UGC NET Questions (Paper – 1)

Statements A, C, D and F are correct, whereas B and E are incorrect. A standard categorical syllogism has three propositions involving exactly three distinct terms, and validity requires that the middle term be distributed at least once. Two negative premises cannot yield a valid conclusion because they fail to establish a positive link between the major and minor terms. Venn diagrams are widely used in reasoning questions to test such syllogisms visually. By contrast, B wrongly claims four terms, and E misstates the relationship between universal premises and the quantity of the conclusion. Therefore A, C, D and F only is the correct combination.

Option A:
Option A is incorrect because it omits F, leaving out the important fact that Venn diagrams are a recognised tool for checking validity. While A, C and D are true, the absence of F means this option does not contain all correct statements. Hence A, C and D only cannot be accepted.

Option B:
Option B is wrong since it includes E as though it were correct. E claims that universal premises always force a particular conclusion, but some valid moods, like Barbara, produce universal conclusions. Including this false rule makes the combination logically unsound.

Option C:
Option C is correct because it groups A, C, D and F, capturing the structural features and testing method of categorical syllogisms. It excludes B, which inflates the number of terms, and E, which oversimplifies the quality-quantity relations. Thus this option matches the genuine rules of classical syllogistic logic.

Option D:
Option D is incorrect because it accepts E as well as C, D and F while omitting A. Leaving out A ignores the three-proposition nature of syllogisms, and including E introduces a faulty generalisation about conclusions. Therefore C, D, E and F only cannot be the right answer.
