Statements: No tree is fruit. All fruits are sweet. Conclusions: I. No tree is sweet. II. Some sweet things are fruits
Correct answer: B. Only II
- A. Both
- B. Only II
- C. Only I
- D. None
Explanation
To solve this, examine the statements: 'No tree is fruit' and 'All fruits are sweet.' Conclusion I, 'No tree is sweet,' cannot be deduced because while trees are not fruits, the statements do not preclude trees from being sweet for other reasons. Conclusion II, 'Some sweet things are fruits,' is correct because all fruits, being sweet, naturally means some sweet things are fruits. Therefore, only conclusion II follows logically from the given statements.
