UGC NET Questions (Paper – 1)

Nirvikalpa pratyaksha is described as an indeterminate awareness that grasps an object in a bare, non-relational way. At this stage, the mind has not yet organised the content into subject–predicate form or recognised it under a concept. Nyaya treats this as an initial phase preceding determinate judgment. Hence the perception referred to in the stem is nirvikalpa pratyaksha.

Option A:
Option A is correct because nirvikalpa literally means "without differentiation", highlighting the lack of explicit classification, naming or relational articulation in this cognition. It is important for explaining how determinate perception can have a non-conceptual base.

Option B:
Option B, savikalpa, is determinate perception that includes recognition of universals and relations, which contradicts the description of being without name or class. It belongs to a later stage of perceptual processing.

Option C:
Option C, laukika, denotes ordinary empirical perception and cuts across the distinction between determinate and indeterminate; laukika perception can itself be either nirvikalpa or savikalpa.

Option D:
Option D, alaukika, refers to extraordinary perception and again is a classification orthogonal to the determinate–indeterminate division, so it does not answer the specific description in the stem.

A, B, C and E are correct. D is false because natural language uses of “if/only if” can be looser than strict logical operators. Therefore the correct combination is A, B, C and E only.

Option A:
Option A is incomplete because it omits E (exam translation importance).

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

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

Option D:
Option D is incorrect because it omits A, so it is incomplete.

A valid argument is one whose logical form guarantees that if the premises are true, the conclusion must also be true. This condition rules out any counterexample with true premises and a false conclusion. Validity concerns the structure of the argument rather than the actual truth of its premises. Therefore the type of argument described in the stem is a valid argument.

Option A:
Option A is correct because validity is defined precisely by the impossibility of true premises leading to a false conclusion. Even if the premises are in fact false, a valid form ensures that no logically consistent counterexample violates this constraint. This matches the requirement given in the question.

Option B:
Option B, sound, is a stronger notion that requires an argument to be both valid and to have all true premises. The stem does not specify that the premises are actually true, only that if they were, the conclusion could not be false, so soundness goes beyond what is stated.

Option C:
Option C, weak, usually describes an inductive argument whose premises provide only limited support for the conclusion. It does not apply to deductive arguments with guaranteed truth preservation.

Option D:
Option D, cogent, refers to an inductive argument that is strong and has true premises, leading to a probably true conclusion. This concept belongs to inductive reasoning, not to the kind of deductive necessity mentioned in the stem.

Statements A, B, C and E correctly explain what a sorites is and how it is examined, while D is false. A sorites links several syllogisms in sequence, often omitting intermediate conclusions in ordinary language, and each link must respect standard syllogistic rules. The final conclusion rests on the chaining of these links, so breaking one undermines the whole structure. UGC NET reasoning passages sometimes hide this pattern, requiring students to reconstruct it. Therefore A, B, C, E only is the correct set.

Option A:
Option A is correct because it gathers all true statements while excluding D, which wrongly treats any unlinked series as a sorites. This reflects the structured nature of polysyllogisms as taught in logic courses.

Option B:
Option B is incomplete since it omits C, thus failing to mention the dependence of the final conclusion on intermediate steps. A, B, E only therefore does not fully characterise a sorites.

Option C:
Option C is wrong because it leaves out A, so B, C, E only does not even define a sorites as a chain of syllogisms, giving only partial information.

Option D:
Option D is incorrect as it omits B and includes only A, C, E, which does not stress that each step must be valid in itself, an important condition for the whole chain to be valid. A, C, E only cannot therefore be accepted.

Paksha is the locus or subject about which an inferential claim is made. In the standard example, the hill functions as paksha because fire is to be proved of it. All discussion of the presence or absence of hetu and sadhya centres around this subject. Thus the entity described in the stem is correctly termed paksha.

Option A:
Option A is correct because paksha identifies the side of the dispute or the case under consideration in the argument. Without specifying the paksha, one would not know where the probandum is supposed to hold. Nyaya's formalism requires clarity about this locus to test the validity of inference.

Option B:
Option B, hetu, is the reason or middle term that links paksha with sadhya, such as smoke, and is conceptually distinct from the subject in which it occurs.

Option C:
Option C, sadhya, is the probandum or property to be established, like fire, and cannot be equated with the subject that bears it.

Option D:
Option D, vyapti, is the universal relation between hetu and sadhya that supports inference and is not the subject of which the property is predicated.

Statements A, B, C, E and F are correct, while D is incorrect. Pakṣa is indeed the subject where the probandum is to be shown, and vyāpti states the invariable relation between hetu and sādhya. Sapakṣa are positive instances with both reason and probandum, and a proper hetu must appear in all such cases and in none of the negative instances, vipakṣa. If hetu appears in vipakṣa, its exclusiveness is broken, making the reason fallacious. Statement D is wrong because vipakṣa are cases where the sādhya is absent and, for a proper hetu, the reason should also be absent there.

Option A:
Option A is incorrect because it omits F, thereby ignoring the important consequence that hetu’s presence in vipakṣa leads to a fallacy. While A, B, C and E describe key concepts, they do not mention what happens when the exclusiveness condition is violated. Thus A, B, C and E only cannot be the full set of correct statements.

Option B:
Option B is correct since it combines A, B, C, E and F, reflecting the standard Nyaya account of pakṣa, vyāpti, sapakṣa, vipakṣa and the condition of a proper hetu. It excludes D, which wrongly describes vipakṣa as places where hetu is present but sādhya is absent. The option therefore matches the real structure of Indian inference theory.

Option C:
Option C is wrong because it accepts D along with the other statements. By treating D as correct, it suggests that hetu is present in vipakṣa, which is the very situation that undermines the validity of the reason. Including D therefore makes this option inconsistent with the conditions for a proper hetu.

Option D:
Option D is incorrect since it drops B, a central explanation of vyāpti, and keeps A, C, E and F only. Without acknowledging vyāpti explicitly, the picture of inference is incomplete, and the presence of D’s error in other options confirms that this reduced set does not accurately represent all true statements.

A particular negative proposition is of the form “Some S are not P”. It denies the predicate for at least one member of the subject class. In the square of opposition, it is classified as an O-type proposition. Therefore the description in the stem corresponds to a particular negative.

Option A:
Option A, universal affirmative, asserts that all members of a class possess a certain property, as in “All S are P”. It does not involve denying something of some members. Hence it cannot be the correct answer.

Option B:
Option B, universal negative, denies the predicate for every member of the subject class, as in “No S are P”. This is too strong compared with the phrase “some members” in the stem. Thus universal negative is not suitable here.

Option C:
Option C correctly names particular negative as the proposition that denies something about some members. It matches both the quantity and the negative quality of the statement described. Therefore this option is correct.

Option D:
Option D, particular affirmative, affirms something of some members, as in “Some S are P”. It lacks the negative component required by the question. Hence particular affirmative is not the right choice.

The only wrong statement here is C; all of A, B, D and E are correct. Effective puzzle solving relies on diagrams and on respecting every given constraint, and some questions explore what is true in all valid arrangements. Random guessing and ignoring constraints is neither efficient nor recommended.

Option A:
Option A is incorrect because it treats both B and C as wrong, even though B is a sound reminder about using all constraints to avoid contradictions.

Option B:
Option B is wrong since it misclassifies A (diagramming) as wrong, even though it is correct.

Option C:
Option C is correct because it singles out C as the lone incorrect statement.

Option D:
Option D is incorrect because it includes D among wrong statements, even though D correctly notes multiple possible arrangements and “true in all cases” questions.

Statements A, B, C and E correctly state the truth conditions and logical role of biconditionals, while D is false. “If and only if” requires that p and q share the same truth value, which can be expressed as two conditionals taken together. It is false exactly when one is true and the other false. Far from being only sufficient, p is both necessary and sufficient for q in a biconditional, so D misdescribes the relation. Recognising this helps with equivalence transformations in UGC NET questions.

Option A:
Option A is incomplete because it omits E, not mentioning how biconditionals feature in exam-style equivalence problems. A, B, C only therefore leaves out a key application of the concept.

Option B:
Option B is wrong since it drops A, thereby failing to state in general that biconditionals are true when p and q match in truth value. B, C, E only provides specific and exam-related facts but lacks the core truth-condition statement.

Option C:
Option C is correct as it gathers all the true statements and excludes D, which restricts the relation to sufficiency alone. This option aligns with standard propositional logic and how biconditionals are tested in symbolic reasoning questions.

Option D:
Option D is incorrect because it omits B, losing the important equivalence of a biconditional with two conditionals. A, C, E only is therefore not acceptable as the right answer.

Statements A, B, D and E correctly present naya as a theory of partial standpoints connected with anekāntavāda and syādvāda, whereas C is false. Each standpoint reveals only one facet of a many-sided reality and thus is incomplete by itself, requiring other nayas for a fuller picture. This supports the Jain doctrine of non-one-sidedness and conditional predication. UGC NET may ask candidates to relate naya to anekāntavāda, so E is true.

Option A:
Option A is incomplete because it omits E, leaving out the explicit exam relevance about relating naya to anekāntavāda. A, B, D only therefore does not fully meet the requirements of the question.

Option B:
Option B is correct since it brings together all the correct statements and excludes C, which wrongly claims that each standpoint is absolutely complete. This option reflects the Jain emphasis on partial viewpoints and matches exam-style questions.

Option C:
Option C is wrong because it leaves out A, not mentioning that naya itself refers to such standpoints, and so B, D, E only provides an incomplete description. Missing A makes the set insufficient.

Option D:
Option D is also incorrect as it omits B, losing the idea that different nayas capture different aspects of the same object. A, D, E only therefore does not give the full set of true statements required.

Viruddha hetu is one whose logical implication contradicts the sadhya instead of supporting it. In such cases, accepting the reason forces one to accept the negation of the intended conclusion. This represents a deep internal conflict in the argument since the chosen ground undermines the thesis. Hence the fallacy described in the stem is viruddha hetvabhasa.

Option A:
Option A is correct because viruddha literally means "opposed" and signals that the reason stands in opposition to the desired conclusion. Nyaya treats this as a serious defect because it reverses the direction of support.

Option B:
Option B, savyabhicara, is a case of irregular association where the reason sometimes accompanies the sadhya and sometimes does not, but it does not necessarily entail the opposite of the conclusion.

Option C:
Option C, badhita, involves a reason whose vyapti is defeated by stronger evidence, not one that itself points to the contradictory property.

Option D:
Option D, satpratipaksha, concerns the presence of an equally strong counter-reason on the other side rather than the inherent tendency of the given reason to prove the opposite.

Trairupya refers to the threefold criteria a reason must meet: presence in the paksha, presence in all sapaksha where the sadhya is present and absence in all vipaksha where the sadhya is absent. These conditions ensure a strong, exceptionless link between hetu and sadhya. Nyaya uses trairupya as a standard test for the adequacy of any proposed hetu. Hence the collective marks mentioned in the stem are called trairupya.

Option A:
Option A, vyapti, denotes the universal concomitance itself but does not enumerate the conditions by which a particular hetu is tested.

Option B:
Option B is correct because trairupya literally means “having three characteristics” and is the technical label for these three necessary conditions.

Option C:
Option C, upadhi, is a limiting condition that qualifies vyapti, often revealing why a purported universal fails; it is not the set of positive marks of a valid reason.

Option D:
Option D, samsaya, signifies doubt and is an epistemic state, not a criterion for assessing hetu.

Anvayavyatireki inference uses a combination of positive instances, where hetu and sadhya occur together, and negative instances, where both are absent, to establish vyapti. This dual confirmation makes the universal relation particularly robust. Nyaya often considers this the most complete way of grounding an inference. Hence the pattern described in the stem is termed anvayavyatireki.

Option A:
Option A is correct because anvaya refers to agreement in presence and vyatireka to agreement in absence, jointly capturing the two-sided evidential support for the relation. This fits the description of both joint presence and joint absence.

Option B:
Option B, kevalavyatireki, restricts itself to negative instances and does not rely on positive sapaksha cases.

Option C:
Option C, kevalanvayi, relies only on positive sapaksha instances with no negative comparison class.

Option D:
Option D, sesavat, is part of the temporal classification of inference (effect to cause) and does not specify how vyapti is established.

In logic, an argument is a structured collection of statements where some are offered as reasons for accepting another statement. The supporting statements are called premises and the supported statement is the conclusion. The defining feature of an argument is this inferential relationship between premises and conclusion. Therefore the set of statements described in the stem is correctly called an argument.

Option A:
Option A is correct because the term argument precisely denotes a group of premises intended to justify a conclusion. It emphasises the idea of rational support rather than mere disagreement or quarrel. In formal reasoning, analysing an argument means evaluating how well its premises support its conclusion. These features match the description given in the question.

Option B:
Option B, explanation, aims to make an already accepted fact intelligible by showing why or how it occurred, rather than to prove that it is true. Explanations presuppose the truth of what they explain, whereas arguments try to establish truth. Hence an explanation does not fit the definition in the stem.

Option C:
Option C, assertion, is simply a statement that claims something is the case without necessarily offering any reasons. An assertion can appear within an argument, but by itself it is not a structured set of premises and conclusion. Therefore assertion is not the correct label here.

Option D:
Option D, example, is a specific instance that may illustrate a general claim or support a premise, but it is only one statement rather than a complete structure of reasoning. Examples can be parts of arguments but are not synonymous with arguments as such.

Illicit process is the general name for the fallacy that occurs when a term is distributed in the conclusion without being distributed in the corresponding premise. This violates the requirement that distribution in the conclusion must be supported by distribution in the premises. The fallacy can take the specific form of illicit major or illicit minor. Hence the description in the stem matches illicit process.

Option A:
Option A, illicit major, occurs when the major term is distributed in the conclusion but not in the major premise. It is one specific type of illicit process. Since the stem speaks in general terms, illicit major alone is too narrow.

Option B:
Option B, illicit minor, arises when the minor term is distributed in the conclusion but not in the minor premise. This is the other specific form of the general fallacy. Again, it does not cover both possibilities mentioned implicitly in the stem.

Option C:
Option C, undistributed middle, is a different fallacy where the middle term is never distributed in either premise. It does not involve a term becoming newly distributed in the conclusion. Therefore undistributed middle is not the correct answer.

Option D:
Option D correctly names illicit process as the overarching fallacy of mis-distribution between premise and conclusion. It captures the improper extension of a term’s scope in the conclusion. Thus illicit process is the most appropriate choice.
