TASK 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.
PROBLEM: Passage: A man unveils a valuable painting he picked up for $50,000 and is killed. A card with a large black ace (of spades) is put on his chest. Another "Black Ace" victim. The killer sends his victims a Black Ace card, warning them they are to die and then kills them, his way of taunting the police. Neil Broderick, an author, intends writing a book about him and is on his way to see Thornton Drake to get more information about him. Austin Winters is his secretary and Neil met his daughter Martha on the train, on the way to Chicago.
Drake has just received a Black Ace, with the words: "At seven tomorrow night", the time he is to be killed. Two plainclothes cops arrive from police headquarters, having had a call, Clancy and Dugan (both incompetents). Martha suggests that they leave for Drake's Louisiana plantation tomorrow morning and be far away from there at seven tomorrow night. Drake agrees and suggests they all go. On the flight, the lights go off for some seconds and when they come on again, Austin Winters is dead without a mark on him.
At the plantation, Clancy ineptly questions the suspects till Neil points out that they are now in another state, so out of their jurisdiction. Neil goes to another room and makes a phone call, then signals to someone outside. After he finishes his call, the line is cut. Meanwhile one of the pilots has taken off in the plane, leaving the other pilot, Henderson, behind who claims he does not know anything though he was out of the cockpit when Winters was killed.
The coroner finds a letter on the dead man which is to be read if Winters dies. It will reveal the identity of the Black Ace. Clancy starts reading it aloud and unsurprisingly the lights go off and the letter has vanished when the lights are turned on again. People locked in their rooms that night and Neil has a hidden car outside signal to him.

SOLUTION: Who is Neil Broderick writing a book about?

PROBLEM: Passage: Following the seven performances on the Joshua Tree Tour, U2 did not perform "Mothers of the Disappeared" until 1998, on the fourth leg of the PopMart Tour. It was played at three concerts in Argentina and once in Chile, concluding all four shows. Bono sang "el pueblo vencerá" at the end of each performance. The first rendition was on 5 February 1998 in Buenos Aires, where it was performed with the Madres accompanying them onstage. The song was played by just Bono and the Edge and was set against footage of the Madres on the video screen. At the conclusion of the song, the band members faced the Madres and applauded, an act in which the rest of the audience joined. Part of the performance was later included on the television documentary Classic Albums: The Joshua Tree.The cost of the tickets was too high for many fans in South America, so the band broadcast the 11 February concert in Chile live on television. Knowing that many people in the country would be watching, they played "Mothers of the Disappeared" in place of "Wake Up Dead Man". The stadium in which the concert was held had been used as a prison camp by Pinochet's regime following the coup d'état. Again it was performed solely by Bono and the Edge against footage of the Madres, and they invited the women to join them onstage a second time. The Madres held up photographs of their children and spoke about them briefly during the performance, an act which received a mixed reception from the audience. Bono made a plea to Pinochet, asking him to "tell these women where are the bones of their children.""Mothers of the Disappeared" was performed again on the fourth leg of the Vertigo Tour, on 26 February 2006 in Santiago and 2 March in Buenos Aires. Although it was rehearsed by the full band, it was played only by Bono and the Edge in an arrangement similar to the one from the PopMart Tour. The Edge performed the song on a charango that Chilean President Ricardo Lagos had given to Bono earlier that day. It was played at three concerts on the third leg of the U2 360° Tour in place of "MLK". One performance in Istanbul, Turkey was dedicated to Fehmi Tosun, an ethnic Kurd who was kidnapped in October 1995 and subsequently disappeared. The abduction was witnessed by his wife and daughter; no information regarding his disappearance has ever been released.
For the first time in 30 years, a full band arrangement of "Mothers of the Disappeared" returned to U2's live set for the Joshua Tree Tour 2017, on which the group played The Joshua Tree in sequence in its entirety for each show. Eddie Vedder and Mumford & Sons accompanied U2 on-stage in a performance of the song during a 14 May 2017 show in Seattle.

SOLUTION: What had "el pueblo vencerá" sung after each performance?

PROBLEM: Passage: On returning to England, Drake moved into his sister's flat in Hampstead, London, before enrolling at Fitzwilliam College, Cambridge University that October to study English Literature. His tutors found him bright but unenthusiastic and unwilling to apply himself. His biographer, Trevor Dann, notes that he had difficulty connecting with staff and fellow students, and that matriculation photographs from this time portray a sullen young man. Cambridge placed emphasis on its rugby and cricket teams, yet by this time Drake had lost interest in sport, preferring to stay in his college room smoking cannabis, and listening to and playing music. According to fellow student Brian Wells, "they were the rugger buggers and we were the cool people smoking dope".In September 1967, Drake met Robert Kirby, a music student who went on to orchestrate many of the string and woodwind arrangements for Drake's first two albums. By this time, Drake had discovered the British and American folk music scenes, and was influenced by performers such as Bob Dylan, Donovan, Van Morrison, Josh White and Phil Ochs. He began performing in local clubs and coffee houses around London, and in February 1968, while playing support to Country Joe and the Fish at the Roundhouse in Camden Town, made an impression on Ashley Hutchings, bass player with Fairport Convention. Hutchings recalls being impressed by Drake's guitar skill, but even more so by his image: "He looked like a star. He looked wonderful, he seemed to be 7 ft [tall]."
Hutchings introduced Drake to the 25-year-old American producer Joe Boyd, owner of the production and management company Witchseason Productions. The company was, at the time, licensed to Island Records, and Boyd, who had discovered Fairport Convention and introduced John Martyn and the Incredible String Band to a mainstream audience, was a significant and respected figure on the UK folk scene. He and Drake formed an immediate bond, and Boyd acted as a mentor to Drake throughout his career. Impressed by a four-track demo recorded in Drake's college room in early 1968, Boyd offered Drake a management, publishing, and production contract. According to Boyd:In those days you didn't have cassettes—he brought a reel-to-reel tape [to me] that he'd done at home. Half way through the first song, I felt this was pretty special. And I called him up, and he came back in, and we talked, and I just said, "I'd like to make a record." He stammered, "Oh, well, yeah. Okay." Nick was a man of few words.According to Drake's friend Paul Wheeler, Drake had already decided not to complete his third year at Cambridge and was excited by the contract.

What is the name of the person that was portayed as a sullen young man?
