UGC NET Questions (Paper – 1)

A, B and C correctly describe causal reasoning (difference-making, often-inductive inference, and the need to consider alternatives). E is true because UGC NET DI sets may test weak vs strong causal claims. D is false since correlation alone does not always establish causation. Hence 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 context).

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

Option D:
Option D is incorrect because it omits B (inductive nature) and includes D (false).

Viruddha hetu is one whose logical implication contradicts the very claim it is supposed to support. When such a reason is accepted, it compels assent to the opposite of the intended conclusion. This makes the argument self-defeating, as the chosen ground undermines rather than upholds the thesis. Nyaya treats viruddha as a serious and obvious fallacy.

Option A:
Option A, asiddha, highlights the absence of the hetu in the paksha and does not involve proving the contrary property. It is a defect of non-establishment, not of contradiction.

Option B:
Option B is correct because viruddha literally means "opposed" and is reserved for reasons that logically favour the negation of the sadhya. It captures the idea of a middle term pulling the argument in the reverse direction.

Option C:
Option C, badhita, arises when a supposed vyapti is overruled by a stronger pramana, not when the hetu itself points to the opposite conclusion.

Option D:
Option D, satpratipaksha, refers to the presence of an equally strong counter-reason on the other side, rather than to the internal contrariety of a single hetu.

Statements A, B, C and E correctly describe how propositions are understood in logic and how they are used in reasoning questions, while D and F are false. A is right that propositions are truth-apt contents of declarative sentences, and B is right that questions and commands are normally excluded. C is correct that different sentences can express the same proposition, and E rightly notes that identifying propositions helps in argument analysis. D is wrong because some grammatical sentences lack a clear truth value, and F is wrong because long or complex sentences can also express propositions.

Option A:
Option A is correct because it includes exactly A, B, C and E, which are the four true statements in the list. It avoids D, which overgeneralisers grammaticality, and F, which incorrectly restricts propositions to short sentences. This combination matches the logical treatment of propositions and their role in UGC NET reasoning.

Option B:
Option B is incorrect because it omits statement E, which truly points out the exam relevance of identifying propositions. Although A, B and C are all true, leaving out E means this option does not contain all the correct statements. Hence it gives only a partial picture of the role of propositions.

Option C:
Option C is wrong because it includes F, which falsely claims that only short simple sentences can express propositions, and it also omits A, the basic definition. Without A, the notion of a proposition as a truth-apt content is lost. Including a false statement and excluding a central true one makes this combination unacceptable.

Option D:
Option D is incorrect because it includes F and leaves out B. By accepting F, it endorses an unjustified restriction on propositions, and by omitting B it ignores the standard exclusion of questions and commands. This mixture of omission and error prevents the option from representing the full set of correct statements.

In classical Indian logic, pratyaksha is the pramana that denotes direct perception. It is knowledge gained through immediate contact of the senses with their objects, free from error and distortion. This form of cognition is considered foundational for empirical awareness. Hence the type of knowledge described in the stem is called pratyaksha.

Option A:
Option A, anumana, refers to inference, where knowledge arises from reasoning based on signs or evidence. It is mediated, not direct, and therefore differs from sense perception. So anumana is not the right answer.

Option B:
Option B correctly identifies pratyaksha as sense perception or direct awareness of objects. It contrasts with inferential and testimonial sources of knowledge. Therefore pratyaksha is the most accurate term here.

Option C:
Option C, upamana, denotes knowledge by comparison or analogy, such as learning about an unknown object by comparing it with a known one. This is again different from immediate sensory contact. Thus upamana does not fit the description.

Option D:
Option D, sabda, is verbal testimony, especially authoritative or scriptural knowledge. It relies on trustworthy speakers rather than direct sensory experience. Therefore sabda cannot be the correct answer to this question.

Obversion is an immediate inference in which a categorical proposition is transformed by switching from affirmative to negative or vice versa and replacing the predicate with its complement. For example, “All S are P” becomes “No S are non-P”. This operation preserves logical equivalence for all four standard forms. Hence the result of the process described in the stem is called the obverse of the original proposition.

Option A:
Option A, conversion, involves interchanging the subject and predicate terms while keeping quantity and quality the same or appropriately modified, as in converting “No S are P” to “No P are S”. It does not require introducing the complement of the predicate.

Option B:
Option B is correct because obversion is uniquely defined by the combination of quality change and predicate complementation. It provides a reliable way of generating an equivalent statement that often clarifies the logical content.

Option C:
Option C, contraposition, is obtained by interchanging subject and predicate and negating both, which is a different transformation usually applied to conditionals and some categorical forms. It is not the simple quality change with predicate complement described in the question.

Option D:
Option D, distribution, concerns whether a term refers to all members of its class within a proposition and is not the name of any immediate inference. It does not describe the operation of forming an equivalent proposition.

A contradiction is a statement that cannot be true under any assignment of truth values to its components. Its logical form guarantees falsity in every possible case. Such statements are logically impossible and indicate inconsistency. Therefore the compound statement described in the stem is a contradiction.

Option A:
Option A, tautology, is always true and thus stands opposite to contradiction. It does not match the condition of being false in all valuations. Hence tautology is not the correct answer.

Option B:
Option B, contingency, can be true in some cases and false in others. It lacks the universal falsity required by the stem. Therefore contingency is not appropriate here.

Option C:
Option C, paradox, is an informal term for seemingly self-contradictory statements, but not every paradox is logically false under all valuations. The stem instead describes the technical notion of contradiction. Thus paradox is not the best label.

Option D:
Option D correctly names contradiction as the form that is false in every possible situation. Recognising contradictions is crucial for testing the consistency of logical systems. Hence contradiction is the correct choice.

Pramana is the technical term used in Indian epistemology to denote a reliable instrument or means of valid knowledge. It focuses on the process or channel through which true cognition arises, such as perception or inference. By identifying pramana, philosophers can distinguish trustworthy cognitions from error. Therefore, the generic means described in the stem is correctly called pramana.

Option A:
Option A is correct because pramana names the epistemic instrument, like perception or testimony, that causally and justificatorily connects the knower to the object. It captures the idea of a route that, when functioning properly, produces non-contradicted, fruitful cognition. In pramana theory, the classification of different pramanas is central to understanding how knowledge is grounded.

Option B:
Option B, prameya, denotes the object that is known, such as a pot or a sound, and is thus the target of knowledge rather than the means that produces it. Treating prameya as a means would confuse the distinction between epistemic instrument and object. Hence prameya cannot fill the blank in this definition.

Option C:
Option C, pramiti, is the valid cognition itself, the resultant knowledge occurring in the mind after the pramana has operated. It is an epistemic product rather than the instrumentive factor highlighted in the question. Identifying pramiti with pramana would collapse the process–product distinction.

Option D:
Option D, pramata, refers to the knower or epistemic subject who employs pramanas to gain knowledge of prameyas. While essential to the knowledge situation, the pramata is not described as the instrument that generates cognition. Therefore pramata does not match the stem.

In logical reasoning, the conclusion is the claim that the arguer wants the audience to accept. It is presented as being supported by one or more premises. The entire structure of the argument is organised so that the premises provide reasons for believing the conclusion. Hence the statement described in the stem is properly called the conclusion.

Option A:
Option A, premise, refers to a supporting statement that provides evidence or reasons for the conclusion. While premises are crucial components of an argument, they do not express the final claim being argued for. Therefore premise does not fit the description given.

Option B:
Option B is correct because conclusion designates the endpoint of the reasoning process, the statement for which support is being offered. When we evaluate an argument, we specifically ask whether the premises, if true, make the conclusion acceptable. This role matches exactly what the question describes.

Option C:
Option C, example, is a particular instance used to illustrate or clarify a general claim. Examples can support understanding but are not, by themselves, the claim that the whole argument is structured to establish. Thus example is not the right label here.

Option D:
Option D, question, seeks information and is not usually assigned a truth value or treated as the final claim in an argument. While questions may motivate inquiry, they do not function as conclusions within standard logical analysis. Hence question is not appropriate.

Samavaya is the special relation posited by Nyaya-Vaisheshika to account for cases where two entities are so intimately connected that they cannot exist separately, such as a substance and its qualities or a whole and its constituent parts. Ordinary relations like contact are deemed insufficient to explain this inseparability. Samavaya is therefore treated as an eternal, irreducible category. Hence the bond mentioned in the stem is called samavaya.

Option A:
Option A, samanya, denotes universals that are common to many individuals and does not name a relation between distinct entities. It explains similarity, not inseparable connection.

Option B:
Option B is correct because samavaya directly addresses the ontological need for a relation that binds co-located but numerically distinct entities into unified complexes. It plays a crucial role in the padartha framework.

Option C:
Option C, vishesha, is the category of particularity that differentiates ultimate entities from one another and is not the relation holding between them.

Option D:
Option D, abhava, signifies non-existence or absence and cannot be the glue that unites substances with their qualities or parts.

Paksha refers to the subject about which something is to be inferred, such as the hill in "The hill is fiery because it has smoke". It is the locus where the reason is observed and where the property to be proved is asserted. Identifying the paksha makes clear the scope of the inferential claim. Hence the subject described in the stem is called paksha.

Option A:
Option A, sapaksha, is the collection of similar instances where both hetu and sadhya are present, used to support vyapti. These are positive examples, not the particular subject under direct consideration. Therefore sapaksha is not correct.

Option B:
Option B, vipaksha, denotes dissimilar instances where the sadhya is absent and typically the hetu should also be absent. They test the universality of the vyapti but are not the main locus of inference. Thus vipaksha does not fit the stem.

Option C:
Option C is correct because paksha explicitly names the individual case about which the inference is being made. It is central to understanding who or what the conclusion is intended to apply to.

Option D:
Option D, hetu, is the reason or middle term cited to justify the sadhya, such as "having smoke". It is a property of the paksha rather than the paksha itself, so it cannot be the answer here.

Statements A, B and C correctly define converse, inverse and contrapositive, while E and F state correct logical and exam-related facts, and D is false. A conditional is not equivalent to its converse, but it is equivalent to its contrapositive. When test-takers mistake a conditional for its converse, they often commit the fallacy of affirming the consequent. Therefore the set of correct statements is A, B, C, E and F only.

Option A:
Option A is incomplete because it omits F, leaving out the important note that this confusion gives rise to a specific fallacy tested in exams. While A, B, C and E are true, they do not mention the reasoning error that is pedagogically central. Hence this combination is not fully adequate.

Option B:
Option B is correct since it collects all the true statements about transformations of conditionals and their logical relations. It keeps the equivalence with the contrapositive and highlights the risk of misreading as a converse. By excluding D, which overstates equivalence, it stays faithful to standard logical theory.

Option C:
Option C is incorrect because it accepts D, wrongly claiming that a conditional is always equivalent to its converse. This would treat “If it is a square then it is a rectangle” as equivalent to “If it is a rectangle then it is a square”, which is not correct. Including D therefore makes the option unsound.

Option D:
Option D is wrong because it leaves out A and includes F but also omits one of the key definitional statements. Without A, the notion of converse is not clearly present, and the option does not gather all true statements. Thus it cannot be chosen as correct.

A, C and E are correct; B and D are false. Nyaya uses tarka as an auxiliary tool to rule out alternatives in establishing vyāpti, typically via unacceptable-consequence reasoning. It is not treated as an independent pramāṇa equal to perception/inference, and vyāpti establishment does involve such supportive reasoning.

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

Option B:
Option B is incorrect because it includes B (false: tarka is not an independent pramāṇa of equal status).

Option C:
Option C is incorrect because it includes D (false: Nyaya does use tarka in the process).

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

Statements A, B, C and E correctly summarise the requirement that a categorical syllogism use exactly three terms and how violations occur, while D is false. Four distinct terms, whether through outright multiplication or ambiguity of a term, break the three-term rule and generate the fallacy of four terms. A two-term argument is not automatically valid; it may fail other rules. UGC NET questions do ask candidates to detect such fallacies, so E is also true. Hence A, B, C, E only constitutes the right set.

Option A:
Option A is incomplete because it omits E, failing to mention the explicit exam relevance that the question highlights. A, B, C only therefore does not fully answer the stem.

Option B:
Option B is wrong as it leaves out C, ignoring that ambiguity of the middle term can effectively produce four terms even if the same word is used. A, B, E only thus misses an important mechanism of the fallacy.

Option C:
Option C is correct because it collects all true descriptive and exam-related statements and excludes D, which incorrectly declares any two-term syllogism valid. This matches standard treatments of syllogistic structure.

Option D:
Option D is incorrect since it includes D, the false claim about two-term syllogisms, and so B, C, D, E only mixes correct and incorrect information. It therefore cannot be accepted as the correct option.

Circular reasoning occurs when an argument's conclusion is already embedded, explicitly or implicitly, in its premises. Instead of providing independent support, the premises merely restate the claim in different words. This gives the illusion of justification while in fact assuming what needs to be demonstrated. Consequently, the argument fails to advance rational grounds for belief and is rightly criticised as circular.

Option A:
Option A is correct because circular arguments “go in a circle,” starting from what they purport to end with. Even if the conclusion is true, the reasoning does not help to establish it, since one can only accept the premises if one already accepts the conclusion.

Option B:
Option B, analogical, refers to arguments that reason from similarities between cases and can be strong or weak depending on the quality of the analogy. They are not inherently circular.

Option C:
Option C, probabilistic, describes reasoning that deals with degrees of likelihood rather than certainty, which is typical of inductive arguments but not necessarily flawed.

Option D:
Option D, deductive, names a broad class of arguments that aim for necessary support; some deductive arguments may be circular, but deduction as such is not defined by circularity.

Badhita hetu is one where the supposed universal connection between hetu and sadhya is refuted by more powerful means of knowledge. For example, an inference that fire is cold based on some spurious reason is contradicted by direct perceptual experience of fire's heat. In such cases, the hetu cannot be accepted as valid. Hence the fallacy described in the stem is badhita.

Option A:
Option A, savyabhicara, centres on irregular occurrence of the hetu with and without the sadhya, not on contradiction by other pramanas.

Option B:
Option B, satpratipaksha, involves competing reasons of equal strength on both sides of an issue, whereas badhita features clear overruling by a stronger source.

Option C:
Option C is correct because badhita means “defeated” or “overruled,” indicating that the alleged reason is nullified by superior evidence.

Option D:
Option D, asiddha, addresses the absence or non-establishment of the hetu in the paksha, which is a different flaw.
