Example Input: 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.

Example Input: Question: What team did Nick Foles play for when Minshew made his debut? Passage:On September 8, 2019, Minshew made his NFL debut against the Kansas City Chiefs when starter Nick Foles was taken out of the game due to a shoulder injury. He completed 22 of 25 passes for 275 yards, two touchdowns and an interception in the 40–26 loss. Minshew's pass completion percentage of 88% is the highest of any player making his debut in NFL history (minimum 15 pass attempts, since at least 1950), and also the highest single-game pass completion percentage in Jaguars history. Minshew was named the starter going forward after it was revealed that Foles had suffered a broken clavicle. During Week 2 against the Houston Texans, Minshew finished with 213 passing yards and a touchdown along with 56 rushing yards as the Jaguars lost 13–12. In Week 3, against the Tennessee Titans on Thursday Night Football, he earned his first victory as a professional. He passed for 204 yards and two touchdowns in the 20–7 victory. In Week 4, against the Denver Broncos, he passed for 213 yards and two touchdowns in the 26–24 victory. Late in the game, he engineered a drive that helped set up the Jaguars' game-winning field goal by Josh Lambo. During Week 5 against the Carolina Panthers, Minshew finished with 374 passing yards and two touchdowns as the Jaguars lost 27–34. After a Week 6 loss to the New Orleans Saints and a Week 7 victory over the Cincinnati Bengals, he had 279 passing yards and three passing touchdowns in a 29–15 victory over the New York Jets. During Week 9 against the Texans at Wembley Stadium, Minshew finished with 309 passing yards and 2 interceptions as the Jaguars lost 3–26. Days later, it was announced that Minshew would resume the backup role after Foles returned from his collar bone injury.

Example Input: Question: Where was the author of the book that Ken Baxter was fascinated with born? Passage:Baxter publicly credits his fascination with the space program to reading From the Earth to the Moon by Jules Verne as a young boy. Baxter holds the distinction of First Founder of Virgin Galactic, a space tourism company announced by Sir Richard Branson on September 25, 2004. Baxter purchased the first commercial space flight ticket at $200,000 USD after viewing a 60 Minutes segment featuring Burt Rutan, winner of the $10,000,000 X Prize for the first non-governmental organization to launch a reusable manned spacecraft into space twice within two weeks, and thereafter, earning him the nickname "Rocket Man". Rutan is also the designer of Sir Richard Branson's SpaceShipTwo, which attached to the mother ship, will be carried to about 16 kilometers or 52,000 feet by a carrier aircraft, White Knight Two. At that point, when the carrier aircraft reaches its maximum height, the SpaceShipTwo vehicle will separate and continue to over 100 km (the Kármán line, a common definition of where "space" begins). Despite the crash of the first iteration of SpaceShipTwo during a test flight on October 31, 2014, Baxter remains optimistic about his upcoming flight and continues to hold his place at the top of the passenger list to become the world's first commercial space tourist.
