In informational text, what is the main idea, and what are the best kinds of details that support it?

• A. The main idea is the author's name; supporting details are page numbers
• B. The main idea is the central point the author wants you to understand; supporting details are facts, explanations, and examples that expand that point
• C. The main idea is the plot; supporting details are character names
• D. The main idea is a random statement; supporting details are irrelevant

Answer: (C)

In informational text, the main idea is the central point the author wants you to understand, and the best details are facts, explanations, and examples that expand that point. This framing fits because it shows how the author builds a clear message and uses concrete details to make that message stronger. The other options mix up what counts as the main idea or what kinds of details belong in informational writing: naming the author or page numbers aren’t the message itself, they’re just specific information; plot and character names belong to stories, not informational text; and calling the main idea a random statement with irrelevant details goes against the purpose of giving you a focused, evidence-based takeaway. So, the right idea is to identify the central point and then look for details that explain, illustrate, or prove that point.
