Essays / How to write a 3000-word essay about 'communication'? [4]

Thanks so much for all!
My professor wants us to do a presentation and then an essay related to it.
for my essay, actually I would write about sexualization in media(which is my presentation topic), but the problem is that, I have to talk in two views: liberal pluralism and marxism.

Uptil now, I am still trying to think hard about their views on sexualisation. Indeed, how could I make it to 3000 words?
