Definition: 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.
Input: 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.
Output:
Who returned the "Brewster Necklace" to the British Embassy?
