Which statement best describes the main idea of a paragraph?

• A. Typically, all of one paragraph's sentences relate to one main idea or point
• B. The paragraph should include unrelated ideas
• C. The paragraph is always narratively structured
• D. The paragraph must be at least five sentences

Answer: (A)

In a paragraph, unity means every sentence ties to one central point. The main idea is that central point the paragraph is making, which can be stated or implied, and all sentences work to explain, support, or develop it. When a paragraph stays focused, each sentence connects to that point and the message remains clear for the reader. Including unrelated ideas would break that unity and make the paragraph wander, making it harder to see what the paragraph is really trying to say. Not every paragraph is narrative; many are expository, descriptive, or persuasive, and they still revolve around one main idea. Paragraphs also vary in length, so there isn’t a required minimum like five sentences. Therefore, the best description is that typically all of a paragraph’s sentences relate to one main idea or point, which keeps the paragraph coherent and on topic.
