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: A janitor is seen cleaning in a laboratory and interrupting a scientist as he asks to clean the floors of the area he is working in. The scientist agrees and retreats to the hallway to a vending machine. The janitor accidentally knocks off a life monitor attached to a man, in his attempt to revive the man he gives chest compresses but his hands rip through the flesh as the man awakens and attacks the janitor. Moments later the janitor attacks the scientist in the hallway.
[EX A]: What was the janitor doing just before he attacked the scientist?

[EX Q]: Passage: The siege was captured by Pathé News cameras—one of their earliest stories and the first siege to be captured on film—and it included footage of Churchill in attendance. When the newsreels were screened in cinemas, Churchill was booed with shouts of "shoot him" from audiences. His presence was controversial to many and the Leader of the Opposition, Arthur Balfour, remarked, "He [Churchill] was, I understand, in military phrase, in what is known as the zone of fire—he and a photographer were both risking valuable lives. I understand what the photographer was doing, but what was the right hon. Gentleman doing? That I neither understood at the time, nor do I understand now." Jenkins suggests that he went simply because "he could not resist going to see the fun himself".An inquest was held in January into the deaths at Houndsditch and Sidney Street. The jury took fifteen minutes to reach the conclusion that the two bodies located were those of Svaars and Sokoloff, and that Tucker, Bentley and Choate had been murdered by Gardstein and others in the course of the burglary attempt. Rosen was arrested on 2 February at work in Well Street, Hackney, and Hoffman was taken into custody on 15 February. The committal proceedings spread from December 1910—with Milstein and Trassjonsky appearing—to March 1911, and included Hoffman from 15 February. The proceedings consisted of 24 individual hearings. In February Milstein was discharged on the basis that there was insufficient evidence against her; Hoffman, Trassjonsky and Federoff were released in March on the same basis.The case against the four remaining arrested gang members was heard at the Old Bailey by Mr Justice Grantham in May. Dubof and Peters were accused of Tucker's murder, Dubof, Peters, Rosen and Vassilleva were charged with "feloniously harbouring a felon guilty of murder", and for "conspiring and agreeing together and with others unknown to break and enter the shop of Henry Samuel Harris with intent to steal his goods." The case lasted for eleven days; there were problems with the proceedings because of the language difficulties and the chaotic personal lives of the accused. The case resulted in acquittals for all except Vassilleva, who was convicted of conspiracy in the burglary. She was sentenced to two years' imprisonment; her conviction was later overturned on appeal.After the high levels of criticism aimed at the Aliens Act, Churchill decided to strengthen the legislation, and proposed the Aliens (Prevention of Crime) Bill under the Ten Minute Rule. The MP Josiah C Wedgwood objected, and wrote to Churchill to ask him not to introduce the hard-line measures "You know as well as I do that human life does not matter a rap in comparison with the death of ideas and the betrayal of English traditions." The bill did not become law.
[EX A]: Which of the people arrested was released first?

[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 A]:
