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 Tögs-Ochiryn Namnansüren 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.

Question: When did the person who overthrew President Momoh achieve the rank he held at the time? Passage:On 29 April 1992, a group of Junior soldiers in the Sierra Leone Army led by a 25 year old Captain Valentine Strasser overthrew President Momoh, and Sierra Leone was under Military rule from 1992 to 1996 during the civil war. Sierra Leone returned to a democratically elected government when the military Junta under Brigadier General Julius Maada Bio who had ousted Strasser in a coup in 1996, handed the presidency to Ahmad Tejan Kabbah of the SLPP after his victory in the 1996 Sierra Leone presidential election. However, on 25 May 1997, the Sierra Leone military overthrew President Kabbah in a coup and Major General Johnny Paul Koroma became the country's Head of State. However, in February 1998, a coalition of West African Ecowas armed forces led by Nigeria reinstated President Kabbah by military force, and the leaders of the coup were executed after they were sentenced to death by a Sierra Leone military court. In January 2002, President Kabbah announced the ending of the civil war with the help and support of Ecowas, the British government, the African Union, and the United Nations. Sierra Leone has had an uninterrupted democratic government from 1998 to present.
