Question: Passage: The United States Exploring Expedition led by Lieutenant Charles Wilkes was tasked with a vast survey of the Pacific Ocean starting in 1838. In September 1840 they arrived in Honolulu, where repairs to the ships took longer than expected. Wilkes decided to spend the winter in Hawaii and take the opportunity to explore its volcanoes while waiting for better weather to continue the expedition. King Kamehameha III assigned American medical missionary Dr. Gerrit P. Judd to the expedition as a translator.Wilkes sailed to Hilo on the island of Hawaiʻi and decided to climb Mauna Loa first, since it looked easier than Mauna Kea. On December 14 he hired about 200 porters, but after he left he realized only about half the equipment had been taken, so he had to hire more Hawaiians at higher pay. When they reached Kīlauea after two days, their guide Puhano headed off to the established ʻAinapō Trail. Wilkes did not want to head back downhill so he blazed his own way through dense forest directed by a compass. The Hawaiians were offended by the waste of sacred trees which did not help morale. At about 6,000 feet (1,800 m) elevation they established a camp called "Sunday Station" at the edge of the forest.
Two guides joined them at Sunday Station: Keaweehu, "the bird-catcher" and another whose Hawaiian name is not recorded, called "ragsdale". Although Wilkes thought he was almost to the summit, the guides knew they were less than halfway up. Since there was no water at Sunday Station, porters had to be sent back ten miles (16 km) to a lava tube on ʻAinapō Trail which had a known supply. After an entire day replenishing stocks, they continued up to a second camp they called "Recruiting Station" at about 9,000 feet (2,700 m) elevation. After another full day's hike they established "Flag Station" on December 22, and by this time were on the ʻAinapō Trail. Most of the porters were sent back down to get another load. 
Question: What is the name of the third station that was established on the hike by United States Exploring Expedition?

Answer: Flag Station.


Question: 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?

Answer: Ferrier.


Question: Passage: From 1837, Alkan lived in the Square d'Orléans in Paris, which was inhabited by numerous celebrities of the time including Marie Taglioni, Alexandre Dumas, George Sand, and Chopin. Chopin and Alkan were personal friends and often discussed musical topics, including a work on musical theory that Chopin proposed to write. By 1838, at 25 years old, Alkan had reached a peak of his career. He frequently gave recitals, his more mature works had begun to be published, and he often appeared in concerts with Liszt and Chopin. On 23 April 1837 Alkan took part in Liszt's farewell concert in Paris, together with the 14-year-old César Franck and the virtuoso Johann Peter Pixis. On 3 March 1838, at a concert at the piano-maker Pape, Alkan played with Chopin, Zimmerman, and Chopin's pupil Adolphe Gutmann in a performance of Alkan's transcription, now lost, of two movements of Beethoven's Seventh Symphony for two pianos, eight hands.At this point, for a period which coincided with the birth and childhood of his natural son, Élie-Miriam Delaborde (1839–1913), Alkan withdrew into private study and composition for six years, returning to the concert platform only in 1844.  Alkan neither asserted nor denied his paternity of Delaborde, which, however, his contemporaries seemed to assume. Marmontel wrote cryptically in a biography of Delaborde that "[his] birth is a page from a novel in the life of a great artist". Alkan gave early piano lessons to Delaborde, who was to follow his natural father as a keyboard virtuoso.Alkan's return to the concert platform in 1844 was greeted with enthusiasm by critics, who noted the "admirable perfection" of his technique, and lauded him as "a model of science and inspiration", a "sensation" and an "explosion". They also commented on the attending celebrities including Liszt, Chopin, Sand and Dumas. In the same year he published his piano étude Le chemin de fer, which critics, following Ronald Smith, believe to be the first representation in music of a steam engine. Between 1844 and 1848 Alkan produced a series of virtuoso pieces, the 25 Préludes Op. 31 for piano or organ, and the sonata Op. 33 Les quatre âges. Following an Alkan recital in 1848, the composer Giacomo Meyerbeer was so impressed that he invited the pianist, whom he considered "a most remarkable artist", to prepare the piano arrangement of the overture to his forthcoming opera, Le prophète. Meyerbeer heard and approved Alkan's arrangement of the overture for four hands (which Alkan played with his brother Napoléon) in 1849; published in 1850, it is the only record of the overture, which was scrapped during rehearsals at the Opéra. 
Question: What is the last name of the composer who invited the man that played with Chopin to prepare a piano arrangement in 1848?

Answer:
Meyerbeer.
