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 blacksmith and swordsmith John is tutored at the court of King Arthur, but as a commoner he can't hope to win the hand of Lady Linet, daughter of the Earl of Yeonil. The Earl's castle is attacked by Saracens and Cornishmen disguised as Vikings and his wife is killed, making him lose his memory. The attack was part of a plot by the Saracen Sir Palamides and the pagan Cornish King Mark to overthrow Arthur and Christianity and take over the country, whilst pretending to be Arthur's friends and allies - Palamides is a knight of the round table and Mark has faked his own baptism.John accuses Palamides' servant Bernard of murder before Arthur, who grants him three months' grace to prove the accusation or face execution himself. Another knight, Sir Ontzlake, takes pity on John and trains him in swordplay so that he can take on an alternative secret identity as the wandering Black Knight. The "Vikings" raid a newly founded monastery and take Lady Linet and its monks to Stonehenge for a pagan sacrifice, but the Black Knight arrives and saves her, closely followed by Arthur and his knights, who defeat the pagans and destroy Stonehenge.
Sir Palamides tricks the Lady Linet into his castle to try to get her to reveal the Black Knight's identity, but John is informed of this and saves her, still in disguise. Sir Ontzlake then sends him to King Mark's castle, where a pro-Arthur woodcarver shows him a secret tunnel into the royal chambers. John arrives in time to overhear Mark and Palamides finalising their plot but Palamides beats him back to Camelot, tricking Arthur into thinking that the Black Knight is leading the Viking raids. John arrives dressed as the Black Knight and despite revealing his identity is briefly imprisoned until Lady Linet and Sir Ontzlake free him, with the latter standing bail for John to Arthur.

Output: Who loses his memory after his wife is killed?

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. 146575), 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: Though frequent performing kept them apart for several years, Sasha and Digweed announced that they would reunite for a few Australian performances. In November 2006, the duo performed at several venues, including Sydney, Brisbane, and Melbourne as well as numerous tour dates throughout 2007. In 2008, Sasha and Digweed kicked off an American tour with a performance at the Winter Music Conference. The duo played at mainly larger venues on the weekends and smaller (750-1000 people) shows on weekdays. Sasha described their music as "driving and dark" with "a little throwback of Twilo sounds".Sasha runs a music studio and lives in New York City, and maintains a house in London. He brings his wife with him on his frequent tours. Sasha finds the constant touring to be physically tiring, though he also feels that he thrives on it. While fans may regard Sasha to be a DJ "hero", he is uneasy with fame; Sasha considers himself "shy at heart" and is typically uncomfortable discussing his personal life. He has mentioned on numerous occasions that he is so busy with DJing and production that he rarely has any free time. However, he enjoys watching football, cooking, and sampling the cuisine of the countries he visits.
The movie "New Emissions of Light & Sound" won the Best Original Score at the X-Dance Film Festival. The score was made up of new and previously unreleased tracks.Sasha and Digweed have re-united again in recent years. The iconic duo Sasha & John Digweed performed a Back to Back set at the Ministry of Sound in London on 24 March 2016. Shortly there after, the Duo announced a list of tour dates for September 2016 to re-launch themselves in a series of Gigs and performing Back to Back.
