Question

characters with strong feelings.
historical material.
a narrator.
dialogue.

Explanation:

To ground a fictionalized story in real events, the core requirement is tying it to factual, real-world context. Historical material provides the authentic, event-based foundation that links the fictional elements to actual occurrences. The other options (strong-feeling characters, a narrator, dialogue) are common in all fictional works, not specifically those based on real events.

historical material.
