This document provides information on argumentation and the structure of argument essays. It defines argumentation as appealing to reason by connecting evidence in a logical chain to lead readers to an intended conclusion. There are four main types of arguments: definition, evaluation, cause-effect, and proposal. A good argument topic must be specific, controversial, researchable, rational, and relatable. An argument essay follows a basic structure with a claim, support/evidence, refutation of counter-arguments, and a conclusion that reinforces the claim. The introduction should grab the reader, provide background, and state the thesis. The body should present logical evidence and refute opposing views. The conclusion restates the key points and supports the thesis.
