UGC NET Questions (Paper – 1)

Pratyaksha is the Nyaya term for perceptual knowledge arising from appropriate contact of the senses with external objects. It is considered immediate and non-inferential, forming a basic foundation for other cognitions. Nyaya distinguishes ordinary and extraordinary kinds of such perception. Thus the direct sense-based knowledge described in the stem is called pratyaksha.

Option A:
Option A, anumana, is inference that moves from a perceived sign to an unperceived probandum through recognised concomitance. It is mediate and conceptual rather than immediate sensory contact. Hence it does not suit the description.

Option B:
Option B is correct because pratyaksha literally means perception and is defined in Nyaya as knowledge produced by sense-object contact free from defects and doubt. The stem clearly points to this direct sensory origin.

Option C:
Option C, upamana, is comparison-based knowledge where an unknown object is understood by likening it to a known one. It does not require direct contact with the object itself.

Option D:
Option D, sabda, refers to verbal testimony as a pramana, where knowledge comes from trustworthy words or scriptures rather than from the senses acting on objects.

Nirvikalpa pratyaksha is defined as an indeterminate awareness in which an object is grasped without being classified or verbally identified. At this level, the mind has not yet organised the content into a subject–predicate structure. Nyaya considers this stage as epistemically prior to determinate judgment. The description in the stem exactly matches this notion of nirvikalpa perception.

Option A:
Option A is correct because nirvikalpa literally means "without distinctions", indicating the absence of explicit conceptual differentiations such as universals or relations. It helps Nyaya explain how determinate knowledge can have a non-conceptual basis.

Option B:
Option B, savikalpa, is determinate perception that already involves recognition of universals and relations, which conflicts with the idea of perception without name or class.

Option C:
Option C, laukika, refers to ordinary empirical perception and cuts across the determinate–indeterminate distinction; it includes both nirvikalpa and savikalpa phases and hence is too broad.

Option D:
Option D, alaukika, designates extraordinary perception and does not specifically single out the indeterminate stage within perceptual cognition.

Logical form captures the structural pattern that arguments of many different topics can share. When content words are replaced by variables, what is left is the form that determines whether an argument is valid or invalid. This form is what logic studies in order to separate good reasoning from bad. Therefore the abstract pattern described in the stem is correctly called the logical form.

Option A:
Option A, content, refers to the specific subject matter or factual details discussed in the statements, not to the pattern they instantiate. Content can vary widely while the underlying reasoning pattern remains the same. Hence content is what we bracket off, not what we focus on, when we talk about form.

Option B:
Option B is correct because logical form is precisely the structure that different arguments can have in common despite discussing different topics. It is this form that allows us to say two arguments are of the same type and to classify them as valid or invalid purely on structural grounds.

Option C:
Option C, surface grammar, focuses on the linguistic arrangement of words such as word order and inflection, which may differ between languages without changing the underlying logical pattern. Thus surface grammar need not coincide with the logical structure relevant to validity.

Option D:
Option D, rhetoric, is concerned with persuasive style and techniques aimed at influencing an audience. Rhetorical devices may affect how arguments are received but do not by themselves determine the underlying pattern of inference.

A sound argument satisfies two conditions: it is deductively valid and all of its premises are in fact true. When these conditions hold, the conclusion must not only follow logically but must also be true. Soundness thus combines the formal virtue of validity with the material virtue of factual correctness. Therefore the argument described in the stem is properly called sound.

Option A:
Option A, strong, is used to evaluate inductive arguments where premises make the conclusion highly probable, not deductively certain. It does not by itself guarantee truth or validity in the deductive sense.

Option B:
Option B is correct because soundness is the recognised standard for high-quality deductive arguments whose conclusions we can safely accept as true. The stem explicitly mentions both validity and true premises, which are the defining features of a sound argument.

Option C:
Option C, cogent, is the analogous term for inductive arguments that are strong and have true premises, leading to a probably true conclusion. It does not apply to deductive arguments characterised by necessity.

Option D:
Option D, circular, denotes a pattern of reasoning in which the conclusion is effectively assumed in the premises. Such arguments are logically flawed even if the premises and conclusion are all true and so cannot serve as the ideal described in the question.

Samanyalaksana pratyaksha is an extraordinary perception in which universals are directly presented through their instances. By observing many individual cows, one comes to perceive the common nature that unites them, namely cowness. Nyaya treats this as a distinct kind of perception that allows abstract classification. Therefore the type of perception in the stem is called samanyalaksana pratyaksha.

Option A:
Option A is correct because samanyalaksana literally refers to the mark of generality, indicating that the focus is on grasping what is common across cases. It explains how we can have cognitive access to universals, not just to particular objects.

Option B:
Option B, jnanalaksana, concerns perception mediated by the trace of a previous cognition and typically explains cross-modal awareness, not the direct apprehension of universals through many instances.

Option C:
Option C, yogaja, is yogic perception arising from intense meditative practice and is not limited to universals in the way described.

Option D:
Option D, laukika, refers to ordinary sense perception and does not specify the special presentation of universals that characterises samanyalaksana.

Nirvikalpa pratyaksha is characterised as a bare awareness of an object without recognition of its name, class or properties. It is prior to judgment and conceptual articulation. Nyaya holds that such a stage precedes determinate cognition in the perceptual process. Therefore the indeterminate perception mentioned in the stem is nirvikalpa pratyaksha.

Option A:
Option A is correct because nirvikalpa literally means “without differentiation,” capturing the non-conceptual nature of this awareness. It is a subtle epistemic stage discussed by Indian logicians.

Option B:
Option B, savikalpa, is determinate perception that includes classification and predication, such as “this is a cow.” It does not fit the content of being free from relational details.

Option C:
Option C, laukika, refers to ordinary perception via external senses and can be either determinate or indeterminate; it is not defined specifically by the absence of conceptualisation.

Option D:
Option D, alaukika, denotes extraordinary perception beyond normal sense contact, such as yogic or universal perception, which is a different distinction from determinate versus indeterminate.

A, B and C correctly describe variations in pramāṇa lists across schools, and E reflects a common exam question pattern. D is false because Cārvāka is generally sceptical and does not accept Nyaya’s full set, rejecting scriptural authority. Thus A, B, C and E only are correct.

Option A:
Option A is correct because it includes all true statements and excludes D (false about Cārvāka).

Option B:
Option B is incomplete because it omits E (exam pattern).

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

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

Asambhava refers to a definitional defect in which the specified characteristics cannot be jointly realised by any object. The definition sets up an impossible or contradictory condition, ensuring that the definiendum has an empty extension. Such a definition fails worst of all because it does not even capture the genuine instances it was designed for. Therefore the impossibility described in the stem is called asambhava.

Option A:
Option A, avyapti, concerns definitions that are too narrow but still have some real instances; it does not entail outright impossibility.

Option B:
Option B is correct because asambhava literally means "non-existence" and is used in logical discussion to highlight definitions that cannot possibly be satisfied. It underscores the importance of internal coherence in conceptual analysis.

Option C:
Option C, ativyapti, denotes over-definition where too many objects fall under the definition, which contrasts with the empty extension produced by asambhava.

Option D:
Option D, upadhi, is a limiting condition in the context of vyapti, not a label for defects in the structure of definitions.

A universal negative proposition denies that any member of the subject class belongs to the predicate class. Its standard form is "No S are P", and in the traditional scheme it is labelled as an E-type proposition. This combination of universal scope and negative quality fits the description in the stem. Hence it is called a universal negative proposition.

Option A:
Option A, particular negative, is limited in scope to some members of the subject class, as in "Some S are not P". It does not deny membership for all subjects and so cannot represent the form given in the question.

Option B:
Option B is correct because universal negative precisely designates a statement that denies the predicate of every member of the subject class. It is a key category in the square of opposition and contrasts with universal affirmative statements. This alignment makes universal negative the appropriate choice.

Option C:
Option C, universal affirmative, asserts that all members of the subject class belong to the predicate class. It has the opposite quality to the negative proposition described and therefore does not match.

Option D:
Option D, particular affirmative, affirms the predicate for at least one member of the subject class. It is both narrower in scope and positive in quality, which differs from the universal denial described in the stem.

A valid argument is one in which it is impossible for the premises to be true and the conclusion false. This captures the idea that the conclusion follows necessarily from the premises. Validity concerns the logical form of the argument, not the actual truth of its statements. Therefore the argument described in the stem is correctly called valid.

Option A:
Option A names valid argument, which is defined by necessary truth preservation from premises to conclusion. It exactly fits the description that the conclusion must follow from the premises. Hence this option is the correct label.

Option B:
Option B, sound, additionally requires that a valid argument have all true premises. Soundness is a stronger property than validity. Since the stem mentions only necessary following, not truth of premises, sound is not the best match.

Option C:
Option C, weak, usually describes an inductive argument in which the premises provide little support for the conclusion. Weak arguments do not ensure or strongly suggest the truth of the conclusion. Thus weak is opposite to the idea expressed in the question.

Option D:
Option D, persuasive, indicates that an argument is psychologically convincing, which may occur even if it is logically bad. Persuasion depends on audience factors rather than strict logical consequence. Therefore persuasive is not the technical term required here.

Venn diagrams use overlapping regions, typically circles, to show how different classes or sets relate to one another. By shading or marking areas of these diagrams according to the premises, one can visually check whether a proposed conclusion is forced. This method is standard in examining the validity of categorical syllogisms. Therefore the diagrams described in the stem are called Venn diagrams.

Option A:
Option A, flow charts, represent sequential steps, decisions and processes, often in computer science or management contexts. They are not designed to depict class inclusion and exclusion in the way needed for syllogistic reasoning.

Option B:
Option B, decision trees, model branching choices and outcomes, particularly in decision analysis and probability. While they can involve logical structure, they do not primarily illustrate class relationships among terms.

Option C:
Option C is correct because Venn diagrams were specifically developed to handle set-theoretic relationships, which align neatly with categorical propositions. Their overlapping circles allow us to see intersections, unions and complements, making them ideal for testing syllogisms.

Option D:
Option D, matrices, can organise numerical or logical information, but they are not the conventional visual tool for representing class inclusion patterns in introductory logic.

All six statements together give a coherent picture of fallacious and valid reasons in Indian logic, so A, B, C, D, E and F are correct. Hetvābhāsa is indeed an apparently sound but defective reason, and asiddha and viruddha are classic examples where the reason is unestablished or proves the opposite. Satpratipakṣa and bādhita identify reasons neutralised or overridden by equally strong or stronger knowledge. The final statement summarises the threefold condition for a valid hetu: presence in the pakṣa, presence in sapakṣa and absence in vipakṣa. Hence every statement listed is accurate, making this the correct combination.

Option A:
Option A is incorrect because it stops at A, B, C and D, leaving out E and F, which also state correct and important aspects of Indian inference theory. Without bādhita hetu and the positive conditions of a valid hetu, the account of reasons and fallacies is incomplete. Therefore A, B, C and D only cannot be accepted as correct.

Option B:
Option B is still incomplete since it omits F, the summary condition for a valid hetu, even though it adds E. While E is correct about contradiction by stronger pramāṇa, leaving out F fails to mention the standard threefold test for a proper reason. Thus A, B, C, D and E only does not capture the full set of true statements.

Option C:
Option C is correct because it includes all six accurate statements that together describe types of hetvābhāsa and the structural requirements of a valid hetu. There is no falsehood among A–F, so the only way to select all correct statements is to choose the option listing all of them. This makes Option C the right answer by matching the full, correct set.

Option D:
Option D is wrong because it leaves out A, which defines hetvābhāsa itself, and thus ignores the overarching concept under which the listed fallacies are grouped. Even though B, C, D, E and F are true, omitting A means the combination is not the complete set of correct statements in the question.

The fallacy of undistributed middle occurs when the middle term in a syllogism is never taken to refer to all members of its class in any premise. As a result, the premises fail to establish a necessary connection between the major and minor terms. Without a properly distributed middle, the conclusion does not logically follow. Thus the situation described in the stem is the fallacy of undistributed middle.

Option A:
Option A is correct because the defining error is precisely that the middle term is left undistributed in both premises. This allows the argument to illegitimately treat partially overlapping sets as if they were fully connected. Recognising this flaw is essential to testing categorical syllogisms.

Option B:
Option B, illicit major, arises when the major term is undistributed in the premise but distributed in the conclusion, which is a different kind of distribution error. While serious, it is not the same problem as the middle term never being distributed.

Option C:
Option C, illicit minor, similarly involves the minor term being distributed in the conclusion without being distributed in the minor premise. Again, this concerns a different term than the one described in the stem.

Option D:
Option D, four terms, describes a fallacy where a syllogism effectively involves more than three distinct terms, often due to ambiguity. It does not depend on the distribution status of the middle term in the way indicated in the question.

Statements A, B, C and E correctly describe validity and soundness, while D is clearly false. Validity concerns the relationship between premises and conclusion such that true premises cannot yield a false conclusion, and soundness adds the factual truth of premises. A valid argument may still have false premises, so C is also correct. Sound arguments must have true conclusions, not false ones, hence D is rejected, and all the true statements together are captured by option B.

Option A:
Option A is incorrect because it omits E, ignoring the explicit relevance of distinguishing validity and truth in UGC NET reasoning questions. Although A, B and C are true, leaving out E means the set is incomplete. This combination does not fully answer the question as stated.

Option B:
Option B is correct since it includes exactly the true statements A, B, C and E and excludes D, which wrongly claims that sound arguments must end in false conclusions. This option therefore matches standard textbook definitions and exam practice. It recognises that soundness guarantees a true conclusion, the opposite of what D asserts.

Option C:
Option C is wrong because it leaves out A, the central definition of validity, and thus fails to include all the correct statements. Even though B, C and E are true, missing A makes the combination partially accurate only. Hence it cannot be the right answer.

Option D:
Option D is incorrect because it omits B, the definition of soundness, which is essential in this context, and still includes only part of the true set. A, C, E only therefore fails to capture the complete group of correct statements required by the question.

A, B and C correctly describe circular reasoning and how it may be disguised, and E is true about its appearance in exam passages. D is false: sharing a topic does not make an argument circular; circularity requires assuming the conclusion. 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 overgeneralisation).

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 (core definition).

Option D:
Option D is incorrect because it includes D (false) and omits B (lack of independent support).
