NOTE ON QUESTION 5
You should decide on possible conclusions based on the data given and your
knowledge of the techniques. Some conclusions will of course be better than
others, and so you must look at all possibilities and pick the most reasonable
possibility and discuss that one in your answer.
In the past, instead of interpreting the results given, some students started their answer with something
like: "...the results were caused by errors [or by impurities, or bad technique, or the phase of the moon,
etc.], and so therefore you should repeat...." The problem with this statement is that the results given do
not show any error, nor do the results show any contamination. When you are given data, you must
interpret what is there. You are not allowed to discard the results to invent your own, more convenient,
data.
