Which term refers to a story's main sequence of events?

The term that refers to a story's main sequence of events is narrative. A narrative encompasses the overall storyline, including the structure and the events that unfold from beginning to end. This can involve the characters' experiences, the setting, and how the story is conveyed through various devices, creating an engaging progression that leads to the story's resolution.

In contrast, the other terms have specific meanings that don’t capture the full essence of the story’s main events. For instance, "plot point" refers to specific instances in the plot where significant changes or developments occur, but it doesn't encompass the entire sequence of events. "Dialogue" pertains to the spoken exchanges between characters rather than the overarching storyline. "Conflict" describes the struggle or challenge faced by the characters, which is certainly an important aspect of narrative but not the main sequence of events itself. Thus, narrative is the most fitting term in this context.
