Answer:
The Israelites believed in only one God, as opposed to many gods.
Sulfur, boron, calcium and carbon
I would have to say A would probably be the best answer because the others are just a regular sentence telling them about the positive things about volunteering but A has a quote and to me that helps get people interested better.
The answer would be C.~! ^.^
The answer is A, because the protagonist is the main character, and that's what Rider is. The other answers don't really make sense in terms of the role he plays in the story.
Hope I helped!
