A student researching sleep has taken notes:
• Teens naturally shift to later sleep schedules • Early school start times conflict with teen biology • Sleep-deprived teens show decreased academic performance • Some districts have delayed start times with positive results • Logistics like bus schedules complicate policy changes
The student wants to argue for later school start times.
Sleep-deprived teenagers show decreased academic performance.
Schools should start later because teen biology naturally shifts to later sleep, early starts deprive them of rest and harm academics—and districts with later starts see positive results.
Teen bodies naturally shift toward later sleep schedules.
Logistics like bus schedules complicate changing school start times.
Correct Answer: B
Choice B. Biology, sleep deprivation harm, and positive results support the argument.
