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 input: 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.
Example output: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: 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.
Q: Passage: After a hotel reservation mix up, two sisters Karen and Jennifer, and their friend Vicki Thompson, meet a friendly, but shady character named Ernest Keller who is the owner of a small town museum. Ernest convinces the three women into accepting an invitation for cheap room and board at his large farmhouse outside of town where his wife Virginia also lives. Once there, Jennifer and Karen leave for the holiday parade fair which Jennifer, a news reporter, is reporting on. At the festival, Jennifer is met by her soon to be ex-boyfriend, Tony, who gets her to stay behind to talk about their relationship.
Meanwhile, back at the house, Vicki prepares to take a nap in her room, but is attacked by an unseen figure. The unseen eventually begins to pull Vicki into a floor vent when she tries to escape. The grate of the vent slams down on her neck, killing her. At the parade, Karen leaves Jennifer and Tony to talk, and makes her way back to the house alone—where she too is then attacked and killed by the unseen, as it attempts to pull her by her scarf through a vent into the basement. Virginia, who had been in the barn slaughtering a chicken, soon after comes inside to find the bodies of both Vicki and Karen.
When Ernest arrives back at the house, he finds Virginia in shock. At this point, it is revealed through flashbacks that Virginia and Ernest are, in fact, brother and sister, and that Ernest had murdered his own sadistic father over 20 years ago in order to maintain the unnatural relationship. It is also revealed that they have an inbred son named "Junior" who has been kept locked up in the basement; the viewer also learns that Junior is often viciously beaten by Ernest. Ernest then convinces the subservient Virginia, who the viewer now realizes is taken advantage of by Ernest, that Jennifer must be killed upon her return, in order to keep everything under cover.
A:
