In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Input: Consider Input: Passage: Massenet was a prolific composer; he put this down to his way of working, rising early and composing from four o'clock in the morning until midday, a practice he maintained all his life. In general he worked fluently, seldom revising, although Le roi de Lahore, his nearest approach to a traditional grand opera, took him several years to complete to his own satisfaction. It was finished in 1877 and was one of the first new works to be staged at the Palais Garnier, opened two years previously. The opera, with a story taken from the Mahabharata, was an immense success and was quickly taken up by the opera houses of eight Italian cities. It was also performed at the Hungarian State Opera House, the Bavarian State Opera, the Semperoper, Dresden, the Teatro Real in Madrid, and the Royal Opera House, Covent Garden, in London. After the first Covent Garden performance, The Times summed the piece up in a way that was frequently to be applied to the composer's operas: "M. Massenet's opera, although not a work of genius proper, is one of more than common merit, and contains all the elements of at least temporary success."This period was an early high point in Massenet's career. He had been made a chevalier of the Legion of Honour in 1876, and in 1878 he was appointed professor of counterpoint, fugue and composition at the Conservatoire under Thomas, who was now the director. In the same year he was elected to the Institut de France, a prestigious honour, rare for a man in his thirties. Camille Saint-Saens, whom Massenet beat in the election for the vacancy, was resentful at being passed over for a younger composer. When the result of the election was announced, Massenet sent Saint-Saens a courteous telegram: "My dear colleague: the Institut has just committed a great injustice". Saint-Saens cabled back, "I quite agree." He was elected three years later, but his relations with Massenet remained cool.Massenet was a popular and respected teacher at the Conservatoire. His pupils included Bruneau, Charpentier, Chausson, Hahn, Leroux, Pierne, Rabaud and Vidal. He was known for the care he took in drawing out his pupils' ideas, never trying to impose his own. One of his last students, Charles Koechlin, recalled Massenet as a voluble professor, dispensing "a teaching active, living, vibrant, and moreover comprehensive". According to some writers, Massenet's influence extended beyond his own students. In the view of the critic Rodney Milnes, "In word-setting alone, all French musicians profited from the freedom he won from earlier restrictions." Romain Rolland and Francis Poulenc have both considered Massenet an influence on Debussy's Pelleas et Melisande; Debussy was a student at the Conservatoire during Massenet's professorship but did not study under him.
Question: What was the full name of one of Massenet's last students?

Output: Charles Koechlin.

Input: Consider Input: Passage: Too Much Too Soon received positive reviews from contemporary critics. Reviewing for Rolling Stone in 1974, Dave Marsh hailed the New York Dolls as the leading hard rock band in the US and noted what he felt was Nolan's competent drumming, Johansen's ability to add depth to his characters, and Thunders's innovative guitar playing. Marsh especially praised his playing on "Chatterbox", calling it "a classic", and believed even the most brazen songs sounded successful because Morton's production highlighted the group's more unrefined musical qualities. Writing for Creem magazine, Christgau said the polished sound reproduction preserved the band's raw qualities, especially in the case of Johansen's vocals and Nolan's drumming, and remarked that Rundgren "should be ashamedShadow Morton has gotten more out of the Dolls than they can give us live on any but their best nights." Robert Hilburn from the Los Angeles Times felt Too Much Too Soon was a better-produced album that proved the band to be "the real thing", calling it the best record of derisive punk rock since Exile on Main St. by the Rolling Stones in 1972. In The New Yorker, Ellen Willis wrote that she learned to appreciate Too Much Too Soon more than New York Dolls after seeing the band perform songs from the former album in concert, particularly "Human Being" and "Puss 'n' Boots", while Ron Ross from Phonograph Record magazine said the group's "easy going ironic sensibility" was expressed "far more amusingly and accessibly" here than on their debut album.Some reviewers were critical of Too Much Too Soon for what they felt was a poorly recorded and overproduced sound. In a negative review for NME, Nick Kent said it sounded cluttered and "shot through with unfulfilled potential", while Circus magazine panned the record as "cut after cut of annoying screeching". It was nonetheless voted the tenth best album of 1974 in the Pazz & Jop, an annual poll of American critics nationwide, published in The Village Voice. Willis, one of the critics polled, listed it as her fifth favorite record of the year. Christgau, the poll's creator and supervisor, named it third best, and in a decade-end list for The Village Voice, he named it the fourth best album of the 1970s. Los Angeles Times critic Richard Cromelin included it in his list of favorite records from the decade and wrote that Morton's production made it slightly better than New York Dolls.
Question: What did Christgau, the poll's creator and supervisor, name third best?

Output: Too Much Too Soon.

Input: Consider Input: Passage: In the years following his recuperation from the heart attack, Bowie reduced his musical output, making only one-off appearances on stage and in the studio. He sang in a duet of his 1971 song "Changes" with Butterfly Boucher for the 2004 animated film Shrek 2.During a relatively quiet 2005, he recorded the vocals for the song "(She Can) Do That", co-written with Brian Transeau, for the film Stealth.
