What function do topic sentences perform within a paragraph?

• A. They serve as a conclusion
• B. They introduce the main idea of the paragraph
• C. They list all the supporting details
• D. They act as transitions between paragraphs

Answer: (B)

Topic sentences play a crucial role in guiding the reader through a paragraph by introducing its main idea. They set the stage for the information that follows and clearly communicate the central theme or point that will be discussed. This helps to create coherence and flow within the text, allowing readers to quickly grasp what the paragraph will cover. For instance, a strong topic sentence typically provides a summary of the supporting details that will be presented, making it easier for the reader to understand the connection between the main idea and the evidence or examples provided. By effectively establishing the main idea at the beginning of the paragraph, topic sentences enhance the overall clarity and structure of the writing.
