Answer and Explanation:
The irony is presented in the poem as a situation that was not expected by the character of the poem, but that in a way the reader already imagined could happen. This is because the poem features a bell that was placed near a very dangerous rock near the sea. This bell was intended to serve as a warning so that sailors would not hit the rock and sink their boats.
However, a pirate, without any reason and only with the intention of harming the sailors, removed the bell from the rock and threw it into the sea.
The reader knew that the pirate would be punished in some way for this vile act, but the pirate did not expect punishment. The punishment he received was to hit his vessel on the rock and sink with it.
