Make sure there is clarity to the "something alot deeper" because you dont want to write a piece where it all sounds like waffle. If they give you a bit of stimulus (like in some past HSC paper where they gave you the ripple with a quote for change) then use it in your essay. For that year, they expected students to use the quote given to answer the question and it said in their markers comments that there were a lack of students who did and lost marks. So if you can, integrate it as much as you can in your response
