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 learn about scientists who study teens sleep habits to understand the effects of her own internal clock to show the board why its better to start school later

Explanation:

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

• The first option focuses on encouraging early bedtimes, but the research on consequences is more likely to support a different goal (like school start time).
• The second option is about learning about scientists, which is not the main reason for researching consequences.
• The third option relates to her own internal clock, but the research on teens in general is broader than personal effects.
• The fourth option (to show the board why starting school later is better) aligns with researching sleep consequences to advocate for a later school start, as sleep deprivation in teens can be linked to early school times.

Answer:

D. to show the board why it's better to start school later (Note: Assuming the options are labeled A - D in order, with the last option being D. If the original labels were different, adjust the identifier but keep the text.)
