UGC NET Questions (Paper – 1)

A set of statements is inconsistent if they cannot all be true at the same time. Saying “Some teachers are strict” asserts the existence of at least one strict teacher. Saying “No teacher is strict” denies that any teacher is strict. These two claims cannot both be true together; if one is true, the other must be false. Hence, this pair is logically inconsistent.

Option A:
Option A’s two statements are compatible, because if all poets are imaginative, then certainly some poets are imaginative, so both can be true together.

Option B:
Option B directly pits an existential claim against a universal negative about the same property, creating a clear contradiction.

Option C:
Option C is consistent because if all birds can fly and penguins are birds, it follows that penguins can fly within that system, even if this conflicts with real world facts.

Option D:
Option D is also consistent, allowing for a mixed group of scientists, some honest and some not, which poses no logical problem.
