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.

[EX Q]: Passage: In the early 1980s, teenagers Martin Asher and Matt Soulsby meet on a bus to Mont-Laurier, Quebec. Seemingly uncertain of their ultimate destination, the two talk about their plans for the future. When their bus breaks down, the two acquire a car from a nearby garage. While Martin is driving, a tire blows. Matt struggles to change the tire and Martin comments on how he and Matt are both about the same height, and kicks Matt into the path of an oncoming truck, killing both him and the driver. Taking Matt's guitar and clothes, he walks away singing in a voice similar to Matt's. 
Twenty years later, a successful FBI profiler, Illeana Scott, is summoned to help out the authorities in Montreal in apprehending a serial killer who assumes the identities of his victims,  enabling him to travel undetected across North America. Martin's mother Rebecca claims to have seen her son alive and well on a ferry to Quebec City, leading to the body believed to have belonged to him being exhumed for forensic examination, and he becomes the primary suspect. Illeana, who has difficulty adjusting to her new surroundings and is distrusted by her local colleagues, interviews art dealer James Costa, an eyewitness who saw Asher kill his last victim. Costa makes a drawing of the killer and the authorities manage to track down the man's apartment, only to find a decaying corpse chained up in the ceiling. Illeana goes to Rebecca's house to question her about her son, and while snooping around discovers a hidden passageway behind a cabinet that leads to a secret room used to house young Martin, an unwanted and unstable younger child whom Rebecca neglected and saw as inferior to her elder son, whom Martin ultimately killed out of jealousy. Illeana is attacked by a hidden assailant, who escapes before she can identify him.

[EX Q]: Passage: In 1946, after fighting in World War II, two former United States Air Force pilots in North Africa, Brynie MacKay and Mike Brewer are forced to work for Lee Harris, an international smuggler to get money needed for their return to civilian life.  The smuggler wants them to fly to France, with Egyptian cotton cargo. When Brynie finds that their real cargo is contraband cigarettes, he extorts Harris for more money. In retaliation, Harris plants narcotics on Brynie's aircraft and informs Colonel Wilson at U. S. Counterintelligence.
With Byrnie's aircraft impounded and his money seized, Elena, Harris's mistress comes to his aid. Harris exacts a promise for 12 more illegal cargo flights, but Mike warns that they will both be killed if they go ahead with this scheme. When Mike tries to trap Harris by informing Col. Wilson about the smuggling runs, Harris, who is flying with the two pilots, kills Mike, but is knocked out by Byrnie.
Fearing Harris's gang is waiting for him at the prearranged destination, Byrnie lands his aircraft at an abandoned military air strip and informs Wilson where the contraband can be found.  With Elena at his side, Byrnie then escapes to North Africa. When Harris tracks them down, Brynie overcomes Harris and turns him over to Wilson, and because of the deal Mike had made, is released. Byrnie decides to return to the United States with Elena and become a teacher, his former profession.
[EX A]: What is the first name of the man that extorts the smuggler after discovering what the cargo is?

[EX Q]: Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.".
