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: Eric Stoltz plays John Dantley, an NTSB officer sent to O'Hare Airport in Chicago to investigate a collision between Global Airlines Flight 1025 (a Boeing 757-200 from Los Angeles to Washington D.C.) and PDO Cargo flight 342 (a Boeing 727-200F flying westbound cargo plane), where 185 people are killed.
Charles Martin Smith plays Henry Drake, an air traffic controller who insists his radar system malfunctioned when the planes were being cleared for landing. When the rest of air traffic control dismiss Drake and blame the incident on human error, Dantley must discover the truth about the crash: Was Drake — a high-strung individual who already didn't get along with his co-workers — simply incompetent at his job or did Drake's co-workers and superiors know about and/or had been previously been warned about the aging radar system showing signs of seriously malfunctioning and crashing at critical times (and thus liable to lead to deadly situations such as the one that happened), but instead of taking action ignored the warnings and initiated a cover-up?.
Example Output: What were the two flights that an NTSB officer was sent to O'Hare Airport to investigate a collision between?

Example Input: Passage: In February 1828, shortly before his 41st birthday, Etty soundly defeated John Constable by 18 votes to five to become a full Royal Academician, at the time the highest honour available to an artist. By this time, complaints about his supposed indecency were beginning to resurface. All but one of the 15 paintings Etty exhibited at the Royal Academy in the 1820s had included at least one nude figure, and Etty was acquiring a reputation for using respectable themes as a pretext for nudity.For the 1828 Summer Exhibition Etty exhibited three pictures; The World Before the Flood, Venus, the Evening Star and Guardian Cherubs. (The latter was a portrait of the children of Welbore Ellis Agar, 2nd Earl of Normanton, and was the only non-nude painting exhibited by Etty at the RA in the 1820s.) Although similar to his earlier works, they were technically more accomplished. Both The World Before the Flood and Venus attracted positive reviews in the press and were sold during their exhibition for substantial sums, although the purchase by the Marquess of Stafford of The World Before the Flood—a work containing scantily clad figures of both sexes—drew a pointed comment in The Gentleman's Magazine that it "will serve to accompany the private Titians of that nobleman". Despite the increasing number of complaints in the press about his use of nudity, respect for Etty from his fellow artists continued to rise, and in 1828 the British Institution awarded him £100 in recognition of his talent.
As soon as the 1828 Summer Exhibition was over, Etty stopped work on other projects to concentrate on a diploma piece, without which he could not become a Royal Academician. This piece, Sleeping Nymph and Satyrs, was presented to the Academy in October, and in December 1828 Etty became a Royal Academician.
It appears to me then that virtuous happiness being our lawful aim in life, that having Academic Rank and Fame the next thing to be considered (if God approve) is to seek that Decent Competency which shall make my latter days comfortable and happy, which I hope if it please Him, to be able to do by the time I am fifty—by occasionally mixing with my historic pictures a Portrait or two, and to vary and extend my sphere—a classic Landscape or two so that if I can get about 100 a year I may be enabled to retire to my dear native city and spend my latter days in peace.
Example Output: What is the exact title of the diploma piece without which Etty could not become a Royal Academician?

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