Answer:
1 and 3
Step-by-step explanation:
1. The keyword is immolation, which means: "kill or offer as a sacrifice, especially by burning." While the narrator does not kill Fortunato by burning him, he is killed as revenge - which leads to 3
3. The keyword here is avenged - i.e. Montressor will be avenged by killing Fortunato, who had previously insulted him.
You could also argue that 4 is another, since Montressor knows his staff won't actually stay, but I'm not sure if that's what they're looking for.
P.S. if this was helpful - please let me know!
