Which concept in classical plot theory emphasizes that all events should be connected toward a single purpose?

• A. Desis
• B. Lusis
• C. Climax
• D. Unity of Action

Answer: (D)

The idea being tested is that all events in a narrative should be connected toward one central purpose. Unity of Action is the term for this principle. It means every scene, conflict, and revelation must contribute to a single goal or resolution, so the plot stays focused and cohesive. The climax is simply the high point of that ongoing arc, not the rule itself, and other terms that describe moments of complication or turning points don’t capture the overall organizing idea. A clear example is a mystery where every clue and character action points toward solving the case; anything that drags in an unrelated subplot would break the unity of action.
