Example Input: Question: Is Carl Linnaeus older than the French zoologist who introduced the horned screamer in the genus Anhima? Passage:The horned screamer was described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae. He introduced the binomial name Palamedea cornuta. The horned screamer is now the only species placed in the genus Anhima that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The specific epithet cornuta is the Latin word for "horned". The German naturalist Georg Marcgrave had used the Latin name Anhima in 1648 for the horned screamer in his Historia naturalis Brasiliae. The name was from the word for the bird in the Tupi language of South America.

Example Input: Question: Is the club Charles played against in 1883 still active? Passage:Educated at Wellington College and later attending Trinity Hall, Cambridge, Willock made a single first-class appearance for Cambridge University against the Marylebone Cricket Club at Fenner's in 1883. He was dismissed in Cambridge University's first-innings of 100 for a duck by Wilfred Flowers, while in the Marylebone Cricket Club's first-innings of 159 he took the wickets of Billy Gunn and Percy de Paravicini to finish with figures of 2/18 from 28 overs. In the University's second-innings of 65, he was once again dismissed for a duck by Flowers, while in the Marylebone Cricket Club's successful chase, he dismissed Gunn for a second time. Later that season he made a single first-class appearance for Sussex against Hamshire at Day's Antelope Ground. In Hampshire's first-innings of 110, he bowled ten wicketless overs which conceded 5 runs, while he ended Sussex's first-innings of 94 unbeaten on 8.

Example Input: Question: Who was the mayor of New York City the year Carroll left the city to return to Maryland? Passage:After finishing schooling, Carroll worked as a student lawyer for the law office of Brown and Brune in Baltimore. He was admitted to the bar in 1851. Carroll practiced law in Maryland from 1854 until 1858. He ran as a Howard County Democratic candidate for the state General Assembly in 1854, (shortly after the separation of the former Howard or Western District of Anne Arundel County and the "erection"/establishment of Howard as the 22nd of the state's 23 counties), however losing to his opponent from the newly-dominant "Know Nothing" Party (also known as the American Party) during the political crises of the 1850s. Carroll then moved to New York City and while there, accepted a position as deputy clerk and United States Commissioner in the office of the clerk of the United States District Court. He stayed there until 1861, at the outbreak of the Civil War, when he returned to Maryland, where he then remained the rest of his life. When he returned to Maryland, Carroll purchased the "Doughoregan Manor", historic family estate in Howard County, near Ellicott City from his older brother Charles Carroll.
