UGC NET Questions (Paper – 1)

Statements D and E are wrong, while A, B, C and F are correct. A and B correctly describe the truth conditions for conjunction and inclusive disjunction, and C accurately symbolises the exclusive “either–or”. F is true because truth tables are standard tools for checking validity. D mistakenly describes a tautology instead of a contradiction, and E wrongly describes the condition for a contingent statement rather than a tautology, so these two are the wrong statements.

Option A:
Option A is incorrect because it singles out only D as wrong and ignores E, which also misrepresents the definition of a tautology. Since both D and E give inverted definitions, treating only one of them as wrong undercounts the errors. Therefore this option does not match the full set of wrong statements.

Option B:
Option B is also incomplete, as it selects only E and ignores D. D is clearly false because a contradiction is never true in any assignment, not always true. By failing to include D, this option again fails to capture all wrong statements listed.

Option C:
Option C is correct because it groups exactly D and E, the two statements that invert the standard meanings of contradiction and tautology. It leaves A, B, C and F untouched, all of which correctly describe truth-functional connectives and the use of truth tables. This combination therefore matches the required set of wrong statements.

Option D:
Option D is wrong because it adds B, which is a correct description of inclusive disjunction, to the set of wrong statements. B rightly states that “p or q” is false only when both p and q are false. Including B beside the genuinely wrong D and E makes the option logically inconsistent.

Climate adaptation focuses on modifying systems and behaviours to cope with the effects of climate change. Examples include building flood defences,changing crop varieties and improving health systems. The stem clearly describes adjustment to impacts,so adaptation is the correct term.

Option A:
Mitigation involves actions to reduce greenhouse gas emissions or enhance sinks and addresses the causes rather than the consequences of climate change. While complementary,it is conceptually distinct from the impact focused measures in the question.

Option B:
Adaptation aims to reduce vulnerability and increase resilience of societies and ecosystems. It may also enable them to benefit from new opportunities such as longer growing seasons in some regions. This emphasis on adjustment matches the stem.

Option C:
Compensation would involve payments or assistance for losses and damages due to climate change. It is a debated issue in climate negotiations but is not the term for proactive adjustment measures.

Option D:
Geoengineering refers to deliberate large scale interventions in the climate system, such as solar radiation management. It goes far beyond local or sectoral adjustments and does not fit the description in the question.

The major challenges for Indian higher education include balancing expansion with quality, promoting equity and inclusion, and addressing the implications of privatization. Statement A is correct because rapid expansion often strains quality assurance mechanisms. Statement B is correct since access for disadvantaged and marginalised groups is still uneven. Statement D is also correct, as privatization can increase costs and raise concerns about social justice and equity. Statement C is wrong because the use of ICT has improved access for many but has certainly not removed all regional disparities, given the persistent digital divide. Thus, the correct combination is A, B and D only.

Option A:
Option A is incorrect because it recognises only A and B as correct and omits D, which accurately highlights the equity and affordability implications of privatization. Excluding D means the option does not reflect the full set of key challenges.

Option B:
Option B is incorrect because it includes only B and D and leaves out A. Quality concerns linked to rapid expansion are a central issue in Indian higher education, so ignoring A makes the combination incomplete.

Option C:
Option C is incorrect because it includes statement C, which wrongly suggests that ICT has removed all regional disparities. While A and D are correct, pairing them with C introduces a false claim, making the option invalid.

Option D:
Option D is correct because it includes precisely those statements that capture the quality, equity and social justice challenges in the current landscape. It excludes C, which overstates the impact of ICT, and thereby presents a balanced and accurate combination of correct statements.

The 3R hierarchy gives priority to options that prevent or minimise waste at source. "Reduce" comes first, as using less material and energy avoids waste altogether. "Reuse" comes next, because using an item again extends its life before it becomes waste. "Recycle" is still useful but comes last among the three because it requires collection and processing. Hence, the preferred order is Reduce → Reuse → Recycle.

Option A:
Option A is incorrect because starting with recycle ignores the greater benefit of reducing consumption. Recycling helps, but it does not avoid production in the first place.

Option B:
Option B is correct as it lists reduction, then reuse, then recycling. This sequence is promoted in policy and education for waste minimisation.

Option C:
Option C is incorrect; putting reuse first still overlooks the importance of avoiding unnecessary items. Prevention is better than reuse.

Option D:
Option D is incorrect because it begins with recycle again. While both reduce and reuse appear, the order does not reflect the standard 3R hierarchy.

A, B and D are correct because they show how knowledge of learners informs planning. A is true as understanding prior knowledge prevents repetition or gaps and helps set an appropriate entry level. B is true since socio-cultural background affects examples, metaphors and language that will be meaningful for students. D is true because knowing learners’ aspirations and goals helps in selecting strategies and tasks that are relevant and motivating. C is false because ability and pace differences are central to planning differentiation, and E is false because learner information is crucial throughout planning, teaching and evaluation; hence A, B and D only is the correct combination.

Option A:
Option A includes A and B but leaves out D, even though learners’ goals and aspirations significantly influence the design of tasks and activities. Omitting D means that an important dimension of learner characteristics is not considered, making this option incomplete.

Option B:
Option B correctly combines A, B and D, covering prior knowledge, socio-cultural context and learner aspirations as key planning inputs. It properly excludes C and E, which wrongly claim that individual differences and ongoing knowledge of learners are unimportant. Therefore A, B and D only is the correct answer.

Option C:
Option C groups B, D and E and treats E as though knowledge of learners is needed only at evaluation. Because E ignores the importance of learner data during planning and teaching, this option mixes true and false statements and cannot be accepted.

Option D:
Option D contains A, C and D, but C suggests that individual differences do not matter in planning, which contradicts learner-centred pedagogy. Including C as a correct statement makes this combination logically unsound.

Option E brings together A, B, D and E but again accepts E, which wrongly limits the use of learner information to evaluation. Since this denies the role of learner data in planning and instruction, A, B, D and E only cannot be considered correct.

PARAKH is intended to guide and improve assessment practices in school education. It will set standards for exams and learning outcomes and organise national achievement surveys to monitor learning, helping states and boards align assessments with competency-based education.

Option A:
Criminal investigations into malpractice are the responsibility of law-enforcement agencies and are not the core function of a national assessment centre like PARAKH.

Option B:
This option correctly reflects PARAKH’s role in standard-setting for assessment and in conducting large-scale learning achievement surveys across the country.

Option C:
University entrance examinations are largely the domain of NTA and other higher education bodies, not PARAKH.

Option D:
Constructing physical infrastructure such as classrooms and hostels is handled through separate schemes and departments, not by an assessment body.

A, B, D and E are sound strategies; C is wrong because assuming something that contradicts given conditions makes the reasoning invalid and can only mislead. Therefore C alone is the wrong statement.

Option A:
Option A is correct because it singles out only C as incorrect and keeps the standard strategies intact.

Option B:
Option B is incorrect because it wrongly treats A as wrong; A is a standard elimination method.

Option C:
Option C is incorrect because it wrongly includes D as wrong; eliminating impossible options does improve chances in MCQs.

Option D:
Option D is incorrect because it wrongly treats B as wrong; combining clues is essential in such puzzles.

NEP 2020 supports calibrated internationalisation by facilitating top global universities to establish campuses in India under regulation and by encouraging Indian HEIs to build international collaborations and exchanges.

Option A:
Option A is incorrect because the policy promotes carefully regulated foreign collaborations rather than prohibiting them.

Option B:
Option B is correct as it summarises the twin strategy of inviting reputed foreign universities and encouraging Indian HEIs to engage in global partnerships and mobility.

Option C:
Option C is wrong since NEP does not force Indian students to study abroad; instead, it aims to make India an attractive global study destination.

Option D:
Option D is incorrect because replacing Indian languages with foreign languages goes against NEP’s strong support for multilingualism and cultural rootedness.

The post hoc fallacy is summarised by the phrase “after this, therefore because of this”. It mistakenly infers a causal relation merely from temporal succession. Just because one event comes after another does not mean the first caused the second. Hence the fallacy described in the stem is correctly called post hoc.

Option A:
Option A, straw man, involves misrepresenting an opponent’s position to make it easier to attack. It does not concern temporal order or causal assumptions. Therefore straw man is not the fallacy being described.

Option B:
Option B, ad hominem, attacks the character of a person instead of addressing the argument. This is a different kind of informal fallacy unrelated to event sequence. Thus ad hominem is not appropriate here.

Option C:
Option C correctly names the post hoc fallacy, which draws a causal conclusion solely from the fact that one event follows another. It warns against confusing correlation with causation. Therefore post hoc is the best answer.

Option D:
Option D, false analogy, bases a conclusion on an inappropriate or weak comparison between cases. While it is an informal fallacy, it does not rely on temporal succession. Hence false analogy cannot be the correct choice.

Bandwidth in networking is commonly used to denote the capacity of a communication link to carry data per unit time. It is usually measured in bits per second or its multiples such as Mbps and Gbps. Higher bandwidth allows more information to flow through the channel simultaneously, improving performance. Thus the description of maximum data transfer rate corresponds to bandwidth.

Option A:
Option A, latency, refers to the delay between sending and receiving data, not the volume that can be transmitted per second. A link may have low latency but limited capacity or vice versa. Therefore latency does not express the maximum rate mentioned in the stem.

Option B:
Option B is correct because bandwidth directly quantifies how much data can move through a network connection in a given period. Service providers often advertise their plans using bandwidth figures, highlighting the throughput users can expect. This aligns exactly with the notion of maximum transmission rate stated in the question.

Option C:
Option C, modulation index, is a parameter in analog and digital modulation techniques describing how a carrier is varied by the signal. It does not by itself indicate how many bits per second can be sent over a channel.

Option D:
Option D, attenuation, means the gradual loss of signal strength as it travels through a medium. While it affects quality, it is not a direct measure of data rate capacity.

Statements A, B and D correctly summarise core features of ODL and online degrees. A is true because distance modes are designed for learners who cannot attend regular campus-based classes. B is true since online offerings rely on video lectures, discussion forums and digital assessments, both live and self-paced. D is also true as regulatory bodies prescribe norms and approval processes for such programmes. Statement C is false; learner support remains essential through study centres, online help and academic counselling. Thus, A, B and D only form the correct combination.

Option A:
Option A is incorrect because it includes only A and B and omits D. Leaving out D fails to acknowledge the regulatory framework that governs the recognition and quality assurance of ODL and online programmes.

Option B:
Option B is correct because it collects all three true statements—about flexible delivery, digital tools and regulatory guidelines—while excluding C, which wrongly suggests that learner support is unnecessary.

Option C:
Option C is incorrect because it combines B and D and omits A, thereby ignoring the defining characteristic of ODL that learners need not attend regular on-campus classes.

Option D:
Option D is incorrect because it treats every statement as correct, including C, which incorrectly denies the importance of structured learner support in non-traditional modes.

Upanaya explicitly connects the general vyapti illustrated in the drstanta with the paksha by stating that the reason found in the example is also present in the subject. It bridges universal and particular, preparing for the conclusion. This application confirms that the paksha falls under the general rule. Therefore the step described in the stem is called upanaya.

Option A:
Option A, nigamana, is the concluding step that restates the thesis as established and comes after the application has been made. It does not itself perform the application.

Option B:
Option B, drstanta, provides the example and statement of vyapti but does not yet relate it to the specific paksha. It sets the stage for upanaya.

Option C:
Option C is correct because upanaya literally means “leading towards” and refers to bringing the paksha under the scope of the vyapti. It is the crucial step that shows the rule is relevant to the particular case.

Option D:
Option D, pratijna, is the initial thesis and not the linking step between general rule and subject.

Semantic barriers arise when sender and receiver attach different meanings to words or symbols. Technical jargon that students do not know prevents them from interpreting the teacher’s message correctly. The problem lies in meanings,not in equipment or attitude. Therefore,the barrier is semantic.

Option A:
Semantic barriers often appear when specialised vocabulary is used without explanation. In such cases,students may hear the words but fail to grasp the concepts. This matches the situation described in the stem,making option A correct.

Option B:
Mechanical barriers are caused by technical problems such as faulty microphones or noise,which the stem does not mention.

Option C:
Psychological barriers involve emotional states like fear or prejudice,rather than unfamiliar jargon.

Option D:
Organisational barriers stem from hierarchical structures and rules that distort messages as they travel through an institution,not from language understanding.

To convert an octal number to binary, each octal digit is replaced by its 3-bit binary equivalent. For 745₈, the digit 7 becomes 111₂, 4 becomes 100₂, and 5 becomes 101₂. Concatenating these gives 111100101₂. Therefore, 111100101₂ is the correct binary representation of 745₈.

Option A:
Option A correctly maps 7→111, 4→100, and 5→101, giving 111100101₂. This approach uses the standard direct mapping rule between octal and binary based on 3-bit groups. Thus, this option faithfully represents the value of 745₈ in base 2.

Option B:
Option B, 111010101₂, corresponds to different 3-bit groups in the middle, implying a digit of 2 or 3 somewhere instead of 4. This does not match the correct octal digit-to-binary mapping for 745₈. Hence, B does not represent 745₈ accurately.

Option C:
Option C, 110111101₂, has a different sequence of bits, especially in the leading and central region, and would correspond to another octal value entirely. Since each octal digit must map exactly to a fixed 3-bit pattern, this pattern cannot correspond to 745₈. Therefore, it is incorrect.

Option D:
Option D, 111001101₂, similarly represents a different binary pattern and thus a different octal number. Its middle bits do not match the required mapping for the digit 4 (100₂), so it cannot be the correct conversion. Thus, this option is also incorrect.

Vyapti is the universal relation of pervasion that ensures that the presence of the hetu implies the presence of the sadhya. It is learned through observation of positive and negative cases or through reliable testimony. Without vyapti, the inferential step from sign to probandum would lack justification. Thus the connection described in the stem is called vyapti.

Option A:
Option A, hetu, is the individual sign such as smoke present in the paksha and does not itself denote the general rule that links all smoke with fire.

Option B:
Option B is correct because vyapti captures precisely the idea that the hetu is never found without the sadhya and forms the logical backbone of valid anumana. It is the bridge that allows us to move from observed instances to reliable conclusions.

Option C:
Option C, drstanta, is a concrete example used to illustrate vyapti, like a kitchen where smoke and fire co-occur, but it is distinct from the universal relation itself.

Option D:
Option D, paksha dharma, refers to a property present in the paksha and indicates a specific occurrence rather than an overarching universal connection.
