UGC NET Questions (Paper – 1)

A, B, C and E are correct; D is false. Emotional language does not automatically make an argument fallacious; fallacies depend on reasoning structure. Recognising common fallacies helps eliminate wrong options in UGC NET.

Option A:
Option A is incomplete because it omits E (exam usefulness), which is true.

Option B:
Option B is incorrect because it omits A (ad hominem), which is true and part of the set.

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

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

Alaukika pratyaksha encompasses forms of perception that transcend ordinary sensory mechanisms, such as samanyalaksana, jnanalaksana and yogaja perception. These involve special kinds of connections or powers that allow awareness of universals, cross-modal properties or distant objects. Nyaya treats them as exceptional yet still perceptual in character. Thus the collective label for such extraordinary perceptions is alaukika pratyaksha.

Option A:
Option A, laukika, applies only to ordinary empirical perception and stands in contrast to the special cases mentioned in the stem. It is therefore the opposite class.

Option B:
Option B, nirvikalpa, focuses on the level of conceptual articulation and can occur in both ordinary and extraordinary perception, so it does not name the special group of perceptions as such.

Option C:
Option C, savikalpa, again concerns determinacy and may describe either laukika or alaukika perceptions, so it is not the correct classification term here.

Option D:
Option D is correct because alaukika literally means "non-worldly" and is explicitly used in Nyaya to designate these extraordinary perceptual experiences.

A contingency is a statement whose truth value varies across different possible assignments of truth values to its components. It is neither always true nor always false. Most ordinary factual statements have this contingent status. Therefore the description in the stem refers to a contingency.

Option A:
Option A is correct because contingency is the standard name for propositions that can be true in some circumstances and false in others. This intermediate status contrasts with tautologies and contradictions and matches the mixed truth behaviour described.

Option B:
Option B, tautology, is true under every valuation and so lacks the possibility of being false. This does not match the stem’s indication that the statement is sometimes false. Hence tautology is not suitable.

Option C:
Option C, contradiction, is false under every valuation and therefore is never true. The question, however, specifies that the statement is sometimes true, so contradiction cannot be the answer.

Option D:
Option D, theorem, is a result that has been proved within a logical or mathematical system and may or may not be tautological depending on the system. It is not defined by having mixed truth values. Thus theorem is not the best term here.

Statements A, B, C and E are correct. D is false because ad hominem, straw man and false dilemma are informal fallacies (content-based), not formal fallacies determined purely by symbolic form. F is false because emotional language alone does not make an argument ad hominem; the fallacy occurs when a personal attack replaces engagement with reasons. Therefore the correct set of true statements is A, B, C and E only.

Option A:
Option A is incorrect because it omits E, which is also true and important for exam evaluation. So A, B and C only is incomplete.

Option B:
Option B is incorrect because it includes D, which wrongly classifies these as formal fallacies.

Option C:
Option C is incorrect because it includes F, which falsely treats emotional language as automatically ad hominem.

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

A necessary condition is one without which a given event or property cannot occur. If the necessary condition is absent, the event is impossible. However, simply having the necessary condition may not be enough to bring about the event because additional conditions might also be required. Thus the condition described in the stem is a necessary condition.

Option A:
Option A, sufficient, would mean that the condition by itself is enough to produce the event whenever it occurs. This emphasises guarantee rather than requirement, and so does not fit the stem’s description.

Option B:
Option B, causal, indicates that a factor plays some role in producing an effect, but not every cause is necessary and not every necessary condition is a direct cause. The term is therefore too vague for the precise logical relation required.

Option C:
Option C is correct because necessity focuses on what must hold whenever the event occurs. For instance, having oxygen is necessary for ordinary fire, even though oxygen alone cannot start a fire without fuel and ignition. This illustrates the idea that presence is required but not by itself sufficient.

Option D:
Option D, random, connotes lack of systematic relation and is the opposite of being required. A random factor is neither necessary nor reliably connected to the event.

Confirmation bias is a cognitive bias in which individuals focus on evidence that supports their existing views. They may ignore, downplay or reinterpret contrary information. This pattern distorts fair evaluation of arguments and data. Thus the bias described in the stem is called confirmation bias.

Option A:
Option A, anchoring, refers to relying too heavily on an initial piece of information when making judgments. While a cognitive bias, it does not primarily concern seeking confirming evidence. Therefore anchoring is not appropriate here.

Option B:
Option B correctly names confirmation bias as the selective search for and interpretation of evidence that supports prior beliefs. It is a well-known obstacle to objective reasoning. Hence this option fits the description.

Option C:
Option C, availability, involves judging likelihood based on how easily examples come to mind. It depends on memory accessibility rather than desire for confirmation. Thus availability bias is different from the pattern in the question.

Option D:
Option D, recency, is the tendency to give undue weight to recent information. Although related to how evidence is treated, it does not emphasise the confirmation of existing beliefs. Therefore recency bias is not the correct answer.

Purvavat anumana proceeds from knowledge of a presently observed cause to knowledge of a future effect that has not yet occurred. Observing dark, moisture-laden clouds and inferring impending rain exemplifies this pattern. The temporal direction runs from earlier cause to later effect. Consequently, Nyaya classifies such reasoning as purvavat inference.

Option A:
Option A is correct because purvavat literally means "based on the prior" and captures the movement from cause, which is temporally prior, to effect, which is posterior. It highlights one important way in which temporal relations inform inference.

Option B:
Option B, sesavat, goes from an observed effect back to an earlier cause and thus reverses the temporal direction described in the stem.

Option C:
Option C, samanyatodrsta, relies on general uniformities of coexistence rather than specific causal chains and therefore does not fit the cloud–rain example as neatly.

Option D:
Option D, kevalanvayi, classifies inference by the nature of vyapti (only positive instances) rather than by the temporal relationship between cause and effect.

Statements A, B, C and E give a correct overview of syādvāda, while D and F are false. Syādvāda and saptabhaṅgī emphasise that predications are made from particular standpoints, so apparently opposite claims can both be conditionally true. This does not amount to radical scepticism but to a nuanced, many-sided account of truth. UGC NET usually tests the general idea of conditional predication rather than requiring exhaustive enumeration of all seven forms. Therefore A, B, C and E only is the correct combination.

Option A:
Option A is correct because it captures both the conceptual core of syādvāda and its exam-level treatment without endorsing the extremes stated in D and F. It recognises the relativity of statements without denying the possibility of knowledge. This matches how Jaina logic is typically presented in Paper 1 materials.

Option B:
Option B is incorrect since it includes D, which claims unconditional absolute truth from all standpoints, contradicting the very idea of syādvāda. Syādvāda insists on conditionality rather than absolute unconditional claims. Including D therefore makes the option unsound.

Option C:
Option C is wrong as it incorporates F, which mislabels syādvāda as pure scepticism, and it omits A, so the central role of “syāt” is no longer stated. Without A and with F, the nature of Jaina logic is distorted.

Option D:
Option D is also incorrect because it includes F and omits B, thereby losing explicit reference to the sevenfold scheme while accepting a false characterisation of the doctrine. This combination cannot be chosen as correct.

Upadhi is a special condition that, when recognised, shows that an alleged universal relation holds only under certain circumstances. It explains why a seemingly general vyapti like “wherever there is smoke there is fire” fails in cases such as wet fuel, where smoke occurs without fire. Identifying the upadhi refines the vyapti to make it genuinely universal. Therefore the restricting condition described in the stem is called upadhi.

Option A:
Option A, trairupya, lists the positive conditions that a valid hetu must satisfy; it does not name the factor that exposes a hidden limitation in vyapti.

Option B:
Option B, paksha, is the specific subject of inference, not a condition governing the general relation between hetu and sadhya.

Option C:
Option C is correct because upadhi literally means “subsidiary condition” and functions in Nyaya to block overgeneralisation by specifying the exact scope of a true universal.

Option D:
Option D, dravya, is the category of substance and has no direct role as a limiting factor in logical relations.

Saying that p is necessary for q means that q cannot occur without p. This can be formally expressed as “if not p, then not q”. The two formulations always share the same truth conditions. Therefore they stand in a relation of logical equivalence.

Option A:
Option A, contrariety, concerns pairs of propositions that cannot both be true but may both be false. It does not capture the idea that two statements always have matching truth values. Hence contrariety is not the correct answer.

Option B:
Option B correctly identifies equivalence as the relation where two statements are true and false in exactly the same circumstances. The natural-language claim about necessity and the conditional “if not p, then not q” illustrate this. Thus equivalence is the best choice.

Option C:
Option C, subalternation, relates universal and particular propositions in the traditional square of opposition. It does not describe a mutual sameness of truth conditions. Therefore subalternation is not appropriate here.

Option D:
Option D, independence, refers to propositions whose truth values do not systematically constrain each other. This is the opposite of equivalence. Consequently independence cannot be the correct answer.

Statements A, C, D and E correctly describe how “and”, “or” and “unless” are typically handled in reasoning questions, whereas B and F are false. Conjunction requires both parts to be true, and “or” is usually read inclusively unless there is strong contextual pressure otherwise. “P unless q” is standardly taken as “if not q then p”, and misreading these connectives often leads to wrong options being chosen. B incorrectly makes “or” always exclusive, and F ignores the interpretative work needed when mapping language to logic. Therefore A, C, D and E only is the correct combination.

Option A:
Option A is incomplete because it omits D and E, leaving out both the usual translation of “unless” and the warning about misinterpretation. While A and C are true, they do not capture the full complexity of how connectives work in questions. Thus this option is not sufficient.

Option B:
Option B is also incomplete, as it fails to include E and therefore misses the explicit link between misreading connectives and exam errors. A, C and D are correct but do not mention the consequences of misinterpretation. Hence this option cannot be accepted.

Option C:
Option C is wrong since it omits A and includes only C, D and E. Without A, the basic treatment of “and” is missing, which is a key connective in reasoning. The omission makes the description of connectives less complete.

Option D:
Option D is correct because it gathers all relevant true statements about the interpretation of these connectives while excluding B and F, which exaggerate exclusivity and perfect matching between language and logic. It thus matches both logical theory and exam practice.

Nigamana is the concluding member of the Nyaya five-step inference where the original thesis (pratijna) is restated in light of the supporting reasoning. After presenting hetu, drstanta and upanaya, nigamana summarises that the sadhya has been established in the paksha. It functions similarly to the conclusion of a syllogism in Western logic. Therefore the final step described in the stem is called nigamana.

Option A:
Option A, pratijna, is the initial statement of the thesis to be proved, not its final restatement. It opens the inference rather than closing it. Thus it does not fit the description.

Option B:
Option B, hetu, is the reason or ground offered to support the thesis, typically presented as the second member of the inference. It explains why the thesis should be accepted but is distinct from the concluding restatement.

Option C:
Option C, upanaya, is the step that applies the general concomitance shown in the drstanta to the specific paksha, bridging universal and particular. It precedes, rather than replaces, the final conclusion.

Option D:
Option D is correct because nigamana explicitly names the act of drawing together the prior steps into a final, affirmed conclusion. It completes the inferential chain and signals that the argument has achieved its goal.

B, C, D and E are correct; A is false. The negation of “All S are P” is “Some S are not P”, not “No S are P”. B gives the correct negation of “Some S are P”. C and D are De Morgan’s laws. E is true about exam utility.

Option A:
Option A is incomplete because it omits E (which is true and relevant), so it does not include all correct statements.

Option B:
Option B is incorrect because it includes A, which gives the wrong negation of “All S are P”.

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

Option D:
Option D is incorrect because it includes A, which is false, so it cannot be the correct set.

Statements A, B, C and E are correct, whereas D and F are false. Diagrams and symbolic notations are widely recommended for arrangement problems because they externalise information and constraints. When a trial placement yields a contradiction, it signals that assumptions must be changed, and elimination is a powerful strategy when several possibilities exist. D is wrong because some puzzles may have multiple valid configurations, and F is wrong because disorganised reading usually makes problems harder, not easier. Hence A, B, C and E only is the correct combination.

Option A:
Option A is correct because it collects the main effective strategies for arrangement problems and excludes unrealistic claims about uniqueness and the effect of random reading. It reflects both reasoning principles and practical exam techniques. Therefore this option best represents the correct statements.

Option B:
Option B is incomplete since it omits E, the explicit mention of elimination as a useful tool. While A, B and C describe diagramming and revision, they leave out an important problem-solving technique. Thus A, B and C only cannot be accepted.

Option C:
Option C is wrong because it includes F, which wrongly asserts that random order reading has no impact on difficulty. In fact, organising conditions often simplifies reasoning. This option also omits A, removing an important recommendation about drawing diagrams.

Option D:
Option D is incorrect because it accepts F and omits B. Without B, the benefit of formalising clues is lost, and including F contradicts widely shared problem-solving advice. Therefore A, C, E and F only is not a valid answer.

A and B are correct definitions. C is false because valid arguments can have false premises. D is false because a true conclusion can come from invalid reasoning. E is false because a sound argument’s conclusion must be true. Thus only A and B are correct.

Option A:
Option A is incomplete because it omits B (soundness definition).

Option B:
Option B is correct because it includes exactly the two true statements.

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

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