Need help with getting thesis statement and paper in general

I wrote first few pages but worried not answering question with correct thesis and not comparing and contrasting its 5-7 page paper.
My Thesis: non idealized corpses like medical, museum candavers and criminal corpses provided more benefit to science than embalmed and prettied up idealized corpses in funeral homes. My prelim paper is due on Thursday.
I need thesis statement and then paper. I need draft today then original paper by tomorrow. I have attached few of my class reading handouts that you can get synopsis online.
