Question

Read the paragraph about community service.

Answer 1

I would say that the controlling idea is the last one. 

Youths should prioritize community service in preparation for their future. 

I would say this since it seems as if it is commanding the youths to be more conscious about their community service.

Hope i helped ;D

Answer 2

As the whole paragrapgh develops, there is an emphasis on how important is for kids to involve themselves into community service and not only into academic activities. The author states that community service helps the student to confront real life and not only to achieve good grades. Therefore, the correct controlling idea that conveys this message is D: Youths should prioritize community service in preparation for their future.
