What term describes the arrangement of a narrative's events?

The correct term that describes the arrangement of a narrative's events is structure. In literature, structure refers to the way in which the elements of a narrative are organized and presented to the reader. It involves the sequence and order of events, including how they unfold over time, the pacing of the story, and the relationships between different scenes or chapters. A well-structured narrative allows readers to follow the plot effectively and understand the development of characters and themes.

The terms 'dialogue,' 'sequence,' and 'layout' each pertain to different aspects of storytelling. Dialogue specifically refers to the spoken conversations between characters, while sequence refers to the order in which events occur, but it does not encompass the broader organizational framework that structure does. Layout generally relates to the physical or visual arrangement of text on a page rather than the narrative elements themselves. Thus, structure is the most appropriate choice to describe the overall arrangement of narrative events.
