Answer: All you have to do is choose a poem or a short story and a historical document to read. Then you simply have to analyse both of them and compare them to each other. I would recommend you to choose both of this to talk about the same this. Just look for som that were from around the same time.
I think the dominant irony presented in the passage would be :
The Houyhnhnms. the most rational beings on earth, are discussing the extermination of an entire group of creatures.
You can see that in this sentence, the second part of the statement contradict the statement on the first part.
By the name "Revolutionary Tea", (even though i have never heard of the song), i can imply a few things.
1) It happened during the Revolutionary war
2) It has to do with Tea
Next, we will look at the answer choices. The only reasonable one is The Boston Tea Party, as while it is before the Revolution, it is the only one that had to do with Tea (dumping of tea over into the Boston Harbor from the ships), and led to the Revolutionary war.
The Boston Tea Party is your best answer
hope this helps
