Okay, so where did I say that I wanted a link to a site that has the answers? If you take the time to read the posts in this thread, you'll know that I asked for a link to a site that has information related to the questions on there. So far the links that have been posed are of no relevance to the q's.

As for you understanding the questions, they're made up by the examination body and although i'm greatful for the info you posted, do you have any links that I can visit and construct an answer for myself?
