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: Which of the construction materials that St Nicholas was constructed with has a higher value on the Mohs scale? Passage:St Nicholas is constructed in flint, with some conglomerate and brick, and has limestone dressings. The roofs are tiled. Its plan consists of a nave, a chancel with a north vestry (previously a porch), and a west tower. The tower is wholly octagonal. In each face of the upper stage of the tower is a lancet, and there is another lancet on the west side at a lower level. The parapet is battlemented. The tower has a west doorway in Norman style, which has possibly been re-set from elsewhere in the church. It has scalloped capitals, and zig-zag decoration on the arch. Inside the upper part of the tower is a 17th-century dovecote lined with brick nesting boxes. On the south side, between the tower and the nave, is a brick stair turret. The nave windows have two lights with Decorated tracery. Between the windows on the south side is another Norman doorway, again with zig-zag decoration. The north and south walls of the chancel have two-light windows with Y-tracery, and three-light windows with Perpendicular tracery. The east window has five lights. The east gable is decorated with grotesque carvings, and above the east window is head-corbel and a blocked niche. The vestry has two-light north and south windows. In the north wall of the nave is an Early English doorway, with dog-tooth ornament. Around the church are stepped buttresses.
