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.

Example Input: Passage: Consulting detective Sherlock Holmes fakes his own death in Scotland in order to investigate a number of bizarre apparent suicides that he is convinced are part of an elaborate plot by "a female Moriarty". Returning to his assistant Watson in secret, Holmes notes that all the victims were wealthy gamblers, so disguised as "Rajni Singh", a distinguished Indian officer, he stalks London's gaming clubs.
It is not long before he encounters the villain of the piece, Adrea Spedding. Holmes discovers that she seeks out men short of money, persuades them to pawn their life insurance policies with her accomplices, then kills them. Holmes sets himself up as her next victim, discovering that she uses the deadly spider, Lycosa Carnivora, whose venom causes such excruciating pain that the victims kill themselves. Holmes also finds the footprint of a child nearby.
Searching for evidence Holmes and Watson visit eminent arachnologist Matthew Ordway, who may have supplied the deadly creatures. Holmes soon realizes that the man he is speaking to is an impostor, but the villain makes his escape. Searching the premises, Holmes finds the corpse of the real Ordway, as well as his journals, which allude to something or someone from Central Africa immune to the spider venom. This baffles Holmes until he finds the model skeleton of a child. However, Dr. Watson points out that the relation of the skull and the circumference of the chest prove it is not a child, and Holmes deduces that the Central African thing described in the journal is a pygmy.
Holmes and Watson continue their investigations at a nearby fairground, where Holmes allows himself to fall into the clutches of Spedding and her gang. Bound and gagged, Holmes is tied behind a moving target in a shooting gallery, at which Lestrade and Watson take pot shots with a .22 rifle. However Holmes manages to escape, and Lestrade and the police arrest Spedding, her gang, and the pygmy.
Question: What is the last name of the person who might have given the Lycosa Carnivora to Adrea?
Example Output: Ordway.

Example Input: Passage: In early 1970, Lennon and the Beatles' manager, Allen Klein, turned over the recordings to American producer Phil Spector with the hope of salvaging an album, which was then titled Let It Be. McCartney had become estranged from his bandmates at this time, due to his opposition to Klein's appointment as manager. Several weeks were lost before McCartney replied to messages requesting his approval for Spector to begin working on the recordings. Spector chose to return to the same 26 January recording of "The Long and Winding Road".Spector made various changes to the songs. His most dramatic embellishments occurred on 1 April 1970, the last ever Beatles recording session, when he added orchestral overdubs to "The Long and Winding Road", "Across the Universe" and "I Me Mine" at Abbey Road Studios. The only member of the Beatles present was Starr, who played drums with the session musicians to create Spector's characteristic "Wall of Sound". Already known for his eccentric behaviour in the studio, Spector was in a peculiar mood that day, according to balance engineer Peter Bown: "He wanted tape echo on everything, he had to take a different pill every half hour and had his bodyguard with him constantly. He was on the point of throwing a wobbly, saying 'I want to hear this, I want to hear that. I must have this, I must have that.'" The orchestra became so annoyed by Spector's behaviour that the musicians refused to play any further; at one point, Bown left for home, forcing Spector to telephone him and persuade him to come back after Starr had told Spector to calm down.Spector succeeded in overdubbing "The Long and Winding Road", using eight violins, four violas, four cellos, three trumpets, three trombones, two guitars, and a choir of 14 women, which makes 38 musicians altogther. The orchestra was scored and conducted by Richard Hewson, a young London arranger who had worked with Apple artists Mary Hopkin and James Taylor. This lush orchestral treatment was in direct contrast to the Beatles' stated intentions for a "real" recording when they began work on Get Back.On 2 April, Spector sent each of the Beatles an acetate of the completed album with a note saying: "If there is anything you'd like done to the album, let me know and I'll be glad to help ... If you wish, please call me about anything regarding the album tonight." All four of the band members sent him their approval by telegram.
Question: What is the full name of the person that made dramatic embellishments on 1 April 1970?
Example Output: Phil Spector.

Example Input: 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 or 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 is it called when a whale elevates their tail fluke above the water, remaining in the same position for a considerable amount of time?
Example Output:
sailing.
