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: LAPD Officer Frank Dooley is framed for the theft of a television set by two corrupt detectives. He is dismissed from the force, but escapes criminal punishment. The court's next case features hapless defense attorney Norman Kane attempting to defend a white supremacist leader, who threatens him with death should Kane fail to keep him out of prison. Kane reveals his ineptitude and the death threat to the judge, who agrees to render a long sentence if Kane promises to leave law behind.
Dooley and Kane meet when they both apply for work at Guard Dog Security, run by "Captain" Clarence O'Connell and part of a union represented by Klepper and Lazarus. Becoming licensed security guards after a single afternoon of training, Dooley and Kane are made partners by supervisor Maggie Cavanaugh and assigned to night duty at a pharmaceutical warehouse. Ordered to take a lunch break by senior guard Bruno, Kane happens upon an armed robbery of the warehouse and calls Frank for help, but they prove no match for the thieves.
The next day, the pair are berated by O'Connell for their failure. While venting their anger toward O'Connell, Maggie reveals that she is his daughter. Dooley and Kane then attend a meeting of the union, where Kane's attempt to file a grievance against Guard Dog is quashed by union president Michael Carlino. Kane pointedly questions Carlino about how the union dues, adding to about $4 million per year, are spent. After Kane rejects an evasive answer from treasurer Lou Brackman, Carlino threatens Kane should he ever attend another union meeting.
Output:
What is the nickname of Maggie's father?
