UGC NET Questions (Paper – 1)

Vyapti expresses the pervasion relation that underwrites inference: the hetu is found only where the sadhya is found. Knowing vyapti allows one to move securely from the presence of the hetu in the paksha to the presence of the sadhya there. It is established through observing positive and negative instances or through reliable testimony. Thus the universal connection described in the stem is called vyapti.

Option A:
Option A, paksha, is the individual subject where the inference is applied and cannot denote a general relation between two properties.

Option B:
Option B, hetu, is the specific reason or sign used in a given inference, such as smoke, not the general concomitance between smoke and fire.

Option C:
Option C, drstanta, is the example that illustrates vyapti in a familiar case like a kitchen. It helps show the relation but is not itself the relation.

Option D:
Option D is correct because vyapti is technically defined as the invariable concomitance of hetu with sadhya. Without vyapti, inference would lack its justificatory basis.

Savikalpa pratyaksha is defined as perceptual cognition that presents an object with qualifiers such as universals, relations and properties. It allows us to say “this is a pot” rather than merely having an undifferentiated awareness. Nyaya takes such determinate cognitions as the basis for ordinary judgments and discourse. Hence the perception described in the stem is savikalpa pratyaksha.

Option A:
Option A, nirvikalpa, denotes the earlier indeterminate phase that lacks explicit classification; it cannot account for recognition of name and class.

Option B:
Option B is correct because savikalpa literally means “with differentiation,” emphasising the structured, concept-laden character of this perception. It includes both the object and its qualifying features.

Option C:
Option C, yogaja, refers to yogic perception said to arise in highly disciplined minds and is not defined primarily by determinacy versus indeterminacy.

Option D:
Option D, samanyalaksana, is a kind of extraordinary perception of universals and does not capture the ordinary determinate perception of individual objects with all their features.

A, B and C correctly describe padārtha and include standard Nyaya–Vaisheshika categories, and E matches common exam patterns. D is false because “buddhi/jñāna” is at least discussed categorically in Indian philosophies (and in Nyaya–Vaisheshika it is treated under the category of quality/guṇa of the self), so it is incorrect to claim cognition is never treated categorically anywhere. Hence A, B, C and E only are correct.

Option A:
Option A is correct because it includes all true statements and excludes D, which is an overgeneralisation.

Option B:
Option B is incomplete because it omits E (exam identification angle).

Option C:
Option C is incorrect because it includes D (false) and omits A (definition of padārtha).

Option D:
Option D is incorrect because it omits B (dravya/guṇa/karma examples) and includes D (false).

To say that p is necessary for q means that q cannot be true unless p is true. This is equivalent to saying that if p is absent, q must also be absent. Formally, this is symbolised as "if not p, then not q". Thus the conditional described in Option B captures the idea of necessity.

Option A:
Option A, "if p,then q", expresses that p is sufficient for q, since whenever p occurs, q follows. While related, sufficiency and necessity are different relations, and this conditional does not directly state that p is required for q.

Option B:
Option B is correct because "if not p,then not q" asserts that the failure of p guarantees the failure of q, which is exactly what a necessary condition demands. It is logically equivalent to the natural-language statement about necessity.

Option C:
Option C, "if q,then not p", says that whenever q is true, p must be false. This is the opposite of a necessity claim (which requires p when q holds) and would make p incompatible with q rather than required for it. Therefore it cannot represent "p is necessary for q".

Option D:
Option D, "if not q,then p", suggests that the absence of q guarantees the presence of p, a relation unrelated to standard necessity formulation. It neither captures necessity nor sufficiency as usually defined and so cannot be correct.

Statements A, B, C, E and F are correct, whereas D is false. Nyaya recognises four main pramāṇas, and Advaita Vedānta typically extends the list to six, adding arthāpatti and anupalabdhi. Cārvāka is famous for its near-exclusive reliance on perception, and Mīmāṃsā highlights arthāpatti as a distinct means of knowledge. F is right that different schools endorse different sets of pramāṇas, but D is wrong because Buddhist schools do not simply duplicate Nyaya’s list. Therefore A, B, C, E and F only is the correct combination.

Option A:
Option A is incomplete because it omits F, failing to emphasise the cross-school variation in pramāṇa theory, which is central for comparative questions. While A, B, C and E are true, leaving out F makes the portrayal less accurate. Thus A, B, C and E only cannot be accepted.

Option B:
Option B is incorrect because it includes D (which is false) and omits E and F (which are true). Therefore it does not match the full set of correct statements A, B, C, E and F.

Option C:
Option C is correct because it explicitly groups A, B, C, E and F, capturing both specific school positions and the general fact of variation. It excludes D, which oversimplifies Buddhist pramāṇa theory. This reflects the nuanced picture expected in UGC NET questions on Indian epistemology.

Option D:
Option D is incorrect as it includes D while omitting A, thereby accepting a false uniformity of Buddhist and Nyaya pramāṇas and ignoring Nyaya’s own list. The combination therefore contradicts well-known doctrinal differences. Hence B, C, D, E and F only cannot be chosen.

Statements A, B, C and E accurately describe the standard use of Venn diagrams in testing categorical syllogisms, while D and F are false. Each circle stands for a term, shading shows emptiness and an “×” marks possible existence. The usual procedure is to diagram the premises first and then see whether the conclusion is already represented. F is wrong because Paper 1 typically uses up to three circles, not four or more, and D reverses the normal order of steps.

Option A:
Option A is incomplete because it omits E, which states the crucial condition for recognising validity from a Venn diagram. Without E, the answer does not say how the diagrams are actually used to test arguments. Therefore A, B and C only is not fully adequate.

Option B:
Option B is wrong since it leaves out B and adds only A, C and E. Without B, the meaning of shading is not explicitly stated, yet this is essential for interpreting the diagrams correctly. The omission means the option does not cover all correct statements.

Option C:
Option C is correct because it brings together the descriptions of symbols (shading and “×”) with the explanation of how premises and conclusions are related in the method. It excludes D and F, which misdescribe the order of representation and the typical number of circles. Hence this combination matches the approach expected in UGC NET.

Option D:
Option D is incorrect as it includes F, incorrectly suggesting that four-term diagrams are standard, and omits A, so the basic representation of each term by a circle is not even mentioned. This mix of error and omission makes B, C, E and F only an unsuitable answer.

Paksha in Indian logic denotes the subject or locus where the hetu, the middle term, is affirmed. It is the specific case about which the inference is being made. Knowing the paksha helps identify where the conclusion is intended to hold. Therefore the term described in the stem is paksha.

Option A:
Option A correctly names paksha as the subject of inference in which the middle term is present. It is the focus of the inferential claim that the sadhya applies there. Hence this option matches the description.

Option B:
Option B, sapaksha, refers to similar instances where both hetu and sadhya are present, used to illustrate the universal relation. These are examples, not the primary subject of inference. Thus sapaksha is not the correct answer.

Option C:
Option C, vipaksha, denotes counter-instances where the sadhya is absent and typically the hetu should also be absent. It serves to test the universality of vyapti rather than naming the subject of inference. Therefore vipaksha is not appropriate here.

Option D:
Option D, sadhya, is the property to be proved in the paksha, such as “fiery” in “the hill is fiery”. It is the predicate to be established, not the subject itself. Hence sadhya cannot be the correct answer.

Inductive reasoning is used when the premises are intended to make the conclusion likely rather than certain. In this kind of argument, even if all the premises are true, the conclusion can still possibly be false. Inductive arguments are evaluated in terms of strength and weakness, not validity. Thus the probabilistic support described in the stem is characteristic of inductive reasoning.

Option A:
Option A, necessary, is not a type of reasoning but a property of conditions or truths that must hold. It does not name a method of drawing conclusions from premises. Therefore it cannot fill the blank appropriately.

Option B:
Option B, deductive, aims at arguments where the truth of the premises guarantees the truth of the conclusion. Deductive reasoning seeks certainty, not mere probability, and so does not match the description in the question.

Option C:
Option C is correct because inductive reasoning allows us to infer generalisations, predictions or explanations that are more or less probable based on observed evidence. Everyday scientific and statistical inferences are typically inductive in this sense.

Option D:
Option D, demonstrative, is often used as a synonym for strictly proved or deductive reasoning, which again clashes with the idea of probabilistic support. It is therefore not the best term here.

Modus ponens is the classic valid form that affirms the antecedent of a conditional. It states that if “if p, then q” is true and p is true, then q must also be true. This structure preserves truth from premises to conclusion. Therefore the argument form described in the stem is called modus ponens.

Option A:
Option A correctly names modus ponens as the rule that moves from “if p then q” and “p” to “q”. It is one of the most frequently used inference forms in deductive reasoning. Hence this option is the correct answer.

Option B:
Option B, modus tollens, involves denying the consequent by arguing from “if p then q” and “not q” to “not p”. This is a different but also valid pattern. Thus modus tollens does not match the form given here.

Option C:
Option C, disjunctive syllogism, reasons from a disjunction and the denial of one disjunct to the affirmation of the other. It uses “either…or” rather than a conditional premise. Therefore it is not the pattern described in the stem.

Option D:
Option D, hypothetical fallacy, is not a standard name for any recognised valid form. It vaguely suggests an error rather than a rule of inference. Consequently hypothetical fallacy is not an acceptable answer.

Statements A, B, C, D and F correctly describe several informal fallacies and their importance for critical thinking, whereas E is false. These errors arise from ambiguous language or unwarranted moves between parts and wholes, not from the pure symbolic form of arguments. Because they are rooted in content and expression, they are categorised as informal, and identifying them is crucial in analysing exam passages. E incorrectly labels them as formal fallacies. Thus A, B, C, D and F only is the correct combination.

Option A:
Option A is incomplete since it omits F, ignoring the explicit statement about their use in evaluating UGC NET passages. Without F, the option lacks the exam connection. Therefore A, B, C and D only is not entirely adequate.

Option B:
Option B is wrong because it adds E, treating these language-based fallacies as formal, which conflicts with the usual classification in logic textbooks. Formal fallacies arise from invalid structure, not from ambiguous wording or content. Including E therefore makes the option incorrect.

Option C:
Option C is correct because it collects the accurate definitions and classifications of these fallacies together with their role in critical reasoning tasks. It explicitly rejects the misclassification in E. This matches how these topics are presented in Paper 1 preparation.

Option D:
Option D is incorrect since it includes E and omits A, losing the definition of equivocation while endorsing the wrong type-label. This combination does not align with the standard logical treatment of fallacies.

Statements A, B, C, D and F correctly explain how vyāpti is supported in Indian logic, while E is false. Nyaya stresses repeated observation without exception, looking at agreement in presence (anvaya) and agreement in absence (vyatireka). Tarka helps eliminate competing hypotheses, strengthening confidence in the concomitance. If a genuine counterexample appears, the vyāpti must be revised, so E is incorrect. UGC NET often uses the smoke–fire example to test recognition of these methods. Hence A, B, C, D and F only is the correct combination.

Option A:
Option A is incomplete because it omits F, missing the explicit note that such methods appear in exam questions. Although A, B, C and D are conceptually sound, they do not link back to UGC NET practice. Therefore this option is not fully adequate.

Option B:
Option B is wrong since it omits A and includes only B, C, D and F, failing to mention the central requirement of repeated observation and absence of counterexamples. Without A, the empirical grounding of vyāpti is underplayed. This omission makes the option incomplete.

Option C:
Option C is incorrect as it includes E, which claims that vyāpti is irrevocable once established. The very idea of counterexamples shows that generalisations can and should be revised when new evidence arises. Including E therefore undermines the logic of empirical inference.

Option D:
Option D is correct because it unites the descriptive and methodological points about anvaya, vyatireka and tarka with the exam style of questioning, while rejecting the rigid, unscientific claim in E. It reflects both traditional theory and its modern pedagogical use.

Pratijna is the first member of the Nyaya inference that clearly states what is to be proved. It combines the paksha and sadhya into a single assertion, guiding the listener to the intended conclusion. Subsequent steps supply reasons and examples to support this thesis. Hence the initial statement described in the stem is called pratijna.

Option A:
Option A, upanaya, is the fourth step that applies the general rule to the paksha and therefore cannot be the opening thesis.

Option B:
Option B is correct because pratijna explicitly names the declarative starting point of the argument. Without stating the pratijna, the inferential chain would lack direction and purpose.

Option C:
Option C, nigamana, is the final step where the thesis is restated as established, not the initial proposal.

Option D:
Option D, hetu, is the reason given in favour of the pratijna, usually introduced as the second member of the inference.

Upanaya explicitly connects the general vyapti exemplified in the drstanta with the paksha by affirming that the hetu occurs in the subject in the same way as in the example. This shows that the subject falls under the scope of the universal rule. It prepares the ground for the final conclusion that the sadhya is present in the paksha. Hence the step described in the stem is called upanaya.

Option A:
Option A, udaharana, states the general rule along with the illustrative example but does not yet link that rule to the specific paksha. It functions earlier in the sequence to establish vyapti.

Option B:
Option B, nigamana, is the final conclusion that restates the thesis as established after upanaya has been made. It is the outcome rather than the application step.

Option C:
Option C is correct because upanaya literally means "leading towards" and signifies bringing the paksha under the general relation, which is exactly what the stem describes.

Option D:
Option D, pratijna, introduces the thesis at the beginning of the argument and does not perform the explicit application of the rule to the subject.

Statements A, B, C and E correctly describe how quantifiers are treated in logic and in the exam, while D is false. Logical “some” is inclusive and allows the possibility that all elements satisfy the predicate, even if conversational usage often suggests otherwise. The universal “all” and “no” correspond to familiar A and E categorical forms, and careful attention to these meanings is essential for solving UGC NET syllogism questions. Thus the combination that includes all true statements and excludes D is A, B, C, E only.

Option A:
Option A is correct because it gathers the logically accurate descriptions of “all”, “some” and “no” and emphasises exam importance, while omitting the misleading claim in D. It reflects both formal semantics and practical test-taking needs.

Option B:
Option B is incomplete since it leaves out E, failing to mention the explicit role quantifiers play in UGC NET question interpretation. A, B, C only therefore does not fully answer the question.

Option C:
Option C is wrong because it omits A, dropping the clear linkage between “all” and universal statements, and so B, C, E only presents only part of the correct picture. Missing A is significant because universal claims are central to categorical logic.

Option D:
Option D is also incorrect as it excludes B, leaving out the crucial clarification that logical “some” does not automatically imply “not all”. A, C, E only is therefore not the full set of true statements.

Purvavat anumana moves from knowledge of a cause to knowledge of an effect that has not yet manifested. Observing dark, moisture-laden clouds and concluding that it will rain is a classic example. The temporal sequence runs from earlier cause to later effect, which is why this type is called purvavat. Nyaya recognises it as one important pattern of causal inference.

Option A:
Option A, sesavat, reverses the direction by inferring a prior cause from a present effect and thus does not fit the forward-looking pattern described in the stem.

Option B:
Option B, samanyatodrsta, involves inference from general concomitance that is not necessarily causal and therefore is too broad and differently structured.

Option C:
Option C, anvayavyatireki, classifies inference by the way vyapti is established through positive and negative instances, not by the temporal relation between cause and effect.

Option D:
Option D is correct because purvavat literally means "based on the prior" and specifically captures the move from earlier causal conditions to later outcomes.
