UGC NET Questions (Paper – 1)

Statement D is the only wrong statement because population ageing clearly has implications for planning services, infrastructure and resource use. Statements A, B, C, E and F are correct: ageing populations need adapted services, age-friendly design, they contribute to environmental action, heatwaves pose higher risks to them and DRR must consider ageing. Therefore, the correct answer is the combination that identifies D alone as wrong.

Option A:
Option A is incorrect as it groups A with D as wrong, even though A correctly highlights increased demand for adapted services in ageing societies. Treating A as wrong contradicts demographic and planning evidence.

Option B:
Option B is incorrect because it labels C and D as wrong together. C accurately points out that older persons often contribute knowledge and voluntary efforts, so including it with D is unjustified.

Option C:
Option C is incorrect since it combines D with E as wrong. E is correct in noting that climate risks like heatwaves can disproportionately affect older urban residents, as seen in many city experiences.

Option D:
Option D is correct because it singles out D, which wrongly claims that ageing has no planning implications, and implicitly accepts A, B, C, E and F as true. It is consistent with the unit’s emphasis on demographic change and environmental planning.

Communication apprehension refers to an individual’s level of fear or anxiety associated with real or anticipated communication with others. Students who avoid speaking in class despite having ideas often suffer from this condition. The stem directly mentions intense fear of communication,so it clearly describes communication apprehension.

Option A:
Communication apprehension reduces classroom participation and can distort feedback to the teacher,making option A the correct barrier.

Option B:
Semantic overload would involve too much complex information or jargon,not emotional fear about speaking.

Option C:
Cultural shock is confusion or stress experienced when entering a new culture,which may affect communication but is not the specific classroom fear described.

Option D:
Mechanical failure refers to breakdowns in equipment,such as microphones,and cannot explain a student’s reluctance to speak.

Ethical research with human participants requires respect for their autonomy and dignity. Informed consent ensures that participants understand the purpose, procedures, risks and benefits before agreeing to take part. Their participation must be voluntary, and their privacy and well being should be safeguarded throughout. Protecting rights and welfare is therefore at the core of ethical research practice.

Option A:
Option A describes deliberate deception about all aspects, which violates informed consent and can only be justified in rare cases under strict conditions. Even then, debriefing is essential.

Option B:
Option B captures key ethical obligations, including informed consent, voluntariness and protection from harm. These principles are emphasized in most ethical guidelines and institutional review processes for research involving humans.

Option C:
Option C suggests publishing personal details without permission, which breaches confidentiality and privacy. Ethical standards require anonymizing data or obtaining explicit consent for disclosure.

Option D:
Option D refers to coercion by preventing withdrawal, which directly conflicts with the right to withdraw at any time without penalty.

Nyāya holds that anumiti (inferential cognition) arises when the mind apprehends the hetu in the pakṣa along with the remembered vyāpti. This focused grasping of the middle term as pervaded by the major term in that locus is called liṅga parāmarśa and is treated as the immediate psychological cause of inferential knowledge.

Option A:
Option A describes nigamana, the final verbal statement of the conclusion in a parārthānumāna, not the internal mental state that produces anumiti.

Option B:
Option B correctly identifies liṅga parāmarśa as the mental apprehension of the middle term in the pakṣa under the universal concomitance with the sādhya, which Nyāya treats as the direct cause of inference.

Option C:
Option C refers to dṛṣṭānta, the illustrative example used to convince others, which is part of external argumentation, not the inner cause of anumiti.

Option D:
Option D reduces liṅga parāmarśa to mere perception of the pakṣa; simple perception without relating the hetu to vyāpti is not yet inferential cognition.

Statements A, B, C and E are correct because they describe multi-actor governance, unequal burdens on disadvantaged groups, location of informal settlements and the role of participation in improving accountability. Statement D is false since user charges can be designed with lifeline tariffs or subsidies to protect poorer users. Statement F is false because decentralisation outcomes depend on power structures, capacity and accountability mechanisms. Thus, the option containing A, B, C and E while excluding D and F is correct.

Option A:
Option A is incorrect as it omits E and therefore does not mention participatory budgeting and planning, which are important innovations for more inclusive urban governance.

Option B:
Option B is incorrect because it excludes C, so it fails to emphasise the spatial concentration of disadvantaged groups in high-risk locations, which is central to urban environmental inequities.

Option C:
Option C is correct since it integrates governance structures, justice concerns, spatial patterns and participatory tools, while rejecting simplistic claims about user charges and decentralisation.

Option D:
Option D is incorrect as it includes D, which claims user charges cannot be pro-poor, even though carefully designed tariffs can protect vulnerable users.

Nyāya presents a five membered structure of inference in which dṛṣṭānta (or udāharaṇa) is the stage where an example is given to show the universal concomitance between hetu (reason) and sādhya (probandum). For instance, citing “the kitchen where there is smoke and fire” illustrates the smoke–fire relation. This concrete case helps establish the vyāpti that underlies the reasoning.

Option A:
Option A, pratijñā, is the proposition or thesis to be proved, not the example.

Option B:
Option B, hetu, is the reason or sign used in inference, such as “there is smoke on the hill.”

Option C:
Option C correctly names dṛṣṭānta as the example that demonstrates the general connection between reason and what is to be proved.

Option D:
Option D, nigamana, is the final conclusion statement that restates the thesis in light of the reason, not the illustrative example.

A, B, C and E are correct; D is false. Soundness is a property of valid deductive arguments with true premises, not something “inductive rather than deductive”. Deduction aims at certainty (given validity and true premises), induction at probability; if a deductive conclusion is false then validity or premises fail. Distinguishing them is common in UGC NET.

Option A:
Option A is incorrect because A is true; it wrongly includes A as wrong.

Option B:
Option B is incorrect because C is true; grouping it with D as wrong is incorrect.

Option C:
Option C is incorrect because B and E are true; treating them as wrong makes the option invalid.

Option D:
Option D is correct because D is the only wrong statement.

SWAYAM hosts digital courses designed by recognised national coordinators and institutions, covering various disciplines. Learners can access video lectures, readings, quizzes and sometimes proctored exams through this ICT-based platform. The initiative aims to expand access and improve equity and quality in education. This option captures its primary goal.

Option A:
This option correctly highlights that SWAYAM uses ICT to deliver structured courses at scale and often supports credit transfer. It shows that the platform is part of broader digital initiatives in Indian higher education.

Option B:
Limiting the platform to printed materials ignores its online, multimedia nature. SWAYAM is web based and not confined to one city.

Option C:
A social media platform for personal photos serves a completely different purpose from academic MOOCs. SWAYAM focuses on formal learning, not casual social sharing.

Option D:
Banning ICT is contrary to the very idea of SWAYAM, which promotes technology use for education.

Statements A, B, D and E are correct because agrobiodiversity covers crops, livestock and associated species, genetic diversity improves resilience, on-farm conservation preserves varieties and dietary diversity relies on a range of species and products. Statement C is wrong since monocultures often reduce resilience by narrowing genetic bases, and F is wrong because seed and gene banks are central ex situ tools for conserving agricultural biodiversity. Thus, the correct combination must include A, B, D and E while excluding C and F.

Option A:
Option A is incorrect because it lists only A, B and D and omits E, thereby ignoring the important link between diversity on farms and diversity on plates. Since dietary diversity is a widely recognised outcome of agrobiodiversity, leaving out E makes the answer incomplete.

Option B:
Option B is incorrect as it includes C, which wrongly asserts that monocultures always enhance resilience, and omits E. Accepting C contradicts evidence that genetically uniform systems can be highly vulnerable to shocks, so this combination mixes valid and invalid statements.

Option C:
Option C is correct since it gathers all four true statements about the roles and implications of agrobiodiversity and excludes the two that misrepresent monoculture effects and the role of gene banks. It provides a balanced view encompassing production, resilience, conservation and nutrition.

Option D:
Option D is incorrect because it includes F, which treats gene banks as irrelevant, even though they are key institutions for conserving genetic resources, and omits A, which defines agricultural biodiversity itself. As a result, this option fails both on definition and on conservation mechanisms.

Inclusive education is based on the principle that all learners, regardless of their abilities or backgrounds, should learn together in the same environment. Teachers therefore need to modify methods, materials and assessments to accommodate diversity. The goal is not merely physical presence but meaningful participation and learning for every student. Adapting strategies is central to this approach.

Option A:
This option views diversity as a problem, which contradicts the inclusive philosophy that sees diversity as a resource. Trying to eliminate differences can lead to exclusion and assimilation pressures.

Option B:
This option correctly captures the proactive role of the teacher in inclusive settings. It implies differentiated instruction, supportive assessment and sensitivity to barriers faced by particular groups. By adjusting teaching rather than expecting students to conform to a single pattern, the teacher creates a more equitable learning environment.

Option C:
This option advocates segregation, which is against the core idea of inclusive education. While some specialized support may be needed, it should be provided within or linked to mainstream settings wherever possible.

Option D:
This option suggests ignoring language and cultural backgrounds, which can make some learners feel invisible. Inclusive teaching calls for recognizing and valuing students’ cultural capital, not erasing it.

Grounded theory research seeks to develop a substantive or formal theory that is grounded in, or emerges from, the data collected rather than being imposed a priori. Researchers collect and analyse data concurrently, using constant comparison to refine categories and their relationships. Sampling is often theoretical, with new participants chosen to elaborate or challenge emerging concepts. Thus, the qualitative approach described in the stem is known as grounded theory research.

Option A:
Phenomenological research focuses on understanding the essence of lived experiences from participants’ first-person perspectives and does not primarily aim to build theory in the systematic, category-based way that grounded theory does.

Option B:
Grounded theory emphasises iterative cycles of coding, memo writing and category development that lead to a theory closely tied to participants’ accounts. This inductive process of theory generation fits the description in the question, making this option correct.

Option C:
Ethnographic research concentrates on describing and interpreting cultural practices and shared meanings in a group through prolonged fieldwork. While some conceptual insights may emerge, the explicit goal is not always formal theory generation.

Option D:
Narrative research examines people’s stories and the way they construct meaning over time, focusing on plot, characters and narrative structure rather than on building a generalisable theory from coded data.

Quantitative research relies on numerical data that must be organized and interpreted systematically. Statistical techniques allow researchers to describe patterns, relationships and variability in the data. Through procedures such as estimation, significance testing and confidence intervals, researchers can test hypotheses and draw inferences about populations from samples. Thus statistical analysis is central to quantitative data interpretation.

Option A:
Option A minimizes the use of numerical structure by emphasizing personal impressions, which undermines objectivity. While interpretation is necessary, it should be grounded in statistical evidence.

Option B:
Option B correctly states that quantitative analysis uses statistics for both description and inference. It captures the dual roles of summarizing data and testing hypotheses, reflecting standard practices in quantitative methodology.

Option C:
Option C suggests ignoring numerical patterns, which defeats the purpose of collecting quantitative data. Qualitative description has its place but cannot substitute for statistical analysis in quantitative studies.

Option D:
Option D indicates selective use of data to support preconceived opinions, which is unethical and methodologically flawed. Proper analysis should consider all relevant data, not just convenient subsets.

To find the two's complement of −18 in 8 bits, we first write +18 as binary: 00010010₂. We then invert the bits to obtain the one's complement 11101101₂ and add 1 to get 11101110₂. This 8-bit pattern uniquely represents −18 in two's complement form. Hence, 11101110₂ is the correct encoding.

Option A:
Option A correctly follows the two's complement procedure: write the positive magnitude, invert all bits, and add one. The resulting pattern 11101110₂ yields −18 when interpreted as a signed 8-bit integer. Thus, this option matches both the algorithm and the value.

Option B:
Option B, 11101101₂, is only the one's complement of +18 and does not include the final +1 step. In two's complement arithmetic, stopping at the one's complement gives the wrong numeric value. Therefore, this pattern does not represent −18.

Option C:
Option C, 11110010₂, corresponds to a different negative number when decoded as two's complement (−14). It arises from using an incorrect starting magnitude or misapplying the inversion and addition process.

Option D:
Option D, 10010010₂, resembles the sign-magnitude representation of −18, with the sign bit set and remaining bits for magnitude. However, two's complement is not sign-magnitude, so this pattern is not correct in that coding system.

Kevalānvayi anumāna is based entirely on positive instances, with no genuine negative cases available for observing absence. The classic example is the knowable–nameable relation, because all knowable objects are said to be nameable. There is no case of a knowable that is not nameable. This yields a purely affirmative pattern where inference relies on universal affirmation alone.

Option A:
Option A is usually treated as anvayavyatireki since we can cite both positive and negative smoke–fire instances. It is not purely positive.

Option B:
Option B correctly gives the knowable–nameable example in which only positive instances are available and the vyāpti is affirmed everywhere, fitting kevalānvayi.

Option C:
Option C commits a fallacy by inferring “pot” from “breakable,” because many non pots are also breakable; it is not an illustration of kevalānvayi.

Option D:
Option D reverses the common smoke–fire direction and still depends on positive and negative cases, so it does not serve as the stock kevalānvayi example.

Environmental Impact Assessment is a preventive environmental management tool used before major projects are approved. Its primary role is to identify and predict potential environmental impacts, evaluate their significance and suggest mitigation measures. By doing so, it helps decision makers consider environmental costs and benefits alongside economic and social factors. Therefore, the main purpose of EIA is impact identification and evaluation prior to decision-making, as indicated in option C.

Option A:
Option A is incorrect because EIA is not a funding mechanism; it does not provide financial assistance. It is an assessment process used to guide decisions on whether and how a project should proceed.

Option B:
Option B is incorrect since EIA may lengthen approval time due to detailed studies and consultations. Its aim is environmental safeguards, not speedy clearance.

Option C:
Option C is correct because it clearly states the core activities of EIA: identifying, predicting and evaluating environmental impacts before decisions. This allows potential negative effects to be avoided, reduced or compensated.

Option D:
Option D is incorrect because increasing land value is not an objective of EIA. Any rise or fall in land prices is incidental and not part of the assessment’s purpose.
