Cheating, huh?
Sorry, but you need to find out answers for yourself in life. This site is not for cheating on tests or quizzes or whatever. It's for getting help to questions, not for cheating. If you want to succeed in life, then you need to learn some things yourself and not always get the answers from someone else.
