What term describes the arrangement of events or actions in the order they happen?

The term that accurately describes the arrangement of events or actions in the order they happen is sequence. Sequence emphasizes the specific order in which actions or events occur, often highlighting relationships and dependencies between them. This concept is fundamental in understanding how one event leads to another, which is essential in various fields including storytelling, history, and science.

While other terms may relate to the organization of events, they can carry different connotations. For instance, "chronological order" specifically refers to the timing of events, emphasizing their position in time, which is similar to but not synonymous with the broader concept of sequence. "Timeline structure" typically refers more to the visual representation of events along a timeline rather than the arrangement itself. "Event organization" is a general term that could refer to categorizing events without implying the actual order in which they occur.

Thus, "sequence" is the most precise term for describing the order of events as they unfold.
