 All of this work on examining your paper structure and how the argument is laid out and how sources function in your paper may lead you to rethink your thesis. This is a good thing to do at this stage. Sometimes in writing a paper, your thesis will shift without you realizing it. You'll end up answering a slightly different question to the one you initially posed. Or, you may simply realize that your thesis can be stated in a stronger form. In any case, after the work we've described, you should revisit your thesis and see if it matches the structure of your paper as you've revised it. This list of the qualities of a strong thesis may help you revise your thesis so that it's clear, is arguable, and matches the rest of your paper. It would be a good idea to shell your revised thesis to someone and ask them what they might expect a paper with this thesis to look like and what sorts of questions they would like to see answered.
