UGC NET Questions (Paper – 1)

Statements A, C, D and E are correct, whereas B and F are wrong and together form the correct set of wrong statements. Rubrics clarify expectations, provide descriptive guidance for improvement, and can reduce misunderstandings about marks. They also support self and peer assessment when shared appropriately. However, sharing rubrics only after evaluation still affects future learning, and teacher judgement remains important in interpreting and applying rubric descriptors, so B and F misrepresent their use.

Option A:
Option A is incorrect because it marks B only as wrong and ignores F. While B is wrong about timing having no impact, F is also wrong for suggesting that rubrics replace judgement entirely. Therefore, identifying only B yields an incomplete set of wrong statements.

Option B:
Option B is correct because it isolates B and F as the problematic claims. It recognises that rubrics contribute to clear communication but are not a magic substitute for professional decision-making or timely sharing. This combination leaves A, C, D and E as correct and matches the intended answer.

Option C:
Option C is incorrect since it wrongly includes A as a wrong statement. A accurately states that rubrics make criteria transparent, which is one of their main purposes. Labeling A as wrong conflicts with assessment best practices.

Option D:
Option D is incorrect because it adds E to the wrong set alongside B and F. E is a correct statement; rubrics are widely used for self and peer assessment. Including E among wrong statements makes this combination inconsistent with educational assessment principles.

The dependency ratio compares the size of the dependent population,typically children and older persons,to the working age population. A higher ratio indicates greater economic pressure on the working population to support dependants. The formula in the stem corresponds exactly to this concept. Therefore dependency ratio is the correct term.

Option A:
Sex ratio is the number of females per thousand males or vice versa in a population. It provides information on gender balance but does not relate directly to age structure or economic support burden. Hence it does not match the ratio described in the question.

Option B:
Child ratio considers only the proportion of children relative to the total population or working age group,ignoring elderly dependants. The stem clearly includes both children and older persons,so child ratio is incomplete and not correct here.

Option C:
Dependency ratio captures the combined economic burden of supporting both younger and older dependants on the working age group. It is widely used in development planning to assess social security and employment needs. This matches exactly what the question describes.

Option D:
Urban rural ratio compares populations living in urban and rural areas and is used to study spatial distribution. It has nothing to do with age groups or dependency relationships,so it is not the right answer.

According to classical Nyaya, there are exactly four independent sources of valid knowledge: pratyaksha, anumana, upamana and sabda. Each pramana has its own distinctive causal structure and domain of application. Accepting four pramanas allows Nyaya to explain a wide range of cognitions, from direct sense experience to knowledge of remote facts conveyed by trustworthy speakers. Therefore the correct number of pramanas in Nyaya is four.

Option A:
Option A, three, would leave out one of the standard Nyaya pramanas and thus under-represent the richness of their epistemic classification. Some other schools like Samkhya accept three pramanas, but Nyaya explicitly adds comparison as a fourth. Hence three is not accurate for Nyaya.

Option B:
Option B is correct because Nyaya counts perception, inference, comparison and verbal testimony as mutually irreducible sources of knowledge. This fourfold scheme becomes a benchmark against which other Indian schools define their own pramana lists.

Option C:
Option C, five, would match neither the classical Nyaya nor the usual Navya-Nyaya enumeration, which still keeps the same four. Although some other systems add further pramanas, Nyaya remains committed to four.

Option D:
Option D, six, corresponds to pramana lists in traditions such as Bhatta Mimamsa or Advaita Vedanta, which include arthapatti and anupalabdhi; it does not describe Nyaya doctrine.

The natural greenhouse effect keeps Earth warm enough for life by trapping some outgoing infrared radiation. Human activities such as burning fossil fuels and deforestation have increased greenhouse gas levels,leading to extra warming beyond this natural level. This extra warming is known as the enhanced greenhouse effect. Therefore enhanced is the correct word to complete the phrase in the stem.

Option A:
The natural greenhouse effect refers to the baseline warming that has always existed due to naturally occurring greenhouse gases. It is essential for maintaining habitable temperatures and is not the additional human induced component highlighted in the question.

Option B:
Moderate does not correspond to any widely recognised term in climate science. While the enhanced greenhouse effect may or may not be moderate, the established term focuses on the idea of being stronger than the natural effect,not moderate.

Option C:
Shielded greenhouse effect is not an accepted expression. Shielding would imply blocking radiation rather than trapping more of it. Thus this option does not fit the phenomenon described in the stem.

Option D:
Enhanced greenhouse effect clearly indicates that the original process has been intensified by human actions. It accounts for the observed trend of rising global temperatures and changing climate patterns,exactly what the question refers to.

Persuasive communication aims to influence attitudes,beliefs or behaviours of the audience. The counsellor in the stem is urging students to change their online practices by explaining risks and benefits. This clearly seeks behavioural modification. Therefore the function is persuasive.

Option A:
Ritualistic communication focuses on shared ceremonies and symbolic acts,not practical behaviour change.

Option B:
Persuasive messages are designed to change behaviour/attitudes using reasons and appeals (risks/benefits),so the counsellor’s urging is persuasive.

Option C:
Phatic communication maintains social contact through small talk and greetings,which is different from careful risk based arguments.

Option D:
Surveillance refers to monitoring and reporting information about the environment rather than recommending actions.

Inference is the core process through which we move from given information to a new claim that is taken to follow from it. In logic, premises are connected to a conclusion precisely by acts of inference. This process can be either deductive, aiming at necessity, or inductive, aiming at probability. Therefore the mental act described in the question is correctly termed inference.

Option A:
Option A is correct because inference specifically names the reasoning step that links premises to a conclusion. Whenever we argue that something must or is likely to be true based on other statements, we are performing an inference. This term is central to the study of logical reasoning and captures exactly what the stem describes.

Option B:
Option B, explanation, is concerned with clarifying why a statement that is already accepted is true, rather than deriving a new conclusion from premises. Explanations often assume the truth of what they explain and do not necessarily involve a structured inferential move. Hence explanation does not accurately name the general process of drawing conclusions from given statements.

Option C:
Option C, description, merely reports or depicts a situation without going beyond the information presented. A description can be detailed and accurate, yet it does not by itself generate a novel claim from other statements. Thus description does not match the idea of deriving a conclusion through reasoning.

Option D:
Option D, observation, refers to noticing or perceiving facts, usually through the senses, and is a source of information rather than a logical operation on statements. Observation may supply premises, but it is not the act of connecting those premises to a conclusion. Therefore observation is not the correct choice.

Statement C is the only wrong statement because forwarding chain mails and jokes to institutional lists is unprofessional and often against policy. A, B and D reflect standard academic email etiquette regarding clarity, tone and correctness. Using clear subjects, formal language and proofreading helps maintain respect and efficiency in communication. Thus, the option that selects only C as wrong is correct.

Option A:
Option A is incorrect because it groups C and D as wrong statements. D in fact describes a positive practice of checking grammar and spelling, which is recommended in academic communication, so including it among wrong statements is not acceptable.

Option B:
Option B is correct because it isolates C as the sole wrong statement and implicitly accepts that A, B and D describe appropriate email behaviour. It matches the requirement to identify only the statements that violate professional netiquette.

Option C:
Option C is incorrect because it labels both A and C as wrong. Statement A is a well-accepted guideline for effective email communication, and pairing it with C confuses a correct practice with a poor one.

Option D:
Option D is incorrect because it treats B and C as wrong statements. B correctly emphasises avoiding slang in professional emails, so coupling it with the clearly wrong C leads to an invalid combination.

Defensive communication occurs when a person feels threatened and tries to protect their self image rather than understanding the message. The teacher in the stem rejects criticism and stops listening. This behaviour reflects defensiveness.

Option A:
Supportive communication would involve acknowledging the student's point and exploring it constructively,which is not happening here.

Option B:
Defensive behaviour focuses on self protection and rejection of feedback,which fits the teacher’s reaction.

Option C:
Empathetic behaviour would focus on understanding the student's feelings,again absent in this case.

Option D:
Phatic communication is about small talk and social contact,not reactions to criticism.

Statements A, B and C are correct as they outline key theoretical perspectives linking population and environment. Malthus focused on potential imbalances between population and food, Boserup stressed innovation under pressure and neo-Malthusians incorporate consumption and technology into impact analysis. Statement D is incorrect because many contemporary studies explicitly consider institutions and equity in population–environment debates. Therefore, A, B and C only is the correct combination.

Option A:
Option A is incomplete because it lists only A and B and omits C. Without neo-Malthusian views that integrate technology and consumption, the theoretical picture is not up to date.

Option B:
Option B is incorrect as it includes only B and C and leaves out A. Although Boserup and neo-Malthusians are important, Malthusian thinking is foundational and must be included to fully answer the question.

Option C:
Option C is correct since it gathers all three valid statements and rejects D, which wrongly claims that institutions and equity are ignored. This option reflects the evolution of thinking from simple population counts to more complex frameworks.

Option D:
Option D is incorrect because it includes D along with A and C. Accepting D would deny the rich literature on environmental justice and institutional analysis in population–environment studies.

An operating system coordinates activities of hardware components, allocates resources to programs and offers services like file management and user interfaces. It enables application software to run without needing to control hardware directly. Because of these central responsibilities, it is often described as the backbone of the computer system. Therefore, the term that completes the statement is operating system.

Option A:
Option A, compiler, translates high level language programs into machine code but does not manage hardware or provide a general user interface.

Option B:
Option B is correct because operating systems such as Windows, Linux and macOS are specifically defined as system software that manage resources and serve as intermediaries between user and hardware.

Option C:
Option C, interpreter, executes source code line by line but again is an application tool rather than the overarching management software.

Option D:
Option D, device driver, is specialised software that allows the OS to communicate with particular hardware devices, not the full management layer itself.

Statements A, B and D correctly reflect elements of ODL quality assurance: good self-learning materials, robust learner support and recognised QA norms/guidelines. Statements C, E and F are wrong because monitoring, alignment with national frameworks and appropriate assessment are necessary for credible ODL.

Option A:
Option A is incorrect because it omits D and therefore misses the role of QA norms/guidelines for recognising ODL programmes.

Option B:
Option B is incorrect because it omits B and therefore ignores learner support services, which are central to ODL quality.

Option C:
Option C is correct because it includes A, B and D and excludes C, E and F, which deny monitoring/framework alignment/assessment.

Option D:
Option D is incorrect because it includes C (false) and omits A (true), so it mixes wrong and incomplete statements.

Statements A, B and D are correct because they show that disasters affect people differently based on social conditions and that community-based approaches can build resilience. Statement C is incorrect; it treats disasters as purely natural when in fact social and economic factors shape who is most affected. Thus, the combination including A, B and D only, and excluding C, is the correct set of statements.

Option A:
Option A is incorrect because although A and B are true, it leaves out D, which correctly emphasises the importance of community-based disaster risk reduction. Without D, the option does not fully reflect approaches to reducing vulnerability.

Option B:
Option B is incorrect as it includes B and D but omits A. While B and D are true, A is also correct in recognising that marginalised groups are often more vulnerable. Leaving out A makes the combination incomplete.

Option C:
Option C is correct because it brings together A, B and D, all of which align with the social science understanding of disasters as interacting with inequalities. It also properly excludes C, which wrongly denies the role of social and economic conditions.

Option D:
Option D is incorrect since it groups A, C and D and treats C as true. The presence of C, which mischaracterises disasters as purely natural, makes the whole combination unacceptable despite including two correct statements.

The argument’s form is: All A are B; All B are C; Therefore, All A are C. This is a standard valid syllogistic pattern; if the premises were true, the conclusion would necessarily follow. However, in reality the premises “All squares are circles” and “All circles are triangles” are false. Because at least one premise is false, the argument is not sound, even though its logical form is valid. Therefore, it is valid but unsound.

Option A:
Option A would require both validity and the truth of premises, which is not satisfied here because the premises distort geometric facts.

Option B:
Option B separates form and content, recognising that the inference pattern is correct while the factual premises render the argument unsound.

Option C:
Option C is impossible, because soundness presupposes validity; an invalid argument cannot be sound.

Option D:
Option D wrongly denies the validity of the form simply because the premises are false, confusing logical structure with factual accuracy.

Statements A, B and D accurately reflect anti-ragging measures. A is true because ragging is banned and punishable under law and institutional codes. B is true as institutions establish committees and squads to monitor hostels and campuses. D is also true since anonymous or confidential reporting channels are often created to protect complainants. Statement C is false because institutions explicitly reject ragging as a permissible part of campus culture. Thus, A, B and D only are correct.

Option A:
Option A is incorrect because it includes A and B but omits D, failing to acknowledge the importance of safe reporting mechanisms that allow victims or witnesses to raise complaints without fear.

Option B:
Option B is correct because it brings together the three measures—legal prohibition, institutional committees and complaint channels—while excluding C, which normalises ragging contrary to law and policy.

Option C:
Option C is incorrect because, while B and D are true, it omits A and thus does not mention that ragging itself is formally prohibited, which is central to the anti-ragging framework.

Option D:
Option D is incorrect because it groups A with C and D, thereby accepting C’s idea of “mild ragging” as culture, which directly conflicts with the zero-tolerance stance of regulations.

A teaching–learning situation always involves someone who teaches, someone who learns and something that is to be learned. This “something” is the content or subject matter that structures the interaction between teacher and learner. Without content, the relationship would not qualify as educational in the formal sense. Hence, content or subject matter is rightly considered the third basic component of the teaching–learning process.

Option A:
The classroom environment provides the physical and psychological setting for teaching, but it is not itself a core structural component like teacher, learner and content. Environment influences how teaching occurs but does not replace the central role of subject matter. Therefore, it is not the most appropriate completion for the statement.

Option B:
The institutional timetable organizes when classes occur but is an administrative tool rather than a conceptual component of the teaching–learning process. It deals with scheduling, not with the substance of educational interaction. Hence, it cannot be placed alongside teacher and learner as a basic component.

Option C:
Content or subject matter represents the organized body of knowledge, skills and values that teaching aims to communicate and develop. It provides focus and direction to classroom activities and assessments. This option correctly completes the triad of teacher, learner and content in most models of teaching.

Option D:
Physical infrastructure such as buildings and furniture supports teaching but does not define the essential structure of the teaching–learning process. Learning can occur even with minimal physical facilities if teacher, learner and content interact effectively. Therefore, it is not the central third component referred to in the question.
