adolescentsyoungters who are passing their years of adolescense(though the word "adolescents" not incorrect, I have not seen it in common usage ) are supposed to doshould be made involved with it unpaid words in community(you already mentioned at the beggining that this is voluntary community work and that makes this part redundant) whichsince it would be a win-win situation for can bring huge benefits to both themselvesthe teenagers and community.

If you can come up with just one good reason and an example to support it, that's the best for you to earn marks during a limited time frame.
