input: Please answer the following: Given the following context:  Giovanni Battista Barbirolli was born in Southampton Row, Holborn, London, the second child and eldest son of an Italian father and a French mother. He was a British national from birth, and as Southampton Row is within the sound of Bow Bells, Barbirolli always regarded himself as a Cockney. His father, Lorenzo Barbirolli (1864–1929), was a Venetian violinist who had settled in London with his wife, Louise Marie, née Ribeyrol (1870–1962). Lorenzo and his father had played in the orchestra at La Scala, Milan, where they had taken part in the première of Otello in 1887. In London they played in West End theatre orchestras, principally that of the Empire, Leicester Square. The young Barbirolli began to play the violin when he was four, but soon changed to the cello. He later said that this was at the instigation of his grandfather who, exasperated at the child's habit of wandering around while practising the violin, bought him a small cello to stop him from "getting in everybody's way". His education at St. Clement Danes Grammar School overlapped, from 1910, with a scholarship at Trinity College of Music. As a Trinity student, he made his concert debut in a cello concerto in the Queen's Hall in 1911. The following year he won a scholarship to the Royal Academy of Music, which he attended from 1912 to 1916, studying harmony, counterpoint and theory under Dr. J. B. McEwen and the cello with Herbert Walenn. In 1914 he was joint winner of the academy's Charles Rube Prize for ensemble playing, and in 1916 The Musical Times singled him out as "that excellent young 'cello player, Mr Giovanni Barbirolli." The principal of the Academy, Sir Alexander Mackenzie, had forbidden students to play the chamber music of Ravel, which he regarded as "a pernicious influence". Barbirolli was keenly interested in modern music, and he and three colleagues secretly rehearsed Ravel's String Quartet in the privacy of a men's lavatory in the Academy.From 1916 to 1918 Barbirolli was a freelance cellist in London. He recalled, "My first...  answer the following question:  What is the last name of the person who studied harmony, counterpoint, and theory under Dr. J. B. McEwen?

Please answer this: Given the following context:  Like most cats, the jaguar is solitary outside mother–cub groups. Adults generally meet only to court and mate (though limited noncourting socialization has been observed anecdotally) and carve out large territories for themselves. Female territories, which range from 25 to 40 km2 in size, may overlap, but the animals generally avoid one another. Male ranges cover roughly twice as much area, varying in size with the availability of game and space, and do not overlap. The territory of a male can contain those of several females. The jaguar uses scrape marks, urine, and feces to mark its territory.Like the other big cats, the jaguar is capable of roaring and does so to warn territorial and mating competitors away; intensive bouts of counter-calling between individuals have been observed in the wild. Their roar often resembles a repetitive cough, and they may also vocalize mews and grunts. Mating fights between males occur, but are rare, and aggression avoidance behavior has been observed in the wild. When it occurs, conflict is typically over territory: a male's range may encompass that of two or three females, and he will not tolerate intrusions by other adult males.The jaguar is often described as nocturnal, but is more specifically crepuscular (peak activity around dawn and dusk). Both sexes hunt, but males travel farther each day than females, befitting their larger territories. The jaguar may hunt during the day if game is available and is a relatively energetic feline, spending as much as 50–60 percent of its time active. The jaguar's elusive nature and the inaccessibility of much of its preferred habitat make it a difficult animal to sight, let alone study.  answer the following question:  What is the name for the times of day that the jaguar is active?
++++++++
Answer: crepuscular

input question: Given the following context:  The film opens with military veteran helicopter pilot and guide Don Stober flying individuals above the trees of a vast national park. He states that the woods are untouched and remain much as they did during the time when Native Americans lived there. Two female hikers are breaking camp when they are suddenly attacked and killed by an unseen animal. The national park's chief ranger, Michael Kelly, and photographer Allison Corwin, daughter of the park's restaurant owner, decide to follow a ranger to the primitive campsite to check on the female hikers. There, they discover the mangled corpses of the two girls, one of which has been partially buried. At the hospital, a doctor tells Kelly that the girls were killed by a bear. The park supervisor, Charley Kittridge, blames Kelly for the attacks, saying that the bears were supposed to have been moved from the park by Kelly and naturalist Arthur Scott before the tourist season began. Kelly and Kittridge argue over closing the park, before deciding to move all hikers off the park's mountain while allowing campers to remain in the lowlands. Kelly calls Scott, who tells him that all of the bears are accounted for and this specific bear must be unknown to the forest. During a search of the mountain, a female ranger stops for a break at a waterfall. Deciding to soak her feet, she is unaware that the bear is lurking under the falls, and she is attacked and killed. Kelly recruits the helicopter pilot, Stober, to assist in the search. Flying above the forest, they see what they believe to be an animal, only to discover the naturalist Scott adorned in an animal skin while tracking the bear. He informs them that the animal they are looking for is a prehistoric grizzly bear (a fictional Pleistocene-era Arctodus ursos horribilis) standing at least 15 feet tall and weighing 2,000 pounds. Kelly and Stober scoff at the notion.  answer the following question:  What is the last name of the person that helps the park ranger find the naturalist in an animal skin????
output answer:
Stober
