[EX Q]: Question: How many times was the person who sent 15,000 troops married? Passage:Halleck's plan, finalized in January 1864, called for Banks to take 20,000 troops up from New Orleans to Alexandria, including the 47th Pennsylvania Infantry, the only regiment from the Keystone State to fight in this campaign, on a route up the Bayou Teche (in Louisiana, the term bayou is used to refer to a slow moving river or stream), where they would be met by 15,000 troops sent down from Major General William T. Sherman's forces in Vicksburg, Mississippi, and under the command of Brigadier General A.J. Smith. Smith's forces were available to Banks only until the end of April, when they would be sent back east where they were needed for other Union military actions. Banks would command this combined force of 35,000, which would be supported in its march up the Red River towards Shreveport by Union Navy Rear Admiral David Dixon Porter's fleet of gunboats. At the same time, 7,000 Union troops from the Department of Arkansas under the command of Major General Frederick Steele would be sent south from Arkansas to rendezvous with Banks in his attack on Shreveport, and to serve as the garrison for that city after its capture.

[EX Q]: Question: Who did Manuel's uncle run against for the mayorship of Ciales? Passage:Natal was born into a family with strong ties to the local politics. His maternal uncle, Javier Albelo Matos, served as a candidate for the mayorship of Ciales the 2000 general election, while his paternal grandfather was an activist for the Partido Popular Democratico (PPD). He studied at Colegio Espíritu Santo in Hato Rey, where he was president of the Student Council. Natal obtained a bachelor's degree from Cornell University in 2008, where he was president of the Puerto Rican Student Association. He did not expect to be accepted by the institution, having applied to study in it as a protocolary measure. When the acceptance letter was received, Natal was surprised and this event triggered a period of adaptation. He offered a speech at his graduation in his role of class president. After returning to Puerto Rico, Natal received a juris doctor from the University of Puerto Rico School of Law in 2011, also serving as president of the student council during his tenure. After graduating from Cornell, Natal became a key figure in a series of strikes held at the University of Puerto Rico in protest of a quota being introduced to the students. Consequently he became involved with the Popular Democratic Party and participated in an internal election for the presidency of the party's National Youth organization. After completing his juris doctor Natal opened his own lawfirm and worked for Charlie Hernández and Luis Vega Ramos, prominent members of the free association movement. In 2013, Natal was named director of the House of Representatives of Puerto Rico Commission on the Judiciary.

[EX Q]: Question: How old was Lhazang Khan when the regent resigned? Passage:About this time, some Dzungars informed the Kangxi Emperor that the 5th Dalai Lama had long since died. He sent envoys to Lhasa to inquire. This prompted Sangye Gyatso to make Tsangyang Gyatso the 6th Dalai Lama public. He was enthroned in 1697. Tsangyang Gyatso enjoyed a lifestyle that included drinking, the company of women, and writing love songs. In 1702, he refused to take the vows of a Buddhist monk. The regent, under pressure from the Emperor and Lhazang Khan of the Khoshut, resigned in 1703. In 1705, Lhazang Khan used the sixth Dalai Lama's escapades as excuse to take control of Lhasa. The regent Sanggye Gyatso, who had allied himself with the Dzungar Khanate, was murdered, and the Dalai Lama was sent to Beijing. He died on the way, near Kokonor, ostensibly from illness but leaving lingering suspicions of foul play. Lhazang Khan appointed a new Dalai Lama who, however, was not accepted by the Gelugpa school. Kelzang Gyatso was discovered near Kokonor and became a rival candidate. Three Gelug abbots of the Lhasa area appealed to the Dzungar Khanate, which invaded Tibet in 1717, deposed Lhazang Khan's pretender to the position of Dalai Lama, and killed Lhazang Khan and his entire family. The Dzungars proceeded to loot, rape and kill throughout Lhasa and its environs. They also destroyed a small force in the Battle of the Salween River which the Emperor had sent to clear traditional trade routes.
