Statements: Some dogs are cats. All cats are lions. Conclusions: I. Some dogs are lions. II. Some lions are dogs. III. All dogs are lions.
Correct answer: A. I and II
- A. I and II
- B. Only II
- C. None follow
- D. Only III
Explanation
Given the statements 'Some dogs are cats' and 'All cats are lions,' we can logically deduce the following conclusions: 'Some dogs are lions' and 'Some lions are dogs.' This is because if some dogs are cats, and all cats are lions, then those dogs that are cats must also be lions. Therefore, conclusions I and II both follow logically. Conclusion III, 'All dogs are lions,' is incorrect because not all dogs are necessarily cats, and thus not all dogs can be lions.
