What is the difference between a topic sentence and a thesis statement, and how are they used in writing?

• A. A topic sentence introduces the paragraph's main idea; a thesis presents the overall argument and guides organization.
• B. A topic sentence and a thesis are synonyms.
• C. A topic sentence is always at the end of a paragraph.
• D. A thesis statement is only used in fiction.

Answer: (A)

The main idea here is how a topic sentence and a thesis statement function at different levels of writing. A topic sentence signals the specific idea a paragraph will develop and connects that paragraph to the part of the argument it supports. It sets the focus for that paragraph and shows how it relates to the larger discussion. A thesis statement, on the other hand, states the overall claim of the whole piece and outlines the main points you will cover to support that claim, guiding the organization of the entire essay. In practice, you establish a thesis early in the introduction, presenting the central argument you will defend. Then you craft topic sentences for each paragraph to introduce the particular point that backs up that argument, showing how each part contributes to the whole. So the best choice is that a topic sentence introduces the paragraph’s main idea, while a thesis presents the overall argument and guides the essay’s organization. The other options misstate the relationship or usage: they treat the two as synonyms, place a topic sentence at the end of a paragraph, or claim a thesis is only for fiction.
