A summary is a concise restatement of the main points of a piece of writing, usually much shorter than the original text. It includes the key idea and the main supporting details that contribute to that idea.
Here's how to break it down:
* Main idea: The central point or argument the writing is trying to convey.
* Supporting details: The evidence, examples, and explanations that support the main idea.
