Input: Consider Input: 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?

Output: Ferrier.


Input: Consider Input: Passage: The story begins with a view of the city, lowering to a view of the ground underneath.  Deep under the docks, several large wires are connected to the bedrock.  Following the wires away from the coast along the ocean floor, it is shown that they all converge in a strange underwater capsule.  An elevator-like object emerges from the top and rises to an abandoned fishing house infested with rats.  A man exits the elevator and heads toward the city in a motorboat.

Later, at the Daily Planet, a Native American man warns Lois Lane, Clark Kent, and Perry White that they must run a report that Manhattan belongs to his people and should be given back to them.  The Planet crew judges him to be crazy, and his threats to be empty... at least, everyone but Lois, who follows him to his motorboat.  Hiding in the back, Lois is taken to the deserted fishing house on the water and sees his elevator.  The man catches her watching him in the elevator's reflection, and calmly invites her to follow him, promising an amazing story.  Lois follows.
The elevator lowers into the underwater capsule, and the man offers her a seat, then pushes a button which pins her arms and legs to the chair.  Stepping up to the controls, he starts up his earthquake machine, sending a powerful surge of electricity through one of the wires and into the bedrock under the city.  The large explosion causes the entire city to shake, and runs a large crack through the Daily Planet building.  Clark takes advantage of the commotion to change into his Superman costume.
In one leap, Superman dives into the ocean and notices the several wires embedded in the rock.  He pulls one of them out only to have it explode in his face, flinging him the ground and piling him with bedrock.  He pushes the rock away and pulls at a few more, only to have the wires writhe with electric current and wind around him.  At one point, Superman comes up for air only to have one of the wires wind around his neck and pull him down. 
Question: What are the names of the two people of the Planet crew who judge the Native American man as crazy?

Output: Clark Kent.


Input: Consider Input: Passage: The party turned for home after 73 days' southward travel. Rations had been cut several times to extend the return journey time beyond the original 110-day estimate. Shackleton now aimed to reach Hut Point in 50 days, since according to Shackleton's prior orders Nimrod, having returned to take the expedition home, would depart on 1 March at the latest. The four men were now much weakened, yet in the following days they achieved impressive distances, reaching the head of the glacier on 19 January. As they began the descent they had five days' food at half rations, to last them until the Lower Glacier depot; during the ascent the same distance had taken 12 days. Shackleton's physical condition was by now a major concern, yet according to Adams "the worse he felt, the harder he pulled".The depot was reached on 28 January. Wild, ill with dysentery, was unable to pull or to eat anything but biscuits, which were in short supply. On 31 January Shackleton forced his own breakfast biscuit on Wild, a gesture that moved Wild to write: "BY GOD I shall never forget. Thousands of pounds would not have bought that one biscuit". A few days later, the rest of the party were struck with severe enteritis, the result of eating tainted pony-meat. But the pace of march had to be maintained; the small amounts of food carried between depots would make any delay fatal. However, a strong wind behind them enabled them to set a sail on the sledge and maintain a good marching rate.
"We are so thin that our bones ache as we lie on the hard snow", wrote Shackleton. From 18 February onward they began to pick up familiar landmarks, and on the 23rd they reached Bluff Depot, which to their great relief had been copiously resupplied by Ernest Joyce. The range of delicacies over and above the crates of regular supplies was listed by Shackleton: "Carlsbad plums, eggs, cakes, plum pudding, gingerbread and crystallised fruit". Wild's laconic comment was "Good old Joyce".Their food worries were now resolved, but they still had to get back to Hut Point before the 1 March deadline. The final leg of their march was interrupted by a blizzard, which held them in camp for 24 hours. On 27 February, when they were still 33 nautical miles (61 km; 38 mi) from safety, Marshall collapsed. Shackleton then decided that he and Wild would make a dash for Hut Point in hopes of finding the ship and holding her until the other two could be rescued. They reached the hut late on 28 February. Hoping that the ship was nearby, they sought to attract its attention by setting fire to a small wooden hut used for magnetic observations. Shortly afterwards Nimrod, which had been anchored at the Glacier Tongue, came into view: "No happier sight ever met the eyes of man", wrote Wild later. It was a further three days before Adams and Marshall could be picked up from the Barrier, but by 4 March the whole southern party was aboard and Shackleton was able to order full steam towards the north. 
Question: What is the name of the person that "the worse he felt, the harder he pulled"?


Output: Shackleton.
