How can you determine the main idea of a paragraph using topic sentence and details?

• A. Look at the font size.
• B. The best way is to find the sentence that clearly states the central idea and verify which details support it.
• C. Read only the first sentence.
• D. If the paragraph is long, the main idea is not present.

Answer: (B)

The main idea is the central point the paragraph is trying to convey, and you uncover it by looking for a sentence that clearly states that central idea and then checking which details support it. The sentence that expresses the main idea, often the topic sentence, guides how the rest of the details fit together. As you read, ask: do these details develop, illustrate, or prove that idea? If most of the details come back to that point, you’ve found the main idea. Remember that font size or reading only the first sentence won’t reveal it, and even long paragraphs can have a main idea that isn’t stated in a single early sentence. Sometimes the idea is implied, but you can still identify it by looking for the unifying purpose that the details back up.
