Q: Passage: Bellette and Haefliger returned to Australia just before the outbreak of World War II. Shortly after her arrival, Bellette held an exhibition at Sydney's Macquarie Galleries. The couple became influential members of the Sydney Art Group, a network of "fashionable" moderns whose membership included William Dobell and Russell Drysdale. Bellette painted and held regular shows – "a solo show every second year and a group show every year at the Macquarie Galleries". Her husband served as art critic for The Sydney Morning Herald for a decade and a half.In 1942, Bellette won the Sir John Sulman Prize with For Whom the Bell Tolls. She won it again in 1944 with her painting Iphigenia in Tauris, inspired by Euripides' play. The composition is set in a dry, open landscape, with several riders on horses whose appearance suggests "the Australian present, rather than Greek antiquity". The judge awarding the prize actually preferred another of her entries, Electra, depicting the sister of Iphigenia also prominent in Greek tragedy – but it failed to meet the size requirements. Both Iphigenia in Tauris and Electra were among the many works created by Bellette in the 1940s that were inspired by the tragedies of Euripides, Sophocles and Homer. Her choice of subject matter and approach placed her at odds with mainstream modernism, while she seemed to shun explicit links between the classical and the Australian. Bellette reasoned that she preferred to choose her palette and the spatial arrangements of her compositions to evoke a place's atmosphere. Critics identified the influence of European modernists Aristide Maillol and Giorgio de Chirico, as well as Italian Quattrocento painters Masaccio and Piero della Francesca, about some of whom Bellette wrote articles in the journal Art in Australia.The most distinctive feature of the artist's work was this choice of classical subjects. In 1946, Bellette's paintings were hung in at least four separate exhibitions. Reviewers commented on her synthesis of "the impulsiveness of romanticism and the deliberateness of classicism", and her "romantically classical" approach. Despite the generally positive views, there were some reservations, particularly that the artist might be at risk of settling upon, and then repeating, a formula in her work. Bellette's treatment of classical subjects extended beyond conventional painting; in 1947 she created a textile design, titled "myths and legends", and in 1948 she created the sets for a production of Shakespeare's Pericles, Prince of Tyre. Her "vigorous imaginativeness" was well reviewed, though the acting was not. 
Question: Whose "vigorous imaginativeness" was commented upon?

A: Bellette.

Q: Passage: Zappa's relationship with long-time manager Herb Cohen ended in 1976. Zappa sued Cohen for skimming more than he was allocated from DiscReet Records, as well as for signing acts of which Zappa did not approve. Cohen filed a lawsuit against Zappa in return, which froze the money Zappa and Cohen had gained from an out-of-court settlement with MGM over the rights of the early Mothers of Invention recordings. It also prevented Zappa having access to any of his previously recorded material during the trials. Zappa therefore took his personal master copies of the rock-oriented Zoot Allures (1976) directly to Warner Bros., thereby bypassing DiscReet.In the mid-1970s Zappa prepared material for Läther (pronounced "leather"), a four-LP project. Läther encapsulated all the aspects of Zappa's musical styles—rock tunes, orchestral works, complex instrumentals, and Zappa's own trademark distortion-drenched guitar solos. Wary of a quadruple-LP, Warner Bros. Records refused to release it. Zappa managed to get an agreement with Phonogram Inc., and test pressings were made targeted at a Halloween 1977 release, but Warner Bros. prevented the release by claiming rights over the material. Zappa responded by appearing on the Pasadena, California radio station KROQ, allowing them to broadcast Läther and encouraging listeners to make their own tape recordings. A lawsuit between Zappa and Warner Bros. followed, during which no Zappa material was released for more than a year. Eventually, Warner Bros. issued different versions of much of the Läther material in 1978 and 1979 as four individual albums (five full-length LPs) with limited promotion.Although Zappa eventually gained the rights to all his material created under the MGM and Warner Bros. contracts, the various lawsuits meant that for a period Zappa's only income came from touring, which he therefore did extensively in 1975–77 with relatively small, mainly rock-oriented, bands. Drummer Terry Bozzio became a regular band member, Napoleon Murphy Brock stayed on for a while, and original Mothers of Invention bassist Roy Estrada joined. Among other musicians were bassist Patrick O'Hearn, singer-guitarist Ray White and keyboardist/violinist Eddie Jobson. In December 1976, Zappa appeared as a featured musical guest on the NBC television show Saturday Night Live. Zappa's song "I'm the Slime" was performed with a voice-over by SNL booth announcer Don Pardo, who also introduced "Peaches En Regalia" on the same airing. In 1978, Zappa served both as host and musical act on the show, and as an actor in various sketches. The performances included an impromptu musical collaboration with cast member John Belushi during the instrumental piece "The Purple Lagoon". Belushi appeared as his Samurai Futaba character playing the tenor sax with Zappa conducting. 
Question: What is the first name of the person who prevented Zappa having access to any of his previously recorded material during the trials?

A: Herb.

Q: Passage: Sir William Turner Walton, OM (29 March 1902 – 8 March 1983) was an English composer. During a sixty-year career, he wrote music in several classical genres and styles, from film scores to opera. His best-known works include Façade, the cantata Belshazzar's Feast, the Viola Concerto, the First Symphony, and the British coronation anthems Crown Imperial and Orb and Sceptre.
Born in Oldham, Lancashire, the son of a musician, Walton was a chorister and then an undergraduate at Christ Church, Oxford. On leaving the university, he was taken up by the literary Sitwell siblings, who provided him with a home and a cultural education. His earliest work of note was a collaboration with Edith Sitwell, Façade, which at first brought him notoriety as a modernist, but later became a popular ballet score.
In middle age, Walton left Britain and set up home with his young wife Susana on the Italian island of Ischia. By this time, he had ceased to be regarded as a modernist, and some of his compositions of the 1950s were criticised as old-fashioned. His only full-length opera, Troilus and Cressida, was among the works to be so labelled and has made little impact in opera houses. In his last years, his works came back into critical fashion; his later compositions, dismissed by critics at the time of their premieres, were revalued and regarded alongside his earlier works.
Walton was a slow worker, painstakingly perfectionist, and his complete body of work across his long career is not large. His most popular compositions continue to be frequently performed in the 21st century, and by 2010 almost all his works had been released on CD. 
Question: What are the last names of the two people who collaborated on Façade?

A:
Walton.
