Question

Which quote from chapter 23 of The Adventures of Huckleberry Finn contains sarcasm?

Answer 1

The correct answer here is the third option.

Sarcasm is when you say ridicule something or say something mockingly rudely and harshly. The third sentence is told by the duke on the raft after the duke and the king, with Huck and Jim in tow, escaped after tricking some townspeople who were going to throw vegetables at them. But they knew they were going to do that so they escaped and took all the money and did not even perform the third show. That's why this is sarcasm as he is mocking the townspeople saying they can use the vegetables and fruits to hit them fit and make a picnic.
