Answer:
2 has finished the poem that seemed too hard to write.
Step-by-step explanation:
Irony is a rhetorical device that presents a contrasting outcome from the expected. In other words, irony is when one thing is expected but the opposite happens.
In the given poem "Ode to an Otter", the speaker talks of being an otter, the desire to be free like the otter so that he can enjoy the summer days. And the last line's expression "I wouldn't have to think of what to write for my class poem" is ironic because he had already finished writing a poem. His dilemma in having to think to write a poem for schoolwork is solved before he realized it.
Thus, the correct answer is option 2.
