Three statements are given, followed by three conclusions numbered I, II and III. Assuming the statements to be true, decide which of the conclusions logically follow(s). Statements: Some rats are mice. No mouse is a rodent. Some rats are kittens.

1. Only conclusion III follows
2. Only conclusion II follows
3. Neither conclusion follows
4. Only conclusion I follows

Correct answer: Only conclusion III follows

Solution

From the statements, some rats overlap with mice, and some rats overlap with kittens. Since no mouse is a rodent, any conclusion involving mice and rodents must be checked cautiously. The only conclusion that necessarily follows is conclusion III.
