What does a topic sentence typically convey?

A topic sentence typically conveys the main idea of the passage. It serves as a guiding statement that sets the stage for the content that follows. By presenting the central thought or argument of a paragraph, the topic sentence helps readers understand what the writer intends to communicate, making it easier for them to grasp the ensuing details and examples that support that main idea.

In contrast, a minor observation would not carry enough weight to represent the overarching theme of a paragraph. Similarly, a conclusion drawn from the text would typically come at the end rather than at the beginning, where a topic sentence would reside. Finally, while a question posed by the author can provoke thought or discussion, it does not assert a main idea in the way a topic sentence does. Thus, the primary function of a topic sentence is to articulate the main point of the passage clearly to the reader.
