general questions on topics can best be addressed by careful study of the relevant material, both in your text and online. Broad essays on general topics aren't a productive use of tutors' time, so you probably won't get much help on such a request.

Once you get stuck on a particular item, state the question clearly so a correct answer can be provided.
