Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: 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.

Now, solve this instance: Passage: After a job in Monte Carlo, an English jewel theft ring returns to Paris. Suave cat burglar Oliver Lane, fashioned the "Solitaire Man" in the newspapers after seven years of eluding Scotland Yard, proposes marriage to his lovely accomplice Helen and informs her he has bought a country house in Devonshire to which they can all retire. However unstable Robert Bascom, drug-addicted after his experiences in the Great War, also loves Helen and wants to continue on his own. He presents Oliver with the "Brewster necklace" that he burgled from the British Embassy while he dined there with his former colonel. Realizing Bascom would be the only suspect and his arrest would lead back to all of them, Oliver returns the Brewster necklace to the safe just as an inspector from Scotland Yard tracking the Solitaire Man arrives at the embassy. Before Oliver can make his escape, a second man sneaks in and steals the necklace but is interrupted by the inspector, who recognizes the thief but is shot and killed by him. Oliver struggles in the dark with the killer during his getaway and grabs the necklace and part of the killer's watch chain.
Student:
Who returned the "Brewster Necklace" to the British Embassy?
