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.

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

Example Input: Passage: In turn-of-the-century Oakland, California, the teenaged Myrtle McKinley is expected to follow high school by attending a San Francisco business college. Instead, she takes a job performing with a traveling vaudeville troupe, where she meets and falls in love with singer-dancer Frank Burt.
Frank proposes they marry and also entertain on stage together as an act, which proves very popular. Myrtle retires from show business after giving birth to daughters Iris and Mikie, while her husband goes on tour with another partner.
A few years later, less successful now, Frank persuades his wife to return to the stage. The girls are cared for by their grandmother as their parents leave town for months at a time.
Iris and Mikie are school girls when they are given a trip to Boston to see their parents. Iris meets a well-to-do young man, Bob Clarkman, and is permitted to attend an exclusive boarding school there. She is embarrassed by her parents' profession, however, and mortified at what the reaction will be from Bob and all of her new school friends when they learn that her parents are performing nearby.
Myrtle and Frank take matters into their own hands, arranging with the school to have all of the students attend a show. To her great relief, Iris is delighted when her classmates adore her parents' sophisticated act. By the time she's out of school and ready to marry, Iris wants to go into show business herself.
Example Output: What is the last name of the person who falls in love with Frank?

Example Input: Passage: A group of puppies are stolen from a pet store by two thieves. A St. Bernard puppy escapes and sneaks into the Newton family's home. The workaholic father, George Newton, doesn't want the responsibility of owning a dog, but his wife, Alice, and their children, Ryce, Ted, and Emily, convince him. They give him the name "Beethoven" when Emily plays a portion of Ludwig van Beethoven's Fifth Symphony on the piano and the dog barks along to it.
Beethoven grows into an extremely fat adult dog and helps the children overcome their problems: he helps Ryce talk to her crush, scares off bullies for Ted, and saves Emily's life when she falls into an irresponsible babysitter's swimming pool. George, jealous of the affection Beethoven receives, feels neglected as his family fawns over him. His antics ruin a barbecue he is hosting for Brad and Brie, rude, unpleasant venture capitalists looking to invest in and secretly swindle him out of his car freshener firm.
The Newtons take Beethoven to a veterinarian, Dr. Herman Varnick, for a routine medical examination and immunizations. They are unaware that he is involved in unethical and deadly animal experimentation. He speaks to George and tells him of a supposed mental instability among St. Bernards making them potentially dangerous to humans and advises him to watch Beethoven closely for any sign of viciousness. He actually requires large-skulled dogs such as St. Bernards for an ammunition test.
Example Output:
Who is the mother of the girl that plays the piano while the dog barks?
