Choices 2.0: Situations for College Writing (Chapter 3) - Précis

In Chapter three of Joe Marshall Hardin's book, "Choices 2.0: Situations for College Writing", he claims that one must decide how to support a main idea, purpose, and thesis of a piece of writing in order to make a larger, more efficient impact on the reader.  Marshall supports his claims by explaining how one can gain credibility in ways such as self-experience and the experience of others and how they all tie in with ethos, logos, and pathos; along with taking a "problem approach" to make an argument that seems minimal become an argument that is actually worth bringing to light and creating an argument about.  The purpose of Marshall's writing is to inform and educate readers about the proper approach to writing a more credible and impactful piece of writing, in order to have a valid argument that will convince the reader to think of the writer's approach and thoughts; without the use of opinions or unrelateable experiences.  Clearly, the audience that Marshall is writing towards, are people, such as students, who should be informed of proper ways of making valid argumentative claims and the methods that make an argument more impactful.
