Task: Question Generation
Input (English): Passage: At that time, a Parisian ballet audience typically consisted of two diverse groups: the wealthy and fashionable set, who would be expecting to see a traditional performance with beautiful music, and a "Bohemian" group who, the poet-philosopher Jean Cocteau asserted, would "acclaim, right or wrong, anything that is new because of their hatred of the boxes". Monteux believed that the trouble began when the two factions   began attacking each other, but their mutual anger was soon diverted towards the orchestra: "Everything available was tossed in our direction, but we continued to play on". Around forty of the worst offenders were ejected—possibly with the intervention of the police, although this is uncorroborated. Through all the disturbances the performance continued without interruption. The unrest receded significantly during Part II, and by some accounts Maria Piltz's rendering of the final "Sacrificial Dance" was watched in reasonable silence. At the end there were several curtain calls for the dancers, for Monteux and the orchestra, and for Stravinsky and Nijinsky before the evening's programme continued.Among the more hostile press reviews was that of Le Figaro's critic, Henri Quittard, who called the work "a laborious and puerile barbarity" and added "We are sorry to see an artist such as M. Stravinsky involve himself in this disconcerting adventure". On the other hand, Gustav Linor, writing in the leading theatrical magazine Comoedia, thought the performance was superb, especially that of Maria Piltz; the disturbances, while deplorable, were merely "a rowdy debate" between two ill-mannered factions. Emile Raudin, of Les Marges, who had barely heard the music, wrote: "Couldn't we ask M. Astruc ... to set aside one performance for well-intentioned spectators? ... We could at least propose to evict the female element". The composer Alfredo Casella thought that the demonstrations were aimed at Nijinsky's choreography rather than at the music, a view shared by the critic Michel-Dimitri Calvocoressi, who wrote: "The idea was excellent, but was not successfully carried out". Calvocoressi failed to observe any direct hostility to the composer—unlike, he said, the premiere of Debussy's Pelléas et Mélisande in 1902. Of later reports that the veteran composer Camille Saint-Saëns had stormed out of the premiere, Stravinsky observed that this was impossible; Saint-Saëns did not attend. Stravinsky also rejected Cocteau's story that, after the performance, Stravinsky, Nijinsky, Diaghilev and Cocteau himself took a cab to the Bois de Boulogne where a tearful Diaghilev recited poems by Pushkin. Stravinsky merely recalled a celebratory dinner with Diaghilev and Nijinsky, at which the impresario expressed his entire satisfaction with the outcome. To Maximilien Steinberg, a former fellow-pupil under Rimsky-Korsakov, Stravinsky wrote that Nijinsky's choreography had been "incomparable: with the exception of a few places, everything was as I wanted it".
Output (English): What is the first initial of the person who didn't believe the story that Cocteau gave about the group taking a cab?
