UGC NET Questions (Paper – 1)

Statements A, B, C, D and F are correct because they describe major indices and note that indicators help inform but do not replace judgement. Statement E is false since choices about what to measure and how to weight indicators always involve normative decisions. Hence, the combination that includes all correct statements and excludes E is correct.

Option A:
Option A is correct as it captures different measurement tools and emphasises cautious policy use, while rejecting the notion that index construction is entirely free of value judgements.

Option B:
Option B is incorrect because it leaves out F and therefore fails to highlight that contextual interpretation is necessary to avoid mechanical use of indices.

Option C:
Option C is incorrect since it includes E, which wrongly claims that index design is purely objective, even though value choices are inherent in indicator selection.

Option D:
Option D is incorrect as it omits B, so it loses the definition of ecological footprint, which is one of the key indicators discussed in this unit.

Statements A, B, D and E capture key dimensions of digital and information literacy, while C and F are oversimplified or false. Operating devices is only a basic technical skill; evaluating content and citing sources are higher-order academic competencies. Collaborative online projects further extend communication and teamwork skills. The belief that all “digital natives” automatically have advanced critical skills is unfounded, so the correct set is A, B, D and E only.

Option A:
Option A is incomplete because it omits E, which recognises the role of collaborative work in building communication competencies. Without E, the set underrepresents the social aspects of digital learning.

Option B:
Option B is incomplete because it lists B, D and E without A. Statement A provides the overarching definition of information literacy, so its absence makes the combination less conceptually complete.

Option C:
Option C is correct because it brings together statements that define, extend and operationalise digital literacy for academic work. By excluding C and F, it rejects views that reduce digital skills to button-pressing or assume that age alone guarantees critical competence.

Option D:
Option D is incorrect because it includes F, which assumes no further training is needed for students raised with technology. Research shows that critical digital skills require explicit instruction and practice, so this option cannot be correct.

A gatekeeper is someone who controls which information enters the communication system and how it is shaped before being passed on. Editors decide which events become news,how they will be framed and which items will be dropped. In Westley and MacLean's model,this selective function is central,so the editor acts as a gatekeeper.

Option A:
Gatekeepers influence public knowledge and opinion by opening or closing the gates for certain messages. They are active decision makers,not passive conduits,which fully matches the description in the stem.

Option B:
Feedback givers respond to messages after they are received rather than selecting them beforehand. That role belongs to audiences or regulators,not editors in this model.

Option C:
Receivers are those who consume the final messages rather than shape them during production.

Option D:
Noise sources unintentionally distort messages and do not deliberately choose what to include or exclude.

Netiquette refers to appropriate and respectful behaviour in online environments. In virtual classrooms, joining on time shows respect for the schedule, while muting reduces noise and distractions. Using platform tools like chat or raise-hand options allows orderly participation. Together, these practices help maintain a focused and inclusive learning atmosphere.

Option A:
This option correctly identifies specific actions that support clear communication and minimise technical disruptions. It reflects awareness of both the technical features and the social norms of online learning communities.

Option B:
Loud background music and constant interruptions distract the entire class and make it harder for others to follow the lesson. Such behaviour violates norms of courtesy and concentration.

Option C:
Sharing links widely invites potential intruders or “bombers” who may disrupt the session. Good netiquette involves protecting meeting credentials and respecting privacy.

Option D:
Disrespectful comments create a hostile climate and may amount to cyberbullying. They undermine trust and collaboration, which are essential for effective ICT-mediated learning.

Vyapti denotes the universal and exceptionless relation connecting the reason (hetu) with the probandum (sadhya). It states that wherever the hetu is present, the sadhya is also present, and wherever the sadhya is absent, the hetu is absent. Establishing vyapti through positive and negative instances is what justifies moving from a perceived sign to an unperceived conclusion in anumana. Therefore the relation described in the stem is called vyapti.

Option A:
Option A, paksha, is the subject or locus in which the sadhya is to be established, such as the hill in the classic smoke–fire example. It is not the relation between hetu and sadhya.

Option B:
Option B, hetu, is the reason or middle term that indicates the presence of the sadhya, like smoke indicating fire. While hetu participates in vyapti, it is not the name of the universal relation itself.

Option C:
Option C is correct because vyapti captures the pattern “wherever this, there that” which gives inferential force to anumana. Without vyapti, the step from observed sign to unobserved property would lack rational justification.

Option D:
Option D, drstanta, is the illustrative example that shows the vyapti in a familiar case, such as a kitchen where smoke and fire always go together. It is evidence for vyapti, not the relation itself.

Statements A, B, C and E are all correct: they define the arithmetic mean, describe how adding a constant shifts the mean, explain that the updated mean lies between the old mean and the new value, and note that weighted averages incorporate differing importance through weights. Statement D is false because the average need not coincide with any actual data point; for example, the mean of 2 and 4 is 3, which is not in the list. Therefore, the combination that includes A, B, C and E and excludes D is correct.

Option A:
Option A is incomplete since it does not mention E and therefore overlooks the important idea that some aptitude problems require weighted averages rather than simple means. Without E, the concept coverage is narrower than intended.

Option B:
Option B is also incomplete: although B, C and E are true, the omission of A means the basic definition of arithmetic mean is missing. A must be included to fully represent how averages are computed.

Option C:
Option C is correct as it brings together all the true statements about how means behave and how weighted averages work, while rejecting D, which mistakenly claims that the mean must be an actual data value. It provides a complete conceptual picture for NET-level questions.

Option D:
Option D is wrong because it includes D, the false statement about averages always equalling a data point, and omits B, which correctly summarises the effect of adding a constant. This mixture makes the option logically inconsistent.

A premise is a statement that offers reasons or evidence for accepting a conclusion. It forms the supporting part of an argument on which the inference rests. Without premises, there would be no logical basis for moving to a conclusion. Therefore the statement described in the stem is correctly termed a premise.

Option A:
Option A names the conclusion, which is the claim an argument is trying to establish. The conclusion is supported by other statements rather than providing the support itself. Thus conclusion does not describe the evidential role mentioned in the question.

Option B:
Option B correctly identifies premise as the supporting statement in an argument. Premises supply the grounds from which the conclusion is inferred. Hence this option exactly matches the description of giving reasons or evidence for the conclusion.

Option C:
Option C, illustration, provides examples to clarify an idea but is not the basic name for a supporting statement. An illustration can accompany a premise but does not replace the technical role of premise in an argument. Therefore illustration is not the best term here.

Option D:
Option D, example, is a particular instance used to make a point clearer. While examples can be used inside premises, they are not the general name for statements that support a conclusion. So example is too narrow and does not answer the question precisely.

Biodiversity hotspots are areas that meet strict criteria for high levels of endemism and significant loss of original habitat. They are considered priorities for conservation investment because they contain many unique species under severe threat. The stem explicitly refers to regions with high richness,endemism and serious human pressure,which defines hotspots. Thus Option C is the correct answer.

Option A:
Corridors are habitat links connecting larger patches to aid movement of species. They are not defined by exceptionally high endemism and threat levels.

Option B:
Reserves are protected areas,which may exist within or outside hotspots. “Reserve” does not inherently mean high endemism plus high threat.

Option C:
Hotspots are conservation priority regions characterised by exceptional endemism and serious habitat loss or threat,matching the stem precisely.

Option D:
Commons are shared resources managed by communities; the term does not specifically denote high endemism and high threat as in the hotspot concept.

Statements A, B and C correctly define tautology, contradiction and contingency by looking at truth across all valuations. Statement E is also true because the negation of a formula that is always true must be false on every valuation, hence a contradiction. Statement D is impossible in classical logic, since no statement can be both always true and always false at once. Therefore, the complete set of correct statements is A, B, C and E only, which matches option C.

Option A:
Option A is incomplete because it omits E and therefore fails to mention the important relationship between tautologies and contradictions via negation. It lists correct information but not the full set of true statements for this question.

Option B:
Option B is incorrect since it leaves out B and includes only A, C and E, ignoring the explicit definition of contradiction that is central to the topic. Without B the description of the three categories is not complete.

Option C:
Option C is correct as it brings together the accurate definitions of the three types of statements and the fact that the negation of a tautology is a contradiction, while excluding D, which suggests an incoherent situation in classical logic.

Option D:
Option D is wrong because it includes D, which falsely claims that a statement can be both tautology and contradiction and calls that “contingent”, and it omits A, so it both accepts a logical impossibility and loses a key correct statement.

A, B, C and E correctly describe recognised hetvābhāsas and common exam patterns. D is wrong because asādhāraṇa hetu is not “common to many instances”; it is too restricted/unique, which makes it defective rather than ideal. Thus D alone is the incorrect statement.

Option A:
Option A is correct because it identifies D as the only wrong statement while treating A, B, C and E as correct.

Option B:
Option B is incorrect because it wrongly includes C as a wrong statement; C correctly describes bādhita hetu.

Option C:
Option C is incorrect because it wrongly includes A as wrong; A accurately characterises savyabhicāra (irregular) hetu.

Option D:
Option D is incorrect because it wrongly includes E as wrong; E correctly states a common exam pattern.

Replacement level fertility is the level of childbearing at which each generation of women is producing enough daughters to replace themselves. In human populations it is slightly above two children per woman in many contexts because some children die before reaching reproductive age. The stem clearly refers to fertility that allows a population to replace itself over time. Hence replacement level fertility is the correct term.

Option A:
High fertility simply indicates that women are having many children,typically well above the replacement level. Such fertility usually leads to rapid population growth rather than stability,so it does not fit the description in the question.

Option B:
Replacement level fertility is central to discussions of population stabilisation and long term demographic planning. When sustained over time and combined with balanced migration,it leads to a roughly stable population size. This makes it the most appropriate option for the stem.

Option C:
Total fertility normally refers to the total fertility rate,which is a measure of average births per woman but can be higher or lower than replacement level. It is a related statistic but not specifically the level at which replacement occurs.

Option D:
Optimum fertility is not a standard demographic measure and could be interpreted in various normative ways. It does not have the precise meaning described in the question stem,so it is not the best answer.

To find the smallest number to be added, we first determine the remainder when 625 is divided by 7. Since 7 × 89 = 623, the remainder is 625 − 623 = 2. A number is divisible by 7 when the remainder becomes zero, so we must add a number that brings the remainder 2 up to 7. Therefore, we add 5 (because 2 + 5 = 7), making 625 + 5 = 630, which is divisible by 7.

Option A:
Option A correctly uses the idea that the required adjustment is 7 minus the remainder. With a remainder of 2, adding 5 eliminates the remainder and yields a number (630) that lies exactly on the 7-times table.

Option B:
Option B, 2, would produce 627, and 627 ÷ 7 still leaves a remainder because 7 × 89 = 623 and 7 × 90 = 630. Thus, 627 is not divisible by 7.

Option C:
Option C, 4, gives 629, which also falls between multiples of 7 and leaves a nonzero remainder, so it does not satisfy the condition.

Option D:
Option D, 6, would lead to 631, which again does not align with a multiple of 7, because the nearest multiples are 630 and 637.

Academic capitalism refers to the adoption of market-like behaviours by universities. This includes competing for external grants, patenting research and designing revenue-generating programmes. The stem’s examples match these market-oriented practices. Therefore, “capitalism” is the correct completion of the term.

Option A:
Socialism emphasises collective ownership and egalitarian distribution and is not the concept used to describe market behaviour in universities. Thus, this option does not align with the stem.

Option B:
Capitalism focuses on markets, competition and profit-seeking, which is exactly the lens used when scholars talk about academic capitalism. It captures the commercial pressures shaping institutional strategies, making this option appropriate.

Option C:
Feudalism refers to a historical land-based hierarchical system and has no direct connection with modern university–industry relations. Hence, this option is incorrect.

Option D:
Fundamentalism is associated with rigid adherence to certain beliefs and does not describe economic strategies of universities in the global market. Therefore, this option is not suitable.

Renewable energy sources are those that are replenished naturally on a human time scale and are not depleted by regular use. Solar energy is derived from sunlight, which is essentially inexhaustible for human purposes. Using solar energy reduces dependence on fossil fuels and lowers greenhouse gas emissions. Therefore, solar energy is correctly identified as a renewable source, making option A correct.

Option A:
Option A is correct because solar energy relies on the continuous flow of solar radiation, which is naturally replenished each day. It does not get exhausted like fossil fuels and is considered a key pillar of sustainable energy transitions.

Option B:
Option B, coal, is a fossil fuel formed over millions of years and is non-renewable on human time scales. Once extracted and burnt, it cannot be quickly replaced.

Option C:
Option C, petroleum, is also a fossil fuel that is finite and non-renewable. Its extraction and use contribute significantly to air pollution and climate change.

Option D:
Option D, natural gas, while cleaner than coal and oil in terms of emissions, is still a fossil fuel and non-renewable. It also releases carbon dioxide when burned and can leak methane during extraction and transport.

Statements A, B, D and E are correct because they outline how poverty and environment interact in both directions and how policy can change the relationship. Overuse of resources can degrade environments, which then deepens poverty, but sustainable livelihoods, clean energy and secure tenure can reduce pressure and vulnerability. Statement C is false because the relationship is context-specific and complex, and F is false because poor communities do participate, though they may face barriers. Therefore, the correct combination is A, B, D and E only.

Option A:
Option A is incorrect as it lists only A and B and omits D and E. While A and B capture the basic two-way link, they ignore policy levers such as livelihood diversification and improved access to energy and land, which are central to breaking traps.

Option B:
Option B is correct because it covers both the negative feedbacks and the main positive interventions in the poverty–environment discussion. It also excludes simplistic or disempowering views represented by C and F.

Option C:
Option C is incorrect since it includes F and excludes D. F wrongly suggests poor communities never participate, ignoring examples of community forest management and other initiatives, while leaving out D underplays the role of sustainable livelihoods.

Option D:
Option D is incorrect as it again accepts F and excludes A. By omitting A, it fails to acknowledge how survival strategies can cause degradation, while still retaining a false statement about participation.
