Answer: Central idea of the text
Step-by-step explanation:
A summary of an informational text includes the title and author, the central idea of the text, relevant key details, and a closing thought or statement.
The central idea of a text is the main point that the author is trying to make. It is the message that the author wants the reader to take away from the text. The central idea is often stated in the introduction of the text, but it may also be implied throughout the text.
