Statements: No girl is rude. All rude are foolish. Conclusions: I. No girl is foolish. II. Some foolish are girls.
Correct answer: A. Only I
- A. Only I
- B. Only II
- C. Both
- D. None
Explanation
To solve this problem, let's analyze the statements: 'No girl is rude' and 'All rude are foolish'. From these, we can deduce that if no girl is rude, and all rude individuals are foolish, then no girl can be foolish. Therefore, Conclusion I ('No girl is foolish') logically follows. Conclusion II ('Some foolish are girls') contradicts the initial statement that 'No girl is rude', as it implies that some foolish individuals could be girls, which is not possible given the information. Hence, the correct answer is Option A: Only I.
