Task: Question Generation
Input (English): Passage: A series of murders of rich young women throughout the area of Globe, Arizona bear the distinctive signature of a serial killer. Clues lead Detective Charles Mendoza to visit Paul White, a sound expert installing hi-fi systems in wealthy people's homes. His special talent is to make a noise which echoes through the air cavities in his head and shows him where the sound of the speakers should come from and echo in the room. He is married to Joan, whom, ten years earlier, he had seduced away from Mike DeSantos, who was her then boyfriend. Joan and Paul have a daughter, Danielle, together.
Paul, installing equipment at Dr. Sutter's home, proximal to the most-recent murder, is approached by Detective Mendoza-- they have a cordial conversation about sound equipment, but it turns abruptly, when Mendoza asks Paul if he still hunts. Mendoza questions Paul about whether he knew the victim, and then asks him about the tires on his van-- a tread pattern that has been located at the scene of the murder.
Mendoza meets with his partner Phil at the police station, where Phil has gathered criminal record information on Paul-- they speculate on what kind of person he might be based on that information. Mendoza, working from photos of the crime scene, begins to identify some aspects of the killer's M/O.
Paul visits Fred, proprietor of the local diner-- Fred mentions that Ann Mason has been asking after Paul, ostensibly to work on her satellite system.
Output (English): What is the first name of the person who is married to Joan?
