Here's why:
* Organization refers to the structure of a literary work. This includes things like:
* Plot: The sequence of events.
* Characters: The people (or other beings) in the story.
* Setting: The time and place of the story.
* Point of View: The perspective from which the story is told.
* Theme: The central idea or message.
* Central message/insight refers to the theme of a literary work. This is the underlying message or idea the author is trying to convey.
In short, the organization of a literary work is how the story is told, while the central message is what the story is about.
