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 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.

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

Passage: In 1981 Afghanistan, a Soviet tank unit viciously attacks a Pashtun village harboring a group of mujahideen fighters. Following the assault, one of the tanks—commanded by ruthless commander Daskal (George Dzundza)—takes a wrong turn through a mountain pass and enters a blind valley. Taj returns to discover the village destroyed, his father killed, and his brother martyred by being crushed under Daskal's tank. As the new khan following his brother's death, Taj is spurred to seek revenge by his cousin Moustafa, an opportunistic scavenger. Together they lead a band of mujahideen fighters into the valley to pursue Daskal's tank (which they call "The Beast"), counting on their captured RPG-7 anti-tank weapon to destroy it.
Lost, isolated, and with their radio damaged in the attack, the tank crew set out to find Kandahar Road and return to Soviet lines. While camping for the night, Afghan communist crewman Samad educates the reluctant tank driver, Konstantin Koverchenko, about the Pashtun people's code of honour, Pashtunwali; particularly nanawatai, which requires that an enemy is to be given sanctuary if he asks.

Ex Output:
What is the name of the crewman who educates the reluctant tank driver?

Passage: Sonora Webster lives with her sister and abusive aunt during the Great Depression.  She learns that because of her accidentally letting the cows loose and her suspension from school, her treasured horse Lightning has been sold and she will be placed in an orphanage.  Instead, Sonora slips out of the house during the night. She ends up at a county fair and sees a performance by Marie, a diving girl who rides a horse off a platform, and aspires to do the same. Doc Carver, Marie's employer, tells her she is too young but gives Sonora a job as a stable hand due to her ability with horses, and she begins traveling with them. Doc's son Al wins a wild horse in a card game and Sonora names him Lightning. She later surprises Doc by taming and riding Lightning, so he promises to train her as a diving girl if she can mount it while it's moving, which she succeeds after multiple attempts.  
Marie falls and dislocates her shoulder, leaving her unable to perform, and Sonora steps in. Although she has never dived with Lightning, their first jump is successful.  Marie becomes jealous, and as Doc tires of her diva-like behavior, she quits rather than share billing with Sonora. Al develops a romance with Sonora that strains his relationship with his father, leaving after a particularly bad fight.  Al promises to write to Sonora, but Doc hides his letters.  As Doc and the new stable hand Clifford leave the farm in search of work, Lightning falls ill with colic. Al returns, and he and Sonora work together to heal Lightning. Doc fails to find any jobs, but Al announces he has arranged a six-month contract to perform at the Steel Pier in Atlantic City, New Jersey, reconciling father and son. Doc passes away en route from a heart attack, and Al assumes his father's role as show presenter.  Sonora searches for Doc's jacket to give Al confidence on his first show, and finds one of Al's letters inside, confessing his love for her, letting him know she feels the same.

Ex Output:

Who had a horse named Lightning taken away?
