UGC NET Paper 1: Held on 11th Dec 2023 Shift 2 (Previous Year Paper)

Given:

Total Expenditure of Company A = Rs. 80 lakh.

Total Expenditure of Company B = Rs. 90 lakh.

Calculation:

Expenditure on Infrastructure of Company A = 18% of 80 lakh 

⇒ 18/100 × 80,00,000 

⇒ 18 × 80,000

⇒ Rs. 14,40,000

Expenditure on Transportation of Company B = 14% of 90 lakh

⇒ 14/100 × 90,00,000

⇒ 14 × 90,000

⇒ Rs. 12,60,000

Required ratio = 14,40,000 / 12,60,000

⇒ 144 : 126

⇒ 8 : 7

∴ The correct answer is 8 : 7.

Given: 

Total Expenditure of Company A = Rs. 80 lakh

Total Expenditure of Company B = Rs. 90 lakh

Total Expenditure of Company C = Rs. 75 lakh

Calculation:

Expenditure on Infrastructure of Company A = 18% of 80 lakh 

⇒ 18/100 × 80,00,000

⇒ 18 × 80,000

⇒ Rs. 14,40,000

Expenditure on Infrastructure of Company B = 15% of 90 lakh

⇒ 15/100 × 90,00,000

⇒ 15 × 90,000

⇒ Rs. 13,50,000

Expenditure on Infrastructure of Company C = 24% of 75 lakh

⇒ 24/100 × 75,00,000

⇒ 24 × 75,000

⇒ Rs. 18,00,000

Average = (14,40,000 + 13,50,000 + 18,00,000) / 3

⇒ 45,90,000 / 3 

⇒ Rs. 15,30,000

∴ The correct answer is Rs. 15.3 lakh.

Given:

Total Expenditure of Company A = Rs. 80 lakh

Total Expenditure of Company C = Rs. 75 lakh

Calculation:

Expenditure on Salary of Company C = 21% of 75 lakh

⇒ 21/100 × 75,00,000

⇒ 21 × 75,000

⇒ Rs. 15,75,000

Expenditure on Transportation of Company A = 15% of 80 lakh

⇒ 15/100 × 80,00,000

⇒ 15 × 80,000

⇒ Rs. 12,00,000

Required percentage = 15,75,000 / 12,00,000 × 100

⇒ 1575 / 12

⇒ 131.25 ≈ 131%

∴ The correct answer is 131%.

Given:

Total Expenditure of Company A = Rs. 80 lakh

Total Expenditure of Company B = Rs. 90 lakh

Calculation: 

Expenditure on salary of Company A = 24% of 80 lakh

⇒ 24/100 × 80,00,000 

⇒ 24 × 80,000

⇒ Rs. 19,20,000 

Expenditure on Raw material of Company B = 9% of 90 lakh

⇒ 9/100 × 90,00,000

⇒ 9 × 90,000

⇒ Rs. 8,10,000

Required difference = 19,20,000 - 8,10,000

⇒ Rs. 11,10,000

∴ The correct answer is Rs. 11.1 lakh.

Given:

Total Expenditure of Company A = Rs. 80 lakh.

Total Expenditure of Company C = Rs. 75 lakh.

Calculation:

Expenditure on infrastructure of Company C = 24% of 75 lakh

⇒ 24/100 × 75,00,000

⇒ 24 × 75,000

⇒ Rs. 18,00,000

Expenditure on Bonus of Company A = 10% of 80 lakh

⇒ 10/100 × 80,00,000

⇒ 10 × 80,000

⇒ Rs. 8,00,000

Difference = 18,00,000 - 8,00,000

⇒ Rs. 10,00,000

Required difference = 10,00,000 / 8,00,000 × 100

⇒ 10/8 × 100

⇒ 125%

∴ The correct answer is 125%.

Key Points

• Assertion (I) describes the role of political socialization within the framework of communication.
• Political socialization is the process by which individuals learn and frequently internalize a political lens framing their perceptions of how power is arranged and how the world around them is (and should be) organized; those perceptions, in turn, shape and define individuals’ definitions of who they are and how they should behave in the political and economic institutions in which they live.
• This learning comes from both intentional education and a more organic assimilation from the environment around them, which includes family, friends, media, and education. Hence, relating it to social learning in the context of attaining power makes sense because it encompasses the methods through which individuals learn about the distribution of power, the operation of political systems, and their role within these systems.
• Assertion (II) suggests that marginalization is the basis of political socialization, which is a narrower and less accurate perspective. Political socialization is a broader process that can be influenced by numerous factors, including cultural traditions, family, educational systems, social groups, and mass media.
• While marginalization and the experiences of marginalized communities can indeed influence political socialization by shaping perspectives on power, inequality, and justice, it is not accurate to say that marginalization is "the basis" of political socialization for everyone. Individuals from a wide range of backgrounds, not just those who are marginalized, undergo political socialization.

 

Therefore, while Assertion (I) captures an essential aspect of the political socialization process, Assertion (II) offers a constrained view that does not adequately represent the broad and varied mechanisms of political socialization. Hence, the correct answer is that Statement I is true, but Statement II is false.

Key Points 

• When individuals post journal-like entries on the Internet, they engage in a form of online expression known as blogging.
• The term "weblog" was coined to describe this activity, which essentially combines the words "web" and "log" to refer to logging or journaling on the web.
• A weblog, or "blog" as it is more commonly abbreviated, is a type of website or part of a website where the content is presented in reverse chronological order (newest content appear first).
• Blogs often provide commentary or news on a particular subject, such as food, politics, or education; others function more as personal online diaries. Over time, blogs have evolved to include personal websites and corporate tools for communication and information sharing.

Therefore, the correct answer is 3) Weblogs.

The correct answer is-Adequate resources and technology

<br> <br> <br>

Key Points 

• Effective teaching requires a combination of elements tailored to meet the diverse needs of students. Among the options provided, "Adequate resources and technology" stands out as a fundamental requirement for effective teaching for several reasons:
• Enhances Learning: Adequate resources and technology can significantly enhance the learning experience by providing varied and interactive content. This can help cater to different learning styles and preferences, making education more inclusive and effective.
• Access to Information: With the right technology, both teachers and students have access to a vast amount of information beyond traditional textbooks. This enables a more comprehensive and updated learning process that can adapt to new developments in various fields.
• Engagement: Technology can increase student engagement through interactive and multimedia content. This can make learning more enjoyable and interesting, leading to better understanding and retention of material.
• Personalization: Technology allows for personalized learning experiences. Tools and apps can adapt to the learner's pace and style, offering tailored support and challenges. This is particularly vital in addressing the unique needs and abilities of each student, something that traditional teaching methods may not fully accommodate.
• Preparation for Future Demands: In a world increasingly driven by technology, incorporating adequate resources and technology in education is crucial for preparing students for future demands. It equips them with the necessary skills and competencies required in the modern workforce.

Key Points

• Sub-text refers to the underlying or implicit meaning embedded within a message that is not directly stated or overtly expressed. Unlike the explicit content that is readily apparent and can be understood by simply reading or listening to the words, sub-text requires interpretation and a deeper analysis to grasp. It involves reading between the lines to understand the fuller message that the speaker or author intends to convey, which might reflect underlying themes, motives, or emotions.
• Sub-text is a critical concept in various forms of communication, including literature, film, theatre, and everyday conversation. It enriches the content, adding depth and complexity by allowing for multiple interpretations and insights into the characters, situations, or the speaker's true intentions.
• "Hidden Message" implies that there is a message intentionally concealed within another message. While this can sometimes overlap with sub-text, hidden messages are often more about secret codes or messages not meant to be understood by everyone, rather than the nuanced, implied meanings that constitute sub-text.
• "Intrinsic Message" suggests a message that is inherently part of something else but doesn't specifically denote the concept of an underlying, unspoken message within the expressed content.
• "Non-expressive Message" is not a commonly used term in this context and doesn't accurately describe the idea of an implicit message. It could imply a message that lacks expression, which is not what the sub-text is about.
• Sub-text is the correct term because it directly addresses the layer of meaning that lies beneath the explicit or surface level of communication, adding depth and richness to the primary message. It is not simply hidden or inherent; it is crafted through the choice of words, tone, context, and the dynamics between characters or the speaker and audience, requiring critical thinking and interpretive skills to uncover.

Key Points 

• Global Warming Potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere up to a specific time compared to carbon dioxide. The GWP of a gas depends on its ability to absorb energy and how long it stays in the atmosphere.
• Among the gases listed, the general understanding of their GWP in ascending order, where Carbon Dioxide (CO2) is set as the baseline with a GWP of 1 over a 100-year period, is as follows:
• Carbon Dioxide (CO2) has the lowest GWP and is used as the benchmark.
• Methane (CH4) has a higher GWP than CO2. Over a 100-year period, it's GWP is about 28-36 times higher than CO2.
• Nitrous Oxide (N2O) has an even higher GWP, about 265-298 times that of CO2 over a 100-year period.
• Chlorofluorocarbons (CFCs), depending on the specific type, can have a significantly higher GWP, with some types having a GWP in the thousands or even higher compared to CO2.
• Based on this general assessment:
• The correct ascending order from lowest to highest GWP among the options provided would be:
• (B) Carbon Dioxide (CO2) (C) Methane (CH4) (A) Nitrous Oxide (N2O) (D) Chlorofluoro Carbon (CFC)

 

So, the correct option is: (B), (C), (A), (D)

The correct answer is - If I is given as false; A is false

Key Points

• Square of Opposition: The square of opposition is a diagram representing the relations between the four basic forms of propositions (A, E, I, and O), which are used in classical logic to illustrate the logical relationships.
• Propositions:
• A (Universal Affirmative): All S are P
• E (Universal Negative): No S are P
• I (Particular Affirmative): Some S are P
• O (Particular Negative): Some S are not P
• Contradictory Relationship: The contradictory pairs in the square are (A and O) and (E and I). If one is true, the other must be false, and vice versa.
• Subalternation: This denotes the relationship where the truth of a universal proposition (A or E) implies the truth of its corresponding particular proposition (I or O). Conversely, the falsity of a particular proposition (I or O) implies the falsity of its corresponding universal proposition (A or E).
• Explanation: If I (Some S are P) is false, then it means there are no S that are P. This directly contradicts the universal affirmative proposition A (All S are P), thereby making A false.

Additional Information

• Other Relationships: In addition to contradictories and subalternation, there are contraries (A and E) which cannot both be true simultaneously, and subcontraries (I and O) which cannot both be false simultaneously.
• Undetermined Cases: If A is false, O may be true or false (undetermined), and if E is false, I may be true or false (undetermined), as they are not contradictories in these scenarios.

Key Points

• Sick Building Syndrome (SBS) is primarily caused by factors related to the indoor environment of a building, including air quality. Among the options given:

Inadequate ventilation

• Inadequate ventilation can lead to a build-up of pollutants, inadequate supply of fresh outdoor air, or failure to properly vent combustion products, which can contribute to symptoms associated with Sick Building Syndrome.

Statement I is incorrect but Statement II is correct

Key Points

• Adolescence is a developmental stage characterized by significant psychological, physical, and social changes.
• While it's a period where individuals start to form their identities, it's more accurate to say that adolescents are in the process of exploring and forming their sense of self and identity rather than having a clear and definite sense of it.
• This exploration can often involve confusion, uncertainty, and experimentation with different roles and identities.
• However, Statement II accurately reflects the cognitive development that occurs during adolescence.
• As adolescents mature, their cognitive abilities expand, and they become capable of more abstract thinking.
• This includes the development of the ability to understand complex relationships and solve problems that have higher levels of complexity and difficulty. This cognitive growth is part of what enables adolescents to navigate more sophisticated social scenarios and to begin to engage in adult forms of reasoning and problem-solving.

Key Points 

• Experimenter bias effect, also known as experimenter effect, occurs when the researchers' expectations, preferences, or other characteristics inadvertently influence the participants of a study, thus affecting the study's outcome.
• This bias can lead to the subtle communication of expectations to participants in ways that might not be immediately obvious, such as through body language, tone of voice, or the manner in which questions are asked or experiments are conducted.
• As a result, the behavior or responses of the participants may be influenced not solely by the manipulation of the independent variables intended by the study but also by the researchers' non-verbal cues or biases.
• This can obscure or distort the true effect of the independent variable because the observed outcomes might reflect the experimenter’s expectations rather than the natural response to the experimental manipulation. For example, if a researcher expects a certain result from a specific group of participants, they might unconsciously interact with them in a way that encourages those results, even if the interaction seems neutral on the surface.
• Experimenter bias is a significant concern in psychological and other types of research, as it threatens the internal validity of the experiment.
• To mitigate this bias, researchers can implement double-blind procedures, where neither the participants nor the experimenters know the critical aspects of the experiment, such as who belongs to the control group and who belongs to the experimental group. This approach helps to ensure that expectations do not influence the results of the study.

The correct answer is - Statement I is false, but Statement II is true

Key Points

• Statement I is false
• The National Policy on Education 2020 states that the National Accreditation Council (NAC) under the Higher Education Commission of India (HECI) will be responsible for the accreditation of higher education institutions, not the General Education Council (GEC).
• Statement II is true
• As per the National Policy on Education 2020, one of the key objectives is for all higher education institutions to become independent self-governing institutions through a system of graded accreditation and autonomy over a period of 15 years.

Additional Information

• National Accreditation Council (NAC)
• NAC will function as the accrediting body within the HECI structure, ensuring that institutions meet certain standards of quality and performance.
• Graded Accreditation and Autonomy
• This system aims to progressively grant more autonomy to institutions as they meet specific accreditation criteria, promoting excellence and self-governance.

Both Statement I and Statement II are correct

Key Points

• Statement I is correct because, with the advent of social media and other interactive platforms, media audiences have become more active in communicating with each other. They share opinions, reviews, and content related to what they consume, thus creating a more dynamic and engaged community around media content.
• Statement II is also correct as the digital age has enabled a closer and more direct form of communication between media audiences and the creators of mass communication content. Through social media, comment sections, forums, and other platforms, audiences can provide feedback, criticism, and appreciation directly to content creators. This has allowed for a more interactive relationship where creators can also adapt and respond to their audience’s preferences and concerns.

Key Points 

• In the context of Indian logic (Nyaya Philosophy), Anumana (or inference) is a means to acquire knowledge. Anumana involves a logical structure that consists of three primary components: Pratijna (the proposition), Hetu (the reason), and Udaharana (the example). These elements revolve around three terms:
• Major term (Sadhya): The property that is being inferred or proven within the subject.
• Middle term (Hetu): The reason or the sign through which the inference is made. It establishes a relation between the major term and the minor term.
• Minor term (Pakṣa): The subject in which the presence or absence of the major term is to be established through the middle term.
• The presence of the middle term (Hetu) in the minor term (Paksha) is crucial for making a valid inference. This relation or presence is known as Pakṣadharmatā.
• Pakṣadharmatā translates to "the property of the Pakṣa," indicating that the property or characteristic (reason or Hetu) used to make an inference truly exists within the subject of inference.
• This concept ensures that there is a direct and valid connection between what you're inferring (Sadhya) and the basis on which you're making that inference (Hetu), as applied to the subject (Pakṣa).
• This relationship is essential for the inference to be considered valid, as it demonstrates the applicability of the reason or sign (Hetu) within the specific case or subject in question (Pakṣa), thus proving or disproving the proposition (Pratijna).

Statement I is correct but Statement II is incorrect

Key Points

• Statement I: Swayamprabha is an Indian government initiative that aims to provide high-quality educational content through 40 DTH (Direct to Home) television channels. This initiative broadcasts content for various levels of learning including school education, undergraduate, postgraduate, engineering, law, and other professional courses. Hence, Statement I is correct.
• Statement II: MOOCs (Massive Open Online Courses) are not only available in English, but they are also offered in a variety of languages worldwide. Many platforms that offer MOOCs collaborate with institutions from non-English-speaking countries, providing courses in languages other than English to cater to a global audience. Therefore, Statement II is incorrect.

Key Points 

• The acronym VPN stands for Virtual Private Network, not Virtual Personal Network as mentioned in option 4.
• Here's a breakdown of what it means and how it differs from the incorrect option given:
• Virtual: Refers to the non-physical, software-based nature of the network. It does not involve direct physical connections but uses software configurations to create a network within another network (the internet).
• Private: Indicates that the network is designed for private use, offering a higher degree of security and privacy. Through encryption and other security measures, a VPN ensures that the data transmitted over it remains confidential and accessible only to authorized users.
• Network: Refers to a collection of interconnected devices that can communicate with each other.
• The purpose of a VPN is to establish a secure and encrypted connection over the internet, allowing users to transmit data safely even over less secure or public networks. This is particularly useful for protecting sensitive information and maintaining privacy online.

Key Points 

• The selectivity process in mass communication typically involves the stages or processes whereby individuals consciously or unconsciously select which messages they pay attention to, how they interpret them, and what they remember. The recognized processes included in selectivity are:
• (B) Selective attention - where individuals choose to focus on certain messages while ignoring others.
• (C) Selective perception - where individuals interpret messages in a way that is consistent with their pre-existing beliefs and attitudes.
• (D) Selective retention - where individuals are more likely to remember messages that are most meaningful to them or that they agree with.

 

Given the options, the correct answer is: (B), (C), and (D) Only

The incorrect statement in the light of Inductive Argument is: (D) Only

Key Points

• Inductive arguments are characterized by the claim that their premises, if true, support the conclusion with some degree of probability but do not guarantee it.
• In inductive reasoning, even if all the premises are true, the conclusion might still be false, although such a scenario might be unlikely.
• The essence of inductive reasoning is that it deals with likelihoods, not certainties. Therefore, statement D, which suggests all the premises can't be true and the conclusion false, does not accurately describe the nature of inductive arguments.

Key Points 

• In hypothesis testing, a p-value is used to determine the significance of the results. If the p-value is less than the significance level (alpha) chosen for the test, typically 0.05 for the 5% level, the null hypothesis is rejected, indicating that the observed effect (in this case, the correlation) is statistically significant.
• Given the p-values for the correlation coefficients r1, r2, r3, and r4 are 0.97, 0.95, 0.10, and 0.03, respectively, we compare them to the 5% significance level (0.05):
• r1's p-value = 0.97, which is greater than 0.05, so it's not significant at the 5% level.
• r2's p-value = 0.95, which is also greater than 0.05, so it's not significant at the 5% level.
• r3's p-value = 0.10, which is greater than 0.05, so it's not significant at the 5% level.
• r4's p-value = 0.03, which is less than 0.05, indicating that r4's correlation is significant at the 5% level.

 

Therefore, the correlation coefficient significant at the 5% level is: r4

Key Points 

• The concept of 'Terms' in philosophy, particularly within the study of logic and semantics, involves discussions on intention and extension. Here's a brief explanation to clarify these concepts:
• Intension refers to the set of attributes or inherent characteristics shared by all objects that a term applies to. It's the internal content or the concept behind the term.
• Extension refers to the set of all objects or instances to which the term applies. It's the external manifestation or the collection of things in the real world that the term categorizes.

Based on these definitions:

• (A) Correct. This statement accurately describes the concept of intention.
• (B) Correct. This acknowledges that terms have both an intensional (conceptual) and an extensional (real-world application) component.
• (C) The extension of a term does not determine its intention. Rather, it's the intention that typically determines the extension since the set of characteristics that define a term will dictate which objects in the real world the term applies to. Thus, this statement is incorrect.
• (D) Correct. It is possible for different terms (with different intensions) to refer to the same group of objects or instances, thereby having the same extension. For example, "morning star" and "evening star" have different intentions but refer to the same object (the planet Venus) in the external world, hence having the same extension.

 

The incorrect statement in the context of 'Terms' is: (C) Only

The moving force behind the enactment of the Indian Universities Act in the beginning of the 20th Century was Lord Curzon

Key Points

• Lord Curzon, who served as Viceroy of India from 1899 to 1905, played a significant role in the reform of the Indian educational system, including the enactment of the Indian Universities Act of 1904.
• This act was aimed at reorganizing the Indian university education system to improve standards and bring about greater governmental control and regulation.

Key Points 

The correct matching for the cyber attack types and their descriptions is as follows:

• (A) Spyware - III) Keylogger used to record key presses and sending them to third-party
• (B) Phishing - I) Sending an email to lure users to a fake website to obtain their details
• (C) Ransomware - IV) Holding hostage a user's data, often for a release fee
• (D) Pharming - II) Downloading of malicious code to redirect users to fake websites to obtain their personal details

 

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

Statement I is true, but Statement II is false

 Key Points

• Assertion (I) is true to an extent because 3D printers are widely used in Computer-Aided Design (CAD) to prototype and create models based on digital designs. However, their application is not limited to CAD; they are also used in various fields like manufacturing, medicine, and more.
• Assertion (II) is false because OLEDs (Organic Light-Emitting Diodes) generate their light, and do not require any kind of back-lighting. This is contrasted with traditional LCD screens, which do require back-lighting to illuminate the screen. OLED technology allows each pixel to emit its light, allowing for deeper blacks and higher contrast ratios.

Given:

Amount in 4 years = Rs. 2016

Amount in 9 years = Rs. 2286

Calculation:

According to the question,

Interest in between given years = 2286 - 2016

⇒ Interest of 5 years = Rs. 270

⇒ Interest of 1 year = Rs. 54 

Hence, interest of 4 years = 54 × 4 = Rs. 216

Principal = Amount - Interest 

⇒ 2016 - 216 = 1800

∴ The correct answer is Rs. 1800.

The correct answer is Less than 1000 m3/person/year.

Key Points

• A region is classified as water-scarce when its annual water supplies drop below 1,000 cubic meters per person per year.
• This threshold indicates not just scarcity in terms of physical availability but also the challenges in accessing water that is safe for human use.

Given Series:

31, 37, 41, 43, 47, 53, ?, 61

The logic followed here is,

31, 37, 41 and 43 are all prime numbers.

Hence next prime number after 53 = 59 

∴ 59 is the correct answer.

<br>

'juice' is coded as 'see', 'is' is coded as 'lee' and 'sweet' is coded as 'kee'

Hence, 'kee' is the correct answer.

Key Points 

• The Preamble to the Indian Constitution mentions several values that embody the spirit and objectives of the Constitution, aiming to establish a socio-political framework based on democratic principles and social justice. These values are intended to guide the governance of the country and reflect the aspirations and ideals upon which the Indian Republic was founded.
• The Preamble specifically mentions the following values:
• Justice - social, economic, and political.
• Liberty - of thought, expression, belief, faith, and worship.
• Equality - of status and opportunity.
• Fraternity - assuring the dignity of the individual and the unity and integrity of the nation.
• These values form the cornerstone of the Indian democracy and are intended to promote a socio-political environment where all citizens can live in harmony, enjoying their rights and fulfilling their responsibilities towards the nation and each other.
• Courage is not explicitly stated in the Preamble of the Indian Constitution.
• While courage may be an underlying virtue that supports the realization of these values, along with the successful governance and defense of the nation, it is not directly mentioned among the key values outlined in the Preamble.
• The Preamble focuses more on the foundational principles that guide the governance of the country and its approach to ensuring justice, liberty, equality, and fraternity among its citizens

The correct answer is Single-Blind Study

Key Points

• A single-blind study is a type of research design in which one party, either the participants (subjects) or the researchers (investigators), does not know which intervention or treatment the participants are receiving.
• This is done to prevent bias in the research results. The specific question you asked mentions that neither the investigator nor the participant knows what treatment the participant is receiving, which might suggest a double-blind study. However, since the options and context might have been misunderstood in the translation or explanation, let's clarify both relevant terms based on the typical definitions:
• Single Blind Study: In this study design, the participants do not know whether they are receiving the treatment or are in the control group (receiving a placebo or no treatment), but the researchers do know. This design helps prevent bias from the participants' expectations affecting the study outcomes.

Key Points

• The University Education Commission, established by the Government of India in November 1948, was tasked with a comprehensive evaluation of the state of university education in the country. Under the leadership of Dr. Sarvepalli Radhakrishnan, who later became the second President of India, the commission aimed to assess and make recommendations for the reformation and development of higher education in India.
• Dr. Radhakrishnan was a distinguished philosopher, statesman, and educator, his chairmanship of this commission underscores the importance the government placed on reforming higher education at the time.
• The commission's mandate was broad and covered various aspects of university education, including the aims and objectives of university education, the quality of teaching and research, faculty qualifications, student enrollment and welfare, examination systems, and the structure and governance of universities.

The correct answer is: 2) Introduction

Key Points

• The introduction section of a research article typically outlines the theoretical background of the study and explains the rationale behind it. It discusses the existing knowledge on the topic, identifies gaps in current understanding, and states the research question or hypothesis.
• This section helps readers understand the theoretical reasons that motivated the researchers to conduct the project.

Here's why the other options are not as suitable:

• Abstract: While the abstract may briefly mention the purpose of the study, it usually focuses on the main findings and conclusions rather than the theoretical underpinnings.
• Discussion: The discussion section primarily interprets the research findings, their implications, and limitations. While it might mention the initial theoretical framework, it doesn't delve into the specific reasons for initiating the research.
• Methodology: This section describes the methods and materials used to conduct the research. It doesn't delve into the theoretical context or motivations behind the study.

 

Therefore, the introduction section is the best place to find information about the theoretical reasons that led to a research project.

Key Points 

Hence the correct matching is (A)-(IV), (B)-(III), (C)-(II), (D)-(I)

Important Points 

A) Samavartana - (IV) Convocation ceremony

• Samavartana signifies the ceremony that marks the completion of one's formal education.
• In ancient India, this was a significant milestone for students of Vedic studies, symbolizing the end of their time living and studying with their teacher (guru), and their readiness to enter the next phase of their life, which often included household duties, professional endeavors, and societal responsibilities.
• It was a ritualistic acknowledgment of their educational and spiritual growth, and it permitted them to participate fully in the socio-religious aspects of life.

B) Vasu - (III) Who completed a course of 24 years or any two Vedas

• In the Vedic educational system, a Vasu refers to someone who has completed an extensive study lasting 24 years or who has mastered any two of the four Vedas.
• It's indicative of a significant level of scholarly achievement, reflecting both the depth and breadth of understanding in Vedic texts.
• This classification showcases the structured approach to Vedic education, where scholars progressively study and internalize the teachings of these ancient texts.

C) Rudra - (II) Who completed a course of 36 years or any three Vedas

• A Rudra, in the context of Vedic education, is an even more advanced scholar who has spent 36 years in the study or has mastered three of the four Vedas.
• This title denotes a deeper mastery and comprehension of the Vedic literature, signifying an individual who has dedicated a considerable portion of their life to understanding and preserving these sacred texts.
• It reflects a high degree of dedication and scholarly accomplishment.

D) Aditya - (I) Who completed a course of 48 years or the study of four Vedas

• Achieving the status of Aditya represents the pinnacle of Vedic scholarship, denoting someone who has completed a staggering 48 years of study or has mastered all four Vedas.
• This demonstrates an exceptional level of dedication, knowledge, and spiritual understanding.
• An Aditya is considered a master of Vedic knowledge, embodying the comprehensive wisdom contained within these foundational texts of Hinduism.

Key Points 

• To evaluate these statements, we need to convert between decimal (base-10) and binary (base-2) numbers.

Statement I says (499)_10 is equivalent to (111110011)_2. Let's verify this by converting 499 from decimal to binary:

• 499 in binary:
• 499 / 2 = 249 remainder 1
• 249 / 2 = 124 remainder 1
• 124 / 2 = 62 remainder 0
• 62 / 2 = 31 remainder 0
• 31 / 2 = 15 remainder 1
• 15 / 2 = 7 remainder 1
• 7 / 2 = 3 remainder 1
• 3 / 2 = 1 remainder 1
• 1 / 2 = 0 remainder 1

Reading the remainders from bottom to top, 499 in binary is indeed 111110011. So, Statement I is correct.

Statement II says (1011101)_2 is equivalent to (93)_10. Let's verify this by converting 1011101 from binary to decimal:

• 1011101 in binary is:
• 1*(2^6) + 0*(2^5) + 1*(2^4) + 1*(2^3) + 1*(2^2) + 0*(2^1) + 1*(2^0)
• 64 + 0 + 16 + 8 + 4 + 0 + 1
• 93
• So, 1011101 in binary is indeed 93 in decimal. Therefore, Statement II is also correct.

 

Given the evaluations, the correct answer is:Both Statement I and  Statement II are correct.

Given :

Speed while going = 30 Km/hr

Speed while returning = 90 Km/hr

Total time taken = 8 Hour

Calculation:

Let the distance between the two places be D.

According to the question,

⇒ D/30 + D/90 = 8

⇒ 4D/90 = 8

⇒ D = 180

Total distance covered by him = 2D = 360 km.

∴ The correct answer is 360 km.

Shortcut Trick

Milk parts are constant in both ratios (7 : 4 and 7 : 6).

Difference in Water parts = 6 − 4 = 2 units.

2 units corresponds to 20 litres added ⇒ 1 unit = 10 litres.

New total quantity of mixture = 7 + 6 = 13 units.

Total New Quantity = 13 × 10 = 130 litres.

∴ The correct answer is 130 Litres.

Alternate Method

Given: Ratio of Milk and Water = 7 : 4. 55L mixture sold, 20L water added. New ratio = 7 : 6.

Remaining Mix M : W = 7 : 4

+20L Water

New Mixture M : W = 7 : 6

Milk parts (7) remain same. Only water changes.

⇒ Let the quantity of milk and water in the remaining mixture be 7x and 4x respectively.

⇒ According to the question, 20 litres of water is added to the mixture.

⇒ New ratio of Milk : Water = 7x : (4x + 20)

⇒ 7x ÷ (4x + 20) = 7 ÷ 6

⇒ 6x = 4x + 20

⇒ 2x = 20

⇒ x = 10

⇒ New quantity of mixture = 7x + (4x + 20) = 11x + 20

⇒ New quantity = 11 × 10 + 20 = 110 + 20 = 130 Litres.

∴ The correct answer is 130 Litres.

Additional Information

Ratio Stability Principle

When a part of a mixture is removed, the ratio of components in the remaining mixture remains exactly the same as the initial ratio.

Constant Component Method

If only one component (e.g., water) is added or removed, the quantity of the other component (e.g., milk) must be equated across the ratios to solve the problem quickly.

Alligation Rule

Quantity of cheaper ÷ Quantity of dearer = (CP of dearer − Mean price) ÷ (Mean price − CP of cheaper).

Plutonium - 239 (option 2) is a fissile element.

 Key Points

• Fissile element: An element is considered fissile if its nucleus can readily undergo fission, which is the splitting of the nucleus into lighter nuclei when bombarded with slow-moving neutrons. This process releases a large amount of energy.
• Thorium-232 (option 1): Thorium is not a fissile element. While it can be fissioned, it requires high-energy neutrons, making it impractical for most nuclear applications.
• Uranium-237 (option 3): This isotope is not naturally occurring and is not readily fissile. It requires specific conditions and can be used as a fuel in some reactors, but not in the same way as fissile elements.
• Uranium-238 (option 4): This is the most abundant isotope of uranium, but it is not fissile. However, it can be bombarded by neutrons to produce fissile Plutonium-239 through a process called breeding.

Therefore, only Plutonium-239 possesses the specific characteristic of undergoing fission readily with slow-moving neutrons, making it a fissile element.

The key element for the formation of photochemical smog is 2) Sunlight.

Key Points

• Sunlight: Photochemical smog is formed through a series of chemical reactions triggered by sunlight, specifically ultraviolet (UV) radiation. This radiation initiates the process by breaking down nitrogen oxides (NOx) into highly reactive free radicals.
• Water vapor: While water vapor can be present in photochemical smog, it is not essential for its formation. It can influence the specific reactions and product formation, but its absence wouldn't prevent smog formation entirely.
• High temperature: Warmer temperatures can favor the formation of photochemical smog, as some of the reactions involved proceed faster at higher temperatures. However, smog can form under a range of temperatures, particularly if sunlight and other crucial components are present.
• Snow: Snow acts as a surface on which pollutants can settle and accumulate. It has no direct role in the chemical reactions that lead to photochemical smog formation.

Therefore, while other factors can influence the conditions and extent of photochemical smog formation, sunlight is the essential element for triggering the necessary photochemical reactions.

Key Points 

• The fallacy committed in the given argument is the "Fallacy of undistributed middle."
• This fallacy occurs when the middle term in a syllogism isn't distributed in either the premise. In this case, "revolutionists" is the middle term. It connects both the subjects (Russians and Anarchists) to a predicate (revolutionists), but the argument mistakenly concludes that all of the subjects (Anarchists) must be included in another category (Russians) without proper distribution of the middle term.
• The argument incorrectly assumes that since all Russians and all Anarchists are revolutionists, they must belong to the same group (Russians, in this case), which is a logical error.

 

Therefore, the correct answer is: (C) Only

Key Points 

• In a positively skewed distribution (also known as right-skewed distribution), the tail on the right side of the distribution is longer or drawn out relative to the left side.
• This typically causes the mean to be greater than the median, as the longer tail pulls the mean to the right. Therefore, the relationships between mean, median, and mode in a positively skewed distribution are often summarized as follows:
• Mean > Median
• Median > Mode
• Given these relationships, the correct statements from the options would be:
• (A) Mean > Mode [This is a general characteristic but might not be directly applicable to all positively skewed distributions. The more correct relation in textbooks concerning skewness is Mean > Median > Mode.
• However, this option was not provided in your question contextually, indicating a possible typo or misunderstanding. The correct relationship considering positively skewed distributions is actually Mean > Median, and Median > Mode, directly. But based on the general understanding and the closest matching options:] (C) Mean > Median

 

Therefore, the correct answer from the provided options is: (A) and (C) Only

 

Hence the correct matching is (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

Key Points 

Based on the provided statements and their evaluation against the concepts in modern information technology:

• (A) This statement is correct. In traditional (classical) computing, data is indeed represented in binary digits (0s and 1s), commonly referred to as bits. Quantum computing, on the other hand, uses quantum bits or qubits, which can represent and process a much larger amount of information due to the principles of superposition and entanglement.
• (B) This statement is incorrect. A wearable device capable of activity tracking, such as measuring steps walked and heart rate, is an example of wearable technology or a fitness tracker, not WiMAX. WiMAX (Worldwide Interoperability for Microwave Access) is a technology for broadband wireless access.
• (C) This statement is incorrect. The description given matches more closely with that of a Wireless Sensor Network (WSN), which consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, and to cooperatively pass their data through the network. A Geographic Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data.

 

Given these clarifications, the correct answer is: (A) Only

Among the provided options, the one that does not correctly represent a recommendation to reduce the use of unfair means in the classroom is:

• Clear guidance about the use of unfair means and their imposed rewards that dissuade other students because of their rigidity.

Key Points

• This option mistakenly mentions "rewards" in association with discouraging unfair means, which appears to be a contradiction or misprint.
• The concept likely intended to refer to the consequences or penalties for using unfair means, not "rewards." Effective recommendations typically focus on creating a positive learning environment, offering support to students, and making the consequences of dishonesty clear and significant, not rewarding inappropriate behavior.

The correct answer is 'Both statement I and statement II are true'.

Key Points

• Statement I aligns with the passage which discusses the international political and economic systems contributing to the disadvantaged position of women globally.
• Statement II is also consistent with the text. Jackie True, in the passage, states that the policies of the International Monetary Fund (IMF) and the World Bank have led to an increase in the 'feminization of poverty'.

Therefore, the correct option answer is 'Option 1'.

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

Key Points

• (A) 20 percent of all refugees are men: This statement is correct based on the passage's information that 80 percent of all refugees are women. By implication, if 80 percent are women, then 20 percent would be men.
• (B) Less than 5 percent of women are at the top of higher organizations and positions of power: This statement is explicitly mentioned in the passage and is correct.
• (C) 60 percent of all illiterates are women: This statistic is directly provided in the passage, making the statement correct.
• (D) Women are credited with 10 percent of the total working time: This statement is incorrect. According to the passage, women do 60 percent of the total working hours but receive only 10 percent of the total income, not that they are credited with 10 percent of the working time.
• (E) Men receive 90 percent of the total income: Since the passage states that women receive only 10 percent of the total income, it can be inferred that the remaining 90 percent of the income goes to men, making this statement correct.

Therefore, the correct answer is 'Option 4'.

The correct answer is 'all over the world'.

Key Points

• The passage speaks about feminism and gender inequality on a global scale, not limiting it to developing or developed countries, or highly industrialized society.
• It explains that disparities exist everywhere, with women experiencing discrimination, poverty, and power disequilibrium universally.
• The text emphasizes that women hold just 1 percent of global wealth, less than 5 percent of high-ranking positions, and receive only 10 percent of the total income, while doing 60 percent of the total work hours.
• The problem is not contained to a specific economic or social context, but pertains to women's status worldwide.

Therefore, the correct option is 'Option 3'.

Additional Information

• While developing and developed countries, as well as highly industrialized societies, will surely exhibit specific patterns of gender inequality, choosing any of these would neglect women's experiences not encompassed under these categories. The passage emphasizes a universal problem.

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

Key Points

• Statement (B) aligns with the information in the passage, making it clear that women receive less compensation than men. Women receive only 10 percent of the total income.
• Statement (C) is also true according to the passage. It's stated that women do 60 percent of total working hours but obtain only a small fraction of total income.
• Statement (D) is validated by the passage, which notes a higher illiteracy rate among women. Sixty percent of illiterates worldwide are female.
• Statement (E) is in agreement with the text. Less than five percent of women are at the top of senior organizations and positions.

Therefore, the correct option is 'Option 4'.

Additional Information

• Statement (A) is false. Women do not have more property than men. The passage states that women hold only about 1 percent of the world's wealth.

The correct answer is 'international economy'.

Key Points

• The passage directly states that "Low-wage, extremely hard work in export processing sectors, sex tourism, and migrant domestic workers are examples of how women are exploited in the course of developing an international economy."
• This highlights that the exploitation of women isn't limited to a single nation's economy, either industrialized or developing, or the domestic economy. It spans across global economic systems, hence the term 'international economy'.

Therefore, the correct option is 'Option 1'.

Additional Information

• While certain forms of exploitation may be more prevalent in industrialized, developing, or domestic economies, the passage emphasizes that these are examples within a broad international context.
