sheet of notes (both sides), handwritten and prepared

is worth 0 marks. There is therefore no penalty for
guessing on this exam.
If your answer is not included in the alternatives given,
mark the answer that is most nearly correct from those
alternatives.
If you need paper for rough work, use the back of the
sheets of this question paper. The question paper will be
collected at the end of the examination, but any writing
on it will not be read or marked.
This examination has 23 numbered pages; before you
start, check to see that you have all the pages. In ad-
