5. | Statements: All men are dogs. All dogs are cats. Conclusions: I. All men are cats. II. All cats are men. |
A. | Only conclusion I follows | B. | Only conclusion II follows | C. | Either I or II follows | D. | Neither I nor II follows | E. | Both I and II follow | |
Answer: Option A
Explanation:
Since both the premises are universal and affirmative, the conclusion must be universal affirmative. However, conclusion II, being an A-type proposition, distributes the term 'cats'.
Since the term 'cats' is distributed in II without being distributed in any of the premises, so conclusion II cannot follow. Thus, only I follows.
