Question

what is the main reason jilly researched the consequences of teens not getting enough sleep? to encourage young people to go to bed earlier to show the board why it’s better to start school later to understand the effects of her own internal clock to learn about scientists who study teens’ sleep habits

Explanation:

To determine the main reason Jilly researched teens' sleep consequences, we analyze each option:

• Option 1: Encouraging early bedtimes isn't directly tied to researching consequences of insufficient sleep.
• Option 2: If Jilly researched to show the board why starting school later is better, researching sleep consequences (like how lack of sleep affects teens) would support that argument (e.g., showing that later school start could help with sleep). This aligns with using research to advocate for a policy change.
• Option 3: Understanding her own internal clock is personal and not related to researching teens' sleep consequences.
• Option 4: Learning about scientists studying teens' sleep is about other researchers, not the reason for her own research on consequences.

Answer:

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