Statements: Some Penguins are Peacocks. All Peacocks are Snakes. Which conclusion follows? 1: Some penguins are snakes. 2: No peacock is a penguin.
- Either 1 or 2 follows
- Only 2 follows
- Neither 1 nor 2 follows
- Only 1 follows
Show answer and solution
Correct answer: D. Only 1 follows
1. Some penguins are peacocks and all peacocks are snakes, so those penguins are snakes, meaning some penguins are snakes (1 follows).
2. Conclusion 2 contradicts the premise that some penguins are peacocks, so it cannot follow.
3. Hence only conclusion 1 follows.
