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.

Q: Passage: While no cohesive plot is apparent from the vignette style of the trailer, it can be pieced together that Batman has been murdered, and his killer remains at large. Dick Grayson is long since retired from his superhero days and raising a family with to his wife Barbara Gordon. After his former mentor's death, however, he decides to resume his crime-fighting days as Robin. Remarkably, Grayson does not take up the Nightwing identity. The filmmakers said they chose this because many people outside the comic book community are unfamiliar with Nightwing and they wanted to appeal to a wider audience.Commissioner Gordon is aware of Grayson's secret identity and assists him by supplying official documents. In addition, Gordon provides the voiceover narration at the beginning of the trailer. The head of the investigation into Batman's death is indicated to be Chief O'Hara, a character from the 1960's Batman TV series, who apparently also knows Grayson's identity (noting that Grayson's "crimefighting days are over") His role is suspicious since he strongly wants Grayson to not become involved, even to the point of aligning with Selina Kyle/Catwoman to eliminate Robin and shouting at reporter Clark Kent that he wants "him [presumably Grayson] out of the equation!" O'Hara is also seen rolling up his sleeves, preparing to assault an angry captive Gordon.

Grayson is aware of Superman's secret identity; he addresses him as "Clark". Superman apparently is also motivated (obviously from O'Hara) to discourage Grayson's return to crimefighting and three angry confrontations between the characters are shown, in and out of costume. Grayson is also angered to violence by the sight of a Superman comic book, suggesting a strongly negative history between the two. Other comic books also appear of characters from the film, including Wonder Woman and Catwoman. Fiorella used his own comic book collection for this scene.
Question: Who aligns himself with Catwoman to eliminate Robin?

A: Chief O'Hara.

Q: 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?

A: Charles Koechlin.

Q: Passage: Jules Emile Frederic Massenet (French: [yl emil fedeik masn]; 12 May 1842 13 August 1912) was a French composer of the Romantic era best known for his operas, of which he wrote more than thirty. The two most frequently staged are Manon (1884) and Werther (1892). He also composed oratorios, ballets, orchestral works, incidental music, piano pieces, songs and other music.
While still a schoolboy, Massenet was admitted to France's principal music college, the Paris Conservatoire. There he studied under Ambroise Thomas, whom he greatly admired. After winning the country's top musical prize, the Prix de Rome, in 1863, he composed prolifically in many genres, but quickly became best known for his operas. Between 1867 and his death forty-five years later he wrote more than forty stage works in a wide variety of styles, from opera-comique to grand-scale depictions of classical myths, romantic comedies, lyric dramas, as well as oratorios, cantatas and ballets. Massenet had a good sense of the theatre and of what would succeed with the Parisian public. Despite some miscalculations, he produced a series of successes that made him the leading composer of opera in France in the late 19th and early 20th centuries.
Like many prominent French composers of the period, Massenet became a professor at the Conservatoire. He taught composition there from 1878 until 1896, when he resigned after the death of the director, Ambroise Thomas. Among his students were Gustave Charpentier, Ernest Chausson, Reynaldo Hahn and Gabriel Pierne.
By the time of his death, Massenet was regarded by many critics as old-fashioned and unadventurous although his two best-known operas remained popular in France and abroad. After a few decades of neglect, his works began to be favourably reassessed during the mid-20th century, and many of them have since been staged and recorded. Although critics do not rank him among the handful of outstanding operatic geniuses such as Mozart, Verdi and Wagner, his operas are now widely accepted as well-crafted and intelligent products of the Belle Epoque.
Question: What is the last name of the person who studied under Ambroise Thomas?

A:
Massenet.
