Question: 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.

Question: Question: Which team has more NFC Championship wins, the Green Bay Packers or the Minnesota Vikings? Passage:In his first season in 1997, the 49ers went during the regular season, earning home-field advantage in the playoffs in the National Football Conference (NFC). After defeating the Minnesota Vikings in the divisional round, San Francisco hosted the Green Bay Packers in the NFC Championship Game, but in a muddy, rainy contest at Candlestick Park. The defeat was the 49ers' fourth NFC title loss of the 1990s, following losses to the New York Giants in 1990 and the Dallas Cowboys in 1992 and 1993, and it was their third playoff loss to the Packers in as many seasons. In 1998, the 49ers posted a 12–4 record and returned to the playoffs as a wild-card team, but to the eventual NFC champion Atlanta Falcons. Two losing seasons followed, but in 2001, the 49ers returned to the playoffs after season, once again to be eliminated by the Packers.
