Statements: No cat is a mouse. Some mice are animals. Conclusions: I. Some animals are cats. II. Some animals are mice. III. All animals are cats
Correct answer: A. Only II
- A. Only II
- B. I and II
- C. Only III
- D. None
Explanation
The correct answer is Only II. From the statement 'Some mice are animals,' it logically follows that 'Some animals are mice,' making conclusion II valid. Conclusion I, 'Some animals are cats,' is not supported because the statements do not provide any information connecting cats to animals. Conclusion III, 'All animals are cats,' is also not supported as there is no basis for such a universal claim in the provided statements. Therefore, the logical deduction that can be made based on the given statements is that 'Some animals are mice.'
