Correct answer: A. Rest enhances academic performance
- A. Rest enhances academic performance
- B. Exams are hard
- C. Coffee boosts performance
- D. Teachers sleep too
Explanation
The correct inference from the statement 'Students who sleep 8 hours perform better' is that rest or adequate sleep enhances academic performance. This is because the statement directly links 8 hours of sleep to improved performance. Option A captures this causal relationship accurately. Option B is incorrect because it introduces an unrelated concept about exam difficulty, which is not addressed in the statement. Option C is incorrect as it introduces coffee, which is not mentioned. Option D is incorrect because it shifts focus to teachers, who are not part of the statement.
