Statements: Some birds can fly. No animal is bird. Conclusions: I. Some animals can fly. II. Birds are not animals
Correct answer: B. Only II
- A. Only I
- B. Only II
- C. Both
- D. None
Explanation
To solve this question, evaluate each conclusion separately based on the given statements. Statement 1 tells us that some birds can fly, while Statement 2 states that no animal is a bird. Conclusion I suggests that some animals can fly, but this conclusion cannot be drawn from the given statements because the statements do not link 'animals' to 'flying.' Conclusion II, however, follows logically because if no animal is a bird, it implies birds are not animals. Therefore, only Conclusion II is valid.
