read the following title and subheading.
title: nutrition and you
subheading: why you need protein
what might be the main idea of a paragraph under this title and subheading?
some sources of protein are meat, fish, eggs, beans, and dairy products.

it is important to eat calcium to have strong bones.
eating sugary foods gives you an energy rush - but doesnt provide any nutrition for your body.

Explanation:

The title is "Nutrition and You" and the subheading is "Why You Need Protein". The main idea of a paragraph under this should be related to the necessity of protein. The first option lists protein sources (not why needed). The third option is about calcium. The fourth option is about sugary foods. Only the second option, "Protein is necessary for keeping your body healthy", directly addresses why protein is needed (relates to the subheading).

Answer:

Protein is necessary for keeping your body healthy.
