In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: Passage: The Steptoes have retired their horse - because the horse is lame, after having to pull the cart (and Harold) home from York, after the horse walked into the back of a removal van which then drove off - and plan to buy a new one with Albert's life savings of £80, putting £9 away for "emergencies". Harold sends Albert home and returns several hours later drunk and introduces Hercules the Second, a short sighted racing greyhound. Harold reveals to Albert that he purchased this from local gangster and loan shark Frankie Barrow for the £80 plus a further £200 owing on top. Furthermore, he plans to pay a small fortune to keep it fed on egg and steak.  
They eventually have to sell all of their possessions to have one final bet on their dog at the races to try to pay off the money they owe. When their dog loses, they just about lose hope when Albert brings up that he had saved £1,000 in a life insurance policy. Harold then schemes to get the money from his father by faking his death. They find an old mannequin among their collection of junk and fit it around Albert's body. They then call Dr. Popplewell, a known alcoholic doctor, who's drunk at the time of seeing Albert and he announces that Albert has died. Harold then brings home a coffin that he has been saving for the inevitable day that his father would actually die. 
Question: What is the name of the entity that Harold plans to feed eggs and steak?
[EX A]: Hercules the Second.

[EX Q]: Passage: Nicholas Rodney Drake (19 June 1948 – 25 November 1974) was an English singer-songwriter and musician known for his acoustic guitar-based songs. He failed to find a wide audience during his lifetime, but his work has since achieved wider recognition.Drake signed to Island Records when he was 20, while a student at the University of Cambridge, and released his debut album, Five Leaves Left, in 1969. By 1972, he had recorded two more albums, Bryter Layter and Pink Moon. Neither sold more than 5,000 copies on initial release. His reluctance to perform live or give interviews contributed to his lack of commercial success. No footage of the adult Drake has been released, only still photographs.Drake is believed to have suffered from depression, reflected in his lyrics. After making Pink Moon, he withdrew from performance and recording, retreating to his parents' home in rural Warwickshire. At the age of 26, Drake died from an overdose of approximately 30 amitriptyline pills, a prescribed antidepressant. His cause of death was determined as suicide.The 1979 release of the retrospective album Fruit Tree triggered a reassessment of Drake's music. By the mid-1980s, he was credited as an influence by such artists as Robert Smith, David Sylvian, and Peter Buck. In 1985, the Dream Academy reached the UK and US charts with "Life in a Northern Town", a song written for and dedicated to Drake. By the early 1990s, he had come to represent a "doomed romantic" musician in the UK music press. The first Drake biography was published in 1997, followed in 1998 by the documentary film A Stranger Among Us. In 1999, his song "Pink Moon" was used in a Volkswagen commercial, resulting in an increase in his U.S. album sales. By 2014, more than 2.4 million Nick Drake albums had been sold in the UK and the US. 
Question: What is the last name of the person whose work has received wider recognition after his death?
[EX A]: Drake.

[EX Q]: Passage: Whales are known to teach, learn, cooperate, scheme, and grieve. The neocortex of many species of whale is home to elongated spindle neurons that, prior to 2007, were known only in hominids. In humans, these cells are involved in social conduct, emotions,  judgement, and theory of mind. Whale spindle neurons are found in areas of the brain that are homologous to where they are found in humans, suggesting that they perform a similar function.
Brain size was previously considered a major indicator of the intelligence of an animal. Since most of the brain is used for maintaining bodily functions, greater ratios of brain to body mass may increase the amount of brain mass available for more complex cognitive tasks. Allometric analysis indicates that mammalian brain size scales at approximately the ⅔ or ¾ exponent of the body mass. Comparison of a particular animal's brain size with the expected brain size based on such allometric analysis provides an encephalisation quotient that can be used as another indication of animal intelligence. Sperm whales have the largest brain mass of any animal on earth, averaging 8,000 cubic centimetres (490 in3) and 7.8 kilograms (17 lb) in mature males, in comparison to the average human brain which averages 1,450 cubic centimetres (88 in3) in mature males. The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans.Small whales are known to engage in complex play behaviour, which includes such things as producing stable underwater toroidal air-core vortex rings or "bubble rings". There are two main methods of bubble ring production: rapid puffing of a burst of air into the water and allowing it to rise to the surface, forming a ring, or swimming repeatedly in a circle and then stopping to inject air into the helical vortex currents thus formed. They also appear to enjoy biting the vortex-rings, so that they burst into many separate bubbles and then rise quickly to the surface. Some believe this is a means of communication. Whales are also known to produce bubble-nets for the purpose of foraging.
Larger whales are also thought, to some degree, to engage in play. The southern right whale, for example, elevates their tail fluke above the water, remaining in the same position for a considerable amount of time. This is known as "sailing". It appears to be a form of play and is most commonly seen off the coast of Argentina and South Africa. Humpback whales, among others, are also known to display this behaviour. 
Question: What type of behavior by whales do some believe is a form of communication?
[EX A]:
biting the vortex-rings.
