Input: Consider 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.

Input: Consider Input: Question: Which university's football team that Bradford played against after his return had a better 2009 season record? Passage:However, before the season began, Gresham suffered a season-ending injury. During the season opener against BYU, Bradford suffered an injury to his shoulder that forced him to sit out the next several games. The Sooners would go on to lose that game and their fourth game against Miami. Bradford returned for game number five against Baylor, but reinjured his shoulder the next week against Texas, ending his season and giving the Sooners their third loss of the season. The Sooners would continue to suffer many injuries throughout the remainder of the season including losing offensive linemen Jarvis Jones and Brody Eldridge, and defensive players Tom Wort, DeMarcus Granger and Auston English for the season. With freshman Landry Jones now leading the offense, the Sooners would go on win every home game from that point forward, including a season-ending win over in-state rival Oklahoma State, extending their NCAA-leading home winning streak to 30 games. However, the Sooners would also lose all but one of their away games. Oklahoma ended the regular season with seven wins and five losses (5–3 in the Big 12). The game marked Oklahoma's third appearance in the Sun Bowl. They were a perfect 2-0 in their previous games. In 1981, they defeated Houston 40–14, and in 1993, they defeated Texas Tech 41–10.

Input: Consider Input: Question: Who ruled Shinano Province when Enichi-ji sent troops against Kiso Yoshinaka during the Genpei War? Passage:Enichi-ji was opened in 807 by the Hossō sect scholar-monk Tokuitsu, who had come from Nara to spread the faith in the Aizu region. He overcame the followers of the Tendai and Shingon sects to become preeminent in Aizu, and by the time of his death in 842, the temples was a complete Shichidō garan with 300 monks in residence, several thousand sōhei and more than 3500 sub-temples. By the late Heian period, the temple had extended its holdings into eastern Echigo province and had established close ties with the Taira clan. During the Genpei War, the temple sent troops in support of the Heike in Shinano Province against Kiso Yoshinaka. However, the temple's leading general, Jōtan-bō, was killed at the 1181 Battle of Yokotagawa by Yoshinaka's forces, and the temple's forces withdrew and the temple went into decline.
