question 1 (1 point)
which section from the article best explains how sleep can affect memories?
question 1 options:
introduction [paragraphs 1-5]
"light sleep stages"
"no longer in control"
"flushing out harmful toxins"
question 2 (1 point)
read the following paragraph from the section "flushing out harmful toxins."
another theory is that sleep is restorative and cleans out harmful toxins that can hurt the brain. during sleep, the space between brain cells increases. this allows harmful toxic proteins to be flushed out. in an october 2013 issue of the journal science, researchers published the results of a study hypothesizing that the brain uses sleep to flush out harmful waste. this waste removal system, they suggest, is one of the major reasons why we sleep. by removing harmful waste from the brain, sleep may stave off diseases like alzheimer's, which is characterized by memory loss.
what conclusion is best supported by the paragraph above?
