Answer:
The sentence that best describes what the settings have in common is:
D. The settings of both stories move from open to confined spaces.
Step-by-step explanation:
We can find the answer to this question through an elimination process.
Letter A is incorrect. Is it only the story "The Cask of Amontillado" that happens in an European city during Carnival.
Letter B is also wrong. Since we know one of the stories takes place in Europe, and only there, it is not possible for both of them to be set in America.
Letter C is incorrect. The stories move from light to darkness, and not the opposite.
We are left with letter D, the correct option. Both stories have settings that move from open to confined spaces. In "The Cask of Amontillado", the characters are first out in the streets. Then, they move into the catacombs of Montresor's family. In "The Black Cat", the narrator was first a free man. The story moves from a house into a cellar. Finally, the narrator ends up in a prison cell. Therefore, both stories end up with their characters in more confined, dark spaces.
