Jawaban:

In an analytical exposition, a thesis refers to the main argument or central point that the author is trying to convey. The thesis usually appears in the introductory paragraph and serves as a roadmap for the rest of the essay. It is typically a clear, concise statement that outlines the author's perspective or opinion on a particular issue, and provides the main focus for the entire exposition.

The thesis should be supported throughout the essay with evidence, analysis, and reasoning to convince the reader of its validity. In summary, the thesis is a key element of an analytical exposition, as it provides the main idea or message that the author is trying to communicate.
