PrepTest 80, Section 2, Question 23
Editorial: Teenagers tend to wake up around 8:00 A.M., the time when they stop releasing melatonin, and are sleepy if made to wake up earlier. Since sleepiness can impair driving ability, car accidents involving teenagers driving to school could be reduced if the school day began later than 8:00 A.M. Indeed, when the schedule for Granville's high school was changed so that school began at 8:30 A.M. rather than earlier, the overall number of car accidents involving teenage drivers in Granville declined.
