This pattern suggests that adolescent sleep duration on school nights is at least partly constrained by ______
When high schools shift their start times later in the morning, students often end up sleeping longer on school nights, even though many students also go to bed somewhat later than before the schedule change. Which choice most logically completes the text?
This pattern suggests that adolescent sleep duration on school nights is at least partly constrained by ______
This pattern suggests that adolescent sleep duration on school nights is at least partly constrained by ______
Answer and explanation
Answer: D: the time students must wake up for school, since a later start allows more total sleep even when bedtime shifts later too.
The detail that does the most work in the passage is that total sleep increased despite a later bedtime, which points to wake-up time, not bedtime, as the binding constraint being loosened. That's D. A, C, and B each introduce a factor the passage never discusses or measures.
