Question

Statement: A recent study found that students who sleep at least 7 hours a night tend to score higher on exams than those who sleep less. Conclusions: I. Adequate sleep may have a positive effect on exam performance. II. Students who sleep less than 7 hours always fail their exams.

• A. Only conclusion I follows
• B. Only conclusion II follows
• C. Both conclusions follow
• D. Neither conclusion follows

Hint:

Compare how strongly each conclusion is worded against how strongly the statement is worded - watch for absolute words that go beyond a simple tendency.

Answer 1

The Correct Option is A

The study links more sleep with higher scores, so conclusion I (adequate sleep may help performance) reasonably follows. Conclusion II is far too strong: 'always fail' is not supported, since the study only says such students tend to score lower, not that they fail. Only conclusion I follows. The correct option is 'Only conclusion I follows'.
