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.

Question: Passage: Young David Balfour arrives at a bleak Scottish house, the House of Shaws, to claim his inheritance after his father. The house and land have been under the custodianship of his father's brother, Ebeneezer Balfour, but on reaching adulthood, the land and property become David's. Ebeneezer is having none of it, however, so he first tries to murder him, then has him kidnapped by sea captain Hoseason, with whom he has "a venture for trade in the West Indies". David is shipped off to be sold as a slave in the Carolinas. He strikes up a friendship with Alan Breck, escaping from Prince Charles Edward Stuart's defeat at Culloden. Breck is in a cobble which is run down in the fog by Hoseason's ship and once aboard, asks Hoseason to take him to France. When Hoseason refuses, Breck offers him 60 guineas to put him down on Loch Linnhe.
On discovering that Breck has a money belt full of Jacobite gold, Hoseason and his crew try to kill Breck, but he is forewarned by David and the two kill half a dozen of the crew before the others retreat. Hoseason offers terms to end the fighting, but the ship runs aground. Only Breck and Balfour appear to survive and they manage to get to land. They set out for Edinburgh, dodging the ruthless Redcoats. Numerous adventures follow as they meet up with Breck's family, friends and foes alike. These include Breck's cousin, James Stewart, and his daughter Catriona, with whom David falls in love.

Answer: Who does Ebeneezer Balfour try to murder?


Question: Passage: It is the Dark Ages, and the Church is fighting against 'black magic'. The medical knowledge of Greek physicians like Hippocrates and Galen had been lost to the medicine of medieval Europe. In 11th-century England, travelling barber surgeons attempted to supply medical care to the ordinary population, often at the risk of the Church persecuting them for witchcraft.
Robert Cole has an extraordinary gift, where he can sense when someone left untreated has a terminal illness. He notices this for the first time when he feels it as a little boy when his sick mother is dying of appendicitis, a disease of which he was unaware. The young orphan joins an itinerant barber-surgeon who calls himself Barber. Barber teaches him the basics of medieval medicine, with services such as cupping therapy, bloodletting, and dental extraction. Even as an apprentice Rob recognizes the limitations of these simple practices. When Barber suffers from a cataract, Rob consults a Medicus for him. This Jewish doctor completely heals Barber of his cataracts. He learns a little bit of Jewish culture. He speaks with two children, Jesse and Benjamin. There, Rob sees for the first time a world map, and learns of the famous Ibn Sina, who teaches medicine in distant Persia. So he decides to train there to become a physician. During the Islamic Golden Age, the medicine in the medieval Islamic world is far more advanced than in Europe. The doctor, scientist and philosopher Ibn Sina teaches in Isfahan, the most important school for aspiring practitioners in the world at that time.

Answer: Who does the boy who can sense terminal illness go to apprentice for?


Question: Passage: In August 2013, Jared Leto told MTV News that he was preparing to shoot a short film for "City of Angels". While he did not reveal much about the music video concept, he added: "It's going to be powerful and emotional and definitely something special." The shooting took place from August 16–17 in Los Angeles, filming multiple monoliths and murals. Leto interviewed celebrities who joined the three members of Thirty Seconds to Mars in sharing their visions about Los Angeles. He also recruited Michael Jackson and Marilyn Monroe impersonators as well as homeless people in the production of the video. After filming, Leto talked about the inspiration behind the video, stating, "Telling stories is a big part of what I do, so it was a really natural and comfortable thing. I think because I did all the interviews myself—I talked to fellow artists and they felt really comfortable. They shared a side of themselves that we don't share very often." Footage from the song's lyric video, which was shot atop the Hollywood Hills, was used for a part of the short film that featured Leto singing the song against the backdrop of a Los Angeles sunset.The short film was produced by Emma Ludbrook, Allan Wachs and Jared Leto, who also directed. Although it is billed as a "Bartholomew Cubbins Film" (Leto's  longtime pseudonym), "City of Angels" is the first directorial project directly credited to Jared Leto. He explained, "It was the first time I'd ever done that. I'd used several different names, but it was just such a personal thing. I thought it was appropriate to put my name on that piece." Previous collaborator Devid Levlin served as director of photography. It was edited by Leto, Benjamin Entrup and Mischa Meyer. The short film included commentary from Kanye West, Christopher Lloyd Dennis, Juliette Lewis, Heather Levinger, Haywood, Lindsay Lohan, Olivia Wilde, Steve Nash, Ashley Olsen, Lily Collins, James Franco, Selena Gomez, Alan Cumming, Anthony Warfield, Jovan Rameau, Holly Beavon, Shaun White, Corey Feldman, and Yosh. "City of Angels" marked the second collaboration of Thirty Seconds to Mars with Kanye West, as they first worked together on the track "Hurricane" (2010).

Answer:
What is the last name of the person who recruited Michael Jackson and Marilyn Monroe impersonators?
