Fast Friday 5 (wk4) Questions

These questions should be attempted without the use of reference material or search engines i.e. no cheating and looking up answers. If you do look up an answer because you are curious either leave out the answer or indicate that you did so.

My answer is final in all quizzes, however of you spot a problem in any question please mail me.
