UGC NET Questions (Paper – 1)

Statement A shows a valid chain of universals, so “All poets are creative” follows. C is valid because “No cats are dogs” is equivalent to “No dogs are cats”. E is correct provided at least one engineer exists; then at least one graduate is an engineer. B and D are invalid because they overgeneralise from particular statements. Thus A, C and E only are correct.

Option A:
Option A is incomplete because it omits E, missing the (existence-assumed) inference from “All engineers are graduates” to “Some graduates are engineers”.

Option B:
Option B is wrong because it introduces D, which wrongly generalises from “Some students are not diligent” to “No students are diligent”.

Option C:
Option C is correct because it collects exactly the valid inferences and excludes B and D, which are invalid generalisations.

Option D:
Option D is incorrect because it accepts B, which misreads a particular statement as a universal, and so includes an invalid inference.
