Example Input: 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.

Example Input: Question: Who managed the team just prior to the current manager? Passage:The 2019–20 season is Port Vale's 108th season of football in the English Football League, and third consecutive season in EFL League Two. It is the first full season under manager John Askey and new owners Carol and Kevin Shanahan. The season covers the period from 1 July 2019 through to 30 June 2020. Askey reshaped the squad by letting 14 players go and bringing in 14 new signings, though David Amoo was the only new player in the starting eleven for the opening game of the season. They lost just one league game in six matches in August, though this was a heavy 5–2 defeat at Grimsby Town, and they also exited the EFL Cup at the first round. September saw them in indifferent form, as they picked up just one league win, though Vale did secure their place in the knockout stages of the EFL Trophy. October saw more promise, as they picked up their first away win, though were held to disappointing draws at home to struggling teams. They went on to claim five wins in six games in the month of November, including a 1–0 victory at local rivals Crewe Alexandra and wins against Milton Keynes Dons and Cheltenham Town in the FA Cup.
