HURRY PLEASE!! In The Cask of Amontillado, which quotes are ironic and which are sincere?

“How long have you had that cough?”

“You are a man to be missed.”

“‘The Montresors,’ I replied, ‘were a great and numerous family.’”

“I will not impose upon your good nature.”

The vaults are insufferably damp.”

“And I to your long life.”
