Question

Answer 1

Answer: 1. Key details support the central idea, while minor details are helpful but less important.

Explanation: Key details are the important facts or examples that directly back up the main idea or author’s message. Minor details are related and can add color or extra information, but they aren’t essential for understanding the central idea. The other choices are incorrect because minor details usually relate to the story (not “nothing to do”), key details aren’t the same as the central idea, and key details—rather than minor ones—primarily explain the author’s message.
