Example Input: Question: Did the Phillies win the league championship the year that Roberts won 20 games? Passage:Of those Phillies, 97 have had surnames beginning with the letter R. Two of those players have been inducted into the Baseball Hall of Fame: pitcher Eppa Rixey, who was a Phillie for six seasons in two different stints (19121917, 1919); and Robin Roberts, who won 20 games during the 1950 season as the ace pitcher of the Whiz Kids. The Hall of Fame lists the Phillies as Roberts' primary team; during his career, the right-hander won 234 games and lost 199, the latter one of his three franchise records. During his 14 seasons with the team, he pitched 3,739 innings and completed 272 games, both records; he also held the major league record for most career home runs allowed until it was broken in 2010. Roberts was also elected to the Philadelphia Baseball Wall of Fame as the Phillies' first inductee in 1978.

Example Input: Question: How many races had Sellers run the year he replaced Josh Reaume? Passage:Obaika Racing entered competition in 2015. The team signed driver Josh Reaume, who met team owner Victor Obaika while on humanitarian missions in Africa as a child. The 97 team debuted at the Daytona International Speedway in the Xfinity Series season-opening Alert Today Florida 300, with Reaume finishing 23rd. After three races, with one DNQ, Peyton Sellers replaced Reaume. In April 2015, the team secured their first sponsor vacation provider VroomBrands, which is owned by Obaika. VroomBrands wrapped the No. 97 in designs such as a Zebra representing their African safari package (debuted at Richmond International Raceway) and the Cheetah print representing their tours in Asia (debuted at Talladega Superspeedway). At the Winn-Dixie 300 at Talladega, Sellers scored the team's first top-20 finish, finishing 18th despite being involved in a ten-car wreck that sent cars spinning down pit road. Johanna Long replaced Sellers for the U.S. Cellular 250 at Iowa Speedway. After one more start for Sellers at Watkins Glen, the team introduced various drivers for the rest of the season. Dylan Kwasniewski debuted with the team in the Nationwide Children's Hospital at Mid-Ohio Sports Car Course, finishing 34th due to mechanical problems after running in the top 10. Kwasniewski would run the next two races for the team. Parker Kligerman drove the car in the VFW Sport Clips Help a Hero 200 at Darlington Raceway, Mason Mingus in the Furious 7 300 at Chicagoland Speedway, and Ryan Ellis in the Hisense 200 at the Dover International Speedway.

Example Input: Question: In which city did Jowett attend school when he was twelve? Passage:Jowett was born in Peckham, Kent, and grew up in Camberwell, the third of nine children. His father was a furrier originally from a Yorkshire family that, for three generations, had been supporters of the Evangelical movement in the Church of England, and an author of a metrical translation of the Old Testament Psalms. His mother was a Langhorne, related to John Langhorne, the poet and translator of Plutarch. At twelve, Jowett was placed on the foundation of St Paul's School (then in St Paul's Churchyard) where he soon gained a reputation as a precocious classical scholar. Aged eighteen he was awarded an open scholarship to Balliol College, Oxford, where he remained for the rest of his life. He went up in 1836, and was quickly recognized as one of the leading Oxford dons of his generation, made a Fellow while still an undergraduate in 1838; he graduated with first-class honours in 1839. This was at the height of the Oxford Tractarian movement: through the friendship of W. G. Ward he was drawn for a time in the direction of High Anglicanism; but a stronger and more lasting influence was that of the Arnold school, represented by A. P. Stanley. The controversy caused Jowett to withdraw from High Table at college to lodgings in Broad Street.
