What strategies help ensure paragraph unity?

• A. Use a clear topic sentence, ensure all sentences support that idea, and remove off-topic material.
• B. Include unrelated sentences to show breadth.
• C. Start with a leading sentence that is unrelated.
• D. End with a different idea.

Answer: (A)

Paragraph unity comes from keeping the paragraph focused on one main idea. Start with a clear topic sentence that states that idea, then make sure every other sentence directly supports or develops it with evidence, details, or explanations. Trim any sentences or details that wander off topic so nothing pulls attention away from the central point. This keeps the paragraph a single coherent unit from beginning to end.

Unrelated or drifting sentences—whether introduced at the start, middle, or end—break that unity, which is why the other options don’t fit.
