UGC NET Questions (Paper – 1)

Statements A, B, C, D and F provide a sound framework for evaluating causal arguments, whereas E is false. Causal chains may involve remote and intermediate causes, and mixing up mere conditions with true causes can distort explanations. The post hoc fallacy warns against inferring causation from mere temporal sequence, and good arguments should check alternative hypotheses. UGC NET sometimes presents data scenarios where candidates must select the most plausible causal explanation. E is wrong because a single correlation rarely suffices to establish strong causation.

Option A:
Option A is incomplete because it omits F, failing to mention how these ideas are used in UGC NET data and reasoning items. While A, B, C and D are true, they do not reference the exam context, which the question invites by including F. Hence A, B, C and D only is not fully adequate.

Option B:
Option B is correct as it collects all the true statements and excludes E, which conflates correlation with causation. It captures both conceptual standards for evaluating causal arguments and their exam application. Therefore A, B, C, D and F only is the appropriate answer.

Option C:
Option C is wrong because it includes E, which overstates the evidential power of a single correlation, and omits A, thereby leaving out the idea of multi-step causal chains. This mixture of omission and error makes B, C, D, E and F only unsuitable.

Option D:
Option D is incorrect since it includes E and omits B, ignoring the crucial distinction between enabling conditions and genuine causes while accepting an over-strong claim about correlation. Thus A, C, D, E and F only cannot be chosen as correct.

A, B and C correctly explain syādvāda as conditional/standpoint-based predication, and E is true about syllabus linkage with anekāntavāda. D is false because syādvāda qualifies truth-claims; it does not declare all statements meaningless or equally false. Thus A, B, C and E only are correct.

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

Option B:
Option B is incomplete because it omits E (exam association point).

Option C:
Option C is incomplete because it omits A (standpoints/naya are central).

Option D:
Option D is incorrect because it includes D (false).

Statements A, B and C correctly describe mood, figure and the Barbara form, and E is also true, while D and F are false. The three-term rule states that a valid syllogism must have exactly three distinct terms, so a four-term syllogism is invalid. In the second figure, the middle term actually appears as predicate in both premises, not “never as predicate”. Exam items often ask students to classify mood and figure. Thus the correct group of statements is A, B, C and E only.

Option A:
Option A is incomplete because it leaves out E, which notes the exam practice of asking about mood and figure. Although A, B and C describe the technical notions, they do not show how these ideas appear in UGC NET. Therefore this combination is not fully aligned with the question.

Option B:
Option B is correct since it collects the three structural facts and the exam-oriented statement while excluding D and F, which contradict basic rules. It stays faithful to both classical logic and test patterns. This makes it the accurate choice.

Option C:
Option C is wrong because it includes D, incorrectly claiming that a four-term syllogism is valid, and still omits nothing to correct that mistake. Once the number of distinct terms exceeds three, the form cannot be a standard valid syllogism. Hence the option is logically flawed.

Option D:
Option D is incorrect since it uses B, C, E and F only, omitting A and accepting F. Without A, the meaning of mood is missing, and F misdescribes the position of the middle term in the second figure. Therefore this option cannot be the right answer.

Statements A, B, C and E correctly characterise truth-functional connectives and their exam role, while D is false. A connective like “and” or “or” yields compound truth values determined entirely by the truth of their components, and truth tables provide a systematic way to evaluate them. “Because” is generally not treated as a purely truth-functional connective at this level, as it carries causal or explanatory content. Thus A, B, C and E only gives the complete set of correct statements.

Option A:
Option A is incomplete because it drops E, failing to mention the practical utility of this knowledge in UGC NET truth-table questions. A, B, C only therefore does not fully reflect the exam-focused part of the stem.

Option B:
Option B is wrong since it omits A, the general definition of a truth-functional connective, leaving only specific examples and exam commentary. B, C, E only thus lacks the conceptual core that defines what these connectives are.

Option C:
Option C is incorrect because it includes A and C and E but leaves out B, so it does not explicitly state that “and”, “or” and “if…then” are the typical connectives used in UGC NET symbolic logic. A, C, E only is therefore incomplete.

Option D:
Option D is correct as it includes all the true statements and excludes D, which wrongly promotes “because” to the status of a standard truth-functional symbol. This combination matches textbook treatments and exam expectations.

Conjunction is the compound statement formed by connecting two propositions with "and". According to its truth table, a conjunction is true only when each conjunct is true. This aligns with our intuitive understanding that both conditions must be met. Therefore the connective described in the question is correctly termed conjunction.

Option A:
Option A is correct because conjunction specifically denotes the logical operator that joins statements with "and" and demands the truth of all of them. It is one of the fundamental truth-functional connectives in propositional logic. The stem’s description matches this behaviour exactly.

Option B:
Option B, disjunction, connects statements with "or" and is usually interpreted in logic as true if at least one of the disjuncts is true. It does not require both components to be true, so it does not fit the question.

Option C:
Option C, implication, represents a conditional statement of the form "if p, then q". Its truth conditions differ significantly from those of conjunction and do not match the requirement that both parts be true.

Option D:
Option D, negation, operates on a single proposition by reversing its truth value. It does not combine two statements at all and thus cannot be the connective described.

Statements A, B, C, D and E provide a correct overview of ordinary and extraordinary perception, while F is false. Ordinary perception uses the usual senses, whereas alaukika covers more refined or extraordinary modes such as universals, mediated perception and yogic awareness. These are treated as forms of pratyakṣa by schools like Nyaya and some Vedānta traditions. F is wrong because not all schools dismiss such perception as mere illusion; rather, they debate its scope and clarity. Therefore A, B, C, D and E only is the correct combination.

Option A:
Option A is incomplete since it omits E, failing to mention the yogaja form, which is an important part of alaukika perception. While A, B, C and D are true, they do not fully cover the extraordinary types. Thus this option is not fully satisfactory.

Option B:
Option B is correct as it gathers the chief categories and examples of laukika and alaukika perception without adopting the extreme sceptical view expressed in F. It matches the level of detail expected in UGC NET questions. Hence it is the appropriate answer.

Option C:
Option C is wrong because it includes F and omits A, thereby accepting the claim that all schools reject alaukika perception and not stating what laukika perception is. This misrepresents the diversity of Indian epistemological positions. The combination is therefore incorrect.

Option D:
Option D is incorrect since it includes F and omits B, dropping explicit mention of the main extraordinary types while endorsing an overgeneralisation about their rejection. This option does not accurately reflect Indian epistemology.

In UGC NET assertion–reason items, special codes indicate the truth values of A and R and their explanatory relation. When both statements are true and the reason genuinely explains the assertion, a specific code is prescribed. That code explicitly mentions that A and R are true and that R is the correct explanation of A. Hence the code described in the stem corresponds to Option A.

Option A:
Option A accurately states that A is true, R is true and R correctly explains A. This matches the condition specified in the question. Therefore it is the appropriate code for this pattern of truth and explanation.

Option B:
Option B states that both A and R are true but R is not the correct explanation of A. This is used when the statements are independently true but not explanatorily linked. It thus fails to capture the explanatory relation mentioned in the stem.

Option C:
Option C reports that A is true while R is false. Under this code, the reason cannot possibly explain the assertion. Therefore it contradicts the condition that both A and R are true and related explanatorily.

Option D:
Option D indicates that A is false and R is true, which reverses the state of the assertion. In such a case, R cannot correctly explain a false assertion. Hence this code does not satisfy the description in the question.

Anvayavyatireki anumana secures vyapti through a combination of affirmative and negative instances: cases where hetu and sadhya co-occur and cases where both are absent. This dual confirmation provides strong support for the universality of the connection. Nyaya often regards this as the most robust form of inferential support. Hence the inference described in the stem is anvayavyatireki.

Option A:
Option A, kevalanvayi, relies only on positive instances and does not require complementary negative cases.

Option B:
Option B is correct because anvaya refers to concordant presence and vyatireka to concordant absence; together they describe the two-sided evidence mentioned in the stem.

Option C:
Option C, kevalavyatireki, restricts itself to negative instances and so lacks the positive confirmations characteristic of the present pattern.

Option D:
Option D, sesavat, differentiates inference according to an effect-to-cause temporal relation and is not based on how vyapti is established.

Satpratipaksha occurs when a reason offered for a conclusion is matched by another reason of comparable strength offered for its negation. In such a situation, the original hetu loses its probative force because the opposing argument cancels its effect. Nyaya regards this as a defect since the presence of a true counter-argument prevents the conclusion from being firmly established.

Option A:
Option A, badhita, involves defeat by a stronger pramana rather than by a rival but equally strong inferential ground. In badhita, the balance of justification is clearly tipped.

Option B:
Option B, savyabhicara, refers to irregular association and does not require any explicit counter-reason.

Option C:
Option C, asiddha, is concerned with the failure to establish the hetu in the paksha, which is different from the stalemate generated by opposing but symmetric reasons.

Option D:
Option D is correct because satpratipaksha literally means "having a true counter-argument" and indicates that the original reason is undermined by the presence of such balanced opposition.

Statements A, C, D and E correctly summarise Nyaya’s treatment of doubt, while B is false. Nyaya regards doubt as an intermediate, uncertain cognition that prompts inquiry, not as a pramāṇa. Valid knowledge, by contrast, removes doubt and error, and its analysis considers factors like similarity of marks and conflicting indications. Because UGC NET Indian logic questions sometimes ask for definitions and causes of doubt, E is also true. Thus A, C, D, E only forms the correct group.

Option A:
Option A is incomplete as it omits E, not mentioning the exam relevance explicitly emphasised in the stem. A, C, D only therefore does not fully answer the question.

Option B:
Option B is correct because it collects all true statements and excludes B, which wrongly elevates doubt to the status of a knowledge-source. This reflects Nyaya epistemology and its use in UGC NET questions.

Option C:
Option C is wrong since it leaves out A, so C, D, E only does not define doubt as a state of uncertainty between alternatives, giving an incomplete account.

Option D:
Option D is incorrect because it includes B, which mischaracterises doubt as a pramāṇa, and so A, B, C, D only mixes false and true claims.

A tautology is a formula that evaluates to true on every row of its truth table, regardless of how its component propositions are valued. Its truth depends purely on its logical form, not on any contingent facts. Tautologies serve as logical truths that cannot be denied without inconsistency. Thus the compound statement described in the stem is a tautology.

Option A:
Option A, contradiction, is the opposite extreme: a statement that is false under every possible valuation. It cannot ever be true, which does not match the always-true condition in the question. Therefore contradiction is not correct.

Option B:
Option B, contingency, may be true under some valuations and false under others. Its truth is not fixed across all possibilities, so it fails to meet the "true under every" condition. Thus contingency is not appropriate here.

Option C:
Option C, paradox, is an informal term for statements that seem self-contradictory or counterintuitive but may contain a deeper truth. Paradoxes are not defined simply by their truth table behaviour. Consequently paradox does not answer the question.

Option D:
Option D is correct because tautology exactly captures the notion of a statement that cannot come out false on any truth-value assignment. Such statements are central to proofs and equivalence tests in logic.

Statements A, B, C and E correctly capture the differences between argument, explanation and description and their role in exam passages, while D is false. Arguments give reasons for accepting a claim; explanations clarify why an accepted fact holds; descriptions simply present information. The presence of “because” can occur in explanations as well as arguments, so D overgeneralises. Hence the true statements are exactly A, B, C and E.

Option A:
Option A is correct because it collects all and only the true statements, including the exam-oriented point E, while excluding D which misclassifies every “because” passage as argument. It reflects the conceptual distinctions tested in UGC NET. By combining A, B, C and E, it gives a complete and accurate picture of the three discourse types.

Option B:
Option B is incorrect because it omits E, thereby ignoring the explicit exam relevance of distinguishing these categories. Although A, B and C are true, this combination does not include all the correct statements. It therefore under-represents the information given in the stem.

Option C:
Option C is wrong since it includes D, which claims that any “because” passage must be an argument and never an explanation. This is not accurate, as explanatory texts also use “because” without trying to prove a claim. By treating D as correct, this option misleads about the nature of explanations.

Option D:
Option D is incorrect because it leaves out A, failing to mention that arguments characteristically offer reasons for a conclusion. It also keeps E but still does not gather all the true statements together. Hence B, C and E only cannot be the right answer.

The wrong statement is D only. A, B, C, E and F are correct. D is false because a true conclusion can be reached via an invalid (fallacious) argument. F is correct because validity is a matter of logical form (truth-preservation across possible cases), not the actual truth or falsity of the premises in the real world.

Option A:
Option A is correct because it identifies D alone as wrong and correctly treats F as a true description of validity being form-based. This matches standard textbook definitions used in UGC NET reasoning.

Option B:
Option B is incorrect because it marks F as wrong, but F correctly states that validity depends on form, not on the actual truth/falsity of premises. So “F only” cannot be right.

Option C:
Option C is incorrect because it wrongly includes C as a wrong statement, even though C is the standard definition of soundness (valid + true premises). It also includes F, which is correct.

Option D:
Option D is incorrect because it includes F among the wrong statements. Since F is correct, the set “D and F only” is not the right answer.

Samanyatodrsta anumana draws on broadly experienced uniformities that may not fit neatly into a strict cause–effect pattern. For instance, we infer motion whenever we see continuous change of place, based on a general understanding that changing position goes with being in motion. The relation is grounded in common experience rather than in a specific causal law. Hence such inferences are called samanyatodrsta.

Option A:
Option A, purvavat, is restricted to cause-to-effect reasoning and cannot cover all uniformities that are not clearly causal, such as certain spatial or kinematic regularities.

Option B:
Option B is correct because samanyatodrsta literally means "known from generality" and is designed to handle inferences from widely observed associations, not only from recognised causal links.

Option C:
Option C, sesavat, is effect-to-cause inference and therefore does not match the non-causal generality highlighted in the example.

Option D:
Option D, anvayavyatireki, classifies inference by its use of positive and negative instances for vyapti, not by the causal or non-causal nature of the relation.

A, B, C and E are correct; D is false. Nyaya accepts all three types (anvaya-vyatireki, kevalānvayi, kevalavyatireki) as valid classifications of inference, and UGC NET may ask to classify examples.

Option A:
Option A is incomplete because it omits E (classification question pattern), which is true.

Option B:
Option B is incomplete because it omits B (kevalānvayi), which is true and necessary for the full set.

Option C:
Option C is incomplete because it omits A (anvaya-vyatireki), which is true and central.

Option D:
Option D is correct because it includes all true statements (A, B, C, E) and excludes D (false).
