instruction:
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.

Passage: Nathan Ellis, a 9-year-old maths prodigy, has just lost his father in a car accident. Nathan is diagnosed with autism early in the film, and his father was the only one who was able to connect normally with him. Although Nathan values his mother, Julie, he shuns any physical contact with her and treats her as more of a caretaker than a parent. Wanting to make sure Nathan isn't distracted from his studies, Julie enrolls him in advanced classes at a new school. There, he comes under the tutelage of teacher Martin, also a math genius, who now suffers from multiple sclerosis. Martin sees himself in Nathan, once a promising young mind in the field of mathematics, who gave it all up once he was diagnosed with his illness.
Seven years later, Martin is preparing Nathan to compete for a place in the International Mathematical Olympiad, a prestigious high school competition consisting of the world's best young mathematicians. This year, it is to be held at Cambridge, after a two-week math camp in Taiwan where the students will study for the test that determines the winners. Nathan fears he's not good enough to qualify but ends up doing well enough to accompany 15 other British teenagers to Taiwan.
Suddenly thrust out of his comfort zone, Nathan finds himself no longer the smartest math whiz in the room, and his social anxieties nearly paralyze his performance. He has trouble reading the social cues of others and flinches at the slightest physical contact with another person. Nathan is paired with a female Chinese student, Zhang Mei, who slowly helps him adjust to his new surroundings and helps him fight through his fears. By the skin of their teeth, Nathan and Zhang make the cut to compete in Cambridge.

Passage: In 1932, a luxury yacht is sailing through a channel off the western coast of South America. The captain is worried about the channel lights not matching the charts, but is quickly dissuaded from changing course by the wealthy passengers for the sake of time, including famous big game hunter and author Bob Rainsford. It is a calm evening, with the cheerful passengers relaxing over drinks and a game of cards. Bob and his companions are debating about whether hunting is at all sporting for the animal being hunted after a friend asks if he would exchange places with a tiger he had recently hunted in Africa. Bob replies that there are two kinds of people in the world: those who hunt and those who are hunted.
The ship suddenly runs aground, causing the ship to take on water and heave violently. Water floods the boiler room, causing the ship to explode and sink into the channel. Rainsford and two others manage to get away and cling to wreckage, but the other survivors are eaten by a shark. He swims to a small, lush island. Wandering through the jungle, he sees the channel lights off the shoreline change, and suspects the ship was deliberately led off course to its doom.
He stumbles across a luxury chateau where he becomes the guest of the expatriate Russian Count Zaroff, a fellow hunting enthusiast. Zaroff remarks that Rainsford's misfortune is not uncommon; in fact, four people from the previous sinking are still staying with him: Eve Trowbridge, her brother Martin, and two sailors.
That night, Zaroff introduces Rainsford to the Trowbridges and reveals his obsession with hunting. During one of his hunts, a Cape buffalo inflicted a head wound on him. He eventually became bored with the sport, to his great consternation, until he discovered "the most dangerous game" on his island. Rainsford asks if he means tigers, but Zaroff denies it.
answer:
What is the last name of the person who becomes a guest at a luxury chateau?

Passage: Josephine-Eleonore-Marie-Pauline de Galard de Brassac de Bearn (18251860) married Albert de Broglie on 18 June 1845, and they had five sons together. Although not high royalty, on the occasion of their marriage, they styled themselves Prince and Princesse respectively. Pauline was a highly intelligent and religious woman, who was well read and wrote a number of texts in her lifetime. Her shyness was well known; she was widely considered strikingly beautiful and charming, but those around her would often avoid eye contact so as not to embarrass her. Albert was devoted to his wife, and commissioned the painting after being impressed by Ingres' 1845 portrait of his sister, the Comtesse d'Haussonville.
Albert approached Ingres around 1850 to undertake the portrait. Ingres dined with the de Broglie family in January 1850, and according to one eye witness, "seemed to be very happy with his model."Although Ingres' main source of income came from portraiture, it distracted from his main interest in history painting, which early in his career, was far less lucrative. He found acclaim in the 1840s, when he became successful enough to no longer depend on commissions. This painting was Ingres' second-last female portrait, and final society portrait.Influenced by the working methods of Jacques-Louis David, Ingres began with a number of nude preparatory sketches, for which he employed professional models. He built up a picture of the sitter's underlying anatomical structure, as seen in the Musee Bonnat study, before deciding on how to build the lavish costume and accessories. Although there is no surviving record of the commissions, and the exact sequence of events is uncertain, the sketches can be dated from 1850, the year the style of her evening dress came into fashion. Ingres signed and dated the final picture at the left center "J. INGRES. pit 1853".Pauline died in 1860 aged 35 from tuberculosis. After her death, Albert published three volumes of her essays on religious history. Albert (who in 1873 became the 28th Prime Minister of France) lived until 1901, but was heartbroken and did not remarry. He kept her portrait for the remainder of his life draped in fabric and hidden behind a velvet curtain, only lending it to select exhibitions. After his own death, the painting passed within the family until 1958 when it was sold to the Metropolitan Museum of Art via the banker and art collector Robert Lehman, and is today held in the Lehman Wing. The family kept most of the jewelry and accessories seen in the painting, although the marabou feathers were sold to the Costume Institute of the Metropolitan Museum.
answer:
What is the full name of the person who bought the portrait of the wife of the man who was heartbroken and did not remarry?
