A problem-solution essay is an essay that describes a problem and discusses possible solutions to the problem. This type of essay may be assigned in a high school or college composition class, and it generally requires some research before the writing process can begin. The primary thrust of a problem-solution essay is usually either an argument for a specific solution to a problem, or a strong case for the urgent need to solve a problem. Like most essays, the problem-solution essay must contain an introduction, a thesis, a body, and a conclusion.
