Essay Help! 1984 by George Orwell?

I have to write an essay about 1984 and I need help to build a strong thesis and a few topic sentences with quotes and evidence for me to expand on. The essay should be around 1500 words so I need maybe 5 or 6 paragraphs in the body. The essay question is, "Humanity needs to be controlled in order to function effectively. In your opinion is this the ultimate point of 1984?" If it helps, I think that it is an important point in the text, but not the 'ultimate point'. Thanks.
