Example Input: Question: How old was Ali Bey al-Kabir the year that he had a violent confrontation with Uthman Pasha al-Kurji? Passage:Also in 1764, while Uthman was leading the annual Hajj pilgrimage, he had a violent confrontation with Ali Bey al-Kabir, an influential mamluk from Egypt. When Ali Bey was exiled by the governor of Egypt to Gaza (part of Damascus Eyalet) in 1766, Uthman attempted to drive him out. Uthman managed to have his son, Darwish Pasha, appointed as the governor of Sidon in November 1770 and sometime prior to that, had his other son, Muhammad Pasha, appointed as governor of Tripoli. In 1771, Ali Bey, by now the rebellious governor of Egypt, had dispatched an army under commanders Abu al-Dahab and Ismail Bey to subdue Damascus. Together with Zahir, the combined armies of Egypt and Palestine defeated Uthman's army outside of Damascus and Uthman fled north to the city of Homs. The city fell shortly thereafter, although they did not capture the Citadel of Damascus, which was subsequently besieged. However, Abu al-Dahab suddenly withdrew from the area, citing his fears of violating Islamic principles since seizing an Ottoman province was in effect a direct challenge to the authority of the Ottoman sultan, who held the highest religious honor as the caliph of Islam.

Example Input: Question: After the party split into two in 1903, which leader of the resulting parties was born the earliest? Passage:In 1903, the party split into Bolsheviks led by Vladimir Lenin and Mensheviks led by Julius Martov and Lunacharsky sided with the former. In 1907, he attended the International Socialist Congress, held in Stuttgart. When the Bolsheviks in turn split into Lenin's supporters and Alexander Bogdanov's followers in 1908, Lunacharsky supported his brother-in-law Bogdanov in setting up Vpered. Like many contemporary socialists (including Bogdanov), Lunacharsky was influenced by the empirio-criticism philosophy of Ernst Mach and Avenarius. Lenin opposed Machism as a form of subjective idealism and strongly criticised its proponents in his book Materialism and Empirio-criticism (1908). In 1909, Lunacharsky joined Bogdanov and Gorky at the latter's villa on the island of Capri, where they started a school for Russian socialist workers. In 1910, Bogdanov, Lunacharsky, Mikhail Pokrovsky and their supporters moved the school to Bologna, where they continued teaching classes through 1911. In 1913, Lunacharsky moved to Paris, where he started his own Circle of Proletarian Culture.

Example Input: Question: What was the prior position of the Lions' head coach that was named in 2001? Passage:In 2000, Schlesinger played in all 16 games for the fifth time in six NFL seasons and second year as the Lions' starting fullback. His 15 special teams tackles tied for fifth on squad as well. In 2001, the Lions named Marty Mornhinweg head coach and the team moved away from a power rushing attack to the west coast offense. The fullback, in addition to rushing and blocking responsibilities, can also be more involved in the passing game. Schlesinger finished the 2001 season with single-season career highs in rushing attempts (47), rushing yards (154), rushing touchdowns (three), receptions (60), and receiving yards (466). On the year Schlesinger rushed for 16 first downs, the only season of his career he accumulated a double-digit total in the category. For his efforts during the season, he was voted the Chuck Hughes Most Improved Player by teammates and was also voted onto Howie Long's Tough Guy team. He was also named to the 2001 All-Pro Team by Sports Illustrateds Paul Zimmerman and to the College and Pro Football Newsweekly 2001 All-Pro Second Team squad. In 2002, he finished the year with 139 rushing yards and two rushing touchdowns along with 35 receptions for 263 yards. He was an alternate in the 2002 Pro Bowl to starter Mike Alstott. He was also the Detroit Lions recipient of the 2002 Ed Block Courage Award.
