Germany wanted to conquer countrues in both Europe and Asia. Thus I would it is C
President Wilson did not agree with the methods of the treaty, nor the conditions, therefore he did not sign the treaty.
I would say B. that is because when it says "whites" that refers to white colored skin people. Plus people back then would be called white because of there skin. Plus it was often "whites" that owned slaves!
Hope i helped!!!
