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?

Ex Output:
Troilus and Cressida.

Passage: Bob Weston works for STOP, a scandal magazine whose owner and staff are proud of being regarded as the filthiest rag in America. One of Bob's colleagues has just written an article about Dr. Helen Gurley Brown, a young psychologist and author of the best-selling book Sex and the Single Girl, a self-help guide with advice to single women on how to deal with men. The article raises doubts on her experience with sex and relationships. Helen is very offended, having lost six appointments with patients due to the article discrediting her as a "23 year-old virgin.". Bob wants to follow up by interviewing her, but she refuses.
Bob's friend and neighbor, stocking manufacturer Frank Broderick, is having marriage issues with his strong-willed wife Sylvia, but can't find the time to go to a counselor. Therefore, Bob decides to impersonate Frank and go to Helen as a patient, with the goal of getting close to her in order to gather more information. In exchange, he'll report back to Frank her advice. During their first couple of sessions, Bob acts shy and smitten, and tries to gently seduce Helen. She seems to respond to Bob's courteous advances, all while insisting it's a transfer and that she'll play the role of Sylvia to the benefit of his therapy. After he fakes a suicide attempt, the two of them end up making out in her apartment, with Bob realizing he's actually falling for Helen, which is the reason he still has not written anything about her, prompting an ultimatum from his boss. 
Question: What is the last name of the person Helen pretends to be in therapy sessions?

Ex Output:
Broderick.

Passage: In September 1928 Britten went as a boarder to Gresham's School, in Holt, Norfolk. At the time he felt unhappy there, even writing in his diary of contemplating suicide or running away: he hated being separated from his family, most particularly from his mother; he despised the music master; and he was shocked at the prevalence of bullying, though he was not the target of it. He remained there for two years and in 1930, he won a composition scholarship at the Royal College of Music (RCM) in London; his examiners were the composers John Ireland and Ralph Vaughan Williams and the college's harmony and counterpoint teacher, S P Waddington.Britten was at the RCM from 1930 to 1933, studying composition with Ireland and piano with Arthur Benjamin. He won the Sullivan Prize for composition, the Cobbett Prize for chamber music, and was twice winner of the Ernest Farrar Prize for composition. Despite these honours, he was not greatly impressed by the establishment: he found his fellow-students "amateurish and folksy" and the staff "inclined to suspect technical brilliance of being superficial and insincere". Another Ireland pupil, the composer Humphrey Searle, said that Ireland could be "an inspiring teacher to those on his own wavelength"; Britten was not, and learned little from him. He continued to study privately with Bridge, although he later praised Ireland for "nurs[ing] me very gently through a very, very difficult musical adolescence".Britten also used his time in London to attend concerts and become better acquainted with the music of Stravinsky, Shostakovich and, most particularly, Mahler. He intended postgraduate study in Vienna with Alban Berg, Arnold Schoenberg's student, but was eventually dissuaded by his parents, on the advice of the RCM staff.The first of Britten's compositions to attract wide attention were composed while at the RCM: the Sinfonietta, Op. 1 (1932), the oboe quartet Phantasy, Op. 2, dedicated to Léon Goossens  who played the first performance in a BBC broadcast on 6 August 1933, and a set of choral variations A Boy was Born, written in 1933 for the BBC Singers, who first performed it the following year. In this same period he wrote Friday Afternoons, a collection of 12 songs for the pupils of Clive House School, Prestatyn, where his brother was headmaster. 
Question: What is the name of the person who won a composition scholarship at the Royal College of Music?

Ex Output:

Britten.
