UGC NET Questions (Paper – 1)

Statements A, B and C correctly describe viruddha and bādhita as fallacious reasons, and E notes their exam relevance. D is false because viruddha hetu is defective, not ideal. Thus A, B, C and E only is correct.

Option A:
Option A is incomplete because it omits E.

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

Option C:
Option C is incorrect because it omits A (core definition of viruddha).

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

A truth functional connective is defined by the way it systematically turns combinations of truth values of component statements into a truth value for the whole. For such connectives, once the truth values of the parts are known, the truth of the compound is completely determined. Examples include conjunction, disjunction, conditional and biconditional as studied in truth tables. Thus the connective described in the stem is properly called truth functional.

Option A:
Option A, intensional, usually refers to expressions whose meaning involves more than just extension or truth value, such as belief operators, and so is not restricted to connectives determined purely by truth values. Intensional contexts often break straightforward truth-functionality. Therefore intensional is not the correct label here.

Option B:
Option B is correct because truth functional connectives behave exactly as the stem describes: their semantic contribution can be fully represented in a truth table. This makes them central to classical propositional logic.

Option C:
Option C, non truth functional, would describe connectives or operators whose effect cannot be captured solely by reference to the truth values of component statements, which is the opposite of what the question states.

Option D:
Option D, analogical, has to do with reasoning by analogy between cases rather than with how connectives determine truth values. It is unrelated to the technical notion of truth-functionality.

A, B and E are correct; C and D are wrong. Denying the antecedent and affirming the consequent are invalid forms; only modus ponens and modus tollens are valid. UGC NET tests spotting these invalid patterns.

Option A:
Option A is incorrect because D is also wrong; selecting only C is incomplete.

Option B:
Option B is incorrect because C is also wrong; selecting only D is incomplete.

Option C:
Option C is incorrect because B is correct (modus tollens), so including B as wrong is incorrect.

Option D:
Option D is correct because it identifies both invalid patterns (C and D) as wrong.

Statements A, B and C correctly identify the roles of major, minor and middle terms, and E is true about their use in solving exam questions. D is false because the major premise is defined as the premise containing the major term, not the minor term. Therefore, the correct collection of true statements is A, B, C and E only.

Option A:
Option A is incomplete since it omits E, not acknowledging the practical importance of term identification for applying rules like distribution and mood-figure checks. Without E, the answer does not reflect the exam-related aspect.

Option B:
Option B is incorrect because it includes D, which incorrectly defines the major premise by reference to the minor term. This misidentification would mislead students about syllogism structure.

Option C:
Option C is wrong as it leaves out A, omitting the statement that the major term is the predicate of the conclusion, which is central to understanding syllogistic form. Thus B, C and E only cannot be right.

Option D:
Option D is correct, gathering all true statements about the three terms and their exam relevance while excluding the false definition in D of the stem. It matches the standard explanation of terminology in categorical syllogism.

B, C, D and E are correct; A is false. Arthāpatti is explanatory postulation (e.g., Devadatta’s night-eating) and is treated as an independent pramāṇa by some Mīmāṃsā/Vedānta authors. UGC NET may test examples and school-acceptance. It is not accurately described as always having a directly perceived “middle term” in the pakṣa.

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

Option B:
Option B is incomplete because it omits C (core conceptual characterisation), which is true.

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 (false).

Only statement D is wrong; all the others correctly describe valid immediate inferences. It is true that E and I propositions are simply convertible and that obversion preserves logical equivalence for the standard forms. From “All S are P” we cannot with certainty derive “Some P are S”, and UGC NET questions frequently ask which of these inferences are valid. However, from “Some S are not P” we cannot infer “No S are P”, since the particular negative does not entail the universal negative, making D the sole incorrect statement.

Option A:
Option A is correct because it isolates D as the only false statement and leaves A, B, C and E untouched as valid logical claims. It accurately reflects standard rules for conversion and obversion and the limits of what can be inferred from an O-proposition. This matches both logic texts and exam-style reasoning.

Option B:
Option B is incorrect since it treats A as wrong along with D, even though A correctly states that the converse of an A-proposition does not follow with certainty. Including A among the wrong statements therefore misrepresents a genuine logical restriction.

Option C:
Option C is wrong because it adds C to the set of allegedly wrong statements. C is in fact correct, as obversion yields a logically equivalent proposition in all four standard forms, so C and D only misclassifies an important logical law.

Option D:
Option D is also incorrect since it groups B with D, thereby wrongly branding the simple convertibility of E and I propositions as incorrect. B and D only thus fails to respect the standard conversion rules that students must know for UGC NET.

Pratyaksha is the Nyaya term for perceptual knowledge obtained through immediate contact of the senses with their appropriate objects. It is regarded as a primary and direct means of knowledge, prior to inference and other mediate processes. Nyaya further analyses pratyaksha into ordinary and extraordinary forms depending on the manner of contact. Hence the kind of direct knowledge described in the stem is called pratyaksha.

Option A:
Option A, anumana, refers to inference as a means of knowledge where one moves from a perceived sign to an unperceived object through recognised concomitance. It is mediate, not direct, and so does not match the description of immediate sensory contact.

Option B:
Option B is correct because pratyaksha literally means perception and is defined in Nyaya as knowledge produced by the operation of sense organs on objects, free from defects and doubt. This aligns closely with the wording of the question.

Option C:
Option C, upamana, is knowledge gained by comparison or analogy, such as recognising an unknown animal by comparing it with a description of a known one. It is neither direct sensory contact nor simple inference.

Option D:
Option D, sabda, is verbal testimony, particularly from reliable or authoritative sources. It delivers knowledge through language rather than through direct perceptual contact with objects.

Statements A, B, C and D correctly describe how “unless” is handled in logical translation, while E is false. “p unless q” can be read as “if not q then p”, and this in turn is equivalent to “p or q”, often represented with “or” and negation in symbols. Mishandling this connective, such as turning it into “if p then q”, leads to incorrect formalisation in exam problems. Therefore, the correct set includes A, B, C and D only.

Option A:
Option A is incomplete because it omits D, not acknowledging the exam-specific warning that mistranslating “unless” leads to errors. A, B, C only therefore does not fully address the question’s focus on UGC NET practice.

Option B:
Option B is wrong since it leaves out A, losing the general point that “unless” is captured using “or” and negation in symbolic notation. B, C, D only therefore presents only a partial description.

Option C:
Option C is correct as it includes the definitional, equivalence and exam-oriented statements while excluding E, which mistakenly equates “unless” with a one-way conditional. This combination matches standard treatments in logic textbooks.

Option D:
Option D is incorrect because it omits B and thus fails to mention the key equivalence “if not q then p”, central to understanding “unless”. A, C, D only therefore cannot be the right answer.

Statements A, C, D and F are correct, while B and E are incorrect. Shading a region represents that it is empty, so “A and not B” shaded means there is no A outside B. An X marks the presence of at least one element, and three-circle diagrams handle arguments with up to three terms. When both premises are entered on the same diagram, it becomes clear whether the conclusion goes beyond the information given. B is wrong because shading does not indicate existence, and E is wrong because premises are not diagrammed separately when testing a syllogism. Thus A, C, D and F only is the correct set.

Option A:
Option A is incomplete because it omits F and therefore fails to mention the diagnostic role of Venn diagrams in spotting over-extended conclusions. Although A, C and D are correct, they do not cover the use of diagrams in checking whether conclusions follow. Hence A, C and D only cannot be accepted.

Option B:
Option B is incorrect because it includes E, which falsely states that each premise should be diagrammed separately. Proper practice is to combine the premises on a single diagram to see their joint implications. Including E makes the overall combination inconsistent with the standard method.

Option C:
Option C is wrong as it leaves out A and adds F to C and D only. While C, D and F are true, excluding A overlooks the meaning of shaded regions, an essential part of diagram interpretation. Therefore C, D and F only does not capture all the correct statements.

Option D:
Option D is correct since it brings together A, C, D and F, summarising both the representational rules and the inferential use of Venn diagrams. It rightly excludes B, which confuses shading with existence, and E, which misdescribes the testing procedure. This makes Option D the accurate answer.

A, B and E are correct; C and D are wrong. Standard notation uses “∧” for conjunction (and) and “∨” for disjunction (or), so C and D reverse meanings. Knowing symbols helps in UGC NET equivalence problems.

Option A:
Option A is incorrect because D is also wrong; selecting only C misses another error.

Option B:
Option B is incorrect because C is also wrong; selecting only D misses another error.

Option C:
Option C is incorrect because B is true (negation symbol), so including B as wrong is incorrect.

Option D:
Option D is correct because it identifies both reversed-symbol statements (C and D) as wrong.

Syadvada teaches that any statement about reality should be qualified by "syat", meaning "from a certain standpoint" or "in some respect". This doctrine reflects the belief that no single proposition can exhaustively capture the many-sided nature of things. By using such conditional language, Jainas aim to avoid dogmatism and logical conflict. Thus the doctrine of qualified assertion mentioned in the stem is syadvada.

Option A:
Option A, anekantavada, is the general metaphysical view of many-sided reality and serves as the philosophical basis for syadvada, but it does not explicitly prescribe the linguistic form of conditional statements.

Option B:
Option B, saptabhangi, is the sevenfold scheme of predications that operates within syadvada, not the overarching principle that every assertion should be qualified.

Option C:
Option C is correct because syadvada directly concerns how we should frame propositions about reality, insisting that each claim is true only relative to a particular standpoint or respect.

Option D:
Option D, pararthanumana, is inference for the sake of others and belongs to Nyaya discussions of argumentation rather than to Jaina doctrines of conditional speech.

Statements A, B, C and E correctly describe assumptions as unstated but necessary links that the author takes for granted, and highlight their role in reasoning questions. D is false because explicit facts in the passage are not assumptions; they are part of the given information. Therefore the true statements are A, B, C and E only.

Option A:
Option A is incomplete since it omits E, thereby ignoring the specific exam context where assumptions are usually implicit. Without E, the answer does not fully reflect how assumptions appear in UGC NET.

Option B:
Option B is correct as it gathers all the accurate conceptual points about what counts as an assumption and how it functions, while excluding D, which conflates given data with presuppositions. This set matches the guidelines used in assumption-type questions.

Option C:
Option C is incorrect because it leaves out B, failing to mention the key role of assumptions in bridging a logical gap between reason and conclusion. As such, it does not include all correct statements.

Option D:
Option D is wrong since it omits A and B, losing core defining features of assumptions. Therefore B, C and E only is incomplete.

Statements A, B and C properly describe the practice and usefulness of writing arguments in standard form, and E adds that we may include necessary implicit premises as assumptions. D is false because numbering and full symbolisation are not mandatory; they are helpful conventions. F is false since not every rhetorical or descriptive sentence functions as a premise. The correct combination is A, B, C and E only.

Option A:
Option A is incomplete because it omits E, the point about adding needed implicit premises.

Option B:
Option B is incorrect because it omits B and does not include all true statements.

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

Option D:
Option D is incorrect because it includes F and omits A.

Statements A, C, D and E correctly describe how assumptions and inferences work in exam passages, while B and F are false. Assumptions are often unstated but required for the statement to be reasonable, and inferences ask what goes beyond but follows from the text. Distinguishing these from mere restatement is key to critical thinking questions in UGC NET. B wrongly demands explicitness, and F wrongly claims that assumptions must be denied rather than presupposed by the author. Therefore A, C, D and E only is the correct combination.

Option A:
Option A is correct because it captures the role of assumptions as implicit supports and inferences as logical outcomes, along with their importance in exam settings. It excludes B and F, which misrepresent how assumptions are identified. This makes the option consistent with common reasoning pedagogy.

Option B:
Option B is incorrect as it includes B, demanding that assumptions be explicitly stated, which contradicts the usual definition of an assumption as something implicit. If everything were explicit, there would be no need to locate underlying assumptions at all. Hence the option is unsound.

Option C:
Option C is wrong because it omits A and includes F, keeping a mistaken view that assumptions must be denied while failing to define what an assumption is. Without A, learners lack a clear starting point for identifying assumptions. Including F further distorts the concept.

Option D:
Option D is incorrect since it includes F and omits D, thereby losing the emphasis on exam relevance and adding a false restriction on assumptions. This mixture fails to represent how such items are handled in UGC NET reasoning.

Nigamana is the concluding member of the Nyaya five-part inference in which the original thesis is reasserted as proved. It summarises the effect of hetu, drstanta and upanaya, affirming that the sadhya holds in the paksha. In this way it functions like the conclusion of a Western syllogism. Thus the restated and established thesis described in the stem is called nigamana.

Option A:
Option A, pratijna, is the initial assertion of the thesis before any support is provided. It introduces the claim rather than concluding it.

Option B:
Option B, hetu, supplies the reason or ground for the thesis but is not itself the final summarising statement.

Option C:
Option C, upanaya, applies the universal relation to the paksha, paving the way for the conclusion but not replacing it.

Option D:
Option D is correct because nigamana literally means “drawing together” and marks the completion of the inferential process with a confirmed statement.
