input question: What is the answer for the question: What were the names of the two people who performed together for more than twenty years? from the following article ?  Other works that followed continued the composer's new-found seriousness, including many settings of Éluard's surrealist and humanist poems. In 1937 he composed his first major liturgical work, the Mass in G major for soprano and mixed choir a cappella, which has become the most frequently performed of all his sacred works. Poulenc's new compositions were not all in this serious vein; his incidental music to the play La Reine Margot, starring Yvonne Printemps, was pastiche 16th-century dance music, and became popular under the title Suite française. Music critics generally continued to define Poulenc by his light-hearted works, and it was not until the 1950s that his serious side was widely recognised.In 1936 Poulenc began giving frequent recitals with Bernac. At the École Normale in Paris they gave the premiere of Poulenc's Cinq poèmes de Paul Éluard. They continued to perform together for more than twenty years, in Paris and internationally, until Bernac's retirement in 1959. Poulenc, who composed 90 songs for his collaborator, considered him one of the "three great meetings" of his professional career, the other two being Éluard and Landowska. In Johnson's words, "for twenty-five years Bernac was Poulenc's counsellor and conscience", and the composer relied on him for advice not only on song-writing, but on his operas and choral music.Throughout the decade, Poulenc was popular with British audiences; he established a fruitful relationship with the BBC in London, which broadcast many of his works. With Bernac, he made his first tour of Britain in 1938. His music was also popular in America, seen by many as "the quintessence of French wit, elegance and high spirits". In the last years of the 1930s, Poulenc's compositions continued to vary between serious and light-hearted works. Quatre motets pour un temps de pénitence (Four Penitential Motets, 1938–39) and the song "Bleuet" (1939), an elegiac meditation on death, contrast with the song cycle Fiançailles pour rire (Light-Hearted Betrothal), which recaptures...???

What is the answer for the question: What two areas lie on either side of Marble Hall? from the following article ?  The final large reception room on the first floor is the Hondecoeter Room (16), so named because of the three huge oil paintings by Melchior d'Hondecoeter (1636–1695), depicting scenes of birds in courtyards, which are fitted into the neo-Carolean panelling. The panelling was introduced to the room by the 3rd Earl Brownlow in 1876, when it was furnished as the principal dining room of the mansion. The room was initially created as a library in 1808 from the upper part of the earlier kitchen which had originally risen two stories. The West staircase (14) was originally a service stairs, and would have been plainer in decor, but by the late nineteenth century it was in regular use by the family.Either side of the Marble Hall, lie the Great Staircase (2) and the Tapestry Room (11), which contains a collection of early eighteenth century Mortlake tapestries. The Great Staircase to the east of the Marble Hall is unusually placed at Belton, as in a house of this period one would expect to find the staircase in the hall. The stairs rise in three flights around the west, north, and east walls to the former Great Dining Room above the Marble Hall. Thus the staircase served as an important state procession link between the three principal reception rooms of the house. The Great Dining Room, now the Library, has been greatly altered and all traces of Carolean decoration removed, first by James Wyatt in 1778 when it was transformed into a drawing room with a vaulted ceiling, and again in 1876, when its use was again changed, this time to a library. The room contains some 6000 volumes, a superb example of book collecting over 350 years. When Lord Tyrconnel died in 1754 a catalogue of his library identified almost 2,300 books. Almost all of these remain in the Belton library today. Rupert Gunnis attributed the carved marble chimneypiece depicting two Roman goddesses to Sir Richard Westmacott.Leading from the Library is the Queen's Room, the former "Best Bed Chamber". This panelled room was redecorated in 1841 for the visit...

Answer: the Great Staircase

Problem: Given the question: What is the answer for the question: What is the last name of the person who was persuaded to be a British delegate to a conference in Buenos Aires? from the following article ?  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...
