In informational text, what helps build on the central idea by providing more information about it?

• A. Supporting evidence
• B. Rhyme
• C. Author bias
• D. Table of contents

Answer: (A)

Think about the central idea as the main point the author wants you to understand. What helps it grow is supporting evidence—facts, examples, statistics, definitions, and brief explanations that add information and show or prove how the idea works. These details deepen understanding and make the central idea feel more complete and convincing.

Rhyme is a poetic device and doesn’t typically deepen factual claims in informational text. Author bias refers to a perspective that can color information rather than add new details. A table of contents helps you find sections but doesn’t supply additional information about the idea itself.
