joints, controlling weight, and preventing the development of high

Some studies suggest that physical activity may have other benefits
as well. One CDC study found that high school students who take part
in team sports or are physically active outside of school are less likely
to engage in risky behaviors, like using drugs or smoking. Physical
activity does not need to be strenuous to be beneficial. The CDC rec-
ommends moderate, daily physical activity for people of all ages, such
as brisk walking for 30 minutes or 15–20 minutes of more intense
exercise. A survey conducted by the National Association for Sport
and Physical Education questioned teens about their attitudes toward
exercise and about what it would take to get them moving. Teens
chose friends (56%) as their most likely motivators for becoming more
active, followed by parents (18%) and professional athletes (11%).- The first paragraph (lines 1–13) of the passage serves all of the
