Connection?
Background?
Illusion?
Narrative?

The term that describes a brief reference in a text to a fictional or historical story, person, or event that readers will be familiar with is called an "allusion." An allusion is a literary device used by writers to make a reference or mention something indirectly. It can be a reference to a well-known mythological character, historical figure, popular culture icon, or another literary work.

To determine the correct term, you can analyze the options provided:

1. Connection: While this term can be used more broadly, it does not specifically refer to a reference to a fictional or historical story, person, or event.

2. Background: This term generally refers to the context or circumstances in which something occurs, but it does not directly capture the idea of a reference to a fictional or historical story, person, or event either.

3. Illusion: This term refers to a false or misleading impression or perception, such as an optical illusion, and does not relate to a reference in a text.

4. Narrative: Although a narrative is a story or an account of events, it does not specifically capture the concept of a brief reference to a fictional or historical story, person, or event.

Therefore, the correct term you are looking for is "allusion."
