Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: In 1841, Solomon Northup is a free African-American man working as a violinist, living with his wife and two children in Saratoga Springs, New York. Two white men, Brown and Hamilton, offer him short-term employment as a musician if he will travel with them to Washington, D.C. However, once they arrive they drug Northup and deliver him to a slave pen run by a man named Burch. Northup proclaims that he is a free man, only to be savagely beaten with a wooden paddle and then a leather belt.
Northup is later shipped to New Orleans along with other captive African Americans. He is told by the others that if he wants to survive in the South, he must adapt to being a slave and not tell anyone he is a free man. A slave trader named Theophilus Freeman gives Northup the identity of "Platt", a runaway slave from Georgia, and sells him to plantation owner William Ford. Ford takes a liking to Northup and gives him a violin. However, tension grows between Northup and plantation carpenter John Tibeats which ends with Northup savagely beating and whipping Tibeats. Tibeats and his group try to hang Northup. Although they are not successful, Northup is left on the noose for hours before he is finally cut down. To save Northup's life, Ford sells him to another slave owner named Edwin Epps. In the process, Northup attempts to explain that he is actually a free man, but Ford tells him he is too afraid and that he cannot help him now.
Output:
What city is Solomon Northup sold in?
