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: What was the population of Norwood the year that Ken Livingstone got elected to represent it? Passage:Born in Lambeth, South London, to a working-class family, Livingstone joined Labour in 1968 and was elected to represent Norwood at the GLC in 1973, Hackney North and Stoke Newington in 1977, and Paddington in 1981. That year, Labour representatives on the GLC elected him as the council's leader. Attempting to reduce London Underground fares, his plans were challenged in court and declared unlawful; more successful were his schemes to benefit women and underprivileged minorities, despite stiff opposition. The mainstream media gave him the moniker "Red Ken" in reference to his socialist beliefs and heavily criticised him for supporting controversial issues like republicanism, LGBT rights, and a United Ireland. Livingstone was a vocal opponent of the Conservative Party government of Prime Minister Margaret Thatcher, which in 1986 abolished the GLC. Elected as MP for Brent East in 1987, he became closely associated with anti-racist campaigns. He unsuccessfully stood for Labour Party leader on a leftist platform in 1992 and 1994, in the latter losing to Tony Blair. Livingstone became a vocal critic of Blair's New Labour project that pushed the party closer to the centre and won the 1997 general election.

question:
Question: What year was the party that Ion Nistor led founded? Passage:In Bukovina, the Romanian nationalist Ion Nistor and his Democratic Union Party seized the opportunity and ran pro-Romanian Ukrainians and Poles as candidates for the 1919 elections. Active on the left side of the spectrum, Constantin Krakalia joined the Socialist Party. In early 1920, he spent time in prison for protesting against the People's Party (PP) government's clampdown on Ukrainian socialism. He ran in the elections of May against Bogatyrets, taking a seat in the Assembly of Deputies, where he demanded a plebiscite over the territorial status of Bukovina and Maramures. The election of November 1922 were held under the watch of National Liberal Party (PNL), which supported centralizing policies. During the race, the incumbent Rusyn Senator Jevhen Kozak was arrested and intimidated. Fearing persecution, Krakalia made his way into the opposition Peasants' Party; the other Ukrainian socialists soon came into contact with the Union for the Liberation of Ukraine, and were either arrested or pushed to leave Romania.
