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: The film opens with Stanley on his boat in the middle of Summit Lake. After speaking with his agent, Regan over the phone, Stanley accesses a hidden room in his house revealing a young woman who is chained to the floor by her ankle.  He greets the woman and calls her Kimberly as he places a plate of food in front of her.  When he leaves the room, Kimberly walks over to the mirror and begins to cry, unaware that Stanley is studying her on the other side.
Afterwards, Stanley brings her a fresh change of clothes and instructs her to dress, before gagging her with an orange and binding her hands behind her back.  He forcibly escorts her onto his boat and drives out to the middle of Summit Lake, where he ties a cement block around her ankles.  Curious about her predicament, he asks Kimberly how she feels, but the terrified woman does not respond. Stanley then pushes her into the lake, but promptly pulls her back up by the hair to study her expression before letting her sink to the bottom.  
Later, Stanley returns home to resume working on his script using the details he had gleaned from his latest victim.  The next morning, he dives to the bottom of Summit Lake to tend his "garden", which consists of several women kidnapped and drowned in a similar fashion.  Seeking yet another victim, Stanley discovers Mallory, a young woman working at a movie theater.  Intrigued by her self-confessed fear of water, Stanley follows Mallory after she leaves work and swerves in front of her, slamming the brakes on his van and forcing their vehicles to collide.
Output:
Who is keeping Kimberly locked up?
