Question

Select the correct inference of the given passage from "The Cask of Amontillado." "The nitre!" I said; "see, it increases. It hangs like moss upon the vaults. We are below the river's bed. The drops of moisture trickle among the bones. Come, we will go back ere it is too late. Your cough--" "It is nothing," he said; "let us go on. (4 points)
The narrator is worried about the nitre on the walls of the vault.
The narrator knows it is already too late for Fortunato to escape.
Fortunato is worried about the moisture and bones in the vaults.
Fortunato wants to continue their descent into the vaults for the Amontillado.

Answer 1

The correct answer is the last ("Fortunato wants to continue their descent into the vaults for the Amontillado."). This is correct because the narrator has tempted Fortunato into retrieving the bottle of alcohol (which didn't really exist) so that Fortunato could be locked away, never to be seen again. 

Hope this helps!
