The introduction of your essay should describe the problem,event or issue as clearly as possible.Be straightforward.State your thesis clearly and concisely.Make sure that your thesis is appropriate for the guidelines of the assignment.Since the thesis statement drives the rest of the paper,it is important that it can be easily supported with facts.Thesis statements for expository or explanatory essays should not take a position or voice an opinion.
