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.

Question: How many years did the Sacrifice pay-per-view-event happen? Passage:The Impact World Championship is a professional wrestling world championship owned by the promotion Impact Wrestling, formerly Total Nonstop Action Wrestling (TNA). From June 2002 to May 2007, TNA used the NWA World Heavyweight Championship as their primary championship due to an agreement with the National Wrestling Alliance (NWA). On May 13, 2007, the NWA abruptly ended the arrangement and retrieved control of the NWA World Heavyweight Championship. On the same night, TNA were set to host their annual Sacrifice pay-per-view event, in which the NWA World Heavyweight Championship was to be defended by then-champion Christian Cage against Kurt Angle and Sting in a three-way match. Angle won the match and on the following episode of TNA's television program Impact! on May 17, was declared the new TNA World Heavyweight Champion. He was stripped of the championship later in the program, with Management Director Jim Cornette citing a problematic finish to the title match. The ownership of the championship was decided on June 17, 2007 at TNA's Slammiversary event in a King of the Mountain match involving Angle and Cage along with A.J. Styles, Chris Harris and Samoa Joe, which Angle won.
