Cause Essay: This essay explains the different causes and either presents your view or asks the reader to decide at the end. The introduction describes the effects and ends with the question: "What has caused...?" The body paragraphs describe one or more possible causes and the evidence for this. Generally, you will argue strongly for the most important cause in this type of essay. You may argue against some of the other reasonings. The conclusion either restates the cause you think is most important and argues for why the reader should believe it, or it asks the reader to decide.
