Okay, so there are actually 4 steps to write a theses statement.
#1 - State your topic. Your topic is the essential idea of your paper.......
#2 - State your main idea about this topic.......
#3 - Write three reasons that support your idea.........
#4 - Include an opposing viewpoint to your main idea if applicable........
I won't give the answers, but by reading this, I believe if you have to do these separate, the issue would more than likely be the topic, and then you would give the three reasons which would be in the "Claims" section. Remember you have to write (3) reasons. If you don't know what #4 means, it just means a point of view that is the opposite of, or contrary to, one's own viewpoint. For example, one person's point of view may be that no homework should be assigned in school. The opposing viewpoint would be that homework should be assigned in school.
Good luck! :P
If you still need help just let me know. :)
