Final answer:
Switching 'The Black Cat' to a third-person point of view, either limited or omniscient, would change the depth of insight into characters' thoughts and make the narrative less biased, with the omniscient viewpoint offering a comprehensive understanding of all characters and settings.
Step-by-step explanation:
If 'The Black Cat' were told from a third-person point of view instead of the first-person, there would be significant changes in how the story is presented. A third-person narrator could be limited or omniscient. A limited third-person narrator aligns with the perspective of one or several characters, only revealing their thoughts and emotions, thus providing a limited view of other characters in the story. This could mean the narrator provides a unbiased yet restricted account of events, potentially focusing more on the actions and dialogue of the main character. Alternatively, if the story used a third-person omniscient narrator, the narrator would have access to all characters’ thoughts and actions, making the story's perspective much broader. This would allow the reader to have a deeper understanding of the story's setting and background, as well as the internal states of all characters.
