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: Consider Input: Passage: The Annunciation draws heavily on van der Weyden's 1430s Louvre Annunciation, his c. 1455  Saint Columba altarpiece, and the Clugny Annunciation (c. 1465–75), which is attributed to either van der Weyden or Memling. Memling almost certainly was apprenticed to van der Weyden in Brussels until setting up his own workshop in Bruges sometime after 1465. Memling's Annunciation is more innovative, with motifs such as the attendant angels that were absent in the earlier paintings. According to Till-Holger Borchert, not only was Memling familiar with van der Weyden's motifs and compositions, but he might have assisted with the underdrawing in van der Weyden's workshop. The shutters on the right are copied from the Louvre panel, the knotted curtain appears in the Columba triptych's "Annunciation".A sense of movement is conveyed throughout. The trailing edges of Gabriel's garment fall outside the pictorial space, indicating his arrival. The Virgin's "serpentine" pose, with attendant angels supporting her, adds to the sense of flow. Memling's use of color achieves a startling effect. The traditional rays of light are replaced with light color indicators; the white clothes rendered in "icy" blue, the angel to the right in yellow patches seems "bleached by light", the left-hand angel appears to be steeped in shadow, dressed in clothes of lavender and bearing deep green wings. The effect is iridescent, according to Blum, who writes, "this shimmering surface gives [the figures] an unearthly quality, separating them from the more believable world of the bedchamber." The effect deviates from the pure naturalism and realism which typifies Early Netherlandish art, causing a "startling" juxtaposition, an effect that is "unsteadying" and contradictory.

Output: What is the name of the person who might have assisted with the underdrawing in Van der Weyden's workshop?


Input: Consider Input: 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.

Output: What is the first name of the person who becomes a primary suspect?


Input: Consider Input: Passage: An unknown sniper positions himself at the Los Angeles Memorial Coliseum prior to a professional football championship dubbed as "Championship X" (Ten) between Baltimore and Los Angeles  similar to the Super Bowl. He is spotted by a Goodyear Blimp camera. Police and SWAT team are immediately called in by the stadium manager Sam McKeever.
Police Captain Peter Holly, working with SWAT team Sergeant Chris Button, devises a plan to capture the sniper before the conclusion of the game.
Many of the fans attending the game are introduced. They include Steve and Janet (David Janssen and Gena Rowlands), an argumentative middle-aged couple; Stu Sandman, a gambling addict; a Catholic priest, who is a friend of quarterback Charlie Tyler; young married couple Mike and Peggy Ramsay (Beau Bridges and Pamela Bellwood); an elderly pickpocket and his young accomplice (Juli Bridges, the then-wife of Beau Bridges); and football fan Al, who begins flirting with Lucy when he notices her date is more interested in the game than in her.
The stadium's maintenance director, named Paul, discovers the sniper's presence and attempts to confront him. The sniper strikes Paul with the butt of his rifle, and, undetected by fans, causes Paul to fall several stories, leaving him severely injured. SWAT team members position themselves on stadium light towers to take aim on the sniper's nest.
Mike Ramsay spots the sniper with his binoculars. He reports it to the police, but rather than thank him, they question him suspiciously and then physically overpower him.
Shortly after the game's two-minute warning, the SWAT team is given the green light to go after the sniper. Seeing that he is surrounded, the sniper opens fire, shooting randomly into the crowd. His shots cause a massive riot in which the panicked fans spill onto the field.
Output: What is the full name of the person who is questioned after reporting the location of the sniper to the police?
