UGC NET Questions (Paper – 1)

The argument’s form is: All A are B; All B are C; Therefore, All A are C. This is a standard valid syllogistic pattern; if the premises were true, the conclusion would necessarily follow. However, in reality the premises “All squares are circles” and “All circles are triangles” are false. Because at least one premise is false, the argument is not sound, even though its logical form is valid. Therefore, it is valid but unsound.

Option A:
Option A would require both validity and the truth of premises, which is not satisfied here because the premises distort geometric facts.

Option B:
Option B separates form and content, recognising that the inference pattern is correct while the factual premises render the argument unsound.

Option C:
Option C is impossible, because soundness presupposes validity; an invalid argument cannot be sound.

Option D:
Option D wrongly denies the validity of the form simply because the premises are false, confusing logical structure with factual accuracy.
