When answering a essay question how long should be the answer be?

It all depends on the question. You should cover the whole question and if that means you need to write a page then write a page. Essay question length depends on the question if the question has about five parts to it then you should have about five paragraphs but no matter what you should at least write about three or more paragraphs on all essay questions if possible, cuz i understand that some question may not be able to write that many questions but you should have more then one paragraph.

I say about three or more, i've always done that and gotten good grades on my essays.
