Final answer:
The thesis in a sitcom is generally presented at the beginning, but may be placed in the middle or at the end for dramatic effect or based on the audience's perspective.
Step-by-step explanation:
The location of the thesis, or statement of position, in a sitcom can vary depending on the writing style and intended effect. Typically, a thesis is presented at the beginning of a script, initiating the premise or conflict of the episode, followed by supporting evidence or narrative throughout the show. However, some scripts may present the thesis in the middle, after a buildup of compelling evidence, for a dramatic effect. Another approach is to reveal the thesis at the end of the episode, especially if it is anticipated that the audience may disagree with it. A persuasive script can follow a five-part argument structure, effectively placing the thesis and supporting arguments throughout the episode.
