Which structural element drives the plot of a story?

The conflict drives the plot of a story. It is the central problem or struggle that the main character must face, and it propels the story forward as the character attempts to resolve or overcome it. Conflict can take many forms, such as man vs. man, man vs. nature, man vs. society, man vs. self, and man vs. supernatural forces. Ultimately, the resolution of the conflict determines the outcome of the story.
