What is a thesis statement?

A thesis statement serves as the backbone of an essay, providing a clear and concise summary of the main point or argument that the writer intends to convey. It typically appears at the end of the introductory paragraph, guiding the reader by outlining the central theme and direction of the essay. A well-crafted thesis statement not only states the main idea but also hints at the supporting points that will be discussed throughout the text, allowing for a cohesive and focused argument.

In contrast to other options, a lengthy description of the topic does not encapsulate the core argument and can lead to unnecessary verbosity. A question posed at the end of an essay does not assert a claim or viewpoint, which is crucial for a thesis. Lastly, a brief narrative about the subject may provide background but fails to express the analytical stance or claim that is essential in a thesis statement.
