Q: Passage: Tchaikovsky was born in 1840 in Votkinsk, a small town in present-day Udmurtia, formerly the Imperial Russian province of Vyatka. A precocious pupil, he began piano lessons at the age of five, and could read music as adeptly as his teacher within three years. However, his parents' passion for his musical talent soon cooled. In 1850, the family decided to send Tchaikovsky to the Imperial School of Jurisprudence in Saint Petersburg. This establishment mainly served the lesser nobility or gentry, and would prepare him for a career as a civil servant. As the minimum age for acceptance was 12, Tchaikovsky was sent by his family to board at the Imperial School of Jurisprudence's preparatory school in Saint Petersburg, 800 miles (1,300 km) from his family home in Alapayevsk. Once Tchaikovsky came of age for acceptance, he was transferred to the Imperial School of Jurisprudence to begin a seven-year course of studies.Music was not a priority at the School, but Tchaikovsky regularly attended the theater and the opera with other students. He was fond of works by Rossini, Bellini, Verdi and Mozart. Piano manufacturer Franz Becker made occasional visits to the School as a token music teacher. This was the only formal music instruction Tchaikovsky received there. From 1855 the composer's father, Ilya Tchaikovsky, funded private lessons with Rudolph Kündinger, a well-known piano teacher from Nuremberg, and questioned Kündinger about a musical career for his son. Kündinger replied that nothing suggested a potential composer or even a fine performer. Tchaikovsky was told to finish his course and then try for a post in the Ministry of Justice.Tchaikovsky graduated on May 25, 1859 with the rank of titular counselor, a low rung on the civil service ladder. On June 15, he was appointed to the Ministry of Justice in Saint Petersburg. Six months later he became a junior assistant and two months after that, a senior assistant. Tchaikovsky remained there for the rest of his three-year civil service career.In 1861, Tchaikovsky attended classes in music theory organized by the Russian Musical Society and taught by Nikolai Zaremba. A year later he followed Zaremba to the Saint Petersburg Conservatory. Tchaikovsky would not give up his Ministry post "until I am quite certain that I am destined to be a musician rather than a civil servant." From 1862 to 1865 he studied harmony, counterpoint and fugue with Zaremba, while Rubinstein taught him instrumentation and composition. In 1863 he abandoned his civil service career and studied music full-time, graduating in December 1865. 
Question: What is the name of the full name of the man that the titular counselor studied under starting in 1861?

A: Nikolai Zaremba.

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: Hearst died in August 1951. The castle remained on the market for the following decade until bought in 1960 by Antonin Besse II, son of the late Sir Antonin Besse, and donated to the founding council of Atlantic College. Besse was a patron and honorary vice-president of the United World Colleges. The idea for an international school arose from a meeting between the educationalist Kurt Hahn, who founded Gordonstoun, and Air Marshal Sir Lawrence Darvall, the commandant of the NATO Defense College. They conceived of a college for 16–19-year-old students drawn from a wide range of nationalities, with the aim of fostering international understanding. With Rear-Admiral Desmond Hoare, the first headmaster, they persuaded Besse that the castle would make a suitable location for the first United World College, which opened in 1962 with fifty-six students.The first rigid-hulled inflatable boat was patented by Hoare at St Donat's in the 1960s. In an act of generosity, Hoare sold the patent for the boat to the Royal National Lifeboat Institution in 1973 for a notional £1; the RNLI's cheque was not cashed and remains at the castle. From 1963 until 2013 the castle hosted an RNLI lifeboat station which was credited with saving ninety-eight lives along the South Wales coast during its period of operation. The college's early years were financially precarious, but major fund-raising efforts led by Sir George Schuster strengthened the financial position in the mid-1960s.The fiftieth anniversary of the college in 2012 was celebrated with a  visit to the site by Queen Noor of Jordan, President of the United World Colleges Foundation. As at 2017, the college was home to 350 students from more than 90 countries. The Hearst Corporation maintains a connection with St Donat's through a sponsorship programme for students at the college. With a history of occupation from its construction in the late 13th century, St Donat's has been described as the oldest continuously inhabited castle in Wales. 
Question: What is the name of the castle that was donated to the founding council of Atlantic College by Antonin Besse II?

A:
St Donat's.
