Question

What are 200 words to explain the importance of purpose,audience,tone,and content in academic writing?

Answer 1

I think the point is that YOU WRITE 200 WORDS (probably about 2 paragraphs) in which you address these elements of a piece of writing.

purpose = why are you writing this?
audience = for whom are you writing?
tone = what is your attitude toward your subject?
content = if you have nothing to say, don't bother writing; it'll end up being nonsense.
