Example Input: Question: How many siblings did Khalid have in total? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

Example Input: Question: In which city did Jim Matheson get his first job post graduation? Passage:Matheson was born on April 7, 1949 in Winnipeg, Manitoba to Jack and Peggy Matheson. Matheson had an intention to follow the footsteps of his father, Jack, a long-time sports editor for the Winnipeg Tribune. He graduated from the University of Manitoba with a degree in political science, and while in school, worked a part-time night shift with the Tribune. He got his first job upon completing school with the Regina Leader-Post, but moved west to Edmonton, Alberta six months later. Upon moving to Edmonton, Matheson got a job with the Edmonton Journal in 1970. He initially covered local curling and university sports, but quickly switched to hockey, when, in 1973, Edmonton was granted a WHA franchise, the Edmonton Oilers. Matheson became the beat writer for the Oilers then, and continued when the Oilers joined the NHL in 1979. He spent countless hours covering the team and its five Stanley Cups, and completed more than 300 stories per winter. In addition to writing, Matheson also was a part of the CFRN radio broadcasting team that covered the Oilers. After 24 years, he completed his tenure as beat writer for the Oilers in 1997. He now continues to write for the Edmonton Journal covering the NHL and the Oilers.
