 24%

∴ The number of tickets of movie B sold in Hyderabad was approximately 24% of the total number of tickets of the same movie sold in all the cities together.

Given:

Number of tickets of movie D sold in Kolkata = 10,500

Number of tickets of movie B sold in Chandigarh = 13,500

Calculation:

Difference = Number of tickets of movie B in Chandigarh - Number of tickets of movie D in Kolkata

⇒ 13,500 - 10,500 = 3,000

Percentage Difference = (Difference / Number of tickets of movie B in Chandigarh) × 100

⇒ (3,000 ÷ 13,500) × 100 ≈ 22.22%

∴ The number of tickets of movie D sold in Kolkata is approximately 22% less than the number of tickets of movie B sold in Chandigarh.

Concept used:

Average = Sum of observation / Number of observations

Calculation:

Total number of tickets of movie C sold = 17,500 + 10,500 + 9,500 + 16,000 + 13,000 + 10,000 = 76,500

Number of cities = 6

Average number of tickets of movie C sold = Total number of tickets of movie C sold ÷ Number of cities

⇒ 76,500 ÷ 6 = 12,750

∴ The average number of tickets of movie C sold in all the six cities together is 12,750.

Given:

Number of tickets of movie E sold in Chennai = 17,000

Number of tickets of movie A sold in Mumbai = 8,500

Calculation:

Percentage = (Number of tickets of movie E sold in Chennai / Number of tickets of movie A sold in Mumbai) × 100

⇒ (17,000 ÷ 8,500) × 100 = 200%

∴ The number of tickets of movie E sold in Chennai is indeed 200% of the number of tickets of movie A sold in Mumbai.

Calculation:

Ticket sold in,

Delhi = 10,000 + 7,500 + 17,500 + 13,000 + 9,000 = 57,000

Mumbai = 8,500 + 9,500 + 10,500 + 12,500 + 14,000 = 55,000

Kolkata = 16,000 + 12,000 + 9,500 + 10,500 + 8,500 = 56,500

Chennai = 9,000 + 10,500 + 16,000 + 14,000 + 17,000 = 66,500

Hyderabad = 8,000 + 17,000 + 13,000 + 14,500 + 11,000 = 63,500

Chandigarh = 7,500 + 13,500 + 10,000 + 17,500 + 13,000 = 61,500

∴ The second minimum value is in the city Kolkata.

Key Points 

Statement I: Adolescence period is the transitional period of growth and development between childhood and adulthood.

• Adolescence is commonly defined as the period between childhood and adulthood, typically starting with the onset of puberty and ending with the attainment of full physical and psychological maturity.
• It is a time of significant physical, cognitive, and socio-emotional changes as individuals progress from childhood to adulthood.

This statement is true. 

Statement II: Adolescence is a period of emotional stability and great relief.

• Adolescence is often characterized by increased emotional intensity, mood swings, and the experience of various challenges and stressors.
• It is a time of exploration, identity formation, and sometimes turbulent emotions.
• While individuals may experience periods of emotional stability, it is not accurate to generalize adolescence as a period of overall emotional stability and great relief.

This statement is false. 

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

Key PointsLearning: 

• Learning is the process of acquiring new knowledge, skills, values, attitudes, and preferences.
• It is a lifelong process that begins at birth and continues throughout our lives.
• Learning can happen through formal education, informal experiences, and even through interactions with our environment.

Characteristics of learning:

A. Learning is a temporary change in behavior:

• This statement is not accurate.
• Learning involves a relatively permanent change in behavior, knowledge, or understanding. It is not merely a temporary alteration but results in a lasting impact on an individual's behavior or mental processes.
• B. Learning ends up to puberty: This statement is incorrect.
• Learning is a lifelong process that continues beyond puberty. Individuals continue to learn and acquire new knowledge and skills throughout their lives, regardless of their age or developmental stage.
• C. Learning is active and creative: This statement is correct.
• ​Learning is an active process that involves the engagement and participation of the learner. It is not a passive reception of information but rather an active construction of knowledge and understanding. Learners actively make connections, apply concepts, and engage in creative problem-solving and critical thinking.
• D. Learning is goal-directed: This statement is correct.
• ​Learning is often driven by goals or objectives. It involves purposeful and intentional efforts to acquire new knowledge, develop skills, or achieve specific outcomes. Goals provide direction and focus to the learning process.
• E. Learning is motivated by adjustment: This statement is correct.
• ​ Learning is often motivated by the need to adapt, adjust, or respond to changes in the environment or to personal needs and aspirations. Motivation plays a significant role in learning, as individuals are driven to acquire knowledge and skills that help them navigate and succeed in their surroundings.

 

Therefore, the correct answer is option 1) C, D, and E only, as these statements accurately describe the characteristics of learning.

Key Points

The cognitive domain of Bloom's taxonomy includes the following categories:

• Knowledge: 
• ​This is the lowest level of the cognitive domain and involves the recall of facts, terms, and concepts.
• Comprehension: 
• This level involves understanding the meaning of information and being able to explain it in one's own words.
• Application: 
• This level involves using information in new situations.
• Analysis: 
• This level involves breaking down information into its component parts and understanding how they relate to each other.
• Evaluation: 
• This level involves making judgments about the value of information or ideas.
• Creation: 
• ​This level involves creating new products or ideas.

The categories of Receiving, Valuing, and Organization are part of the affective domain of Bloom's taxonomy.

Therefore, the correct answer is 1, C and D only.

Key PointsSnowball sampling: 

• Snowball sampling is a non-probability sampling technique commonly used in research studies, especially when studying populations that are difficult to access or have specific characteristics.
• In snowball sampling, initial participants who meet certain criteria or have specific characteristics are identified and recruited.
• These participants are then asked to refer or nominate other individuals who also meet the criteria or share the characteristics of interest.
• A major advantage of snowball sampling is that it allows the research to focus only on people of particular interest.
• By leveraging the social networks and connections of the initial participants, the researcher can identify and recruit individuals who are more likely to possess the desired characteristics or have knowledge and experiences relevant to the research study.
• This sampling method is particularly useful when studying populations that are rare, hidden, or hard to reach, such as marginalized communities, specific subcultures, or individuals with specific experiences or expertise.
• It helps researchers access and gather data from individuals who may not be easily identifiable or accessible through traditional sampling methods.

 

Therefore, the correct answer is option 3) people of particular interest.

Key Points 

Cronbach's alpha is used to assess an instrument's reliability.

Reliability:

• Reliability is the consistency of a measurement.
• It measures how well an instrument measures the same thing over time and across different people.
• A reliable instrument will produce consistent results when it is administered to the same people on different occasions.
• Cronbach's alpha is a coefficient of reliability that is calculated from the correlations between the items on an instrument.
• A high alpha coefficient indicates that the items on the instrument are highly correlated and therefore measure the same thing.

Validity:

• Validity is the extent to which an instrument measures what it is supposed to measure.
• It is a broader concept than reliability and includes aspects such as content validity, construct validity, and criterion validity.

Randomness:

• Randomness is the absence of a pattern in a sequence of events.
• It is a measure of how likely it is that the next event in a sequence will be the same as the previous event.

Longevity:

• Longevity is the length of time that an instrument remains useful.
• It is a measure of how long the instrument will continue to produce reliable and valid results.

 

Therefore, the correct answer is 2, Reliability.

Key PointsCriterion variable: 

• In correlational research, the focus is on exploring the relationship between two or more variables.
• The dependent variable is the variable that is being measured or observed and is expected to change in response to changes in the independent variable(s).
• It is often referred to as the criterion variable because it is the variable against which the relationship or correlation with other variables is assessed.

Additional Information

• Predictor variable: The predictor variable refers to the independent variable(s) in correlational research. It is the variable that is hypothesized to predict or influence changes in the dependent variable. In other words, it is the variable that is being manipulated or controlled by the researcher to observe its relationship with the dependent variable.
• Critical variable: The term "critical variable" is not a commonly used term in the context of correlational research. It does not specifically denote any specific variable or concept in this research design.
• Extraneous variable: An extraneous variable is a variable that is not the main focus of the study but may still have an influence on the relationship between the independent and dependent variables. It is a variable that the researcher aims to control or account for to ensure that it does not confound or distort the observed relationship. In correlational research, the focus is on assessing the relationship between the independent and dependent variables, so controlling for extraneous variables becomes important to establish a clearer understanding of the relationship.

In the given question, the term "dependent variable" is specifically being asked about, and it is commonly referred to as the criterion variable in correlational research.

Therefore, the correct answer remains option 3) Criterion variable.

Key Points 

• Statement A is true because qualitative research is a valuable tool for understanding human behavior and social phenomena. It can be used to explore people's experiences, beliefs, and motivations in depth, and to gain insights that would not be possible with quantitative research.
• Statement D is true because qualitative research has many different approaches, such as ethnography, grounded theory, and phenomenology. Each approach has its own strengths and weaknesses, and the best approach for a particular research project will depend on the specific research questions being asked.
• Statement E is true because within qualitative research, different schools of research perspectives have emerged. These schools of thought differ in their philosophical underpinnings, their methods, and their focus. For example, some schools of thought emphasize the importance of understanding the participant's perspective, while others emphasize the importance of analyzing the social context in which the participant is embedded.
• Statement B is false because quantitative studies can be a valuable tool for understanding social phenomena. They can be used to test hypotheses, to make predictions, and to measure the impact of interventions. However, quantitative studies are not always appropriate for understanding complex social phenomena.
• Statement C is false because qualitative and quantitative research can be complementary. In some cases, it can be helpful to use both types of research to gain a more complete understanding of a social phenomenon.

 

Therefore, the correct answer is 4, A, D and E only.

Key Points 

Statement I: In quantitative research, descriptive and inferential statistics are employed.

• . Quantitative research involves the collection and analysis of numerical data, and descriptive statistics are used to summarize and describe the collected data,
• while inferential statistics are used to draw conclusions and make inferences about a larger population based on the collected sample data.

This statement is correct

Statement II: In qualitative research, the scope of enquiry includes broad thematic concerns.

• Qualitative research focuses on understanding and exploring complex phenomena, often using open-ended questions and in-depth interviews or observations.
• The scope of enquiry in qualitative research is broad and encompasses various themes and perspectives, allowing for a rich and nuanced understanding of the research topic.

This statement is also correct.

Therefore, the most appropriate answer is option 1) Both Statement I and Statement II are correct.

Key Points Conventional media:

• Conventional media such as newspapers, radio, and television lack face-to-face interaction.
• These forms of media are primarily one-way communication channels where the audience receives information or content without direct personal interaction with the creators or presenters.
• Face-to-face interaction involves direct interpersonal communication, including nonverbal cues, real-time feedback, and the ability to engage in immediate conversation.
• Newspapers, radio, and television provide content and information to a wide audience, but they do not allow for immediate or direct interaction between the audience and the creators or presenters of the media.
• They typically rely on broadcasting or publishing pre-recorded or pre-written content to be consumed by the audience.
• While conventional media may lack face-to-face interaction, they serve other important purposes such as providing news, entertainment, and educational content to a large audience.
• However, compared to face-to-face interaction, they have limitations in terms of immediate feedback, personalized interaction, and the ability to tailor content to individual needs or preferences.

 

Therefore, the (correct answer is 3) Face-to-face interaction.

Key Points Transmission models of communication:

• The transmission models of communication, also known as the linear models of communication,
• conceptualize communication as a linear process where information is transmitted from a sender to a receiver through a chosen channel.
• These models emphasize the flow of information and the role of the sender and receiver in the communication process.
• The key components of the transmission models of communication include:
• Sender: The sender is the individual or entity who initiates the communication process by encoding a message. The sender's goal is to convey information or a message to the receiver.
• Message: The message is the information or content being transmitted by the sender. It can be in various forms, such as spoken words, written text, visual images, or any other symbolic representation.
• Channel: The channel refers to the medium through which the message is transmitted from the sender to the receiver. It can be a face-to-face conversation, written letter, telephone call, email, or any other communication medium.
• Receiver: The receiver is the individual or entity who receives the message from the sender. Their role is to decode the message, extracting meaning from it.
• Noise: Noise refers to any interference or factors that can disrupt or distort the transmission or reception of the message. It can be physical noise, such as loud sounds, or psychological noise, such as distractions or preconceived notions.
• In the transmission models, communication is viewed as a one-way process, focusing on the sender's role in encoding and transmitting the message and the receiver's role in decoding and understanding the message.
• Feedback is often not explicitly addressed in these models, as they primarily emphasize the linear flow of information.

Hence, (option 2) Instrumental act best aligns with this understanding of communication as an instrumental process where the primary goal is to transmit information or a message from the sender to the receiver.

Additional Information

• Intra-personal process: Intra-personal process refers to communication that occurs within an individual, involving internal thoughts, self-reflection, and personal decision-making. It focuses on the individual's internal communication processes rather than communication between people. The transmission models of communication do not specifically address the intra-personal process, as they primarily focus on the external transmission of messages between a sender and a receiver.
• Language act: Language act refers to communication as an act of using language to convey meaning and express thoughts, ideas, or information. While language is an essential component of communication in general, the transmission models of communication do not solely emphasize language but consider broader aspects such as encoding, transmission, and decoding of messages.
• Ritualistic process: The ritualistic process refers to communication as a symbolic and cultural ritual that serves to establish and maintain social norms, values, and identity. It focuses on the symbolic and cultural aspects of communication, highlighting how communication can reinforce social cohesion and group identity. However, the transmission models of communication do not specifically address the ritualistic process as their main focus is on the transmission of messages and the flow of information.

Key PointsHoward Rheingold: 

• Howard Rheingold, a renowned author and scholar, coined the term 'bloodless technological ritual' in his book "The Virtual Community: Homesteading on the Electronic Frontier."
• In this book, Rheingold explores the emergence and dynamics of online communities and the social interactions that take place in virtual spaces.
• Rheingold suggests that internet communication, particularly within online communities, can be seen as a 'bloodless technological ritual.'
• This phrase emphasizes several key aspects:
• Symbolic and Cultural Nature: Rheingold highlights that online interactions and communication in virtual spaces involve the creation of symbolic meanings and cultural practices. Participants in online communities engage in rituals, establish norms, and develop shared understandings through their communication.
• Lack of Physical Presence: The term 'bloodless' indicates the absence of physical presence in internet communication. Unlike face-to-face communication, where physical presence and bodily cues play a significant role, internet communication relies on digital technologies and mediated interactions.
• Technological Mediation: Rheingold acknowledges that the internet and digital technologies act as mediators in these communication rituals. Participants utilize various online platforms, tools, and technologies to engage in virtual communication, forming connections and communities across physical distances.
• Ritualistic Elements: The term 'ritual' signifies the repetitive and structured nature of online communication. Within online communities, participants engage in specific practices, follow established patterns, and adhere to norms and rituals that contribute to a sense of belonging and social cohesion.

1. Overall, Rheingold's characterization of internet communication as a 'bloodless technological ritual' captures the unique qualities and dynamics of communication in virtual spaces. It highlights the symbolic, cultural, and ritualistic dimensions that shape online interactions and contribute to the formation and maintenance of online communities.

 

Therefore, the correct answer is option 4) Internet communication.

Key Points 

The correct answer is 1, Both Statement I and Statement II are correct.

Statement I: For scholar like Guy Debord, modern media are agents of political power as well as urbanisation.

• Guy Debord, a French theorist, argued that modern media are agents of political power and urbanisation.
• He believed that the media create a "spectacle" that distracts people from reality and reinforces the status quo.

Statement I is correct 

Statement II: Modern media make people accept inequality and hierarchy, say critics.

• Critics have argued that modern media make people accept inequality and hierarchy.
• They argue that the media often portray the rich and powerful in a positive light, while the poor and marginalized are often portrayed in a negative light.
• This can lead people to believe that inequality is natural and inevitable.

Statement II is also correct 

Here are some additional details about Guy Debord and his theory of the spectacle:

• Debord was a member of the Situationist International, a group of radical artists and theorists who critiqued modern society.
• Debord's book, The Society of the Spectacle, is a seminal work of critical theory.
• The spectacle is a term that Debord used to describe the way that modern media create a false reality that distracts people from the real world.
• Debord argued that the spectacle is a tool of political power and that it serves to reinforce the status quo.
• Debord's theory of the spectacle has been influential in a number of fields, including critical theory, media studies, and cultural studies.

Key Points Statement I: For Derrida, the meaning of a signifier in communication will always be different in its meaning at the point of consumption from the point of production.

• Jacques Derrida, a French philosopher, argued that the meaning of a signifier is always deferred.
• This means that the meaning of a word or sign is not fixed, but is always in flux.
• It is constantly being reinterpreted and renegotiated by different people in different contexts.

 

Statement I is correct

Statement II: It is therefore stated that the original context of meaning cannot be reproduced.

• Derrida argued that the original context of meaning cannot be reproduced.
• This is because the meaning of a word or sign is always dependent on the context in which it is used.
• When a word or sign is used in a new context, its meaning is inevitably changed.

Statement II is also correct

Therefore, both statements are correct.

Here are some additional details about Jacques Derrida and his theory of différance:

• Derrida coined the term "différance" to describe the way that meaning is always deferred in language.
• Différance is a neologism that combines the French words "différence" (difference) and "différer" (to defer).
• Derrida argued that différance is the condition of possibility for meaning in language.
• Différance means that the meaning of a word or sign is always in flux. It is constantly being reinterpreted and renegotiated by different people in different contexts.
• Derrida's theory of différance has been influential in a number of fields, including philosophy, literary theory, and cultural studies.

The correct answer is 1, Both Statement I and Statement II are correct.

Given: 3, 6, 11, 20, 37, 70, 135, 264, ?

The required logic is shown below;

 

Hence, the missing term will be "521".

Shortcut Trick

Sum of ages today = 90 years. Sum when it doubles = 180 years.

Total age increase = 180 − 90 = 90 years. Since there are 3 members, each ages by 90 ÷ 3 = 30 years.

After 30 years, Son + 30 = 0.5 × (Father + 30). Since Father = 6 × Son, we get:

Son + 30 = 0.5 × (6Son + 30) ⇒ Son + 30 = 3Son + 15 ⇒ 2Son = 15 ⇒ Son = 7.5 years.

Father = 6 × 7.5 = 45 years. Mother = 90 − (45 + 7.5) = 37.5 years.

∴ The correct answer is 37.5 years.

Alternate Method

Given: Present sum (F + M + S) = 90. F = 6S.

⇒ Let n be the years passed. 3n = 180 − 90 ⇒ n = 30 years.

⇒ Future age of Son = S + 30. Future age of Father = F + 30.

⇒ Condition: (S + 30) = (F + 30) ÷ 2

⇒ 2(S + 30) = (6S + 30)

⇒ 2S + 60 = 6S + 30

⇒ 4S = 30 ⇒ S = 7.5 years.

⇒ Father's age (F) = 6 × 7.5 = 45 years.

⇒ Mother's age (M) = 90 − (45 + 7.5) = 37.5 years.

∴ The correct answer is 37.5 years.

Additional Information

Sum of Ages over Time

If there are k members in a group, after n years, the sum of their ages increases by n × k.

Ratio of Ages

The difference between the ages of two people remains constant regardless of how many years pass.

Calculation:

Let's assume that box B has x number of apples, then box A have (x + \(\frac{1}{5} x\)) no of apples,

According to the question,

⇒ (x + \(\frac{1}{5} x\)) - x = 8

⇒ x = 40

So, the number of apples in box A = (40 + \(\frac{1}{5} \times 40\)) = 48

∴ The correct answer is 48

The given code can be represented as;

From the above figure, it is clear that the code for 'tea' and 'dense' are '7' and '9'.

Hence, the correct answer is '7' and '9'.

Key Points

The fallacy committed in the above argument is affirming the consequent.

Affirming the consequent:

• Affirming the consequent is a formal fallacy that occurs when the conclusion of an implication is affirmed, and the implication is then used to infer the antecedent.
• In this case, the implication is "If you read Professor Harry's book, you should be able to recognise and successfully attack fallacious reasoning."
• The conclusion of the implication is "you are able to do that." The person making the argument then affirms the conclusion, saying "you are able to do that."
• They then infer the antecedent by saying "Therefore, you must have read Professor Harry's book."
• However, this is a fallacy because the conclusion of an implication does not necessarily imply the antecedent. Just because you are able to recognize and successfully attack fallacious reasoning does not mean that you have read Professor Harry's book. There are other ways to learn how to do this.

Therefore, the correct answer is 2, Affirming the consequent.

Additional Information Denying the antecedent:

• This fallacy occurs when an argument assumes that if the antecedent of a conditional statement is false, then the consequent must also be false. The argument in the given statement does not commit the fallacy of denying the antecedent because it does not state that if you did not read Professor Harry's book (antecedent), then you cannot recognize and successfully attack fallacious reasoning (consequent).

Existentialist fallacy:

• The existentialist fallacy occurs when a universal claim is made based on an existential premise. The given statement does not commit this fallacy because it does not make a universal claim based on an existential premise.

Undistributed middle:

• The fallacy of undistributed middle occurs when a middle term in a categorical syllogism is not distributed (referring to all class members) in at least one of the premises. The given statement does not involve a categorical syllogism, so it does not commit the fallacy of undistributed middle.

Key Points 

The fallacy committed in the statement "All things are non-eternal because they are knowable" is Anupasamhari.

• Anupasamhari:
• Anupasamhari is a fallacy of the irregular middle.
• It occurs when the middle term is all-inclusive and leaves nothing by the way of sapaksa or vipaksa.
• In this case**, the middle term, "knowable," is all-inclusive,** meaning that it applies to everything.
• This means that the conclusion, "all things are non-eternal," cannot be inferred from the premises,
• because there is no vipaksa, or counterexample, to show that the middle term does not apply to everything.
• The other three fallacies, Viruddha, Sadharana, and Asadharana, are all fallacies of the irregular hetu.
• Viruddha occurs when the middle term is contradicted by the vipaksa.
• Sadharana occurs when the middle term is present in both the sapaksa and the vipaksa.
• Asadharana occurs when the middle term is too narrow, and is only present in the subject term.
• In this case, the fallacy of Anupasamhari is committed because the middle term, "knowable," is all-inclusive, meaning that it applies to everything.
• This means that the conclusion, "all things are non-eternal," cannot be inferred from the premises,
• because there is no vipaksa, or counterexample, to show that the middle term does not apply to everything.

Key Points 

Statement I: Wi-Fi, a wireless network protocol, is an acronym for Wireless Firewire.

• Wi-Fi is not an acronym for Wireless Firewire.
• Wi-Fi is actually a portmanteau of "Wireless Fidelity".
• The term was coined by the marketing firm Interbrand in 1999 to create a more user-friendly name for the IEEE 802.11b wireless networking standard.

This statement is false

Statement II: (21.125)10 = (10101.001)2.

• The given equation states that the decimal number 21.125 is equal to the binary number 10101.001.
• In binary notation, each digit represents a power of 2, with the rightmost digit representing 2^0, the next digit representing 2^1, and so on.
• By converting the decimal number 21.125 to binary, we get 10101.001.

This statement is true. 

Therefore, the correct answer is option 4) Statement I is false but Statement II is true.

Key Points

 A: Search engines are also known as web browsers.

• Search engines are not the same as web browsers.
• A search engine is a software system that allows users to search for information on the internet by entering keywords or phrases,
• while a web browser is a software application used to access and view websites.
• Examples of search engines include Google, Bing, and Yahoo, while popular web browsers include Google Chrome, Mozilla Firefox, and Apple Safari.

This is not True.

Statement B: Apple's web browser is called as 'Chrome'

• Apple's web browser is not called "Chrome."
• Google Chrome is a web browser developed by Google, while Apple's web browser is called Safari.
• Safari is the default web browser on Apple devices such as iPhones, iPads, and Mac computers.

This is not True.

Statement C:C. Micro-blogging is the practice of posting small pieces of content on the Internet systems such as Twitter.

• Micro-blogging refers to the practice of posting small pieces of content on the internet systems such as Twitter.
• Micro-blogging platforms allow users to share brief updates, thoughts, or messages in the form of short posts or tweets.
• Twitter is one of the most popular micro-blogging platforms where users can post and interact with content in a concise manner.

This is True.

Therefore, the correct answer is option 4) C only.

Key Points Asynchronous communication:

• Asynchronous communication is a type of communication where the sender and receiver do not need to be present at the same time.
• This means that the sender can send a message, and the receiver can read it at their own convenience.
• Forums and email are two examples of asynchronous communication technologies.
• When you post a message on a forum, the other members of the forum can read it at their own convenience.
• Similarly, when you send an email, the recipient can read it when they have time.
• Video conferencing and instant messaging are two examples of synchronous communication technologies.
• When you use video conferencing, you are able to see and talk to the other person in real time.
• Similarly, when you use instant messaging, you are able to send messages to the other person in real-time.

 

Therefore, the only digital communication technologies that use asynchronous communication are forums and email.

Video conferencing and instant messaging are both synchronous communication technologies.

The correct answer is 3, A and C only.

Key Points Statement I: Grid-connected photovoltaic system supplements the grid power during the daytime.

• Grid-connected photovoltaic (PV) systems, also known as solar power systems, can indeed supplement the grid power during the daytime.
• These systems generate electricity from solar panels and feed it into the grid, thus adding to the overall power supply.
• This is particularly beneficial during daylight hours when solar energy production is at its peak.

Statement I is correct.

Statement II: Grid-connected photovoltaic system does not require additional equipment to control voltage etc.

• Grid-connected photovoltaic systems usually require additional equipment to control various aspects, including voltage and power flow.
• These additional components are necessary to ensure solar power's safe and efficient integration into the grid.
• Examples of such equipment include inverters, which convert the DC electricity generated by solar panels into AC electricity suitable for the grid, and grid-tie inverters that synchronize the solar power system with the grid's voltage and frequency.

Statement II is incorrect. 

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

Key Points Statement I: Deemed Universities can frame their own guidelines regarding admission and fees and can grant degrees.

• Deemed universities are granted autonomy by the University Grants Commission (UGC) to frame their own guidelines regarding admission and fees and to grant degrees.
• This means they are not bound by the same rules and regulations as other universities in India.
• They can set their own admission criteria, decide their fees, and award their degrees.
• This autonomy is granted to deemed universities because they are considered to be of a high standard.
• They are expected to have high-quality faculty, good infrastructure, and a strong research record.
• By granting them autonomy, the UGC encourages them to continue innovating and improving their standards.

Hence this statement is correct.

Statement II: The Governor of the state is the chancellor of deemed universities.

• The chancellor of a deemed university is the highest-ranking official in the university.
• They are responsible for the overall governance of the university, and they have the power to appoint and dismiss the vice-chancellor.
• The Governor of the state does not appoint the chancellor of a deemed university. Instead, they are appointed by the founder of the university or by the governing body of the university.
• The state's governor does not have any role in appointing the chancellor of a deemed university.

This statement is not correct

Hence, the correct answer is 3; statement I is true, but Statement II is false.

Given:

The sum of the squares of 3 consecutive odd numbers is 2531.

Calculation:

According to the given information, the sum of the squares of the three consecutive odd numbers is 2531:

⇒ (2n - 1)² + (2n + 1)² + (2n + 3)²  = 2531

Simplifying the equation:

⇒ 4n² - 4n + 1 + 4n² + 4n + 1 + 4n² + 12n + 9 = 2531

⇒ 12n² + 12n + 11 = 2531

⇒ 12n² + 12n - 2520 = 0

Dividing both sides of the equation by 12:

⇒ n² + n - 210 = 0

Now, we can factorize the quadratic equation:

⇒ (n + 15)(n - 14) = 0

So, we have two possible solutions for n: n = -15 and n = 14.

However, n represents an integer, so the valid solution is n = 14.

Now, we can find the three consecutive odd numbers:

First odd number: 2n - 1 = 2(14) - 1 = 27

Second odd number: 2n + 1 = 2(14) + 1 = 29

Third odd number: 2n + 3 = 2(14) + 3 = 31

Now we can check if these numbers are prime:

27 is not prime (divisible by 3 and 9) 29 is prime 31 is prime

Therefore, out of the three consecutive odd numbers, two of them (29 and 31) are prime numbers.

So the answer is 2

Key Points 

The fallacy committed in the statement "No one has ever proven that God exists. Therefore God does not exist" is appeal to ignorance.

Appeal to ignorance:

• Appeal to ignorance is a logical fallacy that occurs when someone argues that a proposition is true because it has not been proven false.
• In this case, the person is arguing that God does not exist because no one has ever proven that God exists.
• However, this is a fallacy because the lack of evidence for something does not mean that the thing does not exist.
• There are many things that we do not know, and it is possible that God exists even though we have not yet found proof of his existence.

Here are some other examples of the appeal to ignorance fallacy:

• "There is no scientific evidence that ghosts exist, so they must not exist."
• "There is no proof that Bigfoot exists, so he must not exist."
• "There is no proof that aliens have visited Earth, so they must not have visited Earth."

Additional Information

• Ad hominem is a logical fallacy that occurs when someone attacks the person making an argument instead of the argument itself. In this case, the person is attacking the person who is arguing that God does not exist, instead of attacking the argument itself. This is a fallacy because it does not address the merits of the argument.
• Hasty generalization is a logical fallacy that occurs when someone makes a generalization based on a small sample size. In this case, the person is making a generalization about the existence of God based on the fact that no one has ever proven that God exists. However, this is a fallacy because the sample size is too small. There are many people in the world, and it is possible that God exists even though no one has yet proven it.
• Slippery slope is a logical fallacy that occurs when someone argues that a small first step will inevitably lead to a larger, more negative consequence. In this case, the person is arguing that the belief in God will inevitably lead to theocracy. However, this is a fallacy because there is no evidence to support this claim. It is possible to believe in God without believing in theocracy.

Key PointsNitrous oxide (N2O): 

• Nitrous oxide (N2O) is a greenhouse gas that is produced by a variety of sources, including agriculture, combustion of fossil fuels, and industrial processes.
• It is a potent greenhouse gas, and it is estimated to have a global warming potential that is 300 times greater than that of carbon dioxide.

The other oxides of nitrogen, NO2 (nitrogen dioxide), NO (nitric oxide), and N2O3 (nitric trioxide), are not greenhouse gases.

• NO2 is a pollutant that can contribute to smog and acid rain, but it does not have a significant greenhouse effect.
• NO is a relatively inert gas, and it does not contribute to the greenhouse effect.
• N2O3 is a very unstable gas, and it does not exist in the atmosphere for very long.

 

Therefore, N2O nitrous oxide is the only oxide of nitrogen that is a greenhouse gas.

Key Points Particulate matter (PM):

• Particulate matter (PM) is a mixture of solid particles and liquid droplets found in the air. T
• hese particles come in a variety of sizes, and they can be made up of a variety of materials.
• PM can be harmful to human health, and it can also contribute to climate change.

Respirable Suspended Particulate Matter (RSPM):

• Respirable Suspended Particulate Matter (RSPM)s a term that is used to refer to all particles that are small enough to be inhaled.
• This includes PM10, as well as smaller particles such as PM2.5 and PM1.
• PM10 is the largest of these particles, and it is composed of particles that are 10 micrometres or less in diameter.
• PM10 can cause a number of health problems, including respiratory infections, heart disease, and cancer.
• It can also aggravate asthma and other respiratory conditions. PM10 can also contribute to climate change by absorbing sunlight and trapping heat in the atmosphere.

There are a number of things that can be done to reduce PM10 levels, including:

• Using cleaner burning fuels
• Reducing emissions from vehicles
• Controlling dust from construction sites
• Planting trees

 

PM10  type is also commonly known as Respirable Suspended Particulate Matter (RSPM).

Key Points

• Statements A and B are logically equivalent because they both say that there is no overlap between the set of professors and the set of non-competent scholars.
• Statements B and D are logically equivalent because they both say that if a person is a non-competent scholar, then they cannot be a professor.
• Statement C is not logically equivalent to any of the other statements because it says that there is no overlap between the set of competent scholars and the set of professors. However, it is possible for a person to be a competent scholar and not be a professor.

Therefore, the correct answer is 4, A, B and D only.

Here is a table that summarizes the logical equivalence of the four statements:

Key Points 

Statement A: Different header and footer for the last page of a section can be set in MS-Word.

• This statement is incorrect. In MS-Word, it is not possible to set a different header and footer specifically for the last page of a section.
• The header and footer in MS-Word remain consistent throughout a section unless manually changed.

Statement B: The ability to combine names and addresses with a standard document and send the same letter to different persons is called Mail Merge.

• This statement is correct. Mail Merge is a feature in MS-Word that allows users to create personalized letters or documents by merging a standard document template with a data source that contains names, addresses, or other information.
• This enables the creation of multiple customized documents for different recipients.

Statement C: Gutter Margin is the margin that is added to the binding side of a page when printing.

• This statement is correct**. In MS-Word, the gutter margin is an additional margin that is added to the inner or binding side of a page when printing documents that will be bound togethe**r, such as booklets or brochures.
• It provides extra space to accommodate the binding and prevents content from being obscured.

 

Therefore, the correct answer is option 3) B and C only.

Key Points M. N. Srinivas:

• M. N. Srinivas was a renowned sociologist who was appointed as the chairman of the UGC Review Committee for Sociology in 1961.
• The committee was tasked with reviewing the state of sociology education in India and making recommendations for its improvement.
• The committee's report, which was published in 1964, was a landmark document that had a profound impact on the development of sociology in India.
• The report made a number of recommendations, including the establishment of more sociology departments, the improvement of the quality of teaching and research, and the development of a national curriculum for sociology.
• Srinivas's chairmanship of the committee was a major achievement, and it helped to solidify his reputation as one of the most influential sociologists in India.

 

Therefore, the correct answer is 2, M. N. Srinivas.

Key Points Statement I: An operating system controls peripherals, allocates memory and organizes data into fields and records.

• An operating system manages computer resources, such as memory allocation, processor scheduling, and providing a user interface.
• However, it does not explicitly control peripherals or organize data into fields and records.
• Database man-organizing stems, or software applications typically organise data into fields and records, while device drivers often take peripheral control.

Statement II: An operating system controls the processor and peripherals, and allows the user to connect to the Internet.

• While an operating system provides the necessary functionality for connecting to the internet, it does not solely control the processor and peripherals.
• The central processing unit (CPU) typically manages the processor control, while peripherals often have their own control mechanisms or are managed through device drivers.

 

Therefore, both Statement I and Statement II are false.

Key Points

 The answer is 2, is the pollution of the water body.

Thermal pollution:

• Thermal pollution is the rise or fall in the temperature of a natural body of water caused by human influence.
• It is a type of water pollution that can have a significant impact on the ecosystem of the affected water body.

Thermal pollution can be caused by a number of activities, including:

• The discharge of hot water from power plants and industrial facilities.
• The use of water for cooling in industrial processes.
• The release of warm water from reservoirs.

Thermal pollution can have a number of negative effects on the ecosystem of a water body, including:

• The death of fish and other aquatic organisms.
• The disruption of the food chain.
• The growth of algae and other plants.
• The degradation of water quality.

Thermal pollution is a serious problem that can have a significant impact on the environment. It is important to take steps to reduce and prevent thermal pollution in order to protect our water resources.

Key Points 

Statement A: All physicists are outstanding teachers.

• This statement is a universal statement, which means that it applies to all physicists.
• If this statement is true, then every single physicist must be an outstanding teacher.
• However, if there are even one or two physicists who are not outstanding teachers, then this statement must be false.

Statement B: No physicists are outstanding teachers. 

• This statement is also a universal statement, but it is the negation of Statement A.
• If Statement A is true, then Statement B must be false.
• However, if Statement A is false, then Statement B could be true.
• For example, if there are no physicists at all, then it is true that no physicists are outstanding teachers.

Statement C: Some physicists are outstanding teachers.

• This statement is an existential statement, which means that it applies to at least one physicist.
• This statement does not say that all physicists are outstanding teachers, just that some of them are.
• Therefore, this statement could be true even if there are also some physicists who are not outstanding teachers.

Statement D: Some physicists are not outstanding teachers. 

• This statement is the negation of Statement C.
• It means that there are at least one or two physicists who are not outstanding teachers.
• This statement could be true even if there are also some physicists who are outstanding teachers.

As you can see, Statements A and B are negations of each other. This means that if one statement is true, the other must be false. However, both statements can be false if there are no physicists at all.

Statements C and D are not negations of each other. This means that it is possible for both statements to be true.

For example, it is possible that some physicists are outstanding teachers, while others are not.

Therefore, the correct answer is 1, A and B only.

Key Points 

Statement I: Formaldehyde, which is widely used in wood products and fabrics, is indeed a very strong allergen.

• It is a volatile organic compound (VOC) that can cause allergic reactions and sensitization in individuals who are exposed to it.
• Formaldehyde can be emitted from various sources such as furniture, flooring, cabinets, and clothing, and prolonged exposure to high levels of formaldehyde can be detrimental to health.

Statement II: Formaldehyde concentrations in indoor air can indeed be thousands of times higher than outdoor air.

• This is mainly because formaldehyde can be released from indoor sources such as building materials, furniture, and cleaning products.
• Inadequate ventilation and airtight spaces can lead to the accumulation of formaldehyde indoors, resulting in higher concentrations compared to the outdoor environment.

 

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

Key Points Statement I: The first Digital university of India has been established in Kerala.

• Kerala University of Digital Sciences, Innovation and Technology (DUK) is the  first Digital university of India,
• The DUK was established by the Government of Kerala in 2020.
• The DUK is a state university located in Technocity, Mangalapuram, Pallippuram, Thiruvananthapuram, Kerala, India.
• The DUK offers postgraduate and research programs in a variety of digital technologies.
• The DUK is committed to providing high-quality education and research in digital technologies.

Statement I is correct

Statement II: India's first Defence university is situated in the state of Haryana.

• National Defence University (NDU), is the first Defence University of India.
• It is situated in the state of Haryana
• The NDU was established by the Government of India in 2022.
• The NDU is a central university located in Manesar, Gurgaon, Haryana, India.
• The NDU offers undergraduate, postgraduate, and research programs in a variety of defence-related subjects.
• The NDU is committed to providing high-quality education and research in defence-related subjects.

Statement II is also  correct

Therefore, both statements are correct.

Key Points 

The introduction of English system of higher education in India had a number of outcomes, including:

• Acquaintance with western literature and scientific knowledge. 
• ​This was one of the most important outcomes of the introduction of English education in India. Students were now able to learn about Western ideas and concepts, which had a profound impact on Indian thought and culture.
• Emphasis on material prosperity. 
• ​The English system of education placed a strong emphasis on material prosperity. This was reflected in the curriculum, which focused on subjects such as economics, commerce, and engineering.
• Rise of social consciousness in India. 
• The introduction of English education also led to the rise of social consciousness in India. Students were exposed to Western ideas about equality and justice, which led to a growing awareness of the social problems in India.

However, the introduction of English education also had some negative consequences, such as:

• Relegation of women's education to the lowest level. 
• Women were largely excluded from the English system of education, which led to a decline in women's education in India.
• Status quo in Indian education system. 
• The English system of education did not fundamentally change the Indian education system. It simply added a new layer on top of the existing system.

 

Therefore, the correct answer is 3, C, D, and E.

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

Key Points

• (A) states that "Zambia was a rich and developed nation in 1964". This statement is partly misleading:
• While the passage mentions Zambia had promising prospects and plentiful copper resources (indicating resource richness), it does not specifically label Zambia as a "developed" nation in 1964.
• Therefore, based on the passage, we can conclude that (A) is not entirely accurate.
• (R) says, "It had rich copper resources" - this statement aligns with the information given in the passage which explicitly mentions that "Zambia was rich in copper".
• Hence, we can conclude that (A) is not correct but (R) is correct.

Therefore, the correct answer is Option 4.

The correct answer is 'A and B only'.

Key Points

• Statement A says "Conditions in Zambia have improved since the 1990s." The passage affirms this by stating "While conditions have improved somewhat since then..."
• Statement B asserts "Zambia has one of the lowest living standards in the world." The passage also confirms this by saying "Zambia still has one of the lowest standards of living in the world."
• However, Statement C is incorrect. It states "The Zambian leader Kenneth Kaunda was quite popular at home in the 1990s". The passage does not support this claim; instead, it tells us that Kaunda was voted out of office amid political unrest and food riots in the 1990s.

Therefore, the correct answer is Option 1.

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

Key Points

• Assertion (A) states "South Korea developed much faster than Zambia after 1964". The passage supports this by outlining the contrasting economic trajectories of the two countries.
• Reason (R) states "In 1964, conditions in South Korea were far more promising for growth and development than in Zambia." This is incorrect as per the passage which states that in 1964, Zambia's prospects seemed more promising than those of South Korea.
• Thus, while both statements are correct, (R) is not the correct explanation of (A).

Therefore, the correct answer is Option 3.

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

Key Points

• Statement I asserts that "In 1964, Zambia was far more developed than South Korea". This is contradicted by the passage, which states that both nations were at roughly equivalent levels of development in 1964.
• Statement II is correct. It states "Zambia was ruled by an elected president in 1964." The passage confirms this by noting that Kenneth Kaunda was elected president when Zambia achieved its independence in 1964.

Therefore, the correct answer is Option 4.

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

Key Points

• Assertion (A) states "The Zambian leader was quite popular in his country in 1964". This is supported by the passage, which describes Kenneth Kaunda as "popular at home".
• Reason (R) asserts "Zambia achieved significant growth in its economy under his leadership." This is not supported by the passage. It actually states that "Zambian income per person fell" during Kaunda's leadership.
• Therefore, while both statements are correct, (R) is not the correct explanation of (A).

Therefore, the correct answer is Option 3.
