Question

the ______ is a lesson or moral in a story, often found in fictional texts. main text theme summary central idea

Explanation:

To solve this, we analyze each option:

• "main text" refers to the primary written content, not a lesson/moral.
• "theme" is defined as the underlying lesson, moral, or message (often about life/behavior) in a story, especially in fiction.
• "summary" is a concise retelling, not a lesson.
• "central idea" is the main point, but "theme" more specifically relates to a lesson/moral. So "theme" matches the description.

Answer:

B. theme
