C. thesis statement
A thesis statement will overtly state the main point/argument of a paper. This is done by manner of creating an assertion that is usually based on your opinion and that is basically a one-sentence summary of your entire paper. For instance, “Violence on television dos not lead to violent behavior” is an opinionated statement that suggests the paper will contain arguments in support of how violent behavior is not caused by violence on television. Note that while it is okay for the thesis statement to be answering a question, it should never be a question since, after all, it is a thesis statement, not thesis question.
