Read the following passage and then answer the questions, below.
Many people wonder: Why do we sleep? Why do we dream? They ask.........
themselves the purpose, or reason. There are many theories, or opinions
about this , but scientists don’t know if these ideas are correct.
One theory of sleep says that during the day, we need to
sleep to make new chemicals and repair, or fix our bodies. This theory is
called the “ Repair Theory”. One piece of evidence for this theory is
that our bodies produce more of growth hormone while we sleep.
Another theory is that the purpose of sleep is to dream. Dreaming
occurs only during one stage , or period, of sleep ( Rapid Eye
movement- REM )sleep. REM sleep occurs about 90 minutes and last
for about 20 minutes. Some scientists believe that REM sleep helps us
............................to remember things, but others don’t believe and don’t agree.
