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: On a beautiful morning in 1923, Clarissa Dalloway sets out from her large house in Westminster to choose the flowers for a party she is holding that evening. Her teenage daughter Elizabeth is unsympathetic, preferring the company of the evangelical Miss Kilman. A passionate old suitor, Peter Walsh, turns up and does not disguise the mess he has made of his career and his love life. For Clarissa this confirms her choice in preferring the unexciting but affectionate and dependable Richard Dalloway. At her party Sally turns up, who was her closest friend, so close they kissed on the lips, but is now wife of a self-made millionnaire and mother of five.
Intercut with Clarissa's present and past is the story of another couple. Septimus was a decorated officer in the First World War but is now collapsing under the strain of delayed shell-shock, in which he is paralysed by horrific flashbacks and consumed with guilt over the death of his closest comrade. His wife Rezia tries to get him psychiatric help but the doctors she consults are little use: when one commits him to a mental hospital, he jumps from a window to his death. The doctor turns up late at Clarissa's party, apologising because he had to attend to a patient's suicide. Clarissa stands by a window and ponders what it would mean to jump. 
Question: What is the first name of the mother of the unsympathetic girl?

Answer: Clarissa.


Question: Passage: Rossier first arrived in Japan in 1859, at a time when early experiments in photography were being conducted in Kyūshū, particularly in Nagasaki. The city was the centre of rangaku, the study of Western science, and it was here that physicians Jan Karel van den Broek and J. L. C. Pompe van Meerdervoort were instrumental in teaching their Japanese students not only medicine but also chemistry and photography. Neither Van den Broek nor Pompe van Meerdervoort was an experienced photographer, and their attempts to produce photographs were largely failures. Nevertheless, in turn they taught wet-collodion process photography to Keisai Yoshio, Furukawa Shumpei, Kawano Teizō, Maeda Genzō, Ueno Hikoma, and Horie Kuwajirō, among others.On his arrival in Japan, Rossier presumably introduced himself as a photographer despatched to Japan by Negretti and Zambra, perhaps thereby inspiring a misconception, for while he remained in the country he was often referred to as an "English" photographer. In Nagasaki, Rossier was assisted in his work by Maeda Genzō, who had been instructed to accompany the "Englishman" and to further learn photography. With Maeda and other students escorting him around the city, Rossier took photographs of priests, beggars, the audience of a sumo match, the foreign settlement, and the group portrait of Alexander von Siebold and samurai. Rossier believed that Pompe van Meerdervoort's failures in photography were due to a lack of the necessary chemicals and so he provided Maeda with a letter of recommendation to procure photographic apparatus and chemicals from a source in Shanghai. Both Maeda and Furukawa bought lenses, chemicals and albumen paper through Rossier.At this time, Ueno Hikoma and Horie Kuwajirō also received photographic instruction from Rossier. Apparently Ueno had originally intended to learn not only the practice of photography but also the manufacture of cameras. The encounter with Rossier seems to have convinced Ueno to pursue photography as a career, but he was so overwhelmed by the technology of the camera that he quickly dropped the notion of making one himself. Within a few months, he and Horie had purchased a French camera and chemicals, thereafter launching their independent photographic careers.Although Rossier's time in Japan was brief and the surviving photographic legacy of his sojourn is scant, he nevertheless had a lasting impact on photography in the country. 
Question: What is the name of the person that nevertheless had a lasting impact on photography in Japan?

Answer:
Rossier.
