Question: Which opera that Brambilla performed at Teatro Carcano was written first? Passage:After her professional debut in 1831, Brambilla initially sang in several smaller opera houses in northern Italy but in 1833 scored a considerable success at Milan's Teatro Carcano singing Agnese in Bellini's Beatrice di Tenda and the leading soprano role in Fioravanti's Le cantatrici villane. She then appeared on Russia at the Odessa Opera House, which at the time specialised in Italian opera. Upon her return to Milan in 1837, she sang with her sister Marietta at La Scala in the world premiere of In morte di Maria Malibran de Beriot, a cantata in memory of Maria Malibran composed by Gaetano Donizetti, Giovanni Pacini, Saverio Mercadante, Nicola Vaccai and Pietro Antonio Coppola. After singing in Barcelona, she returned to La Scala for the 1839/1840 season in Mercadante's Le due illustri rivali and the world premieres of Mazzucato's I corsari and Coccia's Giovanna II.

question:
Question: How long had the Communist Party of the Soviet Union been in power when Khrushchev gave a speech to the Twentieth Party Congress? Passage:On February 25, 1956, Khrushchev gave a clandestine speech to the Twentieth Party Congress of the Communist Party of the Soviet Union, which was entitled, "On the Cult of Personality and Its Consequences", which denounced Stalin and his proteges. Khrushchev charged Stalin with fostering a personality cult, despite maintaining support for the ideals of communism. The speech was highly critical of Stalin and his reign of terror, primarily denouncing the purges of the Soviet military and Communist Party, which had taken place during the latter part of the 1930s. The speech brought forth several accusations, notably those concerning the Moscow Trials, where rulings were made, based on forced confessions, which were obtained through torture. Judicial decisions were determined, based on liberal interpretations of Article 58 of the Russian SFSR Penal Code, which was introduced in 1927, in order to arrest individuals suspected of counter-revolutionary activities. Due process, in accordance with Soviet law, was often dismissed and replaced with summary proceedings issued by institutional commissions known as NKVD troikas, who issued sentences to the accused without representation, defense, or trial.
