Question

acknowledges that the “internal clock” of teens causes them to stay up and wake up later, so it recommends against teens starting school before 8:30 a.m. what is the main reason jilly researched the consequences of teens not getting enough sleep? to understand the effects of her own internal clock to learn about scientists who study teens sleep habits to encourage young people to go to bed earlier to show the board why its better to start school later

Explanation:

The context notes that teen internal clocks make them stay up/wake up late, with a recommendation against early school start times. Jilly's research on sleep deprivation consequences would logically support advocating for later school start times to a school board, matching this option. The other options do not align with the provided context about school start time recommendations.

Answer:

D. to show the board why it's better to start school later
