Hi there, the title says "urgent" but really this just looks like your homework. This forum is meant for students who are either applying to graduate school or are in graduate school to talk about their experiences and ask for advice. It is not meant for students to ask for help with their homework, or indeed try and get someone else to do their homework for them.
