UGC NET Questions (Paper – 1)

In logical reasoning, an argument is a connected group of statements in which one statement is presented as the conclusion. The remaining statements function as premises that support this conclusion. This structure of claim plus supporting reasons is exactly what the stem describes. Therefore the appropriate name for such a set of statements is an argument.

Option A:
Option A names argument, which is defined as premises offered in support of a conclusion. It captures both the inferential claim and the supporting reasons. Hence it precisely fits the description given in the question.

Option B:
Option B refers to an explanation, which clarifies why something happens or is the case. Explanations may use reasons, but they usually assume the truth of what is explained rather than argue for it. Thus explanation is not the general label for the structure mentioned in the stem.

Option C:
Option C, description, simply reports or depicts a situation without drawing an inferred claim. Descriptive sentences can all be true yet still fail to support a particular conclusion. Therefore a description does not match the idea of premises leading to a conclusion.

Option D:
Option D, illustration, presents examples to make a general claim clearer. Illustrations presuppose the claim instead of offering premises to justify it. Hence illustration alone does not constitute an argument in the logical sense required here.

Upamana is the pramana by which one comes to know something by recognising its similarity to a described, already known object. For example, after hearing that a gavaya is like a wild cow, one later identifies the gavaya by comparing it with cows one has seen. This process centrally involves grasping resemblance rather than direct perception or inference from a sign. Hence the comparative knowledge mentioned in the stem is called upamana.

Option A:
Option A, sabda, is testimony received from a reliable speaker or scripture. Although a description initiates the process of upamana, the decisive cognition of the new object occurs through comparison, not mere acceptance of words.

Option B:
Option B, smriti, is memory, which recalls past experiences but does not by itself introduce a new, previously unknown object through comparison. It is therefore not the pramana described.

Option C:
Option C, pratyaksha, is direct perception produced by sense-object contact. In the example of recognising a gavaya, the senses do perceive the animal, but the crucial knowledge that “this is that described animal” arises through comparison, which is upamana.

Option D:
Option D is correct because upamana highlights similarity as the operative factor in this new cognition. Indian logicians treat it as a distinct and important source of knowledge about unfamiliar entities.

Purvavat anumana proceeds from knowledge of a present cause to a future effect that has not yet occurred. Observing dark clouds and inferring impending rain illustrates this pattern. Nyaya classifies such reasoning as purvavat because the inferred event is temporally posterior to the observed basis. Hence the inference described in the stem is purvavat anumana.

Option A:
Option A is correct since purvavat literally means “from the prior” and is defined as inference from cause to effect. It fits the temporal direction exemplified by clouds predicting rain.

Option B:
Option B, sesavat, goes from effect to cause, such as inferring past rain from a flooded river, which reverses the direction of temporal inference.

Option C:
Option C, samanyatodrsta, involves inference based on general uniformities not strictly causal, such as inferring motion from changing position.

Option D:
Option D, kevalanvayi, is a classification based on the nature of vyapti, not on temporal ordering of cause and effect.

A valid categorical syllogism must contain exactly three terms: major, minor and middle. If ambiguous language or faulty structure introduces a fourth distinct term, the necessary linkage between major and minor via a single middle term is broken. This defect is known as the fallacy of four terms. Therefore the error described in the stem is correctly named four terms.

Option A:
Option A, undistributed middle, is a different fallacy where the middle term is not distributed in either premise, so it never refers to all members of its class. Although this also breaks the connection between major and minor terms, it does not involve adding an extra term.

Option B:
Option B is correct because the presence of four distinct terms means that the argument cannot be a proper syllogism, which by definition has only three. Often this happens due to equivocation, where a word is used with two different meanings.

Option C:
Option C, illicit major, occurs when the major term is distributed in the conclusion but not in the premise, which is a distribution error, not an increase in the number of terms.

Option D:
Option D, ambiguous conclusion, is not a standard named fallacy in traditional syllogistic logic, and ambiguity alone does not guarantee that exactly four terms are present.

Analogical reasoning draws a conclusion about one case by comparing it with another similar case. It emphasises shared relevant features to support the inference. The strength of the argument depends on the number and importance of these similarities. Therefore reasoning that relies on similarity between situations is aptly called analogical reasoning.

Option A:
Option A, deductive, does not primarily involve comparison of cases but derives conclusions from general premises. Deduction seeks necessary truth rather than similarity-based support. Thus deductive is not the label for similarity-based reasoning.

Option B:
Option B, causal, focuses on identifying cause–effect relations and may or may not involve comparison. While analogies can illustrate causal claims, causal reasoning is conceptually distinct. Hence causal is not the best description of the reasoning in the stem.

Option C:
Option C names analogical reasoning, which explicitly uses similarity between cases to justify a conclusion. It is common in legal reasoning, everyday arguments and scientific modelling. This makes analogical the correct answer here.

Option D:
Option D, mathematical, refers to reasoning with numbers, symbols and formal structures. Mathematical proofs are usually deductive rather than similarity-based. Therefore mathematical reasoning does not capture the comparative nature described in the question.

In propositional logic, the statement “if p, then q” is called a conditional or implication. It asserts that whenever p is true, q must also be true. This relation captures a directed dependence between antecedent and consequent. Therefore the connective in the stem is known as implication.

Option A:
Option A, biconditional, has the form “p if and only if q” and expresses a two-way equivalence. It is stronger than a simple conditional. Thus biconditional does not match the one-way “if p, then q” structure described here.

Option B:
Option B, disjunction, uses “or” to connect two statements and has different truth conditions. It does not encode a directional dependency from p to q. Hence disjunction cannot be the correct answer.

Option C:
Option C properly names implication as the connective that forms a conditional statement from an antecedent and a consequent. Its symbolisation as p → q corresponds exactly to “if p, then q”. Therefore implication is the best choice.

Option D:
Option D, conjunction, joins statements with “and” and requires both to be true. It lacks the conditional structure of premise leading to consequent. So conjunction is not the connective the question refers to.

Asiddha hetu is a defective reason that has not been successfully shown to exist in the paksha. Because the foundational fact is missing or doubtful, no valid inference can proceed from it. Nyaya further distinguishes subtypes depending on why the reason is unestablished. The core problem is that the middle term fails at the very starting point.

Option A:
Option A, badhita, indicates a reason whose vyapti is contradicted by a stronger pramana, not one that is simply absent or unproved in the subject. The hetu might be present but epistemically defeated.

Option B:
Option B, satpratipaksha, involves a reason that is counterbalanced by an equally strong opposing reason, which is different from lacking initial establishment.

Option C:
Option C, savyabhicara, deals with irregularity across instances, where the reason is present but not constantly linked with the sadhya, rather than being missing in the paksha itself.

Option D:
Option D is correct because asiddha literally means "unaccomplished" and precisely marks the failure of the hetu to be verified where it is claimed to occur. This prevents the inferential chain from getting off the ground.

Trairupya refers to the threefold set of criteria that any acceptable hetu must meet: it must occur in the paksha, be present wherever the sadhya is present and be absent where the sadhya is absent. Together, these conditions ensure that the proposed reason is reliably connected with the probandum. Nyaya uses trairupya as a rigorous test for evaluating potential middle terms.

Option A:
Option A, upadhi, is a limiting condition that reveals hidden restrictions on a supposed vyapti, but it is not itself the positive set of requirements for a valid hetu.

Option B:
Option B, vyapti, denotes the universal concomitance between hetu and sadhya but does not specify the distinct checks needed to see whether a particular hetu instance exemplifies that relation.

Option C:
Option C is correct because trairupya literally means "having three forms" and is explicitly formulated in Nyaya as the standard yardstick for judging the soundness of reasons in inference.

Option D:
Option D, hetvabhasa, refers to fallacious reasons that fail to meet one or more of these marks and is therefore a class of defects, not the criteria themselves.

A, B, D and E are correct; C is false. Cārvāka privileges perception, is sceptical about inference beyond direct experience, and is critical of Vedic ritual authority. It is covered in UGC NET Indian logic/epistemology.

Option A:
Option A is correct because it includes all true statements and excludes C, which wrongly attributes Vedic acceptance to Cārvāka.

Option B:
Option B is incomplete because it omits E (syllabus relevance), which is true.

Option C:
Option C is incomplete because it omits A (materialist identification), which is true.

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

Statements A, B, C and E are correct, while D is false. The Nyaya five-member syllogism lays out stages such as pratijñā, hetu and nigamana that correspond to compressed parts of Western arguments. The Western three-member form indeed has two premises and a conclusion, and pratijñā closely mirrors that conclusion. Nigamana is a restatement of the conclusion, so claiming it has no relation to the Western conclusion is wrong. UGC NET Indian logic questions often ask students to make this mapping, justifying E.

Option A:
Option A is incomplete because it omits C and therefore fails to mention the specific link between pratijñā and the Western conclusion. A, B, E only thus does not exhaust the correct information requested.

Option B:
Option B is also incomplete, leaving out A which states that Nyaya makes explicit steps that Western logic often leaves implicit. B, C, E only therefore does not give the full comparative picture.

Option C:
Option C still lacks B and therefore does not highlight the standard two-premise structure of the Western syllogism. A, C, E only is thus an inadequate set of correct statements.

Option D:
Option D is correct because it collects all and only the true statements about how Nyaya and Western syllogisms compare while excluding D, which wrongly disconnects nigamana from the idea of conclusion. This option aligns with both historical and exam-oriented discussions.

Statements A, C, D and E correctly capture the contrast between deductive and inductive reasoning, while B and F are false. Deductive arguments aim at certainty under true premises, and inductive arguments offer degrees of probability. Inductive generalisation moves from particular observations to broader claims, and even strong inductive conclusions remain open to revision. Analogical reasoning is typically classified as inductive because it infers from similarity in some respects to likely similarity in others. Hence the correct set of statements is A, C, D and E.

Option A:
Option A is incorrect because it omits E, ignoring the fact that analogical reasoning is usually treated as a type of inductive reasoning in exam contexts. While A, C and D are true, leaving out E makes the description of inductive forms incomplete. Therefore A, C and D only cannot represent the full set of correct statements.

Option B:
Option B is correct since it gathers A, C, D and E, all of which align with standard textbook distinctions between deductive and inductive reasoning. It excludes B, which wrongly suggests that adding premises can destroy deductive validity, and F, which wrongly claims that content-preserving transformations can always make induction deductive. This combination therefore accurately reflects accepted logical theory.

Option C:
Option C is wrong because it adds F to the otherwise correct trio C, D and E. F falsely suggests that every inductive argument can be turned into a deductively valid one without changing its content, which is not possible because inductive support is probabilistic, not necessary. Including F makes the option logically inconsistent.

Option D:
Option D is incorrect since it includes B along with A, C and D. B incorrectly asserts that adding a new premise can make a valid argument invalid, but validity is preserved when additional premises are simply conjoined. Therefore this combination, which accepts a false claim about validity, cannot be chosen as correct.

Statements D and E are wrong, while A, B, C and F are correct. A and B correctly describe the truth conditions for conjunction and inclusive disjunction, and C accurately symbolises the exclusive “either–or”. F is true because truth tables are standard tools for checking validity. D mistakenly describes a tautology instead of a contradiction, and E wrongly describes the condition for a contingent statement rather than a tautology, so these two are the wrong statements.

Option A:
Option A is incorrect because it singles out only D as wrong and ignores E, which also misrepresents the definition of a tautology. Since both D and E give inverted definitions, treating only one of them as wrong undercounts the errors. Therefore this option does not match the full set of wrong statements.

Option B:
Option B is also incomplete, as it selects only E and ignores D. D is clearly false because a contradiction is never true in any assignment, not always true. By failing to include D, this option again fails to capture all wrong statements listed.

Option C:
Option C is correct because it groups exactly D and E, the two statements that invert the standard meanings of contradiction and tautology. It leaves A, B, C and F untouched, all of which correctly describe truth-functional connectives and the use of truth tables. This combination therefore matches the required set of wrong statements.

Option D:
Option D is wrong because it adds B, which is a correct description of inclusive disjunction, to the set of wrong statements. B rightly states that “p or q” is false only when both p and q are false. Including B beside the genuinely wrong D and E makes the option logically inconsistent.

A, B, D and E are sound strategies; C is wrong because assuming something that contradicts given conditions makes the reasoning invalid and can only mislead. Therefore C alone is the wrong statement.

Option A:
Option A is correct because it singles out only C as incorrect and keeps the standard strategies intact.

Option B:
Option B is incorrect because it wrongly treats A as wrong; A is a standard elimination method.

Option C:
Option C is incorrect because it wrongly includes D as wrong; eliminating impossible options does improve chances in MCQs.

Option D:
Option D is incorrect because it wrongly treats B as wrong; combining clues is essential in such puzzles.

The post hoc fallacy is summarised by the phrase “after this, therefore because of this”. It mistakenly infers a causal relation merely from temporal succession. Just because one event comes after another does not mean the first caused the second. Hence the fallacy described in the stem is correctly called post hoc.

Option A:
Option A, straw man, involves misrepresenting an opponent’s position to make it easier to attack. It does not concern temporal order or causal assumptions. Therefore straw man is not the fallacy being described.

Option B:
Option B, ad hominem, attacks the character of a person instead of addressing the argument. This is a different kind of informal fallacy unrelated to event sequence. Thus ad hominem is not appropriate here.

Option C:
Option C correctly names the post hoc fallacy, which draws a causal conclusion solely from the fact that one event follows another. It warns against confusing correlation with causation. Therefore post hoc is the best answer.

Option D:
Option D, false analogy, bases a conclusion on an inappropriate or weak comparison between cases. While it is an informal fallacy, it does not rely on temporal succession. Hence false analogy cannot be the correct choice.

Upanaya explicitly connects the general vyapti illustrated in the drstanta with the paksha by stating that the reason found in the example is also present in the subject. It bridges universal and particular, preparing for the conclusion. This application confirms that the paksha falls under the general rule. Therefore the step described in the stem is called upanaya.

Option A:
Option A, nigamana, is the concluding step that restates the thesis as established and comes after the application has been made. It does not itself perform the application.

Option B:
Option B, drstanta, provides the example and statement of vyapti but does not yet relate it to the specific paksha. It sets the stage for upanaya.

Option C:
Option C is correct because upanaya literally means “leading towards” and refers to bringing the paksha under the scope of the vyapti. It is the crucial step that shows the rule is relevant to the particular case.

Option D:
Option D, pratijna, is the initial thesis and not the linking step between general rule and subject.
