Example Input: Question: Who is the current office holder of the position that Clinton held from 1977 to 1979? Passage:William Jefferson Clinton (born William Jefferson Blythe III; August 19, 1946) is an American politician who served as the 42nd president of the United States from 1993 to 2001. Prior to his presidency, he served as governor of Arkansas (19791981 and 19831992) and as attorney general of Arkansas (19771979). A member of the Democratic Party, Clinton was known as a New Democrat, and many of his policies reflected a centrist "Third Way" political philosophy. He is the husband of former Secretary of State and former U.S. Senator Hillary Clinton. In 1998, Clinton was impeached by the House of Representatives. The impeachment was based on accusations that Clinton committed perjury and obstruction of justice for the purpose of concealing his affair with Monica Lewinsky, a 22-year-old White House intern. He was acquitted by the Senate and completed his term in office. Clinton is notable as one of only two U.S. presidents (following Andrew Johnson 130 years earlier) to have been impeached.

Example Input: Question: Which of Khalid's two sons outlived the other? 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.
