Answer:
The answer is event.
Step-by-step explanation:
In a story, anything that happens to or is done by a character is called event. Events can change the direction of a story, the way characters are perceived by viewers or readers, the characters' being flat or complex... A story that has shallow events might be seen as boring. Events must be significant, otherwise the audience will see no reason to receive that information whatsoever and may even give up on the story for good.
