Example Input: Question: Does the country that was governed by The Bogd Khanate border Russia? Passage:The Bogd Khanate of Mongolia was the government of Mongolia (Outer Mongolia) between 1911 and 1919 and again from 1921 to 1924. By the spring of 1911, some prominent Mongolian nobles including Prince Togs-Ochiryn Namnansuren persuaded the Jebstundamba Khutukhtu to convene a meeting of nobles and ecclesiastical officials to discuss independence from the Manchu-led Qing China. On November 30, 1911 the Mongols established the Temporary Government of Khalkha. On December 29, 1911 the Mongols declared their independence from the collapsing Qing Empire following the Xinhai Revolution. They installed as theocratic sovereign the 8th Bogd Gegeen, highest authority of Tibetan Buddhism in Mongolia, who took the title Bogd Khaan or "Holy Ruler". The Bogd Khaan was last khagan of Mongolia. This ushered in the period of "Theocratic Mongolia", also known as the Bogd Khanate.

Example Input: Question: Who is the current head of the government agency other than the Department of Justice that Westinghouse complained about NBC's extortion? Passage:Channel 4 was in danger of losing its NBC affiliation when Westinghouse balked at NBC's initial offer to trade sister stations KYW radio and WPTZ television (now KYW-TV) in Philadelphia in exchange for WTAM-AM-FM and WNBK television (now WKYC-TV) in Cleveland. In response, NBC threatened to pull its programming from both WBZ-TV and WPTZ unless Westinghouse agreed to the trade. The swap was made in February 1956, but Westinghouse immediately complained to the Federal Communications Commission (FCC) and the U.S. Department of Justice about NBC's extortion. The threat reemerged in 1960 after NBC announced it would swap the Philadelphia stations in exchange for a competing Boston outlet, then-CBS affiliate WNAC-TV (channel 7) and its sister radio stations, from RKO General. Approval of the RKO-NBC deal would have potentially made WBZ-TV an ABC affiliate, completing a three-way swap of network affiliations in Boston. However, in 1964, the FCC nullified the NBC-RKO trade and ordered the NBC-Westinghouse swap reversed without NBC realizing any profit on the deal. WBZ-TV retained its NBC affiliation as a result of the canceled sale.
