Answer:
The duke knows how to get what he wants.
The duke shows signs of intelligence.
The duke is intentionally trying to trick the townspeople.
Explanation:
Mark Twain's "The Adventures of Huckleberry Finn" revolves around the story of Huck Finn, a young orphaned boy, and his desire to go on an adventure. The story follows the runaway boy and an escaped slave, Jim's adventures along the banks of the Mississippi River.
The duke is a character that Huck and Jim encountered. The duke and his partner the dauphin are a duo of 'cheaters' who would always commit fraud for their own gain. And in the given dialogue of the duke, we can know that he is intelligent, knows what he wants, and also intends to trick the townspeople.
Thus, the correct answers are the first, third, and fourth options.
