How does Huck scam the two con-artists? 1. He tricks them into turning themselves in to the police. 2. He convinces them that he is their long-lost younger brother; 3. he steals the money they stole from their victims; or 4. he lets the raft they are on float away during the night while they are sleeping.

The correct answer is 1. He tricks them into turning themselves in to the police.

In Mark Twain's novel "Adventures of Huckleberry Finn," Huck comes across two con-artists, also known as frauds or "the Duke" and "the King." These two men often deceive people to make money. However, Huck recognizes their true nature and decides to outsmart them.

Huck comes up with a plan to expose the frauds and bring them to justice. He writes a letter to a nearby town's sheriff, pretending to be a young boy who informs him about the presence of two criminals. Huck includes specific details about the crimes they have committed to convince the sheriff of the truth.

Later, when the Duke and the King attempt to deceive a local community by posing as a deceased man's long-lost brothers, Huck executes his plan. He slips out of the situation and finds a way to deliver the letter to the sheriff anonymously. This prompts the sheriff and a group of townspeople to capture the frauds and bring them to trial.

Therefore, Huck successfully scams the two con-artists by tricking them into turning themselves in to the police, putting an end to their deceitful activities.
