State the title of your paper in the form of a question. Your paper will offer alternative answers to this question. For example:
Do entangling alliances explain the outbreak of World War I?
Did interservice rivalry cause Japan to choose war in 1941?
Why did the United States leave the nuclear deal with Iran?
Why does Canada have so few icebreakers?
Open with a one paragraph summary of your argument and conclusion. You probably want to rewrite this after you finish your essay to make sure you are able to cash the check you write in your introduction.
Be explicit about the event, choices, or state of the world that you are trying to explain, i.e., your “dependent variable” (DV). The more specific you are about your topic, the more specific you can be with your explanations for why it is what it is.
