What is the function of the topic sentence in a paragraph about digital literacy in classrooms?

• A. It provides concrete data
• B. It states the paragraph’s main idea
• C. It introduces a counterargument
• D. It gives a concluding remark

Answer: (B)

The main idea of the paragraph is signaled by the topic sentence. In a discussion about digital literacy in classrooms, the topic sentence states the central claim the paragraph will develop—what digital literacy means in that setting, why it matters, or how it affects teaching and learning. The rest of the sentences then supply reasons, examples, or analysis that support that central point, creating coherence as they circle back to the main idea. Placing the idea early helps readers know what to expect and keeps the paragraph focused. Data, counterarguments, or concluding remarks serve different roles: data provides evidence, counterarguments appear in persuasive writing, and a concluding sentence wraps up. So the function is to state the paragraph’s main idea and set up the details that follow.
