I believe it is a claim because it does focus on the main idea and what the text/passage should be about. If not I deeply apologize.
Students should have to have a certain amount of community service hours to graduate. For one, it would help the community, of course. Second, the students would learn about helping the community. And it would make graduating a little bit more of a challenge, so not just anyone can graduate. If doing community service was mandatory to graduate many people would benefit.
I am pretty sure it is "became". Hope that helped :)
I’m not sure exactly what you wish to talk about.. but lemme know if you need to talk. I understand things feeling pointless or that everything makes you miserable.
