All right, so when you are making an argument, you're going to construct an argument. One of the first things you have to do is you have to know the point that you're trying to make. As a part of making your point, you have to develop a thesis statement. A thesis statement is your claim or the point that you're trying to make. And preferably, it's condensed down to a very clear, concise and accurate statement, which we call a thesis statement, a statement that when someone here is that they know one. That's the promise you're making to your reader. And two, they know exactly the point you're trying to make. And there's no confusion. It's very clear and articulate. Once you've developed your thesis statement, you need to identify the evidence that you're going to use to support your thesis. Having evidence to do that is not optional. It's absolutely necessary, because, again, your thesis statement is a promise that you make. And the evidence that you use is how you keep that promise to your viewer, to your reader, to your audience.
