Was this in a story or so?
If it is, I wouldnt know the answer to it but I will give you a guide.
Go back to the story while having the quote in the back of your mind.
The question is basically asking you why the oppostie happened. Ironic means "oppostite" or "different" from what is being said.
So basically find in the poem or story that something "bad" happened to him and thats your answer. For the rest of the questions, it's your opinion so either way it wont be a wrong answer :).
