A researcher studying the effects of sleep deprivation on college students finds that students who slept fewer than six hours the night before an exam scored, on average, twelve points lower than students who slept eight hours. What is the main idea of this passage?
The answer
Answer: B. The finding links fewer than six hours of sleep to scores twelve points lower, so the central claim is that sleep deprivation hurts academic performance. Nothing in the passage discusses exam timing, so rescheduling exams is an unsupported recommendation. The study compares six and eight hours but never says exactly eight is required for everyone. How often college students get enough sleep is never measured, so that option adds information the passage lacks.
