UGC NET Questions (Paper – 1)

Statements A, B, D and E reflect a flexible view of learner preferences: learners differ, varied methods help, content can be represented in multiple ways, and differentiated tasks/grouping can be informed by preferences. Statement C is false because rigidly teaching only to a fixed label does not always improve learning, and F is false because objectives and difficulty remain important. Therefore, the correct set is A, B, D and E only, making option A the right answer.

Option A:
Option A includes A, B, D and E, all of which are accurate. It excludes C and F, which are incorrect. Hence A, B, D and E only is correct.

Option B:
Option B includes C (false), so A, B, C and D only cannot be accepted.

Option C:
Option C includes F (false), so A, B, D, E and F only is not valid.

Option D:
Option D includes F (false) and omits A, so B, D, E and F only is incorrect.

Option E includes C and F (false), so A, C, D and F only cannot be correct.

Option F includes C and F (false) and omits A and B, so C, D, E and F only cannot be correct.

Statements D and E are wrong because climate justice specifically criticises ignoring inequalities within countries and treats inter-generational equity as a central concern. Statements A, B, C and F are correct in emphasising historical responsibility, disproportionate impacts, capability-based equity and justice claims around loss and damage. Since exactly D and E misrepresent climate justice principles, the correct answer must identify both of them as wrong together.

Option A:
Option A is incorrect because it points only to D as wrong and overlooks E. By failing to mark E, which denies the link between climate justice and inter-generational fairness, it does not fully capture the ethical dimensions of climate debates.

Option B:
Option B is incorrect as it singles out E and leaves D unmarked. Statement D wrongly suggests that climate justice ignores within-country inequalities, which is contrary to the focus on marginalised groups in many justice frameworks.

Option C:
Option C is incorrect because it treats C as if it were wrong along with D and E. In fact, C correctly states that equitable climate policies take different capabilities and development needs into account, so including it among wrong statements makes this option conceptually flawed.

Option D:
Option D is correct since it identifies both D and E as the statements that contradict established notions of climate justice and equity. It implicitly recognises A, B, C and F as valid descriptions of responsibility, impact and justice claims, and therefore best matches the requirement to select the wrong statements.

The Green Credit Rules create a framework in which environmentally beneficial activities can earn “green credits” that are tradable in a domestic market. Activities such as tree plantation on degraded land, water conservation or pollution abatement can generate credits if they meet specified criteria. By attaching economic value to such actions, the programme seeks to encourage wider participation by individuals, communities and firms. It thus complements command-and-control regulation with market-based incentives aligned with sustainable development goals. (moefcc-gcp.in)

Option A:
This option is incorrect because the Green Credit Rules do not replace all environmental regulations; they operate alongside existing laws. A single carbon tax would also be much narrower than the multi-activity scope of the programme.

Option B:
This option is wrong as credits are earned only when specified environmental actions are undertaken and verified. The programme does not offer unconditional cash transfers but performance-linked incentives.

Option C:
This option correctly captures the intention of the scheme: to reward verifiable positive environmental actions with tradable credits. It highlights both the incentive structure and the focus on activities such as plantation and restoration.

Option D:
Allowing blanket conversion of forest land into real estate in exchange for credits would undermine conservation goals. The rules seek to support ecological improvement, not legitimise deforestation.

Statements A, B and D together present the intended features of the Academic Bank of Credits. A is correct because ABC is specifically designed to store credits from different recognised institutions. B is correct as ABC supports flexible entry and exit within approved programme structures. D is correct since regulations allow mobility of credits across modes such as online and offline programmes. C, E and F are incorrect because credits do not automatically expire within one semester, ABC is not limited to central universities alone, and it does not remove the need for institutional academic records.

Option A:
Option A is correct because it selects exactly A, B and D, all of which accurately describe accumulation, flexible use and mobility of credits through ABC, while excluding C, E and F which misstate expiry rules, eligibility and the role of institutional records.

Option B:
Option B is incorrect because it includes C, wrongly suggesting that credits expire automatically within the same semester, which contradicts the principle of long-term accumulation.

Option C:
Option C is incorrect because it includes E, which wrongly limits access to central university students, and omits B, thereby ignoring the role of ABC in enabling multiple entry and exit.

Option D:
Option D is incorrect because it includes F, which falsely claims that institutional student records are no longer needed, and omits A, so it fails to emphasise the core feature of credit accumulation from multiple institutions.

Statements A, B, D and E are all true and together describe a realistic picture of ICT-based teacher professional development. Online and LMS-hosted courses increase flexibility, while webinars and communities of practice widen professional networks. Blended models that mix online and face-to-face elements are widely used for sustained learning. Statement C is too extreme because online formats often complement rather than fully replace in-person interaction, and F is wrong because ICT-supported development is valuable across all subjects, so the correct combination keeps only A, B, D and E.

Option A:
Option A is correct because it includes all the statements that reflect flexible, networked and blended professional learning for teachers. It recognises that LMSs, online courses and communities enable continuous development while also acknowledging the legitimacy of blended formats. By excluding C and F, it avoids the claim that ICT removes all face-to-face needs or that only computer science teachers benefit from such programmes.

Option B:
Option B is incorrect because it includes C, which claims that ICT-based professional development always eliminates face-to-face interaction. In practice, programmes often retain workshops, mentoring or classroom observation alongside online components. The presence of this extreme statement makes the whole combination wrong even though A, B and D are correct.

Option C:
Option C is incorrect because it accepts F and omits A. While B and D are true, E is also true and F is false because ICT-based development is relevant for teachers of languages, science, arts and other disciplines. The combination also misses the explicit mention of flexible online courses in A, so it cannot be considered correct.

Option D:
Option D is incorrect because it adds F to the otherwise correct set A, B, D and E. Including F would imply that only computer science teachers need ICT-based development, ignoring the cross-curricular nature of digital pedagogy. This contradicts inclusive professional development policies, making the option invalid.

Modus tollens is a valid form of argument that denies the antecedent by denying the consequent of a conditional. It proceeds from “if p, then q” and “not q” to the conclusion “not p”. This preserves truth because if p were true, q could not be false. Therefore the pattern described in the stem is known as modus tollens.

Option A:
Option A, affirming the consequent, argues from “if p then q” and “q” to “p”. This pattern is invalid because q might be true for other reasons. Thus affirming the consequent is a fallacy, not the valid form in the question.

Option B:
Option B correctly names modus tollens as the rule that infers “not p” from “if p then q” and “not q”. It is a central tool in deductive proof and refutation. Hence this option accurately answers the question.

Option C:
Option C, denying the antecedent, moves from “if p then q” and “not p” to “not q”. This is also invalid because q could still be true for other causes. Therefore denying the antecedent cannot be the form intended by the stem.

Option D:
Option D, reductio error, is not a standard label for this precise conditional pattern. While reductio arguments sometimes use similar ideas, the technical name of the form in the question is modus tollens.

Statement C is the only wrong statement because it reverses the speed relationship between cache memory and hard disks. Cache memory is much faster and is used to speed up access to frequently used data. Statements A, B and D correctly describe RAM as volatile, ROM as non-volatile and secondary storage as including hard disks, SSDs and optical media. Hence, the correct answer is the option that selects only C as wrong.

Option A:
Option A is incorrect because it groups A and C as wrong statements. Statement A is actually true, as RAM is volatile primary memory storing currently active data and programs. Including a true statement as wrong makes this option conceptually flawed.

Option B:
Option B is incorrect because it treats B and C as wrong statements. While statement C is wrong, statement B correctly describes ROM as non-volatile memory. Combining a true statement with a false one in the wrong set does not satisfy the question.

Option C:
Option C is incorrect because it labels A, B and C as wrong. Both A and B correctly describe properties of RAM and ROM, and only C is incorrect. Since this option misclassifies true statements, it cannot be accepted.

Option D:
Option D is correct because it isolates statement C as the only wrong statement. It recognises that cache is actually faster than hard disks and therefore corrects the misleading comparison in the statement. By acknowledging A, B and D as correct, this option matches the logic of the question.

Statements A, B, C and E correctly describe features of mass communication, while D is incorrect. A is true because mass communication generally uses technological media such as television, radio or online platforms to address large and diverse audiences. B is true as feedback in mass communication is often delayed or indirect, making the flow largely one-way. C is true since media organisations and institutions typically act as communicators. E is true because gatekeeping refers to the editorial process of selecting and shaping content. D is wrong because mass communication does not “always” provide real-time personalised messages to each individual; such personalisation is limited and not a defining property, so D only is the wrong statement.

Option A:
Option A, which selects A and D only, mistakenly treats A as an incorrect statement even though it accurately reflects the technological and large-audience nature of mass communication. By including a true statement as wrong, this option becomes logically inconsistent. Therefore, A and D only cannot be accepted.

Option B:
Option B groups B, D and E as wrong, but both B and E are correct descriptions: B notes the limited immediate feedback common in mass communication, and E explains gatekeeping. Labelling these as wrong misrepresents mass media theory. Thus, B, D and E only is not a valid option.

Option C:
Option C singles out D only, correctly identifying the statement that exaggerates the degree of real-time personalisation in mass communication. Because all the other statements describe accepted features, isolating D as the sole wrong statement is accurate. Hence, D only is the correct answer.

Option D:
Option D treats C and D as wrong, but C is a correct observation that institutions, rather than lone individuals, usually function as communicators in mass media. Including C among wrong statements means this option cannot be reconciled with standard understanding of mass communication. Therefore, C and D only is not acceptable.

Statements A, B and C correctly summarise the classical three stages of the demographic transition model. High birth and death rates in the first stage, followed by declining death rates and continued high birth rates in the second stage, and eventually low birth and death rates in the third stage are well-established patterns. Statement D is incorrect because the model is used precisely to explain how development affects population dynamics and vice versa. Therefore, the combination containing A, B and C only is the correct answer.

Option A:
Option A is correct because it includes all three accurate descriptions of the stages of demographic transition and excludes the dismissive statement D. It preserves the conceptual link between development and changes in fertility and mortality patterns. By omitting D, it aligns with demographic theory widely discussed in UGC NET syllabi.

Option B:
Option B is incorrect because it adds D, which incorrectly states that the model is irrelevant to understanding development–population relationships. Since demographic transition is a central framework in population studies, including D contradicts the established use of the model.

Option C:
Option C is incorrect because it lists only A and B as correct, leaving out C, which accurately describes the third stage of low birth and death rates and near-stable population. Excluding a correct statement results in an incomplete representation of the model.

Option D:
Option D is incorrect because it includes D, implying that the model is irrelevant, and omits A, which is a foundational description of the first stage. Such a combination mischaracterises both the content and significance of demographic transition theory.

The expression 2^5 means 2 multiplied by itself five times, which gives 32. In a binary number, the bit in the 2^5 position therefore has a weight of 32. When that bit is set to 1, it contributes 32 to the decimal value of the number.

Option A:
Option A is correct because calculating 2×2×2×2×2 results in 32. This is a fundamental power of two frequently used in computing.

Option B:
Option B, 16, corresponds to 2^4, not 2^5. It therefore has a smaller weight than required.

Option C:
Option C, 64, is 2^6, which is one exponent higher than the requested position. It represents a larger place value than 2^5.

Option D:
Option D, 8, is equal to 2^3 and corresponds to a different bit position in a binary number. It cannot represent the value of the 2^5 place.

Renewable resources are replenished naturally on a human time scale, while non-renewable resources are finite and deplete with extraction. Solar energy is continuously supplied by the Sun and does not run out through human use. Coal, on the other hand, is a fossil fuel formed over millions of years and is exhausted when mined and burned. Thus, pairing solar energy as renewable with coal as non-renewable correctly illustrates the contrast between the two categories.

Option A:
Option A is incorrect because it lists two renewable resources together and does not provide a non-renewable counterpart. Although both solar and wind are renewable, the question asks for a renewable and a non-renewable pair.

Option B:
Option B is incorrect since coal and crude oil are both non-renewable fossil fuels. They do not demonstrate the contrast between resource types that the question seeks.

Option C:
Option C is correct because it combines one clearly renewable source, solar energy, with one clearly non-renewable source, coal. This makes the distinction between resource types easy to understand in the context of sustainable development.

Option D:
Option D is incorrect as natural gas and petroleum are both non-renewable fossil fuels. Like coal and crude oil, they are finite and formed over geological time spans.

Statements A, C and E correctly relate learning styles to teaching strategies. A is true because knowing how learners tend to engage can guide choice of activities. C is true since using a variety of approaches allows more learners to find an entry point into the content. E is true as combining visual, auditory and kinesthetic elements can make lessons richer. B, D and F are false because relying only on the teacher’s style, treating learning styles as the only factor or assuming learners can never adapt contradicts flexible instructional design; thus A, C and E only is correct.

Option A:
Option A contains A, C and E, all of which support responsive and varied teaching aligned with learner preferences. It excludes B, D and F, which promote rigid or oversimplified views of styles, so this option presents the correct set of statements.

Option B:
Option B groups A, E and F, but F wrongly asserts that learners cannot adapt to changed teaching, ignoring evidence that students can develop new strategies. Because it includes a false belief, A, E and F only cannot be accepted.

Option C:
Option C includes D, which says learning styles are the only factor to consider, even though objectives, content and context are also crucial. Hence C, D and E only mixes true and false statements and is invalid.

Option D:
Option D adds D to A and C, E, again treating learning styles as the sole planning factor, which misrepresents comprehensive lesson design. Therefore A, C, D and E only is not the correct combination.

A program encodes an algorithm in a form that can be understood and executed by a computer, producing desired outputs from given inputs. It may be written in languages such as C, Java or Python and must follow precise syntax rules. Programs form the basis of all application and system software. Therefore, the description in the stem refers to a computer program.

Option A:
Option A is correct because the standard definition of a program highlights it as a list of ordered instructions that direct a computer to perform tasks. This aligns exactly with the wording of the question.

Option B:
Option B, database, is an organised collection of data that programs can manipulate but is not itself a set of executable instructions.

Option C:
Option C, spreadsheet, is a type of application that contains programs within its functions but primarily serves as a user tool for calculations and data organisation.

Option D:
Option D, topography, relates to mapping physical terrain and has no direct connection with programming instructions.

Statements A, B, D and E accurately describe common features of collaborative document tools, while C and F are incorrect. Revision history and comments support transparent, iterative improvement, but do not guarantee error-free output. Offline sync broadens access, and flexible permissions control how participants interact with a document. Therefore, the combination A, B, D and E only is correct.

Option A:
Option A is incomplete because it leaves out E, thereby failing to acknowledge offline editing and later synchronisation—an important feature for users with intermittent connectivity.

Option B:
Option B is incomplete because it omits A, so it does not mention revision history and accountability for changes, which are central advantages of collaborative editing.

Option C:
Option C is correct because it groups all the true statements and excludes C’s claim about guaranteed perfection and F’s denial of integrations. It recognises collaborative tools as powerful yet still requiring human review.

Option D:
Option D is incorrect because it accepts F, which states that shared documents can never integrate with LMS or other systems. In practice, many platforms allow embedding or linking collaborative documents within course spaces.

The Physical Quality of Life Index was developed to measure development through basic human outcomes rather than income. It combines life expectancy, infant mortality rate and adult literacy rate into a single composite. These indicators reflect health and education conditions that directly affect people’s lives. Therefore, the option that lists life expectancy, infant mortality and literacy together correctly states the components of PQLI.

Option A:
Option A is correct because it focuses on survival and basic education, which are central to the idea of physical quality of life. By using these three, the index captures whether people live long, whether children survive and whether adults can read and write. The index deliberately excludes income so that attention remains on outcomes, not monetary means.

Option B:
Option B is incorrect because per capita income is not a part of PQLI; it is used in other indices like HDI or income-based measures. Introducing income would shift the focus away from the physical quality of life concept that PQLI was designed to highlight.

Option C:
Option C is incorrect since carbon emissions are environmental indicators and do not directly measure individual physical well-being. While relevant for sustainability, they are not one of the three PQLI components.

Option D:
Option D is incorrect because Gross Domestic Product and an environmental quality index are not included in PQLI. GDP measures economic output, and the index was designed partly to offer an alternative to such macroeconomic measures.
