Identify the single scene in a story that changes the direction of the plot, and explain what would be different if that scene were removed.
A plot is not just a list of things that happen -- it is a chain where each link causes the next. Some scenes simply keep the story moving, but one scene usually does the real work: it flips the situation, reveals something hidden, or locks in an outcome that cannot be undone. Finding that scene is finding the engine of the whole plot.
A useful test is the "remove it" test: imagine cutting a scene out entirely. If the rest of the story would still make sense and end the same way, that scene was not doing critical plot work. If removing it would make the ending impossible or completely different, you have found the scene the whole plot depends on.
Mastery looks like: They can name the one scene a plot's outcome depends on and explain, using the "remove it" test, exactly what would change without it.
Common stumbles: Picking the most exciting or loudest scene (a chase, an argument) instead of the quieter scene that actually redirects the plot's outcome.
