You will be given a definition of a task first, then some input of the task.
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.

Passage: Harper is a bank robber posing as a traveling salesman. He arrives in town, soon to be joined by sadistic benzedrine addict Dill and bookish Chapman.
Boyd Fairchild is manager of the local copper mine, troubled by his philandering wife. He considers an affair with nurse Linda Sherman, though he truly loves his wife. His associate, Shelley Martin, has a happy home life, but is embarrassed that his son believes he is a coward because he did not serve in World War II.
Subplots involves a peeping-tom bank manager, Harry Reeves, and a larcenous librarian, Elsie Braden. As the bank robbers carry out their plot, the separate character threads are drawn together. Violence erupts during the robbery. Fairchild's wife is slain and bank manager Reeves is wounded. Martin is held hostage on a farm with an Amish family. With the help of the father, he defeats the crooks in a savage gunfight. In the aftermath, Martin becomes a hero to his son, and Linda comforts Fairchild as he grieves for his wife.
Output:
What is the first name of the person who works with the copper mine manager?
