Topics to write about for a research Paper on The Crucible vs. McCarthyism?

I read the Crucible, and i had some knowledge of what happened during the McCarthyism era, but i have to write a 5 paragraph essay comparing the two and i dont know what each paragraph should be about. I know for the first and last are intro and conclusion but can some one give me topics that i can base the other three one. You dont have to give me info explaining them, just the topics. Thanks
