Question

Obesity rates may have risen since the 1970s because today,

students are more likely to walk or ride their bikes
families are more likely to cook their meals at home
restaurant portions are about 30 percent larger
students get more recess time at school

Answer 1

I'm like 97% sure it's the one about resturaut portions, If not my bad

Answer 2

C) Restaurant portions are about 30% larger.

Step-by-step explanation:

Answer A doesn't make sense, because if more people walked or rode their bike to school instead of taking the bus or a car, the obesity rates would be lower.

Answer B doesn't make sense, because if families cooked their meals at home instead of eating out or eating fast food, the obesity rates would be lower.

And, Finally. Answer D. Answer D doesn't make sense, because if students got more recess time at school, that would give them more time to run and play, as well as burning off calories.

Hope this helps! :)
