Given the task definition, example input & output, solve the new input case.
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.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input case for you: 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?
