Which term refers to the outcome of an action in storytelling?

The term that refers to the outcome of an action in storytelling is "effect." In literature, the effect is the result or consequence of a particular action taken by a character or event that occurs within the narrative. It provides a critical understanding of how a storyline unfolds and the repercussions that actions have on characters and the plot. This term is essential in analyzing cause and effect relationships within a story, allowing readers to see how decisions and events shape the narrative's direction and the development of themes.

While the other terms may relate to storytelling in various ways, they do not specifically denote the outcome of an action. "Reveal" typically refers to the act of making something known or visible, "impact" can signify a strong influence or effect but does not exclusively point to the outcomes of actions, and "central idea" refers to the main point or theme of a text rather than the results of specific actions. Therefore, "effect" is the most accurate term in this context.
