Which quotation from this passage supports the viewpoint that adolescents are not getting enough
exercise?

"we are now eating 31 percent more calories than
we were forty years ago"

"the average American now eats fifteen more
pounds of sugar a year than in 1970"

"entertainment media, including TV, computers,
video games, cell phones and movies”

"only one-third of high school students get the
recommended levels of physical activity
acts,"

D. "Only one third of high school students get the recommended levels of physical activity."

Explanation:

Let's evaluate each answer choice.

"We are now eating 31 percent more calories than we were forty years ago."

This choice discusses calories, not exercise. Therefore, this cannot be the correct choice.

"The average American now eats fifteen more pounds of sugar a year than in 1970."

This choice pertains to sugar intake, not physical activity. This isn't the right choice.

"Entertainment media, including TV, computers, video games, cell phones, and movies."

This answer choice talks about screens and media, with no mention of exercise. Again, this cannot be correct.

"Only one third of high school students get the recommended levels of physical activity."

This choice must be correct. It mentions that teens, or high school students are not active enough.

So, choice D. "Only one third of high school students get the recommended levels of physical activity," is correct.
