I have discovered that in the Mock Exam for Signet this weekend, the relevant question was a) very popular and b) VERY poorly answered.
I have found the attached which should help. I didn't write ut and I don't know who did or how I came by it. They obviously put some workj into the diagrams so feel useful to publish. A brief read through however made me realise that some bits were in error- I have tried, quickly, to re-word to eliminate. I hope that it is now OK, but it certainly is so much better than the standard of the answers received that it is worth posting. If I subsequently find something escaped me, I'll amend.
