[EX Q]: 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, 828832, briefly in 841 and again under Caliph al-Wathiq (r. 842845). 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.

[EX Q]: Question: Who was the first person to hold the position Theodore Sorensen was nominated for? Passage:In the 1976 Republican primary, President Ford faced a challenge from former California Governor Ronald Reagan, who selected Richard Schweiker as his running mate. Though Thurmond backed Reagan's candidacy, he, along with North Carolina Senator Jesse Helms, led efforts to oust Schweiker from the ticket. During the subsequent general election, Thurmond appeared in a campaign commercial for incumbent U.S. President Gerald Ford in his race against Thurmond's fellow Southerner, former Georgia Governor Jimmy Carter. In the commercial, Thurmond said Ford (who was born in Nebraska and spent most of his life in Michigan) "sound[ed] more like a Southerner than Jimmy Carter". After President-elect Carter nominated Theodore C. Sorensen as his choice to become Director of the Central Intelligence Agency, Thurmond expressed reservations and fellow Senator Jake Garn said he believed Thurmond would not vote for the nomination. Sorensen withdrew from consideration days later, before a vote could be had.
