UGC NET Questions (Paper – 1)

Statements A, B and D correctly describe examination reforms. Continuous assessment reduces dependence on a single final exam, diverse methods capture different dimensions of learning and alignment with outcomes ensures assessment matches intended learning. Statements C, E and F are false because reforms do not abolish all written exams, apply beyond professional programmes and can benefit from student feedback.

Option A:
Option A is incorrect because it omits D and therefore misses the outcome-alignment principle.

Option B:
Option B is incorrect because it omits A and therefore misses the role of continuous assessment in reducing high-stakes dependence.

Option C:
Option C is correct because it includes A, B and D and excludes C, E and F.

Option D:
Option D is incorrect because it includes E (false) and omits B (true), so it is not the correct combination.

For an n-bit unsigned integer, the maximum representable value is 2ⁿ − 1. With 10 bits, this becomes 2¹⁰ − 1 = 1024 − 1 = 1023. This value corresponds to the bit pattern of ten ones in binary, 1111111111₂. Thus, 1023 is the highest decimal number that fits in 10 unsigned bits.

Option A:
Option A follows the standard formula for unsigned range and correctly computes 2¹⁰ − 1 as 1023. It matches the idea that the all-ones pattern is the largest representable value in a fixed-width binary system. Therefore, this option is accurate.

Option B:
Option B, 1024, equals 2¹⁰ itself and would need 11 bits (1 followed by ten zeros) for representation. It lies just outside the range of 10-bit patterns, so it is not representable as a maximum with 10 bits.

Option C:
Option C, 511, is the maximum value for 9-bit unsigned representation (2⁹ − 1). Using it for 10 bits ignores the additional capacity provided by the extra bit. Thus, it underestimates the possible maximum.

Option D:
Option D, 512, is 2⁹ and would require at least 10 bits, but it is not the maximum of the 10-bit range. Higher values up to 1023 are possible, so 512 does not exhaust the 10-bit unsigned capacity.

Collaborative learning involves students working together in small groups to achieve common learning goals. They share ideas,divide tasks and support each other’s understanding. Encouraging cooperative group work is a direct example of this approach. Therefore,the type of learning promoted in the stem is collaborative learning.

Option A:
Competitive learning environments emphasise outperforming others and often limit sharing of ideas,which is opposite to cooperative group work.

Option B:
Collaborative learning values joint responsibility and mutual support rather than solitary effort,which fits the teacher’s encouragement of group work described in the question.

Option C:
Individualistic learning stresses working alone on tasks and being evaluated independently without much peer interaction.

Option D:
Rote learning focuses on memorisation and repetition without meaningful collaboration or discussion.

Statements A, B, D and E correctly express key principles of inclusive classroom teaching. A and B emphasise viewing diversity as a resource and providing reasonable accommodations, which are central to inclusion. D and E highlight collaboration with stakeholders and creating a respectful, belonging-oriented classroom climate. C is incorrect because inclusive education advocates placement in regular schools with support, not segregation as the first option, and F is wrong because inclusion covers all forms of diversity, not just physical disabilities. Therefore, the set of correct statements is A, B, D and E only, making option B the right answer.

Option A:
Option A includes A, B and D, all of which are correct statements, but it leaves out E, which also accurately describes inclusive classrooms promoting respect and belonging. By omitting one true statement, this combination is incomplete and does not capture the full set of correct statements. Hence A, B and D only cannot be the correct answer.

Option B:
Option B contains exactly A, B, D and E, each of which correctly reflects inclusive values such as recognising diversity, providing accommodations, collaborating with support systems and fostering a sense of belonging. It excludes C and F, which wrongly limit inclusive education to segregated settings or only to physical disabilities. Because it includes all and only the true statements, A, B, D and E only is the correct combination.

Option C:
Option C adds F to A, B and E but omits D, and F wrongly claims that inclusive education applies only to physical disabilities. The presence of F, a false statement, and the absence of D, a true statement about collaboration, make this option logically inconsistent. As a result, A, B, E and F only cannot be the correct answer.

Option D:
Option D includes B, D, E and F, but F is false since inclusion addresses multiple forms of diversity such as cognitive, socio-economic and linguistic differences. Leaving out A, which is true, further weakens the accuracy of this set. Therefore B, D, E and F only is not a valid answer.

Option E brings in C alongside A, D and E, but C misrepresents inclusive education by advocating segregation as the first step. It also excludes B, which is a true statement about reasonable accommodations. Because it mixes a false statement with true ones and omits another true statement, A, C, D and E only cannot be accepted.

Option F groups C, E and F, but both C and F are false statements that contradict the principles of inclusive education. Only E is accurate, so this combination is dominated by incorrect ideas about segregation and narrow forms of diversity. Hence C, E and F only cannot represent the correct set of statements.

Statements A, B, C, E and F are correct: agronomic adjustments (dates/varieties), diversification, climate information, water-saving irrigation and extension services all support adaptation. Statement D is false because smallholders are often highly vulnerable and central targets of adaptation. Hence, the correct combination is A, B, C, E and F only.

Option A:
Option A is incorrect because it omits F, missing the crucial role of extension in spreading adaptation practices.

Option B:
Option B is correct because it includes all true statements and excludes D, which wrongly limits adaptation relevance to large farms.

Option C:
Option C is incorrect because it omits A, which is a valid and common adaptation measure (adjusting sowing dates/varieties).

Option D:
Option D is incorrect because it omits B, so it underrepresents diversification as a key risk-reduction strategy.

The rule states that each letter is replaced by its position in the alphabet and then all positions are summed. For NET, N is 14, E is 5 and T is 20. Adding these values gives 14 + 5 + 20 = 39. Since this computation matches the coding rule used in the example, 39 is the correct code for NET.

Option A:
Option A, 35, would require the sum of letter positions to be 35, but 14 + 5 + 20 clearly equals 39, not 35. This option therefore underestimates the actual total and ignores the correct arithmetic.

Option B:
Option B, 37, is also inconsistent with the required sum of positions, as there is no combination of N, E and T that would legitimately produce 37 under the stated rule. It likely arises from a miscalculation.

Option C:
Option C, 38, is again close to the correct answer but still incorrect because the precise sum 14 + 5 + 20 equals 39. In coding questions, even a small deviation from the rule’s outcome invalidates the option.

Option D:
Option D, 39, exactly matches the sum of the alphabetic positions of N, E and T. It faithfully applies the same coding procedure that produced 60 for WORD, making it the only option consistent with the defined rule.

Inclusive use of ICT aims to remove barriers so that learners with diverse abilities can participate fully in education. Assistive technologies and accessible design practices are central to this approach. They embody the principle of education for all. Therefore, the example given shows inclusive use of ICT.

Option A:
Option A is correct because inclusive accurately captures the intention to accommodate and support learners with disabilities through technology.

Option B:
Option B, competitive, emphasises rivalry and does not address accessibility concerns.

Option C:
Option C, exclusive, suggests shutting out certain groups, which contradicts the aim of the described practices.

Option D:
Option D, punitive, relates to punishment and has no connection with assistive technologies.

Environmental Impact Assessment is a systematic process used to identify and analyse the likely environmental consequences of a proposed project. It helps decision-makers consider alternatives, design mitigation measures and decide whether or not to approve a project. By assessing impacts in advance, EIA supports more informed and sustainable planning. Thus, its main purpose is to predict and evaluate environmental impacts before key decisions are taken, as stated in Option B.

Option A:
Option A is incorrect because EIA does not aim to rush projects or bypass public consultation. In many jurisdictions, public participation is an integral part of the EIA process.

Option B:
Option B is correct as it highlights the anticipatory nature of EIA. Environmental consequences are examined before major decisions so that they can influence project design and approval.

Option C:
Option C is incorrect because EIA is meant to complement, not replace, economic feasibility studies. Sound planning considers both economic and environmental aspects together.

Option D:
Option D is incorrect since no development project can have absolutely zero environmental impact. EIA seeks to minimise negative impacts and enhance positive ones, not to guarantee total absence of change.

Statements A, B, C, D and F are correct because they distinguish prevention from control, highlight low-carbon options, show cost and impact benefits and recognise the interplay of technology, policy and behaviour. Statement E is false since green technologies can also create new jobs and transform employment patterns rather than always reducing opportunities. Thus, the combination that includes all the correct statements and excludes E is correct.

Option A:
Option A is correct as it offers a balanced view of cleaner technologies, showing both technical strategies and socio-economic interactions, while rejecting simplistic claims about inevitable job losses.

Option B:
Option B is incorrect because it omits F and therefore ignores how policies and user behaviour influence the actual environmental performance of technologies.

Option C:
Option C is incorrect as it includes E, which assumes employment always declines with cleaner technologies, contrary to evidence from many green sectors.

Option D:
Option D is incorrect since it leaves out B, so it fails to distinguish end-of-pipe controls from cleaner production, even though that distinction is important in this unit.

Anupalabdhi is recognised by Bhatta Mimamsa as an independent pramana responsible for cognitions of non-existence or absence. It explains how we know that something is not present when appropriate conditions for its perception are in place but it is nevertheless not experienced. This non-perception is treated as a positive indicator of absence rather than as a mere lack of perception. Hence the pramana described in the stem is anupalabdhi.

Option A:
Option A, sabda, provides knowledge via verbal testimony and does not by itself address how we directly know that something is absent from a given locus. Relying only on testimony would not explain the immediacy of many absence cognitions.

Option B:
Option B, smriti, is memory and relies on past impressions; it cannot explain fresh awareness that an object is currently not present at a particular place.

Option C:
Option C is correct because anupalabdhi is specifically formulated to ground negative knowledge, such as knowing that a book is not on the table when one looks and fails to see it under normal conditions. By positing this pramana, Mimamsa can systematically handle negative existential judgments.

Option D:
Option D, laukika pratyaksha, pertains to ordinary perception of positive entities and cannot alone account for direct awareness of their absence, which is conceptually different.

Norm-referenced assessment interprets an individual’s score relative to the distribution of scores in a defined group. It answers questions such as whether a student scored above or below average compared to peers. The stem clearly mentions comparison with other students,which is characteristic of norm-referenced approaches.

Option A:
Criterion-referenced assessment judges performance against fixed learning standards or objectives,rather than against other students’ scores.

Option B:
Diagnostic assessment is used to identify specific learning difficulties and their causes,not primarily to compare one learner’s performance with others.

Option C:
Norm-referenced interpretation is common in competitive exams where ranks and percentiles are reported,matching the comparison described in the stem.

Option D:
Ipsative assessment compares a learner’s current performance with their own past performance,not with that of others,so it is not appropriate here.

Kevalanvayi inference relies on a vyapti that is confirmed entirely through cases where both hetu and sadhya are present together, with no example of hetu existing without sadhya. The universality of the relation appears from the absence of counter-instances. This pattern is especially clear in cases where the hetu is coextensive with the broader class of the sadhya. Thus the inference in the stem is kevalanvayi.

Option A:
Option A, kevalavyatireki, is based solely on negative instances where both hetu and sadhya are absent together, and has no positive sapaksha examples, making it the opposite configuration.

Option B:
Option B, anvayavyatireki, uses both positive and negative instances and therefore does not restrict itself to only positive evidence.

Option C:
Option C is correct because kevalanvayi literally means "only by affirmative concomitance" and corresponds exactly to the case where there is no locus of hetu without sadhya. It highlights a particularly strong pattern of pervasion.

Option D:
Option D, samanyatodrsta, is a temporal and relational classification dealing with general uniformities rather than the specific structure of evidence for vyapti.

Catuṣkoṭi, or tetralemma, lays out four exhaustive possibilities regarding a statement: affirmation, denial, both and neither. Madhyamaka thinkers like Nāgārjuna use this structure to probe and deconstruct philosophical positions. By showing the difficulties that arise for each alternative, they reveal the emptiness of fixed views. The tetralemma thus functions as a powerful dialectical tool in Buddhist logic.

Option A:
Option A correctly lists the four logical options that define the catuṣkoṭi scheme.

Option B:
Option B reformulates the pattern in terms of scriptural and rational authority, which does not match the classical logical structure.

Option C:
Option C restricts the options to modes of cognition, whereas catuṣkoṭi is framed for general propositions.

Option D:
Option D uses permanence as a specific content area; catuṣkoṭi can be applied to such topics but is not defined by that single contrast.

Statements A, B and D correctly express principles of writing instructional objectives. A is true because action verbs such as “explain”, “classify” or “solve” describe observable behaviours. B is true as conditions (for example, “given a graph…”) clarify the context of performance. D is true because replacing vague verbs with specific ones makes objectives clearer and more assessable. C is wrong since specifying performance criteria helps teachers and learners know what level is expected, and E is wrong because overly broad, non-measurable objectives cannot effectively guide teaching or assessment. Thus C and E only are the wrong statements and form the correct answer.

Option A:
Option A picks C only and overlooks E, even though E also misguides objective writing by favouring unmeasurable statements. Since both C and E are incorrect, C only is not a complete answer.

Option B:
Option B selects E only and ignores C, which downplays the importance of performance standards in objectives. Because two statements are wrong, E only cannot be accepted.

Option C:
Option C groups B, C and E as wrong, but B is actually a correct guideline about including conditions in objectives. Including a true statement among wrong ones makes this option invalid.

Option D:
Option D correctly identifies C and E as the statements that conflict with established principles of behavioural objective writing. It keeps A, B and D separate as accurate statements, so C and E only is the correct option.

Option E adds A to the wrong set, even though A clearly describes a key feature of well-written objectives. Misclassifying A makes A, C and E only unacceptable.

The hexadecimal system has base 16, and 16 equals 2⁴. This means each hex digit corresponds exactly to a group of four bits. This makes hexadecimal a convenient shorthand for binary because each nibble maps to one hex digit.

Option A:
Option A correctly uses the identity 16 = 2⁴ to justify the four-bit groupings. It explains why 4-bit nibbles are natural units when representing binary values in hexadecimal form.

Option B:
Option B, 3, is associated with the octal system, where 8 = 2³ and each digit maps to three bits. It does not apply to base 16.

Option C:
Option C, 2, would yield only four combinations, insufficient to represent 16 different hex symbols (0–9 and A–F).

Option D:
Option D, 8, overestimates the bits per hex digit and would allow 256 combinations, which is far beyond the 16 needed.
