The setting is the timeline and place that takes place in a story.

The theme is the lesson or moral a reader discovers that's found in the end of a story.

The plot is an entire set of ordered events that make up a story, such as exposition, rising action, climax, falling action,  and resolution.

The problem is the negative conflict, and it's also what triggers a set of events that take place to solve the conflict.

The main idea is main concept, or the central point of a story. It's the topic that gives the reader an 'idea' of what the story is about.

Explanation:

- "the basic difference between keywords and subjects is that subjects (or "subject headings") have been predetermined, while keywords have not. a keyword is an easy place to start because you can use any word that seems to fit your search; this is called "natural language" searching."
