Example Input: Question: What year did the Steelers appear in their first Super Bowl? Passage:The Pittsburgh Steelers compete in the National Football League (NFL) as a member club of the American Football Conference (AFC) North division. Founded in 1933, the Steelers are the oldest franchise in the AFC; seven franchises in the National Football Conference (NFC) have longer tenures in the NFL. The team struggled to be competitive in its early history, posting winning records in just 8 of its first 39 seasons. Since the AFL–NFL merger in 1970, however, it has appeared in eight Super Bowls and one of only two teams, along with the New England Patriots have won the Super Bowl six times. The six championships place the Steelers fourth in the league in terms of total championships (including those prior to the first Super Bowl), trailing only the Green Bay Packers (13 championships), the Chicago Bears (9) and the New York Giants (8). The club's 15 AFC Championship Game appearances are second all-time, behind the Patriots (16). In addition, they have hosted the second-most conference championship games (11) than any franchise in either conference, and are tied for second with the Dallas Cowboys and Denver Broncos with eight Super Bowl appearances; the Patriots currently hold the record of eleven appearances, as of 2019.

Example Output: Since the AFL–NFL merger in 1970, however, it has appeared in eight Super Bowls and one of only two teams, along with the New England Patriots have won the Super Bowl six times

Example Input: Question: How many battles had Oswald Watt commanded by the year Holden joined the Australian Imperial Force? Passage:Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No. 2 Squadron. Commanded by Major Oswald Watt, No. 2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.

Example Output: Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private

Example Input: Question: What part of England was the area that produced fustian located in? Passage:In the 18th century, England was famous for its woollen and worsted cloth. That industry, centred in the east and south in towns such as Norwich, jealously protected their product. Cotton processing was tiny: in 1701 only of cottonwool was imported into England, and by 1730 this had fallen to . This was due to commercial legislation to protect the woollen industry. Cheap calico prints, imported by the East India Company from Hindustān (India), had become popular. In 1700 an Act of Parliament passed to prevent the importation of dyed or printed calicoes from India, China or Persia. This caused demand to switch to imported grey cloth instead—calico that had not been finished—dyed or printed. These were printed with popular patterns in southern England. Also, Lancashire businessmen produced grey cloth with linen warp and cotton weft, known as fustian, which they sent to London for finishing. Cottonwool imports recovered though, and by 1720 were almost back to their 1701 levels. Again the woollen manufacturers, in true protectionist fashion, claimed that the imports were taking jobs away from workers in Coventry. The Woollen, etc., Manufactures Act 1720 was passed, enacting fines against anyone caught wearing printed or stained calico muslins. Neckcloths and fustians were exempted. The Lancashire manufacturers exploited this exemption; coloured cotton weft with linen warp were specifically permitted by the 1736 Manchester Act. There now was an artificial demand for woven cloth.

Example Output:
