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: When was the place founded that the Nobody's Perfect music video was shot in? Passage:Filmed in technicolor format, the music video for "Nobody's Perfect" was shot at Nu Boyana Film studios in Sofia, Bulgaria, on 24 March 2011 and was directed by Emil Nava. The music video premiered on 14 April 2011 in the United Kingdom through Jessie's Vevo channel. The music video is inspired by Lewis Carroll classic tale Alice's Adventures in Wonderland, Jessie J sits in a banquet table similar to the Mad Hatters' tea party. Jessie J is shown in a hall of doors that gives a resemblance to the curious hall in the first chapter of Alice in Wonderland. Jessie J also rolls in tar and appears dressed as the Roman goddess Libertas, who is better known as the robed female figure of the Statue of Liberty, what could be interpreted as Black-and-white dualism. After completing the filming sessions, Jessie J described the video as her favorite done so far.

Input: Consider Input: Question: How long is the roadway that Route 24 intersects in Taunton? Passage:The highway continues at the Rhode Island border at Rhode Island Route 24 and meets Interstate 195 in Fall River. It briefly runs concurrently with I-195 east (for less than a mile), then exits the interstate and travels north, merging with Route 79 at Exit 7 in northern Fall River. Routes 24 and 79 run concurrently northward until Exit 9 (Assonet). At this point, Route 79 exits the freeway and heads northeast. Route 24 continues north, intersecting the northern end of the Taunton-New Bedford Expressway (Route 140) in Taunton, and Interstate 495 in Raynham. The highway continues north through the city of Brockton and into Randolph, where Route 24 ends at a split junction with Interstate 93. This section of I-93 from Braintree to its junction with I-95 is frequently, yet erroneously, referred to by its former designation of Route 128. This designation was removed from I-93 in 1989, when the roadway obtained the additional designation of U.S. Route 1, although this is not shown on exit signs from Route 24. The route is officially 40.9 miles in length, however, mileposts continue up to 41.2 on the Exit 21B ramp to I-93 south.
