Question

thousands of chinese laborers immigrated to the united states in the 1800s. many of them brought traditional medicines, including snake oil made from the chinese water snake. in time, some people made fake versions of the remedy, and when the fakes were eventually exposed as ineffective, the salesmen gained a poor reputation. what is the meaning of the allusion in the sentence below? in the republican primary, the senator labeled his opponent a snake oil salesman. a person with unusual solutions an unhealthy person a person making false promises

Explanation:

The passage explains that Chinese laborers brought snake oil, and later fake versions were made, leading snake oil salesmen to have a poor reputation for selling ineffective (fake) remedies. In the sentence, labeling an opponent a "snake oil salesman" alludes to this history—implying the opponent makes false promises (like selling fake, ineffective products). The other options don't match: "unusual solutions" and "unhealthy person" are irrelevant to the snake oil context.

Answer:

a person making false promises
