Q: 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.

Q: Question: The architectural style of which the church was built was a popular architectural style in the region for how many years? Passage:The church is constructed in punch-dressed sandstone ashlar, and has slate roofs with inserted skylight windows. Its architectural style is Early English. The plan consists of a four-bay nave without aisles, a two-bay chancel with a north chapel and a south vestry, and a west tower. The tower is in three stages, with clasping buttresses, and contains paired west doorways, a clock face in a diamond-shaped surround, and pairs of louvred bell openings. At the top of the tower is an embattled parapet with octagonal corner pinnacles, and there are more pinnacles at the angles of the nave. The bays of the nave are separated by buttresses, and each bay contains a corbel-table and a pair of lancet windows. The sides of the chancel also contain paired lancet windows, and the east window consists of a triple stepped lancet in a blank arch. The north chapel is gabled, and contains a wheel window. The interior has been remodelled, but originally it contained a three-sided gallery on cast iron columns.

Q: Question: Where did Warren Harding live the year Coolidge was born? Passage:Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 – January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.
