Passage: Axel Nordstrom manages a glass-bottom boat tourist operation in the waters of Santa Catalina Island, California. His widowed daughter, Jennifer Nelson, occasionally helps by donning a mermaid costume and swimming underneath his boat for the passengers' amusement.
One day, Jennifer accidentally meets Bruce Templeton when his fishing hook snags her costume. He reels in the bottom half, leaving the irate Jennifer floating in the water without pants. Jennifer later discovers that Templeton is a top executive at her new place of employment, a NASA aerospace research laboratory in Long Beach, where she works in public relations.
Templeton later recognizes Jennifer at the research laboratory and hires her for a new full-time assignment: to be his biographer and write his life story. His real purpose is to win her affections. There is a problem: the laboratory's security chief, Homer Cripps, after observing her mysterious behavior and curious, code-like phone calls, concludes that Jennifer is a Soviet spy. To prove his suspicions, he has Jennifer put under surveillance by everyone at the lab. When she learns of this, Jennifer sets out to turn the tables on the bumbling Cripps by pretending that she is a spy, a charade that eventually exposes a real spy. 
Question: What is the full name of the character whose daughter occasionally swims in a mermaid costume.?
Axel Nordstrom.

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?
Ferrier.

Passage: The prelude to act 1 combines three recurrent themes: the entry of the bullfighters from act 4, the refrain from the Toreador Song from act 2, and the motif that, in two slightly differing forms, represents both Carmen herself and the fate that she personifies. This motif, played on clarinet, bassoon, cornet and cellos over tremolo strings, concludes the prelude with an abrupt crescendo. When the curtain rises a light and sunny atmosphere is soon established, and pervades the opening scenes. The mock solemnities of the changing of the guard, and the flirtatious exchanges between the townsfolk and the factory girls, precede a mood change when a brief phrase from the fate motif announces Carmen's entrance. After her provocative habanera, with its persistent insidious rhythm and changes of key, the fate motif sounds in full when Carmen throws her flower to José before departing. This action elicits from José a passionate A major solo that Dean suggests is the turning-point in his musical characterisation. The softer vein returns briefly, as Micaëla reappears and joins with José in a duet to a warm clarinet and strings accompaniment. The tranquillity is shattered by the women's noisy quarrel, Carmen's dramatic re-entry and her defiant interaction with Zuniga. After her beguiling "Seguidilla" provokes José to an exasperated high A sharp shout, Carmen's escape is preceded by the brief but disconcerting reprise of a fragment from the habanera. Bizet revised this finale several times to increase its dramatic effect.
Act 2 begins with a short prelude, based on a melody that José will sing offstage before his next entry. A festive scene in the inn precedes Escamillo's tumultuous entrance, in which brass and percussion provide prominent backing while the crowd sings along. The quintet that follows is described by Newman as "of incomparable verve and musical wit". José's appearance precipitates a long mutual wooing scene; Carmen sings, dances and plays the castanets; a distant cornet-call summoning José to duty is blended with Carmen's melody so as to be barely discernible. A muted reference to the fate motif on an English horn leads to José's "Flower Song", a flowing continuous melody that ends pianissimo on a sustained high B-flat. José's insistence that, despite Carmen's blandishments, he must return to duty leads to a quarrel; the arrival of Zuniga, the consequent fight and José's unavoidable ensnarement into the lawless life culminates musically in the triumphant hymn to freedom that closes the act. 
Question: What was the name of the person that shattered the tranquil sounds of the duet?

Carmen.
