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: Los Angeles. The season of El Niño. Frank is a high school student obsessed with heavy electron resurrection (reanimating corpses soon after death). One night Frank's neighbor and fellow student Lance throws a party and as a joke invites Karl, an outsider in school. When Karl shows up, however, he gets into a fight with Lance and Tuttle and dies after falling into an empty swimming pool. Frank sees Lance and Tuttle attempting to dump the body and offers to reanimate the corpse for them. Stealing a brain from his father's (Judge Reinhold) lab, Frank successfully resurrects Karl and returns him home.
The next day Frank is befriended by Lance and Tuttle, and Karl appears to be changed into a cool kid in school. Frank, suspicious of Karl's personality change, discovers that the brain he used was that of a murderer named Skeeter Wayne Dobbs. Revealing this to Karl, Karl and Frank agree to keep this a secret from the others. Karl then helps Frank to get a date with his crush Macy by throwing a party using money stolen from the homecoming dance. At the dance Karl beats up Lance and Tuttle and leaves with Andrea who soon goes missing. Realizing Karl has stolen the homecoming money and potentially murdered Andrea, Frank confronts Karl who dismisses his concerns and invites him to a Halloween party that night. Macy, thinking Frank stole the money, breaks up with him and goes to the party alone.
Output:
Who used a brain of a murderer to reanimate a corpse?
