mashhour-ga,

I suggest you focus your Question more specifically on the areas you
wish to know about. I assume you don't want an Answer that simply
lists, "A, C, D, E, A, B, B," etc. without any explanation. Explaining
each one of these 22 multiple choice questions is well beyond the
realm of a $15 Question for most researchers, not to mention the fact
that Google Answers does not do students' homework for them (see GA
Terms of Service).

I suggest narrowing down the specific topics you would like more
information on that will help you to understand your assignment, and
re-post the Question asking about those topics, for example, "I would
like to know more about the role glucose plays in diabetes, and how
that role figures into answering this multiple choice question.
