Debatable. A claim about which reasonable persons might dispute must be made in an argumentative thesis. Argumentative theses cannot be based on statements of truth or areas of widespread agreement because few individuals dispute on them. Rather, they are based on what some people believe or think about some subject. All arguments contain three basic components: a statement of a problem or issue, then a claim about the solution to the problem, and finally, a discussion of how well the claim solves the problem. In order for an argument to be deemed "debatable", there must be more than one way to solve the problem or issue at hand. If only one approach can be taken, then it cannot be debated since there is no reason to discuss other ways of solving the problem. For example, if I were to state that everyone should eat their vegetables as a way of preventing illness, this would not be a debatable idea as only one possible solution can be taken. However, if I were to argue that eating vegetables helps your body function better than by consuming harmful substances, then this would be a debatable claim as multiple solutions could be offered up for debate. Even though only one approach could be taken in the first example, it was still considered debatable since more than one solution could have been proposed for the problem at hand.
