TASK DEFINITION: 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.
PROBLEM: 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.

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

PROBLEM: Passage: In 1870, 18-year-old Travis Coates is left in charge of his precocious 12-year-old brother, Arliss, on the family farm in Southwest Texas, while their parents visit an ailing grandmother. While Arliss and his dog, Savage Sam, are tracking a bobcat, Travis is warned by Bud Searcy that renegade Apaches are in the area. When Travis joins Bud's 17-year-old daughter, Lisbeth, in a search for Arliss, all three are captured by a band of Apaches led by a Comanche. The boys' Uncle Beck Coates witnesses the scene and manages to wound the Native American leader, but Beck's horse is shot by one of the braves, allowing the Comanche and his followers to escape with the captives. Beck alerts the U. S. Cavalry, but the Native Americans split into three groups and ride for the hills; in the confusion, Travis escapes but is knocked unconscious and left to die. Beck and his posse of five find Travis and his dog, set out in pursuit of the other captives, and eventually find the Indians in a valley fighting over Lisbeth. Although posse member Pack Underwood, bent on revenge for the massacre of his family, fires a shot that alerts the Indians to their planned ambush, the youngsters are saved and the renegades captured.

SOLUTION: What are the first names of Beck Coates' nephews?

PROBLEM: Passage: The Leningrad premiere of Shostakovich's Symphony No. 7 took place on 9 August 1942 during the Second World War, while the city of Leningrad (now St. Petersburg) was under siege by Nazi German forces.
Dmitri Shostakovich had intended the piece to be premiered by the Leningrad Philharmonic Orchestra, but because of the siege, that group was evacuated from the city, as was the composer himself. The world premiere of the symphony was held on 5 March in Kuybyshev with the Bolshoi Theatre Orchestra. The Leningrad premiere was performed by the surviving musicians of the Leningrad Radio Orchestra, supplemented with military performers. Most of the musicians were suffering from starvation, which made rehearsing difficult: musicians frequently collapsed during rehearsals, and three died. The orchestra was able to play the symphony all the way through only once before the concert.
Despite the poor condition of the performers, the concert was highly successful, prompting an hour-long ovation. The concert was supported by a Soviet military offensive, code-named Squall, intended to silence German forces during the performance. The symphony was broadcast to the German lines by loudspeaker as a form of psychological warfare. The Leningrad premiere was considered by music critics to be one of the most important artistic performances of the war because of its psychological and political effects. The conductor concluded that "in that moment, we triumphed over the soulless Nazi war machine". Reunion concerts featuring surviving musicians were convened in 1964 and 1992 to commemorate the event.

SOLUTION:
What was the full name of the person that was evacuated from Leningrad?
