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: Hitman Trabucco has been hired to eliminate Rudy "Disco" Gambola before he testifies against fellow members of the Mob, but completing the contract becomes problematic once he encounters suicidal Victor Clooney, an emotionally disturbed television censor staying in the room adjacent to his in the Ramona Hotel in Riverside, California.
When Victor climbs onto the ledge outside his window, Trabucco convinces him not to jump by agreeing to drive him to the Institute for Sexual Fulfillment, the nearby clinic where Victor's wife Celia, a researcher for 60 Minutes, is gathering information for a segment on the program.
At the clinic, Victor discovers Celia has fallen in love with Dr. Zuckerbrot, who is concerned her husband's suicide will reflect badly on his practice. Trabucco accidentally is injected with a tranquilizer intended for Victor, who volunteers to fulfill the killer's contract when Trabucco's vision is impaired. After overcoming assorted complications, Victor completes his task. However, despite Victor's high hopes, Trabucco has no intention of sticking together and parts ways with him following their escape.
Trabucco retires to a tropical island, where he unexpectedly is joined by his nemesis after Celia runs off with Dr. Zuckerbrot's female receptionist to become a lesbian couple. Desperate to see Victor gone, Trabucco suggests to his native attendant to reinstate the old custom of human sacrifices for the local volcano ...
Output:
What is the last name of the person who is staying in the room next to Victor?
