UGC NET Questions (Paper – 1)

Statements A, B, C, D and E accurately describe the five members of the Nyaya syllogism, whereas F is incorrect. Pratijñā is the initial thesis, hetu provides the reason, udāharaṇa states the universal concomitance with an example, and upanaya links that rule to the pakṣa. Nigamana then concludes by restating the thesis in light of these steps. Pakṣa is not absent; it is the locus where the sādhya is to be established, so F misrepresents its role. Therefore A, B, C, D and E only is the correct combination.

Option A:
Option A is correct because it collects exactly the five true statements that correspond to the traditional Nyaya account of reasoning. It excludes F, which wrongly claims that pakṣa has no logical role, even though it is central as the subject of inference. This combination thus reflects both the structure and intent of the pañcāvayava form.

Option B:
Option B is incorrect since it omits E, failing to mention nigamana, the concluding member that restates the thesis. Without E, the picture of the five-membered structure is incomplete. Consequently A, B, C and D only cannot be chosen as correct.

Option C:
Option C is wrong because it includes F and omits A. Including F accepts the false claim that pakṣa is absent, and leaving out A ignores the naming of pratijñā as the first member. Both problems make B, C, D, E and F only an unacceptable option.

Option D:
Option D is incorrect as it accepts F along with A, C and D and leaves out B and E. Omitting hetu and nigamana removes crucial steps, while adopting F distorts the status of pakṣa. Therefore A, C, D and F only does not represent the set of correct statements.

Drstanta is the example that makes the universal relation between hetu and sadhya vivid and acceptable to the listener. It usually cites a familiar case where both occur together, such as fire and smoke in a kitchen. This helps to ground the claim of vyapti empirically. Therefore the example described in the stem is called drstanta.

Option A:
Option A is correct because drstanta literally means “seen instance” and functions as the third component of the Nyaya inference, combining a general statement with an example. It is central in showing that the hetu–sadhya connection is not merely speculative.

Option B:
Option B, paksha, is the specific subject of inference like the hill, not the exemplar case used to demonstrate vyapti.

Option C:
Option C, upanaya, is the application step that links the general rule shown by the drstanta to the paksha. It comes after the example is given.

Option D:
Option D, nigamana, is the concluding restatement of the thesis, not the illustrative middle step.

Yogaja pratyaksha is an extraordinary perception said to arise from intense yogic practice, allowing direct awareness of subtle objects or distant events. It does not rely on normal sense-object contact and is considered a special capacity of advanced practitioners. Nyaya acknowledges this possibility as part of its broader theory of perception. Therefore the supernormal awareness described in the stem is yogaja pratyaksha.

Option A:
Option A, samanyalaksana, concerns perception of universals through instances and does not focus on the yogic origin of cognition. It can occur without any special meditative discipline.

Option B:
Option B, jnanalaksana, is mediated by traces of previous cognitions and typically illustrates cross-modal or residual perceptions rather than the supernormal powers attributed to yogis.

Option C:
Option C is correct because yogaja literally means "born of yoga" and designates perceptions that owe their existence to yogic concentration rather than to ordinary processes.

Option D:
Option D, laukika, refers to everyday sense perception and explicitly contrasts with the extraordinary status of yogaja experiences.

Bhatta Mimamsa extends the pramana list to six by adding arthapatti and anupalabdhi to the more common four. They argue that certain kinds of knowledge, such as awareness of absence, cannot be reduced to perception or inference alone. This expansion is tied to their concern with interpreting Vedic injunctions and ritual prescriptions accurately. Therefore the standard count of pramanas in Bhatta Mimamsa is six.

Option A:
Option A, three, would drastically understate the epistemic resources recognised in Bhatta Mimamsa and ignore their elaborate arguments for additional pramanas. It would conflate them with schools like Samkhya that have a more restrictive list.

Option B:
Option B, four, corresponds to classical Nyaya but fails to capture the distinctive Mimamsa claim about arthapatti and anupalabdhi. Mimamsakas see these extra pramanas as necessary for explaining certain kinds of Vedic and empirical knowledge.

Option C:
Option C, five, would still omit one of the two special pramanas championed by this school. While some philosophers accept five, the Bhatta position is characteristically six.

Option D:
Option D is correct because Bhatta Mimamsa explicitly enumerates six pramanas to secure a comprehensive account of both worldly and scriptural cognition.

For an E-type universal negative proposition like "No S are P", simple conversion is valid and yields "No P are S". This new statement preserves both the quantity and quality of the original while exchanging subject and predicate. The two propositions express the same exclusion relation between the classes. Hence the correct converted form is "No P are S".

Option A:
Option A, "All P are S", changes both the quantity and the quality of the original statement. It asserts a universal affirmative rather than a universal negative and therefore cannot be logically equivalent to "No S are P".

Option B:
Option B, "Some P are S", asserts an existential particular affirmative that contradicts the universal exclusion in the original. It would claim overlapping membership where the original denies any overlap. Thus it is not a valid conversion.

Option C:
Option C is correct because the conversion of an E proposition simply reverses the positions of subject and predicate while maintaining "no" as the quantifier. This keeps the meaning that the two classes do not share any members, which is consistent with the original statement.

Option D:
Option D, "Some P are not S", changes the form to a particular negative and does not preserve the universal denial of overlap. It allows the possibility that some P are S, which conflicts with the original universal negative.

Hetvabhasa literally means "that which appears like a hetu" and refers to reasons that mimic valid middle terms but do not actually establish the sadhya. Such defects may arise from irregularity, contradiction, absence in the paksha or being defeated by stronger evidence. Identifying hetvabhasas is crucial for spotting fallacies in inference. Thus the deceptive reason described in the stem is called hetvabhasa.

Option A:
Option A, vyapti, is the genuine universal concomitance between hetu and sadhya and is a sign of correctness, not of fallacy. It underwrites valid inference rather than indicating error.

Option B:
Option B is correct because hetvabhasa is the umbrella term for several standard types of fallacious reasoning in Nyaya, such as savyabhicara, viruddha and asiddha. Each example illustrates how an apparent reason can fail logically.

Option C:
Option C, drstanta, is the illustrative example used to support the inference and is not itself the defective reason, though it can reveal defects.

Option D:
Option D, paksha dharma, simply indicates a property present in the paksha and may or may not function as a suitable hetu; it is not inherently fallacious.

Statements A, B, C and D accurately describe reductio ad absurdum and its relation to prasaṅga, while E is false. In reductio, we assume the opposite of what we want to prove and derive a contradiction or absurd consequence, forcing us to reject that assumption and accept its negation. Buddhist prasaṅga uses a similar technique against an opponent’s thesis. However, merely having contradictory premises does not automatically constitute a proper reductio; the contradiction must be shown to arise from the specific assumption under test. Thus E is the only incorrect statement.

Option A:
Option A is correct because it singles out E as the sole wrong statement and preserves the correct description of reductio and its dialectical use in A, B, C and D. This option mirrors the structured method taught for proof by contradiction.

Option B:
Option B is incorrect since it also marks C as wrong even though C correctly states what is concluded when a contradiction arises from the assumed negation. C and E only therefore misclassifies a crucial step in reductio as incorrect.

Option C:
Option C is wrong because it treats D as wrong along with E, despite D accurately noting the use of prasaṅga in Buddhist debates. D and E only thus fails to respect the historical connection.

Option D:
Option D is also incorrect since it includes B among the wrong statements, even though B correctly explains that we derive a contradiction or unacceptable consequence from the assumption. B, D and E only therefore cannot be accepted as the correct answer.

Statements A, B, D and E accurately state Nyaya’s four pramāṇas and their exam relevance, while C is false. Classical Nyaya recognises pratyakṣa, anumāna, upamāna and śabda as pramāṇas, and reserves arthāpatti and anupalabdhi mainly for other schools such as Mīmāṃsā and Advaita Vedānta. Śabda is indeed reliable testimony, and UGC NET questions often ask candidates to recall this list. Thus A, B, D, E only comprises the correct set of statements.

Option A:
Option A is incomplete because it omits E, failing to link this doctrinal point directly to UGC NET question patterns. A, B, D only therefore does not fully address the exam focus of the stem.

Option B:
Option B is correct since it includes all true claims and excludes C, which wrongly extends Nyaya’s list of pramāṇas. This option reflects standard Indian logic textbooks used for UGC NET preparation.

Option C:
Option C is wrong as it leaves out A, losing the explicit enumeration of Nyaya’s four pramāṇas, and thus B, D, E only presents an incomplete picture of the system.

Option D:
Option D is incorrect because it includes C along with A, B and D, wrongly suggesting that Nyaya adds arthāpatti and anupalabdhi as separate pramāṇas. A, B, C, D only therefore mixes a false claim with true ones.

The post hoc fallacy, often summarised as “after this, therefore because of this”, mistakes mere temporal order for genuine causation. It assumes that because event A precedes event B, A must have caused B, ignoring other possible causes or coincidental sequences. Proper causal reasoning requires additional evidence such as mechanisms, controlled comparisons or repeated patterns, not just timing. Thus the error described in the stem is the post hoc fallacy.

Option A:
Option A, slippery slope, warns that a small initial step will lead inevitably to a chain of increasingly severe consequences, usually without adequate support for the inevitability. It does not centre on inferring causation solely from temporal sequence.

Option B:
Option B is correct because post hoc specifically captures the confusion between succession in time and causation. Recognising this fallacy reminds us that correlation, especially when inferred only from “came after”, is not sufficient to establish cause.

Option C:
Option C, red herring, distracts from the main issue by introducing an irrelevant topic, but it does not rely on any assumption about the order of events.

Option D:
Option D, weak analogy, draws an inference from a comparison where the similarities are not strong or relevant enough to support the conclusion; again, it is different from the time-based error in question.

In traditional logic, a universal affirmative proposition asserts that every member of the subject class belongs to the predicate class. It is symbolised as "All S are P" and classified as an A-type proposition on the square of opposition. This structure combines universal quantity with affirmative quality. Therefore the proposition described is correctly termed a universal affirmative.

Option A:
Option A is correct because universal affirmative explicitly captures the idea of a positive assertion about all members of a class. It is distinguished from other categorical forms by its scope over the entire subject class and its affirming character. This matches exactly the form "All S are P" given in the question.

Option B:
Option B, universal negative, denies membership for all subjects in the predicate class, as in "No S are P". It has universal quantity but negative quality, which is not what the stem describes. Thus universal negative is not suitable here.

Option C:
Option C, particular affirmative, asserts that at least one member of the subject class belongs to the predicate class, as in "Some S are P". It does not speak about all members and therefore fails to fit the description.

Option D:
Option D, particular negative, denies the predicate of at least one subject, as in "Some S are not P". It differs in both quantity and quality from the universal affirmative type. Hence particular negative cannot be the correct answer.

Statements A, B, D and E correctly describe formal and informal fallacies and their exam presence, whereas C is clearly wrong. A formal fallacy is a structural mistake, while informal fallacies arise from content, language or context. Modus ponens is a valid form and thus not a fallacy at all, so calling it a formal fallacy is incorrect. Recognising patterns like ad hominem and straw man is important for UGC NET reasoning, so D and E are true.

Option A:
Option A is correct because it correctly isolates C as the single false statement while preserving the accurate explanations in A, B, D and E. It reflects the distinction between valid forms and mistaken forms in logical analysis.

Option B:
Option B is wrong since it treats A as part of the wrong set, even though A properly defines what a formal fallacy is. A and C only therefore misclassifies a true definition as incorrect.

Option C:
Option C is also incorrect because it groups D with C, implying that ad hominem and straw man are wrongly described, whereas they are rightly cited as informal fallacies. C and D only thus misrepresents the list.

Option D:
Option D is wrong as it further extends the misclassification by adding B to the wrong set, despite B accurately describing informal fallacies. B, C and D only therefore fails to preserve the correct information needed for exam preparation.

Statements A, B, C, D and E correctly summarise the traditional and modern views of the square of opposition, while F is false. The traditional square treats A and E as contraries and I and O as subcontraries, and maintains that contradictory pairs cannot both be true or both be false. Modern logic largely drops contrariety and subcontrariety due to the rejection of existential import, but it keeps the contradictory relations intact. F is wrong because subalternation from universal to particular does not automatically hold under the modern, non-existential reading. Therefore A, B, C, D and E only is the correct combination.

Option A:
Option A is correct because it includes all the true statements and excludes only F, which misstates the scope of subalternation in modern logic. It captures both the traditional structure and the modifications introduced by the Boolean interpretation. This makes it the only option that fully matches accepted logical theory.

Option B:
Option B is incomplete because it omits E, which correctly notes that contradictory relations remain valid in both interpretations. Without E, the description of what survives in the modern view is incomplete. Hence A, B, C and D only does not represent the full set of correct statements.

Option C:
Option C is wrong because it includes F along with B, C, D and E. Including F treats subalternation as always valid in modern logic, which is not the case when universals are not assumed to have existential import. This error makes the combination inconsistent with standard textbook accounts.

Option D:
Option D is incorrect because it leaves out B and E and wrongly includes F. B is needed to characterise subcontraries, and E is needed to show what survives in the modern view. With these omissions and the inclusion of F, A, C, D and F only cannot be accepted as the correct set.

Nigamana is the final step in the five-membered inference where the conclusion is explicitly stated. It restates the original thesis as now established by the preceding steps. This marks the completion of the inferential process. Hence the culminating step mentioned in the stem is called nigamana.

Option A:
Option A, pratijna, is the initial proposition or thesis to be proved. It begins the inferential sequence rather than concluding it. Therefore pratijna is not the culminating step.

Option B:
Option B, hetu, presents the reason or sign used to support the thesis. It appears early in the inferential chain and does not mark its completion. Thus hetu is not the correct answer.

Option C:
Option C, drstanta, offers an example that illustrates the universal relation between hetu and sadhya. It clarifies the inference but does not represent its final step. Hence drstanta is not appropriate here.

Option D:
Option D correctly names nigamana as the concluding statement of the five-membered argument. It signals that the proposition has been logically established. Therefore nigamana is the best choice.

Statements A, B, C and E present the standard Nyaya account of the three key elements of inference, whereas D is false. The pakṣa is the locus where something is to be demonstrated, sādhya is the probandum, and hetu is a pervaded sign that must be present in the pakṣa. If hetu fails to be present in the pakṣa, the inference collapses, so D contradicts a basic rule. UGC NET often asks candidates to identify these elements in classical examples, which makes E correct.

Option A:
Option A is incomplete because it omits E, ignoring the explicit exam application mentioned in the stem. Although A, B and C are true, A, B, C only does not cover all the correct statements about the topic.

Option B:
Option B is wrong since it leaves out C, which specifies the relation of hetu to sādhya via vyāpti, an essential feature of inferential reasoning. A, B, E only therefore does not fully describe the triad.

Option C:
Option C is correct as it includes all accurate claims about the roles of pakṣa, hetu and sādhya and their importance in UGC NET questions while excluding D, which denies the requirement that hetu be present in the subject. This combination matches standard Indian logic presentations.

Option D:
Option D is incorrect because it omits A, failing to mention the pakṣa explicitly, and therefore gives only a partial picture. B, C, E only does not satisfy the requirement of listing all correct statements.

Statements A, B, C, D and E are all correct descriptions of necessary and sufficient conditions, whereas F is false. Sufficiency requires that p’s truth guarantees q, and necessity means q is required for p. When a condition is both necessary and sufficient, the two statements are equivalent, and such cases do exist in logic and mathematics. Misunderstanding these notions can easily produce fallacies in exam questions, so E is also correct, while F contradicts the definition of a necessary condition by suggesting an impossible relation.

Option A:
Option A is incomplete because it omits E, failing to include the practically important warning about exam inferences. While A, B, C and D correctly outline theoretical relations, they do not address how confusion between them leads to mistakes in reasoning. Therefore A, B, C and D only does not contain all the correct statements provided.

Option B:
Option B is correct since it gathers all five true statements A, B, C, D and E and excludes F, which misrepresents necessity. It integrates the conceptual link between necessity, sufficiency and equivalence with the practical impact on inferential errors. Thus it accurately reflects the understanding expected in UGC NET Paper 1.

Option C:
Option C is incorrect because it leaves out D, which notes that a condition may indeed be both necessary and sufficient in certain contexts. Without D, the answer ignores an important nuance about how conditions can combine. The omission means this option does not fully represent the set of correct statements.

Option D:
Option D is wrong because it omits A, the basic link between sufficiency and conditional implication, and includes only B, C, D and E. Without A, the account of sufficient conditions is incomplete, even though the other four statements are true. Hence B, C, D and E only cannot be the right combination.
