Question: What year did the composer of Alzira die?

full_context: Document 1: Il trovatore: Il trovatore (] ; Italian for "The Troubadour") is an opera in four acts by Giuseppe Verdi to an Italian libretto largely written by Salvadore Cammarano, based on the play "El trovador" (1836) by Antonio García Gutiérrez. It was Gutiérrez's most successful play, one which Verdi scholar Julian Budden describes as "a high flown, sprawling melodrama flamboyantly defiant of the Aristotelian unities, packed with all manner of fantastic and bizarre incident."
Document 2: Gaetano Fraschini: Gaetano Fraschini (16 February 1816 – 23 May 1887) was an Italian tenor. He created many roles in 19th century operas, including five composed by Giuseppe Verdi. His voice was "heroic ... with a baritonal quality, ... yet Verdi and Donizetti appreciated his ability to sing softly and with subtlety." An Italian biographer has pointed out Fraschini's role in extending the longevity of Donizetti's operas, while at the same time accelerating the ascent of Verdi's repertory. He was indeed the most prominent singer who facilitated the transition from Donizetti to Verdi. Fraschini sang over one hundred roles and Verdi placed him at the top of his favorite tenors' list and described him as a "natural Manrico" for his "Il trovatore". Fraschini also played a pivotal role in the success of many operas by Pacini and Mercadante.
Document 3: Aroldo: Aroldo (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on and adapted from their earlier 1850 collaboration, "Stiffelio". The first performance was given in the Teatro Nuovo Comunale in Rimini on 16 August 1857.
Document 4: Aida: Aida (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Antonio Ghislanzoni. Set in Egypt, it was commissioned by and first performed at Cairo's Khedivial Opera House on 24 December 1871; Giovanni Bottesini conducted after Verdi himself withdrew. Today the work holds a central place in the operatic canon, receiving performances every year around the world; at New York's Metropolitan Opera alone, "Aida" has been sung more than 1,100 times since 1886. Ghislanzoni's scheme follows a scenario often attributed to the French Egyptologist Auguste Mariette, but Verdi biographer Mary Jane Phillips-Matz argues that the source is actually Temistocle Solera.
Document 5: La traviata: La traviata (] , The Fallen Woman) is an opera in three acts by Giuseppe Verdi set to an Italian libretto by Francesco Maria Piave.

His 1890 masterpiece "Cavalleria Rusticana" caused one of the greatest sensations in opera history and single-handedly ushered in the "Verismo" movement in Italian dramatic music. While it was often held that Mascagni, like Leoncavallo, was a "one-opera man" who could never repeat his first success, "L'amico Fritz" and "Iris" have remained in the repertoire in Europe (especially Italy) since their premieres. Mascagni said that at one point, "Iris" was performed in Italy more often than "Cavalleria" (cf. Stivender).
