2013 mock QB8

Hi All, 
I'd appreciate some feedback on this.

Hello,

To be fair, the methodology used to answer doesn't appear to answer the question and what is the purpose of pages two onward?

Part 1) asks for three mechanisms, the answer gives one.
Part 2) question not answered, nor does part 3.

In the exam, if there is a question your knowledge is weak on, don't answer it. Also, do what the question asks you. Give three examples means just that; they should also be distinct and ensure you can answer later parts of the question as often they form chain.

Hi Jerry, many thanks for the reply. 
Are you suggesting the three mechanisms listed are all the same?? 
I felt fairly comfortable answering this, but it appears I am way off the mark here. 
Does anyone have a model answer for this sort of question? 

Thanks
