What method helps determine the central idea when reading informational text?

• A. Summarizing the most important claim and supporting details
• B. Reading the bibliography
• C. Counting sentences
• D. Skipping the introduction

Answer: (A)

In informational text, the central idea is the main point the author wants you to take away about the topic, and it’s supported by specific facts or details. The method of summarizing the most important claim and the supporting details directly reveals that main point. By distilling the text to the core claim and the strongest evidence, you see how all the information fits together to explain or prove the idea. This approach focuses you on what the author is arguing, not just on isolated bits of information.

Other parts of a text don’t capture that main point as clearly. The bibliography lists sources used, which is useful for research but doesn’t tell you what the text is arguing. Counting sentences isn’t a reliable indicator of importance, since a crucial point can be stated in a single sentence or spread across many. Skipping the introduction can cause you to miss the stated purpose or thesis, which often signals the central idea.
