UGC NET Questions (Paper – 1)

Statements A, B, C and E correctly describe different forms of hypothetical syllogisms, while D is false. A pure hypothetical syllogism chains conditionals, while mixed forms involve a conditional plus a categorical premise, as with modus ponens and modus tollens. Not every pattern with two conditionals and a categorical conclusion is valid; the form matters. UGC NET reasoning often includes such patterns, making E true. Thus A, B, C, E only is the correct set.

Option A:
Option A is incomplete because it omits E, ignoring the explicit exam focus of the question. A, B, C only therefore does not fully address the stem.

Option B:
Option B is wrong since it leaves out C, failing to mention that modus ponens and modus tollens are canonical examples of mixed hypothetical forms. A, B, E only thus under-describes the topic.

Option C:
Option C is correct as it gathers the main patterns and the exam orientation, while rightly excluding D, which overgeneralises about any argument combining two conditionals and one categorical conclusion.

Option D:
Option D is incorrect because it includes D, thereby endorsing the claim that any such structure is valid, which is demonstrably untrue. B, C, D, E only therefore mixes in a clear error.
