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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

OK. solve this:
Passage: Washington, D.C. detective and forensic psychologist Alex Cross heads to Durham, North Carolina when his niece Naomi, a college student, is reported missing. He learns from police detective Nick Ruskin that Naomi is the latest in a series of young women who have vanished. Soon after his arrival, one of the missing women is found dead, bound to a tree, and a short time later, Kate McTiernan is kidnapped from her home.
When she awakens from a drugged state, Kate discovers that she is being held by a masked man calling himself Casanova, and she is one of several prisoners trapped in his lair. She manages to escape and is severely injured when she jumps from a cliff into a river. After she recuperates, she joins forces with Cross to track down her captor, whom Cross concludes is a collector, not a killer, unless his victims fail to follow his rules. This means there is time to rescue the other imprisoned women, as long as they remain obedient.
Clues lead them to Los Angeles, where a series of gruesome kidnappings and murders have been credited to Dr. William Rudolph, known as the Gentleman Caller. Cross's efforts to capture and question Rudolph are foiled when Rudolph escapes. In North Carolina, Cross traces Casanova up the river. Alerted by a gunshot, he discovers Casanova's underground hideout. Rudolph is revealed to be Casanova's partner. Casanova escapes, while Rudolph is shot by Cross. Cross rescues the kidnapped women, including Naomi.
Answer:
