Final answer:
In "The Black Cat," the plot is driven by the narrator's madness and supernatural elements, which contribute to the macabre atmosphere and plot progression in the story.
Step-by-step explanation:
In Edgar Allan Poe's "The Black Cat," the plot is driven by a mixture of the narrator's madness and supernatural elements. The narrator's insanity is evident through his increasingly disturbing actions and thoughts, such as his compulsive and violent behaviors.
On the other hand, the presence of dark and malevolent forces is also depicted through the supernatural occurrences, like the appearance of an unsettling second black cat and the unexplainable hanging of the cat. Both factors contribute to the overall macabre atmosphere and plot progression in the story.
