Statements: No flower is plastic. Some plastics are recyclable. Conclusions: I. Some recyclables are flowers. II. No recyclable is flower. III. Some plastics are not flowers
Correct answer: A. Only III
- A. Only III
- B. Only II
- C. none
- D. I and II
Explanation
To solve this logical deduction problem, we analyze each conclusion separately. Statement analysis gives us that 'No flower is plastic' and 'Some plastics are recyclable.' Therefore, conclusion III, 'Some plastics are not flowers,' is true because the plastic that is recyclable cannot be a flower. Conclusion I, 'Some recyclables are flowers,' is not supported because there's no direct link between recyclables and flowers. Conclusion II, 'No recyclable is flower,' is also not directly supported as we cannot definitively state the relationship between recyclables and flowers. Therefore, only conclusion III follows logically.
