You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.

- (A) If only conclusion I follows
- (B) If only conclusion II follows
- (C) If either I or II follows

Statements: All men are dogs. All dogs are cats.
Conclusions:
- All men are cats.
- All cats are men.
Answer: Option
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.
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.

Because "all cat are men" is not vice versa of "all men are cat", the vice versa will be "Some cats are men".
