question:
Passage: With the encouragement of his parents, Ravel applied for entry to France's most important musical college, the Conservatoire de Paris. In November 1889, playing music by Chopin, he passed the examination for admission to the preparatory piano class run by Eugène Anthiome. Ravel won the first prize in the Conservatoire's piano competition in 1891, but otherwise he did not stand out as a student.   Nevertheless, these years were a time of considerable advance in his development as a composer. The musicologist Arbie Orenstein writes that for Ravel the 1890s were a period "of immense growth ... from adolescence to maturity." 
In 1891 Ravel progressed to the classes of Charles-Wilfrid de Bériot, for piano, and Émile Pessard, for harmony. He made solid, unspectacular progress, with particular encouragement from Bériot but, in the words of the musical scholar Barbara L. Kelly, he "was only teachable on his own terms". His later teacher Gabriel Fauré understood this, but it was not generally acceptable to the conservative faculty of the Conservatoire of the 1890s. Ravel was expelled in 1895, having won no more prizes. His earliest works to survive in full are from these student days: Sérénade grotesque, for piano, and "Ballade de la Reine morte d'aimer", a mélodie setting a poem by Roland de Marès (both 1893).Ravel was never so assiduous a student of the piano as his colleagues such as Viñes and Cortot were. It was plain that as a pianist he would never match them, and his overriding ambition was to be a composer. From this point he concentrated on composition. His works from the period include the songs "Un grand sommeil noir" and "D'Anne jouant de l'espinette" to words by Paul Verlaine and Clément Marot, and the piano pieces Menuet antique and Habanera (for four-hands), the latter eventually incorporated into the Rapsodie espagnole. At around this time, Joseph Ravel introduced his son to Erik Satie, who was earning a living as a café pianist. Ravel was one of the first musicians – Debussy was another – who recognised Satie's originality and talent. Satie's constant experiments in musical form were an inspiration to Ravel, who counted them "of inestimable value". 
Question: What are the names of the two colleagues who it was plain that Ravel, as a pianist, would never match?
answer:
Viñes.


question:
Passage: There is considerable uncertainty about the identities of the Grand Dukes of Lithuania between Traidenis' death in 1282 and Vytenis' assumption of power in 1295. This is in part because the two main sources for Lithuanian history in the 13th century, the Hypatian Codex and the Livonian Rhymed Chronicle, end in the early 1290s. In 1285, one chronicle mentions Daumantas as Grand Duke. He attacked the Bishop of Tver and was severely wounded or even killed in the battle. However, that is the only information about him.
The Gediminid dynasty began its ascent in Lithuania during this time with the emergence of its first leader, Butigeidis. In 1289, leading about 8,000 troops, he attacked Sambia. In 1289 the Teutonic Knights built a castle in present-day Sovetsk (Tilsit) and their raids intensified. Butigeidis was the first to build strong castles along the Neman River. He died in 1290 or 1292, and his brother Butvydas (also known as Pukuveras) inherited the crown. Butvydas was the father of Vytenis and probably of Gediminas. During his short reign Butvydas tried to defend the duchy against the Teutonic Knights; he also attacked Masovia, an ally of the knights. His son, Vytenis, advanced to power in 1295 and ended the period of relative instability. His reign marks the transition from the state's establishment to the point at which it was poised for expansion. 
Question: What is the alias of the person that inherited the crown from Butigeidis?
answer:
Pukuveras.


question:
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 is the first name of the person who was brought notoriety as a modernist?
answer:

William.
