Question

read this excerpt from \the tell-tale heart\ by edgar allan poe.
his room was as black as pitch with the thick darkness, (for the shutters were close fastened, through fear of robbers,) and so i knew that he could not see the opening of the door, and i kept pushing it on steadily, steadily.
how does the situational irony of this excerpt affect \the tell-tale heart\?
it makes the old mans death feel more deserved since he was clearly causing the narrator great strife by worrying so much about the danger posed to him by robbers.
it shows that, despite what he says, the narrator was actually not very careful when he crept into the old mans room.
it shows that, while the narrator is unreliable, hes actually telling the truth about the problems and pain that the old man caused.

Explanation:

To determine the answer, analyze situational irony in "The Tell - Tale Heart". The old man fastens shutters for robbers, but the narrator (who kills him) uses this darkness to enter. The first option wrongly implies the old man “deserved” death, which goes against the story’s context (the narrator is insane, not justified). The third option is incorrect as the narrator is unreliable and the old man didn’t cause problems; the narrator’s motive is irrational. The second option is correct: the narrator claims to be careful, but the irony is that the old man’s fear of robbers (shutters closed) is what allows the narrator to enter, showing the narrator’s “carefulness” is ironic—he’s not as careful as he thinks, or the situation undermines his supposed caution (since the old man’s security measure for robbers aids the murderer).

Answer:

The second option (the one stating "It shows that, despite what he says, the narrator was actually not very careful when he crept into the old man's room.")
