The thesis for your argument needs to be opinionated or debatable. The thesis will usually fall into 4 different categories or claims. You SHOULD make sure that your thesis fits one of the following types of claims. Sometimes, an arguable thesis may overlap and use 2 or even 3 different claims. Remember, the more claims you incorporate into your thesis, the longer your essay will be. Be sure that you construct a focused and narrow thesis-claim that will allow you enough room to write a full essay on your topic.
