Part B. What is your thesis?
What statement's and evidence will you use to support your thesis?

Because I do not know anything about the prompt or what you are doing I cannot answer this question but what I can do is help you find the answer for yourself. Remember that a thesis is your side of a argument or what you think is right in a certain situation where they're two sides. You can provide statements and evidences by looking into the sources given to you and find the statements that help support why you think your side is correct in this situation.

Hope this helps.
