UGC NET Questions (Paper – 1)

Statements A, B and D are correct, whereas C is incorrect. A is true because immediacy behaviours such as addressing students by name and showing interest can strengthen their sense of belonging. B is true since feeling close to the teacher often encourages students to ask questions and contribute. D is true as immediacy includes verbal actions like praise and non-verbal cues such as eye contact and open posture. C is false because aloof and distant behaviour generally reduces, rather than increases, student motivation.

Option A:
Option A is incorrect because it contains only A and B and omits D, failing to mention that both verbal and non-verbal actions form part of immediacy. Without D, the description of immediacy is incomplete. Therefore A and B only cannot be the correct answer.

Option B:
Option B is incorrect because it groups B and D only and leaves out A, overlooking the broader impact of immediacy on students’ sense of belonging to the class. Since A is also correct, B and D only is not a full representation of the concept.

Option C:
Option C is correct because it brings together A, B and D, the three statements that accurately connect teacher immediacy with student motivation and participation. It explicitly rejects C, which wrongly suggests that distance and aloofness raise motivation. Hence this option best matches the set of correct statements.

Option D:
Option D is incorrect because it treats all four statements as correct, including C. Since C promotes a view contrary to research on teacher immediacy, the presence of this false statement invalidates the combination.

In this series, the first letters are A, E, I, M, which correspond to positions 1, 5, 9 and 13, all increasing by 4. The second letters are D, H, L, P, i.e. positions 4, 8, 12 and 16, also increasing by 4. The next first letter after M (13) is Q (17) and the next second letter after P (16) is T (20). Hence QT is the only pair that continues the uniform +4 progression in both positions.

Option A:
Option A, QS, provides the correct first letter Q but gives S as the second letter, which is only 3 steps ahead of P. The series demands a constant increase of 4 positions for the second letter as well. Since S is inconsistent with the established step size, this option disrupts the pattern and is therefore incorrect.

Option B:
Option B is correct because Q and T are exactly 4 positions ahead of M and P respectively. This keeps the uniform step size intact for both components of the pair. By preserving the same arithmetic structure as in all previous terms, QT is the only option that maintains strict logical continuity in the series.

Option C:
Option C, QU, pushes the second letter forward to U, which is 5 positions after P. This overshoots the fixed increment and changes the rule mid-series. Since the first and second letters must follow the same step of +4, QU cannot be considered a valid continuation.

Option D:
Option D, QV, again uses the correct first letter Q but moves the second letter to V, which is 6 positions ahead of P. This introduces a larger increment than used before, breaking the constant-difference pattern that defines the sequence. Therefore option D does not fit the series.

Statements A, B, D and E are correct, whereas C and F are false. A and B correctly describe the distribution of subject and predicate in universal forms, and D correctly notes that O distributes only the predicate. E is right that A and O are contradictories in the traditional square. C is wrong because I distributes neither term, and F is wrong because modern (Boolean) logic does not usually treat universal statements as existentially loaded. Hence A, B, D and E only is the correct combination.

Option A:
Option A is incomplete because it omits E, which correctly identifies the contradictory relation between A and O. Although A, B and D are true about distribution, leaving out E makes the description of categorical relations less complete. Therefore A, B and D only cannot be accepted as the full set of correct statements.

Option B:
Option B is incorrect as it omits D and claims only A, B and E are correct. While A, B and E are true, ignoring the distribution property of O propositions means one correct statement is missing. As a result, this option does not capture all the true statements given.

Option C:
Option C is wrong because it does not include A and instead accepts B, D and E only. Omitting A removes the basic rule for distribution in A statements. Since A is clearly correct, any option that leaves it out fails to represent the entire set of true statements.

Option D:
Option D is correct because it groups A, B, D and E, all of which align with traditional categorical logic and the square of opposition. It excludes C, which overstates I’s distribution, and F, which misrepresents modern logic’s stance on existential import. Thus this option exactly matches the set of correct statements.

Statements A, B and D are correct, whereas C is incorrect. A is true because students’ perceptions of clarity and engagement provide valuable feedback for teachers. B is true since studying who speaks, for how long and in what patterns helps refine interaction strategies. D is true as peers can observe communication behaviours that the teacher may not notice. C is false because focusing only on exam scores ignores key process indicators of effective teaching, including communication quality.

Option A:
Option A groups A and B only and omits D, overlooking the role of peer observation in providing structured feedback on communication. Without D, the evaluation framework is narrower than it should be. Therefore A and B only cannot be accepted.

Option B:
Option B includes B and D only and leaves out A, ignoring the direct voice of students regarding clarity and effectiveness. Since A is also a correct statement, B and D only does not capture all relevant evidence sources. Hence this option is incomplete.

Option C:
Option C brings together A and D only but omits B, missing the analytical dimension of classroom interaction patterns. Because B is correct, A and D only does not present the full set of accurate statements. Thus it is not valid.

Option D:
Option D combines A, B and D and excludes C, which wrongly discounts communication evidence in teaching evaluation. This option recognises student feedback, interaction analysis and peer observation as complementary sources. As it contains all and only the correct statements, A, B and D only is the right answer.

Biochemical Oxygen Demand measures the amount of dissolved oxygen required by microorganisms to decompose organic matter in water. A high BOD value means that microbial activity will consume large amounts of oxygen, which can deplete DO levels and stress aquatic life. Such conditions are typical of water polluted with sewage or other organic wastes. Therefore, a high BOD value indicates high biodegradable organic load and probable pollution, making Option B correct.

Option A:
Option A is incorrect because very clean water with low organic pollution would show low BOD values. High BOD is a sign of high organic content, not cleanliness.

Option B:
Option B is correct as it links high BOD to high organic matter and likely pollution. This interpretation underlies regulatory standards for effluent discharge and river water quality classification.

Option C:
Option C is incorrect since the presence of organic matter and high BOD implies active microbial populations, not their absence. Microorganisms are responsible for consuming oxygen as they break down waste.

Option D:
Option D is incorrect because chemically pure drinking water should have low BOD, indicating minimal organic contamination. High BOD water generally requires treatment before it is safe to drink.

Sāmānyatodṛṣṭa anumāna involves inference based on general patterns of co occurrence rather than a clear temporal order of cause and effect. Movement of leaves is regularly associated with the presence of air or wind, even though air itself may not be directly perceived. From this generally observed relation, one infers air from leaf movement. Nyāya uses such examples to illustrate inference to entities known only through their effects.

Option A:
Option A, pūrvavat, describes inference from present cause to future effect, as when dark clouds lead us to expect rain.

Option B:
Option B, śeṣavat, is often used for inferring an unperceived cause from a known effect in a more definite causal chain, as in inferring fire from smoke.

Option C:
Option C correctly classifies the case as sāmānyatodṛṣṭa, where broad, repeated association lets us infer something unseen like air from an observable sign.

Option D:
Option D, kevalānvayi, refers to inference where only positive instances exist and no genuine negative instances are available, which is not the key feature of this example.

Green computing emphasises designing, using and disposing of computer systems in ways that minimise environmental impact. This includes energy efficient hardware, power management features and responsible recycling of electronic waste. Organisations adopt green computing to reduce costs, comply with regulations and support sustainability goals. Thus, the computing approach described is green computing.

Option A:
Option A, ubiquitous, computing focuses on embedding computation into everyday objects and environments and does not inherently address environmental responsibility.

Option B:
Option B is correct because the term green computing is widely used to denote eco friendly practices in the ICT domain, directly matching the concern for responsible and efficient use.

Option C:
Option C, mobile, computing relates to computing on portable devices and is defined by mobility rather than environmental considerations.

Option D:
Option D, embedded, computing deals with specialised processors inside appliances and machines, which may or may not be designed with green principles in mind.

This sequence follows the rule aₙ = n³+2n for n starting from 1. For n = 1, 2, 3, 4 and 5 we obtain 1³+2 = 3, 2³+4 = 12, 3³+6 = 33, 4³+8 = 72 and 5³+10 = 135, matching the given terms. For n = 6 the formula gives 6³+12 = 216+12 = 228. Therefore 228 is the only value that continues the same cubic relationship without any adjustment.

Option A:
Option A, 218, does not equal n³+2n for n = 6 and would require subtracting 10 from the value given by the formula. This distortion breaks the clear pattern connecting each term to its index. Thus 218 cannot be regarded as the correct next term.

Option B:
Option B, 222, is still below the correct cubic value of 228 and does not satisfy the rule aₙ = n³+2n. It represents an arbitrary modification rather than a logical extension of the pattern. For this reason it is not the right answer.

Option C:
Option C, 228, is precisely the value obtained from the generating rule when n = 6. It respects the same algebraic structure used for all earlier terms and keeps the series internally consistent. Hence 228 is the correct continuation.

Option D:
Option D, 236, exceeds the formula’s prediction and has no basis in the expression n³+2n for the next index. Adopting 236 would undermine the transparent cubic pattern, so it is not a valid option.

Statements A, B, C and E correctly describe the truth-table method for testing validity, while D is false. Validity depends on what happens in all rows where premises are true: if the conclusion is always true in those rows, the argument form is valid; if there is even one row with true premises and a false conclusion, the form is invalid. We therefore must systematically inspect all such rows, not just one arbitrarily chosen row. In UGC NET, many candidates reason through small tables mentally, illustrating E.

Option A:
Option A is incomplete as it omits E, not acknowledging that mental truth-table reasoning is often used in the exam. A, B, C only therefore does not fully incorporate the exam-oriented aspect of the question.

Option B:
Option B is wrong because it leaves out C, neglecting the explicit description of the counterexample row that makes a form invalid. A, B, E only thus fails to give the full condition for invalidity.

Option C:
Option C is correct since it combines the method for finding rows with true premises, the criteria for validity and invalidity, and the exam practice of mental truth tables while excluding D. It reflects standard teaching and UGC NET expectations.

Option D:
Option D is incorrect because it omits A and claims that inspecting only one arbitrary row is sufficient, which contradicts the requirement to check all rows where premises are true. B, C, E only therefore cannot be correct.

Each term is a block of four consecutive letters written in reverse order, and the starting letter moves forward by four positions each time. The starting letters D, H, L and P have positions 4, 8, 12 and 16, all increasing by 4. The next starting letter is position 20, which is T, and writing the four letter block from T in reverse gives TSRQ. This preserves both the plus four progression and the internal reverse arrangement.

Option A:
Option A, RQPO, rearranges letters including P and O but does not start with the correct letter T. It also breaks the strict descending order that characterises each block. Since it fails to follow the formula for the starting position and the internal structure, RQPO is not consistent with the pattern.

Option B:
Option B, SRQP, begins with S instead of T, which is only three positions ahead of P, not four. This changes the size of the jump in starting letters and disrupts the regularity of the sequence. Additionally, the letter order within the block does not correspond to a straightforward reverse of four consecutive letters starting at T.

Option C:
Option C, QPON, reverses the internal order of letters found around P but again starts with Q, not T, and does not reflect the plus four movement. It also returns to letters that are two positions behind P, which contradicts the forward movement of starting positions. Because it fails on both structural and positional grounds, QPON is not the correct continuation.

Option D:
Option D is correct because T is four positions after P and TSRQ lists T, S, R and Q as consecutive letters in descending order. It exactly mirrors the format of earlier blocks, which all reverse a run of four consecutive letters. This consistent adherence to both the starting letter progression and the reverse order makes TSRQ the valid next term.

The phrase used in NEP 2020 is “light but tight,” meaning that regulation should be limited in quantity but strict in enforcement. “Light” refers to reducing unnecessary rules and intrusive control, while still maintaining strong oversight on core quality aspects. Hence, “light” is the correct completion.

Option A:
Option A is correct because the policy explicitly calls for fewer but clearer regulations, trusting institutions in day-to-day matters while keeping oversight tight on academic standards and integrity.

Option B:
Option B is incorrect since “heavy” would indicate many rules and detailed micromanagement, which the policy seeks to move away from.

Option C:
Option C is wrong because “weak” regulation would imply lax enforcement, contradicting the “tight” part of the phrase that stresses strong compliance and accountability.

Option D:
Option D is incorrect as “rigid” suggests inflexible and possibly excessive regulation, again at odds with the idea of keeping the framework light in terms of the number of regulations.

In an argument, the conclusion is the main claim that the author wants the reader to accept on the basis of supporting reasons. Here, the factual observation about students who attend regularly and score high functions as the evidence. From this observation, the writer infers a general statement about the role of regular attendance in academic success. That generalised statement is what the premises are intended to support, so it is the conclusion.

Option A:
Option A presents the general claim that is being supported by the preceding observation, not the observation itself. It captures the “therefore” part of the reasoning and summarises the main point the argument is trying to establish.

Option B:
Option B reports the empirical basis of the argument and therefore functions as a premise, not the final point to be proved.

Option C:
Option C adds the stronger claim that success always requires attendance, which goes beyond the stated conclusion and is not actually asserted.

Option D:
Option D introduces a claim about marks being the only sign of success, which is not mentioned in the argument and cannot be its conclusion.

Statements A, B and C correctly describe the three levels of teaching: memory level stressing recall, understanding level emphasising meaningful learning and application, and reflective level involving problem-solving and critical thinking. Statement E is also correct because moving from memory to reflective level indicates progression from simple recall to complex, higher-order cognitive processes. Statement D is false because the learner has an increasingly active role at understanding and reflective levels. Therefore A, B, C and E only is the correct combination of statements.

Option A:
Option A includes A, B and C, all of which are true, but omits E, which correctly characterises the shift to higher-order thinking. Excluding a true statement makes the combination incomplete and therefore not acceptable.

Option B:
Option B groups B, C and E and leaves out A, even though memory level teaching and its focus on recall are an important part of the overall framework. Without A, the set does not fully represent all three levels, so this option is not correct.

Option C:
Option C contains A, B, C and E, each accurately reflecting a feature of the levels of teaching and their cognitive demands. It excludes D, which incorrectly portrays the learner as always passive. Because it includes all and only the true statements, this option is correct.

Option D:
Option D brings together A, C and E but omits B, so the description of understanding level teaching is missing. This results in a partial and therefore inadequate account of the levels of teaching.

Option E includes A, B, D and E and accepts D as if it were true, wrongly claiming that learners are completely passive at all levels. The presence of this false statement invalidates the option.

NEP 2020 expects school complexes to function as academic hubs that coordinate joint CPD, peer learning and resource sharing among teachers from different schools.

Option A:
This option is incorrect because limiting complexes to infrastructure sharing misses their intended academic and professional-development role.

Option B:
This option is correct; it matches NEP’s idea of complexes organising workshops, collaborative planning and exchanges of good practice.

Option C:
This option is wrong because handling only admissions is a narrow administrative task and not the main function of complexes.

Option D:
This option is incorrect since using complexes solely as exam centres ignores their continuous improvement responsibilities.

Statements A, B, C and F correctly describe vyāpti in Indian logic, while D and E are false. Vyāpti captures the necessary connection between hetu and sādhya discovered through repeated observation and the ruling out of counterinstances. Nyaya treats this relation as the essential ground of any valid inference, and the smoke–fire example is frequently used in teaching and exams. D is wrong because a single coincidence does not establish invariable concomitance, and E is wrong because Nyaya does not regard vyāpti as purely a priori; empirical observation and reasoning are both involved.

Option A:
Option A is incomplete since it omits F, leaving out the specific exam-oriented reference to the smoke–fire example that often illustrates vyāpti. While A, B and C are true, they do not fully reflect how the concept is used pedagogically. Therefore A, B and C only is not entirely adequate.

Option B:
Option B is incorrect because it includes D, which claims that one accidental co-occurrence is enough to secure vyāpti, contradicting the insistence on repeated, exceptionless observation. Including D invalidates the combination. Hence A, B, C and D only cannot be accepted.

Option C:
Option C is correct because it gathers the core definitional and methodological points along with the common example used in UGC NET materials, while excluding D and E, both of which misrepresent the nature of vyāpti. Thus A, B, C and F only is the right answer.

Option D:
Option D is wrong as it omits A and includes only B, C and F, leaving out the very definition of vyāpti as invariable concomitance. Without A, the candidate would not know what relation is being discussed. Therefore B, C and F only cannot be the correct choice.
