Task: Question Answering
Input (English): Passage: The prelude to act 1 combines three recurrent themes: the entry of the bullfighters from act 4, the refrain from the Toreador Song from act 2, and the motif that, in two slightly differing forms, represents both Carmen herself and the fate that she personifies. This motif, played on clarinet, bassoon, cornet and cellos over tremolo strings, concludes the prelude with an abrupt crescendo. When the curtain rises a light and sunny atmosphere is soon established, and pervades the opening scenes. The mock solemnities of the changing of the guard, and the flirtatious exchanges between the townsfolk and the factory girls, precede a mood change when a brief phrase from the fate motif announces Carmen's entrance. After her provocative habanera, with its persistent insidious rhythm and changes of key, the fate motif sounds in full when Carmen throws her flower to José before departing. This action elicits from José a passionate A major solo that Dean suggests is the turning-point in his musical characterisation. The softer vein returns briefly, as Micaëla reappears and joins with José in a duet to a warm clarinet and strings accompaniment. The tranquillity is shattered by the women's noisy quarrel, Carmen's dramatic re-entry and her defiant interaction with Zuniga. After her beguiling "Seguidilla" provokes José to an exasperated high A sharp shout, Carmen's escape is preceded by the brief but disconcerting reprise of a fragment from the habanera. Bizet revised this finale several times to increase its dramatic effect.
Act 2 begins with a short prelude, based on a melody that José will sing offstage before his next entry. A festive scene in the inn precedes Escamillo's tumultuous entrance, in which brass and percussion provide prominent backing while the crowd sings along. The quintet that follows is described by Newman as "of incomparable verve and musical wit". José's appearance precipitates a long mutual wooing scene; Carmen sings, dances and plays the castanets; a distant cornet-call summoning José to duty is blended with Carmen's melody so as to be barely discernible. A muted reference to the fate motif on an English horn leads to José's "Flower Song", a flowing continuous melody that ends pianissimo on a sustained high B-flat. José's insistence that, despite Carmen's blandishments, he must return to duty leads to a quarrel; the arrival of Zuniga, the consequent fight and José's unavoidable ensnarement into the lawless life culminates musically in the triumphant hymn to freedom that closes the act. 
Question: What was the name of the person that shattered the tranquil sounds of the duet?
Output (English): Carmen.
