Example Input: Question: Was the Social Democratic Party around when Knochel was conscripted into the Imperial Army? Passage:Wilhelm Knöchel was born into a Social Democratic working class family in Offenbach, a short distance upriver from Frankfurt. He qualified and worked as a factory machine operator ("Dreher"). In 1917 he was conscripted into the Imperial Army, shortly after which he was badly wounded. There are also references to his having worked as a mines maintenance engineer ("Grubenschlosser"). In 1919, with Germany affected by acute economic hardship and, especially in the cities, a succession of revolutionary uprisings, Knöchel joined the Social Democratic Party ("Sozialdemokratische Partei Deutschlands" / SPD). By 1920 he had relocated in search of work to the industrially vital and internationally critical Ruhr region. Sources differ over whether it was in 1920 or 1923 that he switched to the recently created Communist Party. Between 1924 and 1930 he was a member of the party leadership team for the Dortmund region ("...des Unterbezirk Dortmund"). In 1930, following the death of his first wife, he returned to Offenbach, where it was arranged that his daughter should be brought up by relatives. Knöchel was now employed as a party official.

Example Input: Question: Was the one-sheet Loonie Curling Club located in Canada when Balsdon was a member? Passage:Balsdon skips one of the top teams in Ontario. As of 2019, Balsdon has played in 13 provincial championships. He first played at the provincials in 1999, playing for John Base (4th place). He left the Base rink in 2000 to form his own team. He qualified again in 2002 as a skip, again finishing 4th. His next provincial was the 2005 Ontario Kia Cup, where his rink finished 4th once again. He qualified again in 2007, where he once again finished 4th at the 2007 TSC Stores Tankard. His next provincial in 2011 would be more successful. At the 2011 provincial championship, he lost to the (then) five-time defending champion Glenn Howard rink in the final. At the time, Balsdon represented the one-sheet Loonie Curling Club located in Chaffeys Locks, Ontario, north of Kingston. Despite representing the club, he had only played there once. The Loonie was built in 2008, and Balsdon has represented it twice. Balsdon returned to the Tankard in 2012, finishing tied for 8th. Despite battling an injury for much of the season, Baldson won his first provincial men's title in 2014, when his rink defeated Glenn Howard in the Ontario final. The win broke Howard's record eight-year provincial championship streak. The team was named after third Mark Bice who had skipped the team through zone and regional play due to Baldson recovering from a broken rib. However, Balsdon would skip the team in the provincial championship. The team represented Ontario at the 2014 Tim Hortons Brier, where they went 5-6 in the round robin, missing the playoffs. The following season, at the 2015 Ontario Tankard, Balsdon and his rink lost in a tie breaker. Following the season, the team broke up.
