Q: Passage: De Long's party found no immediate sign at their landing-place of any human habitation, and had only a sketchy idea of where they were—Petermann's map provided few useful details. On September 19, having buried their non-essential possessions in a mound marked by a tent pole, they set out in search of settlements. Progress was hampered by the poor physical condition of the men, in particular Eriksen, who was badly affected by frostbite. On September 21 they halted at two empty huts, probably part of a hunting camp, where Alexey raised spirits by shooting a deer to replenish their dwindling food stocks. De Long allowed his exhausted party several days' rest before resuming the march.On September 28 the party found a large hut, with signs of recent occupation–edible food in the store, and moccasin tracks in the snow. When searches in the locality brought no sign of people, De Long decided to move on. By October 4, Eriksen could not continue; the party halted at another abandoned hut where, on October 6, Eriksen died. On October 9, with the condition of several men worsening, De Long decided to send two of the fittest in the group, Nindemann and Noros, to seek help. Ambler was offered the opportunity to go with them, but felt that his duty as a doctor required him to stay with the main body.For the next week De Long's party struggled on, sometimes making barely a mile a day. Although they jettisoned more of their possessions on the way, De Long insisted on carrying his maps and journals. His entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine". A few days later Alexey, the group's principal hunter, shot a ptarmigan which provided soup. But Alexey was weakening, and on October 17 he died.On October 20, trapped by the weather and without supplies, the party came to a final halt. Throughout the march De Long had written up his journal each day, but after October 20 his entries became intermittent, largely limited to terse statements of the dying and the dead. He noted the deaths of Kaak and Lee on October 21, Iverson on the 28th, Dressler on the 29th. His last entry, dated October 30, records the deaths of Boyd and Görtz and ends "Mr Collins dying". 
Question: What is the last name of the person who entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine?"?

A: De Long.

Q: Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.". 
Question: What is the last name of the person who sang with Roy in Mendelssohn's Elijah?

A: Ferrier.

Q: Passage: Teenaged brothers Zach and Gray Mitchell visit Jurassic World, a dinosaur theme park at the original Jurassic Park site on Isla Nublar. Their aunt, Claire Dearing, is the operations manager. Claire assigns her assistant, Zara, as the boys' guide but they soon evade her. Elsewhere on the island, U.S. Navy veteran and ethologist Owen Grady has been training and researching four Velociraptors. Based on the raptors' ability to follow commands, Vic Hoskins, the head of InGen Security, believes the animals can be weaponized, an idea Owen and his assistant Barry strongly oppose.
Prior to its opening, Claire and park owner Simon Masrani inspect the park's newest attraction, Indominus rex, a genetically-engineered dinosaur created by geneticist Dr. Henry Wu. Masrani tasks Owen with evaluating the enclosure. Owen warns Claire the Indominus lacks social skills, making it more dangerous and unpredictable. When it appears the Indominus has escaped, Owen and two park workers enter the enclosure. The Indominus, which can camouflage itself and mask its heat signature, suddenly appears. Owen survives the attack, but it kills the other two men before escaping into the island's interior. Owen tells Masrani to have the Indominus killed; to protect his company's investment, Masrani instead dispatches a specialized unit to subdue it with non-lethal weaponry. After most of the unit is wiped out, Claire orders the evacuation of the island's northern sector. 
Question: What is the full name of the person that tells Simon Masrani to kill Indominus rex?

A:
Owen Grady.
