General topics are usually the "discuss" ones.
Your interpretation can be as focused as you like, the more so the better, as general responses may result in superficial analysis, and you won't display the required depth of knowledge or insight. Best focus on key aspects of the prompt.
Eg. "The characters of X are lonely and sad. Discuss"
" X is a confused individual. Discuss"
In these examples the trigger words are obvious, but sometimes the VCAA will ask "How" or "why" questions which seem to offer no key trigger point
eg " How does X convey the tradegy of Y"
"Why does X falter"
The trigger words become the premise of the question. "How", becomes a essay on the story elements employed by the writer, and "why" becomes an examination of the underlying motives and external effects upon a character
As melanie.dee said, you really would want to explore subtlety to get that best marks, thought it may not be possible with topics such as these, therefore the complexity must come from your examples & evidence and therefore your exploration of them.
The key aspect of replying to general text prompts is too adopt a clear contention, sustained throughout the response. The only restriction is that it must be relevant.
The examiner will ask the following questions of any essay
Is it coherent?
Is it Sustained?
Is it substantiated?
Is it relevant?
Is it logically structured?
If you clearly address every question that can be asked of a response, the you can take a general topic question and shape it any way you want, and you should. Taking control of your response confidently and with flair clearly sets you apart from the rest of the pack.
