sleep is important for keeping your body healthy. sleep helps your brain clean toxins from the body. it also helps other parts of your body, like your muscles, rest so they can perform better.

Explanation:

The text focuses on the brain's activity during sleep, stating it keeps working to process information and help with decisions (like "sleep on it"). The first option summarizes this by highlighting the brain's sleep - time tasks (solving problems, remembering info, preparing for the next day).

Answer:

Your brain does a lot for you when you sleep. It can help you solve problems and remember new information. It also helps prepare you for a new day of tasks.
