UGC NET Questions (Paper – 1)

Statements B, C and D correctly describe how higher education supports a knowledge society. B is true because universities and colleges produce research, generate skilled graduates and disseminate advanced knowledge. C is correct as ICT and digital platforms accelerate the production and spread of information. D is also true since knowledge societies depend on continuous upskilling and lifelong learning. A is false because higher education is central, not marginal, to innovation and development in a knowledge-based order. Thus the right combination is B, C and D only.

Option A:
Option A is incorrect because it includes only B and C and omits D, which highlights lifelong learning as a core characteristic of knowledge societies. Without D, the description remains partial.

Option B:
Option B is correct because it collects all three valid statements and excludes A, which wrongly minimises higher education’s role. The option therefore captures research, technology and lifelong learning as interlinked dimensions of a knowledge society.

Option C:
Option C is incorrect because it selects only C and D and leaves out B. Neglecting the institutional role of higher education in producing research and skilled manpower weakens the explanation of how a knowledge society functions.

Option D:
Option D is incorrect because it treats all four statements as correct and would thereby accept A’s claim that higher education is marginal. Since this contradicts the centrality of higher education in a knowledge economy, the option is invalid.

Under CBCS, one theory credit is typically linked to one contact hour per week (i.e., one hour of teacher–student instructional interaction). This link helps quantify student workload and align time with credit allotment. Hence, “contact” hours correctly complete the statement.

Option A:
Vacation hours refer to breaks when formal classes are not held. They do not form the basis for calculating credits and remain outside the teaching-learning schedule. Thus, this option is not correct.

Option B:
Examination hours matter for assessment, but CBCS credit definitions are primarily tied to regular instructional engagement (contact hours), not only to final tests. Therefore, this option is not correct.

Option C:
Library hours involve self-study and resource use, which are valuable but are not the standard unit used to assign credits for a theory course. Consequently, this option does not match the usual CBCS basis.

Option D:
Contact hours directly measure structured teaching-learning time between teachers and students. This is the commonly used basis in CBCS for assigning theory credits, which is why this option is appropriate.

COP27 concluded with governments agreeing to set up dedicated funding arrangements for loss and damage, including a new fund. This was significant because vulnerable countries had demanded such a mechanism for decades to help them cope with climate impacts that go beyond adaptation, such as devastating floods, storms and sea-level rise. The decision recognises historical responsibility and the need for solidarity with those least responsible for emissions yet hardest hit. It is therefore described as a milestone for climate justice in multilateral climate negotiations. (UNEP - UN Environment Programme)

Option A:
Option A is incorrect because the loss and damage discussions were not about subsidising fossil fuel exploration, which would worsen climate risks. Linking the new fund to exploration goes against the mitigation and justice objectives that shaped the COP27 outcome. This option reverses the actual intent of the decision.

Option B:
Option B is correct as it accurately summarises the COP27 decision to establish funding arrangements, including a loss and damage fund, targeted at particularly vulnerable countries. It captures both the creation of a new mechanism and its focus on addressing unavoidable climate harms. This aligns with official texts and with how media and experts described the outcome.

Option C:
Option C is wrong because COP27 did not cancel climate finance commitments; in fact, it reiterated the need for scaled-up support. Ending such obligations would undermine trust between developed and developing countries and contradict the overall direction of negotiations.

Option D:
Option D is incorrect since the Paris Agreement remains in force, and COP27 decisions operate within its framework. While adaptation received attention, it was not the sole focus, and no replacement treaty was adopted.

A sufficient condition is one whose presence ensures that a specified event will occur. Whenever the sufficient condition holds, the event must follow. However, the event might also occur due to different sufficient conditions. Thus the description of a guarantee in the stem accurately captures the idea of a sufficient condition.

Option A:
Option A, incidental, suggests something that occurs by chance or as a side effect. Incidental factors do not reliably guarantee outcomes. Therefore incidental is not the logical term indicated by the question.

Option B:
Option B, necessary, refers to a condition that must be present but may not by itself produce the event. Necessary conditions do not guarantee occurrence when considered alone. Hence necessary is not the correct answer here.

Option C:
Option C correctly identifies sufficient as the type of condition whose presence is enough to ensure the event. This concept is central to understanding causal and logical relationships. Therefore sufficient condition is the best match for the stem.

Option D:
Option D, remote, implies distance or weak connection and has no precise meaning in standard conditional analysis. A remote factor need not guarantee an outcome. Consequently remote is not suitable as an answer.

Mission LiFE is designed as a people-centric movement that nudges individuals and communities towards sustainable everyday choices. It emphasises reducing wasteful consumption of energy, water and materials, and encourages habits such as reuse, repair and sharing. By framing citizens as “Pro Planet People”, it links climate and environmental goals directly with development and well-being. (MyGov.in)

Option A:
This option correctly captures LiFE’s focus on lifestyle and behaviour change as a tool for climate action and sustainable development. It recognises that reducing wasteful consumption lowers environmental footprints without denying people a good quality of life.

Option B:
This option is incorrect because LiFE does not advocate expanding coal; instead, it seeks to reduce carbon-intensive consumption patterns that drive fossil fuel demand.

Option C:
Cash transfers are not the core instrument of LiFE; the initiative focuses on awareness, nudges and enabling green choices rather than general income support.

Option D:
Replacing environmental laws with voluntary corporate codes would weaken regulation, whereas LiFE is meant to complement, not substitute, formal environmental governance.

Statements A, C, D and F are correct, whereas B and E are incorrect. A standard categorical syllogism has three propositions involving exactly three distinct terms, and validity requires that the middle term be distributed at least once. Two negative premises cannot yield a valid conclusion because they fail to establish a positive link between the major and minor terms. Venn diagrams are widely used in reasoning questions to test such syllogisms visually. By contrast, B wrongly claims four terms, and E misstates the relationship between universal premises and the quantity of the conclusion. Therefore A, C, D and F only is the correct combination.

Option A:
Option A is incorrect because it omits F, leaving out the important fact that Venn diagrams are a recognised tool for checking validity. While A, C and D are true, the absence of F means this option does not contain all correct statements. Hence A, C and D only cannot be accepted.

Option B:
Option B is wrong since it includes E as though it were correct. E claims that universal premises always force a particular conclusion, but some valid moods, like Barbara, produce universal conclusions. Including this false rule makes the combination logically unsound.

Option C:
Option C is correct because it groups A, C, D and F, capturing the structural features and testing method of categorical syllogisms. It excludes B, which inflates the number of terms, and E, which oversimplifies the quality-quantity relations. Thus this option matches the genuine rules of classical syllogistic logic.

Option D:
Option D is incorrect because it accepts E as well as C, D and F while omitting A. Leaving out A ignores the three-proposition nature of syllogisms, and including E introduces a faulty generalisation about conclusions. Therefore C, D, E and F only cannot be the right answer.

A correct understanding of ICT requires distinguishing between the tangible components and the logical instructions. Hardware includes parts like the CPU, monitor, keyboard and hard disk that can be physically touched. Software consists of operating systems and application programs that direct the hardware to perform tasks. This distinction is fundamental for basic computer literacy and system understanding.

Option A:
This option incorrectly limits hardware to external devices such as mouse or printer, ignoring internal components like CPU and motherboard. It also narrows software to internal memory, which is actually a hardware component. Therefore, it confuses important categories and does not provide a correct distinction.

Option B:
This option merges hardware and software concepts and restricts them only to storage devices, such as hard disks or pen drives. Storage is just one function among many in a computer system. Hence, the option is incomplete and conceptually inaccurate.

Option C:
This option wrongly identifies whatever appears on the screen as hardware, although the display content is generated by software. Hardware is the physical monitor, not the images on it. Referring to software as only “hidden background processes” ignores user-facing programs and gives a misleading view.

Option D:

Statements A, B, D and F present the accepted view of vocational integration. A is true because policies encourage offering vocational courses within HEIs. B is true since vocational courses can be credit-bearing and lead to awards. D is true as industry collaboration ensures relevance of curriculum and training. F is true because apprenticeships, internships and field work are typical vocational components. C is false: vocational education can enrich multidisciplinary learning, and E is false because universities and colleges are explicitly encouraged to host such programmes.

Option A:
Option A is incorrect because it omits F, thus ignoring the characteristic feature of work-based learning as part of vocational programmes.

Option B:
Option B is incorrect because it includes C, which wrongly suggests that vocational education conflicts with multidisciplinary education, and therefore mixes a false statement with correct ones.

Option C:
Option C is incorrect because it includes E, which prohibits offering vocational courses within universities, and therefore contradicts the integrated model envisaged in policy.

Option D:
Option D is correct as it selects A, B, D and F, all of which support integrated, credit-bearing, industry-linked and work-based vocational education, while excluding C and E, which portray it as separate or incompatible.

Hetu is the term used for the inferential mark or reason that is known to be invariably associated with the probandum. Its presence in the paksha licenses the move to the conclusion, as when smoke functions as hetu for fire on the hill. A proper hetu must satisfy conditions ensuring its reliability. Thus the reason described in the stem is called hetu.

Option A:
Option A, vyapti, is the underlying universal concomitance between hetu and sadhya, not the particular instance observed in the paksha. It is a general relation rather than the concrete reason present in the subject.

Option B:
Option B is correct because hetu is explicitly defined as that which, being pervaded by the sadhya, serves as the logical ground for inference. Without hetu there would be no inferential step from paksha to sadhya.

Option C:
Option C, drstanta, is the illustrative example used to show the vyapti, like a kitchen where smoke and fire co-occur. It supports the argument but is distinct from the reason stated in the paksha.

Option D:
Option D, prameya, is the object of knowledge in general, not specifically the middle term of an inference.

Statements A, B, C and E correctly outline the nature and importance of coding and classification. Coding converts raw responses into analysable symbols, schemes should cover all possibilities without overlap, open-ended responses often need inductively developed categories and careful coding minimises error. Statement D is false because altering answers to achieve symmetry violates data integrity and leads to misleading results. Therefore, the combination including A, B, C and E but excluding D is correct.

Option A:
Option A includes A, B and C but omits E, thereby failing to state explicitly that precise coding contributes to error reduction and accurate analysis. Without E, the rationale for investing effort in careful coding is not fully conveyed.

Option B:
Option B contains B, C and E but leaves out A, so it does not mention the fundamental step of assigning symbols or numbers to responses. This omission makes the description of coding incomplete, even though the other points are true.

Option C:
Option C is correct because it brings together all four true statements, emphasising both the procedures and the benefits of systematic coding and classification. It rightly excludes D, which suggests unethical alteration of responses.

Option D:
Option D includes A, C and E but omits B, ignoring the requirement that categories be exhaustive and mutually exclusive. Without that requirement, coding categories could overlap or leave gaps, so this option is incomplete.

For two positive integers a and b, the product a × b equals HCF(a, b) × LCM(a, b). Here, one number is 24, the HCF is 6 and the LCM is 72. Let the other number be n. Then 24 × n = 6 × 72. The right-hand side is 432, so n = 432 ÷ 24 = 18. Hence, the other number must be 18 to maintain both the given HCF and LCM.

Option A:
Option A, 12, would give 24 × 12 = 288, and since 6 × 72 = 432, the product condition would fail. It also changes the LCM and HCF relationship.

Option B:
Option B satisfies 24 × 18 = 432, matching 6 × 72 exactly. It ensures the pair of numbers has the stated HCF and LCM by the standard product relation.

Option C:
Option C, 36, gives a product of 864, which would require a different LCM or HCF than those given.

Option D:
Option D, 48, yields an even larger product and is inconsistent with the specified values of 6 and 72.

Option D – psychomotor domain The psychomotor domain focuses on skillful bodily movement and coordination, often requiring practice and demonstration. Performing a laboratory experiment involves handling apparatus, following procedural steps and controlling fine motor actions. These tasks depend heavily on motor skills in addition to conceptual understanding. Therefore, the objective in the stem belongs mainly to the psychomotor domain.

Option A:
Cognitive domain covers mental skills involving knowledge, comprehension and reasoning. While understanding the theory behind an experiment is cognitive, the act of physically carrying it out is primarily psychomotor. Thus, cognitive domain alone does not best describe the performance objective.

Option B:
Affective domain deals with attitudes, interests and values, such as developing appreciation for scientific inquiry. Although a positive attitude may encourage careful lab work, the core demand of the objective is accurate performance, which is skill-based rather than emotional. Hence, affective is not the correct domain here.

Option C:
Social domain, when emphasized, relates to how learners interact with others and function in groups. Group work may occur in laboratories, but the stated objective is to perform the experiment accurately, not to cooperate with peers. Consequently, the social domain does not capture the main focus of the objective.

Option D:
Psychomotor domain includes objectives like assembling equipment, manipulating instruments and executing procedures precisely, all of which are central to laboratory performance. Because the stem stresses accurate performance of an experiment, this option correctly identifies the relevant learning domain.

The series is generated by the polynomial rule aₙ = n⁴ + 6n with n starting from 1. Substituting n = 1, 2, 3, 4 and 5 gives 7, 28, 99, 280 and 655, which exactly matches the given terms. Applying the same expression for n = 6 gives a₆ = 6⁴ + 6·6 = 1296 + 36 = 1332. Therefore 1332 is the only value that continues this polynomial pattern without changing the underlying rule.

Option A:
Option A gives 1332, which is exactly the value obtained from the formula n⁴ + 6n for n = 6. It maintains the same relationship between the index and term that produced all earlier numbers. Because no adjustment or exception is needed at the sixth term, this option correctly extends the series.

Option B:
Option B, 1308, is 24 less than the value predicted by n⁴ + 6n at n = 6. To accept 1308 we would have to reduce the correct polynomial result only at the last step, which contradicts the exact agreement seen for the first five terms. Hence this option does not respect the established pattern.

Option C:
Option C, 1320, is still below the correct value and cannot be obtained from n⁴ + 6n when n = 6. It represents a near but inaccurate approximation that breaks the strict algebraic rule behind the sequence. For a UGC NET numerical reasoning item, such a deviation means this option must be rejected.

Option D:
Option D, 1344, is 12 greater than the formula’s output and likewise cannot be produced by the same rule at n = 6. Choosing 1344 would introduce an unexplained increase in the last term, destroying the consistency of the pattern. Therefore this option is not a valid continuation of the number series.

In positional number systems, single digits from 0 up to base minus one share the same numeric meaning across bases. In octal, digit '5' therefore represents the quantity five, just as it does in decimal. The difference lies in how multi-digit numbers are interpreted, not in the meaning of a standalone digit.

Option A:
Option A, 3, would correspond to the digit '3', not '5'. There is no reason for '5' to map to a smaller value in octal.

Option B:
Option B, 4, is likewise associated with the digit '4'. Octal does not remap the meanings of the basic digits 0 through 7 when they appear alone.

Option C:
Option C is correct because a single octal digit '5' has the same magnitude as decimal 5 when considered in isolation. The positional context only becomes important when digits combine.

Option D:
Option D, 6, would be the value of octal digit '6', not '5'. Changing the meaning like this would break consistency across number systems.

Differentiated instruction is an approach in which teachers vary content, process, products or learning environments to address learners’ readiness, interests and profiles. Within one lesson, students may work on different tasks or receive varying levels of support. The goal is to ensure that all learners can access the curriculum meaningfully. Therefore, designing different tasks and supports in the same lesson is called differentiated instruction.

Option A:
Differentiated instruction acknowledges that students do not learn in the same way or at the same pace. By planning varied materials and supports, teachers respond to individual needs while maintaining common learning goals. This matches the stem’s description of tailoring tasks, materials and support for diverse learners.

Option B:
Uniform instruction assumes that all students should receive the same content, tasks and pacing regardless of differences. This can lead to some learners being bored and others overwhelmed. Because the stem highlights variation within a single lesson, uniform instruction does not fit.

Option C:
Standardized instruction typically refers to highly prescribed content and methods designed to be the same across many classrooms. It minimizes teacher discretion to adapt to local differences. This approach runs counter to the flexibility implied in differentiated instruction.

Option D:
Convergent instruction might focus on bringing students to the same answer or understanding through similar routes. It does not necessarily involve providing varied tasks and supports tailored to individual needs. Therefore, it does not accurately capture the practice described in the question.
