UGC NET Questions (Paper – 1)

Statements A and B give the standard truth conditions for conjunction and inclusive disjunction. Statement D is correct because p → q is equivalent to ¬p ∨ q in classical logic. Statement E is also true since connectives allow us to build complex propositions from atomic ones. Statement C is false because ¬p is true when p is false, not when p is true. Thus A, B, D and E only form the correct set.

Option A:
Option A is incomplete as it omits E and therefore does not mention the important role of connectives in constructing compound statements, even though A, B and D are true.

Option B:
Option B is correct since it includes all true statements and excludes C, which reverses the meaning of negation. It matches the truth-table definitions that NET candidates must know.

Option C:
Option C is incorrect because it contains C, the wrong description of negation, despite including some true statements, so the overall set cannot be accepted.

Option D:
Option D is also wrong as it retains C and omits A, losing the clear definition of conjunction while endorsing an incorrect statement about negation.

Teaching aptitude refers to a combination of interests,attitudes and abilities that predispose an individual to be successful and satisfied in the teaching profession. Enjoying interaction with learners and staying committed to teaching responsibilities are strong indicators of such aptitude. People with high teaching aptitude are more likely to invest effort in professional growth. Therefore,the trait described in the stem is best labelled teaching aptitude.

Option A:
Administrative power is related to authority and decision-making positions in an institution but does not necessarily reflect enjoyment of teaching activities or close work with students.

Option B:
Teaching aptitude underlies the choice of teaching as a career and resilience in facing classroom challenges. Because the stem highlights a stable tendency to enjoy and remain committed to teaching tasks,this option accurately captures the construct.

Option C:
Economic status concerns income or wealth levels and may influence career choice but is not itself a psychological tendency related to enjoyment of teaching.

Option D:
Physical strength may be useful in some tasks but is not a primary indicator of suitability for the intellectual and emotional demands of teaching.

Defensiveness is a psychological state in which individuals feel threatened and protect their self image by resisting messages. The student in the stem misreads constructive feedback as hostile and withdraws attention. This blocking of listening is a sign of defensiveness.

Option A:
Redundancy refers to repetition of message elements and does not involve emotional self protection.

Option B:
Empathy is about understanding others' feelings,which is opposite to defensive closure.

Option C:
The description clearly fits defensiveness,making this option correct.

Option D:
Mechanical failure relates to equipment breakdown,not human reactions.

NEP 2020 proposes that NCTE develop National Professional Standards for Teachers (NPST) that clearly articulate the knowledge, skills, values and responsibilities expected of teachers at different career stages and guide recruitment, appraisal and professional development.

Option A:
This option is correct because it captures the idea of NPST as a structured framework of competencies and responsibilities.

Option B:
A list of punishments is not a standards framework; NEP focuses on constructive support and development rather than fear-based control.

Option C:
Reducing teacher quality to a single exam ignores the complex, ongoing nature of teaching competence that the policy recognises.

Option D:
Treating standards as optional suggestions would defeat their purpose of guiding policy and institutional practice.

Statements A, C and E are correct because effective teaching generally proceeds from simple to complex ideas, links new content with prior experience and offers practice and reinforcement. B is false since ignoring learner errors prevents timely remediation and can widen learning gaps. D is false because effective teaching is responsive and adapts to feedback rather than rigidly following a fixed sequence. Therefore, A, C and E only forms the correct combination.

Option A:
Option A accurately combines A, C and E, all of which reflect widely accepted principles of sequencing, relating to prior experience and providing practice. It excludes B and D, which disregard learner difficulties and feedback, so this option is correct.

Option B:
Option B adds D to A and C, but D wrongly suggests that teaching must never respond to classroom feedback. Including D contradicts the idea of adaptive teaching, making A, C and D only an invalid set.

Option C:
Option C groups B, C, D and E but includes B and D, both of which promote ignoring learner difficulties and feedback. Even though C and E are true, the presence of two false statements invalidates the option.

Option D:
Option D lists A, B, C and E and retains B, which advocates ignoring errors, so it mixes correct and incorrect ideas about effective teaching. As a result, A, B, C and E only cannot be accepted as correct.

Intergenerational equity focuses on fairness between present and future generations. It demands that today’s development choices do not degrade environmental or resource bases to the extent that future people are disadvantaged. The stem clearly refers to rights and opportunities of future generations,so intergenerational is the accurate term.

Option A:
Intragenerational equity concerns fairness within the same generation,for example between rich and poor people living today. While important,it does not address the time dimension highlighted in the question.

Option B:
Intergenerational equity is central to sustainable development discourse and is reflected in the Brundtland definition. It insists that each generation acts as a steward of the planet for those yet unborn. This understanding matches the description in the stem.

Option C:
Horizontal and vertical equity are general terms used in public finance and health policy to describe fairness among similar or differently situated individuals within the same generation. They do not inherently involve future generations,so they are not suitable completions.

Option D:
Vertical equity usually refers to treating people with different abilities to pay differently in tax systems,which is unrelated to environmental obligations to future people. Therefore it cannot be correct here.

Statements A, B, C and E correctly describe how computers and specialised software support research. They help with data management, statistical analysis, citation organisation and qualitative coding and visualisation. Statement D is false because the use of software does not eliminate the need to understand statistics; researchers must still select appropriate tests, interpret outputs and recognise limitations. Thus, the combination including A, B, C and E is correct.

Option A:
Option A is incomplete as it omits E, overlooking the important role of qualitative data analysis software in handling textual or multimedia materials. Without E, the option gives a partial picture focused mainly on quantitative and reference tasks.

Option B:
Option B contains B, C and E but leaves out A, failing to note that basic data storage and cleaning are fundamental computer-assisted tasks in research. This omission makes the description of computer use incomplete.

Option C:
Option C includes A, C and E but omits B, thereby ignoring the central role of statistical software packages, which are key tools in empirical research. As such, this option does not cover the full range of computer applications.

Option D:
Option D is correct because it groups all the true statements together and excludes D, which wrongly suggests that conceptual understanding of statistics is unnecessary. It recognises computers as powerful aids, not substitutes for methodological competence.

Mobile learning, often abbreviated as m-learning, emphasises the use of portable devices for flexible access to learning materials and interactions. It supports learning on the move, enabling students to engage with content during transit or outside formal settings. Features like apps, notifications and offline content enhance its effectiveness. Hence, the mode described in the stem is mobile learning.

Option A:
Option A, micro, could refer to short learning units but does not inherently involve mobile devices, so it is not the best descriptor here.

Option B:
Option B is correct because the defining characteristic in the question is the use of smartphones and tablets for anywhere, anytime access, which is central to mobile learning.

Option C:
Option C, managed, lacks specific meaning in this context and could relate to administrative processes rather than delivery through devices.

Option D:
Option D, masked, is unrelated to educational modes and does not capture the role of ICT.

Asiddha hetu fails because the alleged reason does not exist or is not known to exist in the paksha. Since the foundational fact is missing, no valid inference can proceed from it. Nyaya lists several subtypes depending on why the hetu is unestablished. Thus the defective reason described in the stem is asiddha.

Option A:
Option A, viruddha, focuses on reasons that prove the opposite conclusion, not on absence of the reason in the subject.

Option B:
Option B is correct because asiddha literally means “unaccomplished” or “unproved” and captures the idea that the reason has not been successfully shown in the very locus where it is needed.

Option C:
Option C, badhita, involves reasons whose supposed vyapti is contradicted by stronger evidence, even if they are present in the paksha.

Option D:
Option D, nirvikalpa, describes a kind of indeterminate perception and is not a classification of hetu at all.

This option is correct because the basic formula for uniform motion is distance = speed × time. Speed tells how much distance is covered per unit time. Multiplying it by the time gives the total distance travelled. Therefore, distance equals speed multiplied by time.

Option A:
Speed is defined as distance per unit time. When we multiply this rate by the actual time travelled, the time units cancel appropriately, leaving total distance. This matches the formula for uniform motion and makes this option correct.

Option B:
Acceleration measures how quickly speed changes over time, not directly how far an object travels. It does not multiply with time to give distance in the simple uniform motion formula. Hence, this option is not correct here.

Option C:
Momentum is the product of mass and velocity and belongs to mechanics, not basic kinematics equations of distance. It does not appear in the elementary distance-speed-time relation. Therefore, momentum is irrelevant to the question.

Option D:
Power measures the rate at which work is done or energy is transferred. It is not used to compute distance in uniform motion problems. Thus, this option does not fit the relationship described.

Statements A, B, C and E correctly describe śabda as Nyaya’s pramāṇa of testimony and its dependence on a trustworthy speaker, with scripture as a special case. D is false because Nyaya allows reliable secular testimony too. Hence A, B, C and E only is correct.

Option A:
Option A is incomplete because it omits E (exam classification point).

Option B:
Option B is incorrect because it includes D (false restriction to Veda only).

Option C:
Option C is incorrect because it omits A (āpta-vākya definition), so it is incomplete.

Option D:
Option D is correct because it includes all true statements and excludes D.

Statements A, B, D and E correctly characterise asiddha hetu as a middle term that is not properly established, either because it does not qualify the pakṣa or is itself impossible, and note its place in UGC NET questions. C is false because a hetu present in the pakṣa but absent in all sapakṣa cases is rather an example of asādhāraṇa or improperly restricted reason, not simply asiddha. Thus the true statements are A, B, D and E only.

Option A:
Option A is correct since it includes all the accurate descriptions and the exam-related remark, while excluding C which mislabels a different defect as asiddha. It reflects the standard Nyaya classification of hetvābhāsa.

Option B:
Option B is incomplete because it omits E, failing to mention that UGC NET often provides examples of such fallacious reasons in the options. Without E, the exam application of the concept is missing.

Option C:
Option C is incorrect as it drops A, losing the basic idea that asiddha hetu is unestablished in the pakṣa, and it also keeps an incomplete/incorrect mix. So it does not include all true statements.

Option D:
Option D is wrong because it keeps C (false) and omits B (true), so it cannot be the correct combination.

Statements A, B and C define the three Nyaya types of inference by reference to positive and negative correlations, and D notes that in all cases the notion of vyāpti underlies inference. F is correct because UGC NET may present examples and ask which type they exemplify. E is false since Nyaya explicitly uses anvaya and vyatireka to help support vyāpti. Therefore A, B, C, D and F only is the correct combination.

Option A:
Option A is incomplete as it omits F, failing to mention the examination angle of identifying such inference types.

Option B:
Option B is incorrect because it omits C (anvayavyatireki), so it does not include all true statements.

Option C:
Option C is wrong because it includes E, which denies the role of anvaya/vyatireka in supporting vyāpti.

Option D:
Option D is correct because it includes all true statements and excludes the false one (E).

Statements A, B, C and D all describe logically possible combinations of truth and validity, whereas E is false. Validity concerns whether a true-premise situation can ever lead to a false conclusion; it does not rule out cases where premises are false. Invalid arguments with true premises may happen to have true conclusions, showing that invalidity does not force falsity of the conclusion. Hence the only wrong claim is that every invalid argument with true premises must have a false conclusion, making E the unique incorrect statement.

Option A:
Option A is wrong because it marks D as the sole incorrect statement even though D correctly notes that invalid arguments can still reach true conclusions by coincidence. Treating D as wrong confuses the distinction between logical guarantee and accidental truth.

Option B:
Option B is correct since it singles out E, which overstates the consequences of invalidity, as the only false statement among generally accepted logical possibilities. This fits the standard truth–validity matrix taught for exam preparation.

Option C:
Option C fails because it groups D with E as wrong, but D is a well-known counterexample pattern to the idea that invalidity always yields false conclusions. Saying D and E only misrepresents one true logical observation.

Option D:
Option D is also incorrect, as it labels C as wrong along with D and E, even though C simply describes a possible situation where a valid form is used with false premises and a false conclusion. As long as there is no row with true premises and a false conclusion, such a case is compatible with validity.

Statements A, B, C and E are correct, while D is false. The law of excluded middle asserts that for any proposition p, either p or ¬p holds in classical two-valued logic, with no third option. Some non-classical systems, such as intuitionistic logic, restrict or reject this law in certain contexts, which supports C. In classical logic, “p ∨ ¬p” is a tautology, not a contradiction, so D mislabels it. UGC NET logic questions frequently refer to excluded middle and non-contradiction, as E indicates. Therefore A, B, C, E only is the correct set.

Option A:
Option A is incomplete since it omits E, not mentioning the exam’s interest in these fundamental laws. A, B, C only therefore does not fully satisfy the stem.

Option B:
Option B is wrong because it leaves out C, failing to acknowledge that some non-classical logics challenge the universal scope of excluded middle. A, B, E only thus presents too narrow a view.

Option C:
Option C is incorrect as it omits A and thereby fails to state the law itself, giving only its context and exam relevance. B, C, E only therefore does not directly identify excluded middle.

Option D:
Option D is correct because it collects the accurate statements about the law, its classical role, its non-classical challenges and its exam importance while excluding D, which wrongly calls “p ∨ ¬p” a contradiction. This selection matches standard introductions to logic and UGC NET-level treatments.
