Q: Passage: During Leopold's illness performances were impossible, so Wolfgang turned to composition. According to the writer and musician Jane Glover, Wolfgang was inspired to write symphonies after meeting Johann Christian Bach. It is not clear when this meeting occurred, or when Wolfgang first heard J. C. Bach's symphonies, although he had played the older composer's harpsichord works in his May 1764 royal recital. Wolfgang soon completed his Symphony No. 1 in E flat, K. 16, and started his No. 4 in D major, K. 19 (which Zaslaw concludes was more likely composed, or at least completed, in The Hague). The D major symphony has, in Hildesheimer's words, "an originality of melody and modulation which goes beyond the routine methods of his [grown-up] contemporaries". These are Wolfgang's first orchestral writings, although Zaslaw hypothesises a theoretical "Symphony No. 0" from sketches in Wolfgang's musical notebook. Three lost symphonies, identified in the Köchel catalogue of Mozart's works only by their incipits (first few bars of music), may also have originated from the London period. Other works composed by Wolfgang in London include several instrumental sonatas, the jewel of which, according to Hildesheimer, is the C major sonata for piano, four hands, K. 19d. A set of violin sonatas, with extra flute and cello parts, was dedicated to Queen Charlotte at her request, and presented to her with an appropriate inscription in January 1765. Wolfgang also wrote his first vocal works, the motet "God is our Refuge", K. 20, and the tenor aria Va, dal furor portata, K. 21. 
Question: What was the last name of the older composer who Wolfgang played their harpsichord works in his May 1764 royal recital?

A: Bach.

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: Spoiled playboy Bob Merrick's (Rock Hudson) reckless behaviour causes him to lose control of his speedboat. Rescuers send for the nearest resuscitator, located in Dr. Phillips's house across the lake. While the resuscitator is being used to save Merrick, Dr. Phillips suffers a heart attack and dies. Merrick ends up a patient at Dr. Phillips's clinic, where most of the doctors and nurses resent the fact that Merrick inadvertently caused Dr. Phillips's death. 
Helen Phillips, Dr. Phillips's widow, receives a flood of calls, letters, and visitors all offering to pay back loans that Dr. Phillips refused to accept repayment of during his life. Many claimed he refused by saying "it was already used up." Edward Randolph, a famous artist and Dr. Phillips's close friend, explains to Helen what that phrase means. This helps her to understand why her husband left little money, even though he had a very successful practice.
Merrick discovers why everyone dislikes him. He runs from the clinic but collapses in front of Helen's car and ends up back at the hospital, where she learns his true identity. After his discharge, Merrick leaves a party, drunk. Merrick runs off the road and ends up at the home of Edward Randolph, who recognizes him. Randolph explains the secret belief that powered his own art and Dr. Phillips's success.  Merrick decides to try out this new philosophy. His first attempt causes Helen to step into the path of a car while trying to run away from Merrick's advances. She is left blind as a result of this accident.
Merrick soberly commits to becoming a doctor, trying to fulfill Dr. Phillips's legacy. He also has fallen in love with Helen and secretly helps her adjust to her blindness under the guise of being simply a poor medical student, Robby. 
Question: What is the first name of the person who inadvertently caused Dr. Phillip's death?

A:
Bob.
