UGC NET Questions (Paper – 1)

A is correct as a valid categorical syllogism uses exactly three distinct terms: major, minor and middle. B is true because the middle term must be distributed at least once to connect the extremes properly. C is correct since two negative premises provide no positive linkage, and D is true because two particular premises cannot logically support a universal conclusion. E is false because these are necessary but not sufficient conditions; a syllogism can meet them yet still be invalid for other reasons. Hence A, B, C and D only are correct.

Option A:
Option A omits D and thus fails to mention the important constraint on drawing universal conclusions from particular premises. While A, B and C are true, the omission of D makes the set incomplete.

Option B:
Option B ignores A, so it does not mention the three-term requirement; although B, C and D are true, this omission leaves out a central structural rule for syllogisms.

Option C:
Option C drops B and therefore fails to highlight the distribution requirement of the middle term, which is crucial for testing validity. Even with A, C and D present, missing B leaves the account incomplete.

Option D:
Option D is correct because it collects all the true structural rules while excluding E, which overstates their sufficiency. This matches how NET questions test necessary conditions for syllogistic validity.

Statements A, B, C, E and F are correct, while D is false. A states the three-term rule, and B correctly links negative premises to a negative conclusion. C expresses the rule that two particular premises yield no valid conclusion, and E notes the prohibition on illicitly distributing a term in the conclusion. Venn diagrams are indeed useful in UGC NET to visualise these constraints. D is wrong because many valid moods, such as Barbara, have two universal premises and a valid universal conclusion. Therefore A, B, C, E and F only is the correct combination.

Option A:
Option A is incomplete because it omits E and F, ignoring both the rule about illicit distribution and the exam technique for testing syllogisms. While A, B and C are correct, leaving out these two elements makes the account less complete. Hence A, B and C only cannot be accepted.

Option B:
Option B is also incomplete, since it includes E but omits F, failing to mention the practical Venn diagram method. Although A, B, C and E are true, they do not fully address how validity is tested in UGC NET contexts. Therefore A, B, C and E only is not the best answer.

Option C:
Option C is wrong because it omits A and includes only B, C, E and F. Without A, the crucial three-term rule is not mentioned, which is essential for understanding many fallacies. This omission prevents the option from reflecting all the true statements given.

Option D:
Option D is correct because it gathers A, B, C, E and F, giving a comprehensive summary of structural rules and testing methods, while excluding D, which incorrectly claims that universal premises cannot yield a valid conclusion. This option therefore matches established syllogistic theory.
