Answer
Correct Answer: Only Conclusion I follows
Explanation
Introduction / Context:Classic syllogism: “All A are B”; “C is not B” ⇒ “C is not A.”
Given Data / Assumptions:
- All students in my class (set A) are intelligent (set B).
- Sunil ∉ B (not intelligent).
Concept / Approach:Contrapositive reasoning: If Sunil were a student in my class, he would be intelligent. He is not; therefore, he is not a student in my class.
Step-by-Step Solution:
• Conclusion I: Follows by contrapositive.• Conclusion II: “Must work hard” is a recommendation, not a logical necessity from the premises.Final Answer:Only Conclusion I follows.
