Actually, people needed to be careful. If all the examiners wanted is your own regurgitated essay, they would have said simply write a personal response like the previous years.
However, given that this year they are being so hard and specific, they wanted to stop people regurgitating planned essays, so they made Quick the focus, so whislt it is okay to say Quick is insignificant, you would need to SAY WHY that was the case. Simply ignoring him, in effect would ignore the terms of the question. After all, "to what extent" in a question requires a personal judgement, but in doing so you need to provide reasons why or why not based on your knowledge.
This was a HARD exam, especially for Cloudstreet people where there are so many characters. I cannot believe how specific the Question was!
