What type of volunteer work would be the most rewarding?

Explanation:

Prior knowledge is the knowledge that someone already has before they even meet any kind of new information. Someone's understanding of a text, for example, might be improved by using knowledge that he or she gathered before even reading the text.

Although some questions depend on learning new information to answer, knowing which work is most rewarding can be based only in prior knowledge. No new information is required to answer.
