Example Input: 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 Bériot, 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.

Example Input: Question: How many years had Gary Tallon been playing professionally by the year Boulding turned professional? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.

Example Input: Question: Was Laman or Lemuel born first? Passage:Lehi has a vision of the tree of life. Relating this vision to his children, he expounds on it by teaching about the Messiah, and that they need to be righteous. Nephi prays to the Lord for a similar vision and help understanding his father's vision. In his vision, Nephi sees the vision his father had described, and also given an explanation about its symbolism. Nephi is shown many past and future events, including the life of the Son of God. He also sees the civilizations of his descendants, the voyages of Columbus, the American Revolutionary War, the scattering of his descendants (the American Indians), the Book of Mormon, its translation by Joseph Smith, the restoration of God's church, continued revelation in the modern era, and the correction of biblical translation errors. Nephi sees apocalyptic events, but is forbidden to write about them because John the Apostle will write them in the Bible. Finally, Nephi sees the future generations of his descendants, and of his brothers Laman and Lemuel. Whereas his people will have the gospel, they will ultimately be destroyed for wickedness; however the children of his brothers will be raised without a knowledge of the gospel, survive to the modern era, and be taught by the gospel and the restored church.
