Example Input: Question: Where is the entity located that the two Phillies pitchers were inducted into? 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 (1912–1917, 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 Boy Wonder's have there been? Passage:Besides the aforementioned death of Stephanie Brown, many other side effects came about from this event. The biggest of these included Black Mask becoming the single crime boss in Gotham, something that would remain until his death at the hands of Catwoman. Another would be Commissioner Akins effectively making all vigilantes criminals, a move that would stay in place for over a year until the return of Commissioner Gordon to the Gotham City Police Department. The more controversial effect, not seen until the follow-up story War Crimes, was turning Doctor Leslie Thompkins against Batman, when she allows Stephanie Brown to die from her wounds as Batman's "punishment" for including children in his war on crime. Jason Todd, a former Boy Wonder, confirmed to be alive on  as a violent vigilante the Red Hood who waged a one-man war against Black Mask and successfully crippling his criminal operation in the city before seeking revenge towards Batman and the Joker. Finally, the citizens of Gotham City no longer consider Batman to be an urban legend (which has been in place since Zero Hour), as he was caught on camera trying to save the life of a wounded student at the end of Act One. Additionally, Barbara Gordon lost the clock tower that served as her home and headquarters and left Gotham City, eventually moving to Metropolis. She would later re-establish her ties to Batman.
