Question: Passage: In 1947, Walton was presented with the Royal Philharmonic Society's Gold Medal. In the same year he accepted an invitation from the BBC to compose his first opera. He decided to base it on Chaucer's Troilus and Criseyde, but his preliminary work came to a halt in April 1948 when Alice Wimborne died. To take Walton's mind off his grief, the music publisher Leslie Boosey persuaded him to be a British delegate to a conference on copyright in Buenos Aires later that year.
 While there, Walton met Susana Gil Passo (1926–2010), daughter of an Argentine lawyer. At 22 she was 24 years younger than Walton (Alice Wimborne had been 22 years his senior), and at first she ridiculed his romantic interest in her. He persisted, and she eventually accepted his proposal of marriage. The wedding was held in Buenos Aires in December 1948. From the start of their marriage, the couple spent half the year on the Italian island of Ischia, and by the mid-1950s they lived there permanently.Walton's last work of the 1940s was his music for Olivier's film of Hamlet (1948). After that, he focused his attentions on his opera Troilus and Cressida. On the advice of the BBC, he invited Christopher Hassall to write the libretto. This did not help Walton's relations with the Sitwells, each of whom thought he or she should have been asked to be his librettist. Work continued slowly over the next few years, with many breaks while Walton turned to other things. In 1950 he and Heifetz recorded the Violin Concerto for EMI. In 1951 Walton was knighted. In the same year, he prepared an authorised version of Façade, which had undergone many revisions since its premiere. In 1953, following the accession of Elizabeth II he was again called on to write a coronation march, Orb and Sceptre; he was also commissioned to write a choral setting of the Te Deum for the occasion.Troilus and Cressida was presented at Covent Garden on 3 December 1954. Its preparation was dogged by misfortunes. Olivier, originally scheduled to direct it, backed out, as did Henry Moore who had agreed to design the production; Elisabeth Schwarzkopf, for whom the role of Cressida had been written, refused to perform it; her replacement, Magda László, had difficulty mastering the English words; and Sargent, the conductor, "did not seem well acquainted with the score". The premiere had a friendly reception, but there was a general feeling that Hassall and Walton had written an old-fashioned opera in an outmoded tradition. The piece was subsequently staged in San Francisco, New York and Milan during the next year, but failed to make a positive impression, and did not enter the regular operatic repertory. 
Question: What is the name of the piece that was staged in San Francisco, New York and Milan but reportedly failed to make a positive impression?

Answer: Troilus and Cressida.


Question: Passage: Cowboy drifter Jim Garry is summoned by his friend, smooth-talking Tate Riling. Garry rides into an Indian reservation and finds himself in the middle of a conflict between a cattle owner and some homesteaders. He meets cattle owner John Lufton, and eventually his daughters Amy and Carol. The Luftons suspect that Garry is on Riling's side and are initially hostile, especially Amy. Garry readily admits that he is going to work for his friend.
Riling tells Garry that he and Indian agent Jake Pindalest have devised an elaborate scheme to force Lufton into selling his herd cheaply. Pindalest has gotten the government to order Lufton to remove his cattle from the reservation in a week. Meanwhile, Riling has organized the homesteaders into blocking the move, conning them into believing that he is working in their best interests. With no other option, Lufton would have to sell his herd at bargain prices or lose everything. Lufton would never sell to Riling, but he would to a stranger like Garry. Pindalest would then see that the government buys the herd at an inflated price. Garry would get $10,000 for his part in the swindle.
Lufton manages to outsmart Riling and move his herd unimpeded, but Riling and his men stampede and scatter the cattle back onto the reservation. It would take several days to gather the herd, more time than Lufton has before the deadline. Garry becomes disgusted when a man is killed in the stampede, and he switches sides. Amy still does not trust him. She suspects Garry of betraying the contents of a letter to Riling, unaware that Carol is enamored with Riling and is the one passing information to him. Eventually, Amy comes to trust (and fall in love with) Garry, especially after he defends her father from two of Riling's men. 
Question: Who are the people Riling has believing that his is working in their best interest?

Answer: the homesteaders.


Question: Passage: Robert and Cathy Wilson (Robert Donat and Deborah Kerr) are a timid married couple in 1940 London. He is a bookkeeper, she a bored housewife. However, their tedium-filled lives are drastically changed by the war. He enlists in the Royal Navy, while she (against his wishes) joins the Wrens. During the three years the couple are apart, they are transformed, each becoming much more self-confident.
Cathy's assertive new friend, Dizzy Clayton, helps her break out of her shell. She begins going out with Dizzy's cousin, naval architect Richard, who falls in love with her. However, she remains faithful (if unenthusiastically) to her husband.
Meanwhile, Robert toughens up on sea duty and in time becomes a petty officer. His hands are badly burned when his ship is sunk, but he stoically rows in the lifeboat for five days without complaint. He recuperates in a hospital, tended by Elena, a beautiful nurse. On the last night of his stay, he asks her out to dinner. He is attracted to her, but she informs him that she lost her beloved husband only six months earlier, kisses him, and leaves.
Robert and Cathy both receive ten-day leaves, but each dreads being reunited with the dowdy spouse each remembers and being forced back into the dreary life they shared. 
Question: What is the first name of the person who lost her beloved husband only six months earlier?

Answer:
Elena.
