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.
question:
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.
answer:
Who comes under the tutelage of a math genius teacher?


question:
Passage: Amundsen was born in Fredrikstad (around 80 km from Christiania (now Oslo)), Norway, in 1872, the son of a ship-owner. In 1893, he abandoned his medical studies at Christiania University and signed up as a seaman aboard the sealer Magdalena for a voyage to the Arctic. After several further voyages he qualified as a second mate; when not at sea, he developed his skills as a cross-country skier in the harsh environment of Norway's Hardangervidda plateau. In 1896, inspired by the polar exploits of his countryman Fridtjof Nansen, Amundsen joined the Belgian Antarctic Expedition as mate, aboard Belgica under Adrien de Gerlache. Early in 1898 the ship became trapped by pack ice in the Bellinghausen Sea, and was held fast for almost a year. The expedition thus became, involuntarily, the first to spend a complete winter in Antarctic waters, a period marked by depression, near-starvation, insanity, and scurvy among the crew. Amundsen remained dispassionate, recording everything and using the experience as an education in all aspects of polar exploration techniques, particularly aids, clothing and diet.Belgica's voyage marked the beginning of what became known as the Heroic Age of Antarctic Exploration, and was rapidly followed by expeditions from the United Kingdom, Sweden, Germany and France. However, on his return to Norway in 1899, Amundsen turned his attention northwards. Confident in his abilities to lead an expedition, he planned a traversal of the Northwest Passage, the then-uncharted sea route from the Atlantic to the Pacific through the labyrinth of north Canadian islands. Having earned his master's ticket, Amundsen acquired a small sloop, Gjøa, which he adapted for Arctic travel. He secured the patronage of King Oscar of Sweden and Norway, the support of Nansen, and sufficient financial backing to set out in June 1903 with a crew of six. The voyage lasted until 1906 and was wholly successful; the Northwest Passage, which defeated mariners for centuries, was finally conquered. At the age of 34 Amundsen became a national hero, in the first rank of polar explorers.In November 1906 the American Robert Peary returned from his latest unsuccessful quest for the North Pole, claiming a new Farthest North of 87° 6′—a record disputed by later historians. He immediately began raising funds for a further attempt. In July 1907 Dr Frederick Cook, a former shipmate of Amundsen's from Belgica, set off northwards on what was ostensibly a hunting trip but was rumoured to be an attempt on the North Pole. A month later Ernest Shackleton's Nimrod Expedition sailed for Antarctica, while Robert Falcon Scott was preparing a further expedition should Shackleton fail. Amundsen saw no reason to concede priority in the south to the British, and spoke publicly about the prospects of leading an Antarctic expedition—although his preferred goal remained the North Pole.
answer:
What was the name of the person who planned a traversal of the Northwest Passage?


question:
Passage: All whales are carnivorous and predatory. Odontocetes, as a whole, mostly feed on fish and cephalopods, and then followed by crustaceans and bivalves. All species are generalist and opportunistic feeders. Mysticetes, as a whole, mostly feed on krill and plankton, followed by crustaceans and other invertebrates. A few are specialists. Examples include the blue whale, which eats almost exclusively krill, the minke whale, which eats mainly schooling fish, the sperm whale, which specialize on squid, and the grey whale which feed on bottom-dwelling invertebrates. The elaborate baleen "teeth" of filter-feeding species, mysticetes, allow them to remove water before they swallow their planktonic food by using the teeth as a sieve. Usually whales hunt solitarily, but they do sometimes hunt cooperatively in small groups. The former behaviour is typical when hunting non-schooling fish, slow-moving or immobile invertebrates or endothermic prey. When large amounts of prey are available, whales such as certain mysticetes hunt cooperatively in small groups. Some cetaceans may forage with other kinds of animals, such as other species of whales or certain species of pinnipeds.Large whales, such as mysticetes, are not usually subject to predation, but smaller whales, such as monodontids or ziphiids, are. These species are preyed on by the killer whale or orca. To subdue and kill whales, orcas continuously ram them with their heads; this can sometimes kill bowhead whales, or severely injure them. Other times they corral the narwhals or belugas before striking. They are typically hunted by groups of 10 or fewer orcas, but they are seldom attacked by an individual. Calves are more commonly taken by orcas, but adults can be targeted as well.These small whales are also targeted by terrestrial and pagophilic predators. The polar bear is well adapted for hunting Arctic whales and calves. Bears are known to use sit-and-wait tactics as well as active stalking and pursuit of prey on ice or water. Whales lessen the chance of predation by gathering in groups. This however means less room around the breathing hole as the ice slowly closes the gap. When out at sea, whales dive out of the reach of surface-hunting orcas. Polar bear attacks on belugas and narwhals are usually successful in winter, but rarely inflict any damage in summer.
answer:

What is the overarching name of the broader species that all are generalist and opportunistic feeders?
