Question: Question: How many people live in the city where Kirdorf was born? Passage:Emil Kirdorf was born at Mettmann, Rhine Province. His father was a wealthy owner of a weaving mill. He had a brother named Adolf who would be his business partner during his adult life. Kirdorf volunteered a year in 1864 in Hamburg to work in an export enterprise. A year later, he worked in a textile company in Krefeld. The family's mill went bankrupt, mainly because of the management's refusal to introduce mechanical looms. Kirdorf therefore changed to mining industry in which he worked as an accountant. Following the Franco-Prussian War, he became director of Zeche Holland in 1871. Two years later, the entrepreneur Friedrich Grillo offered him the position of commercial director in the Gelsenkirchener Bergwerks-AG (GBAG) company. He became general manager of GBAG in 1893. He steered the company through the Long Depression of the 1870s, and held this position until 1926.

Question: Question: What countries was John Hope's Brigade stationed in? Passage:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.

Question: Question: What was the best season South Fremantle had while Nicky Winmar was part of the club? Passage:Growing up in Pingelly in the Wheatbelt region of Western Australia, Winmar began his career with South Fremantle, playing 58 games at the club before being recruited prior to the 1987 season by St Kilda. In a twelve-season career with St Kilda, Winmar won the club's best and fairest award, the Trevor Barker Award, in 1989 and 1995 and was also twice named in the All-Australian team. He left St Kilda at the end of the 1998 season and was drafted by the Western Bulldogs, playing one further season in the AFL before retiring at the end of the 1999 season. Having represented Western Australia in eight interstate matches, Winmar was named in St Kilda's in 2003 and was inducted into the West Australian Football Hall of Fame in 2009. An Indigenous Australian, he was the first Aboriginal footballer to play 200 games in the AFL and was named in the Indigenous Team of the Century in 2005.
