Input: Consider Input: Question: How many years passed between the First Carlist War and the  war that mostly in Catalonia? Passage:The Basque Country was one of the main sites of battles during the First Carlist War, a civil war between supporters of the Spanish regent Maria Christina, known as liberals, and those of the late king's brother Carlos of Borbón, known as Carlists. The Carlists were particularly focused on capturing Bilbao, a liberal and economic bastion in northern Spain. The Carlist general Tomás de Zumalacárregui tried to take the city during the Siege of Bilbao of 1835, but he was wounded during a battle near Begoña and died some time after in the town of Zegama. The next year, the city resisted a second siege during which the liberal general Baldomero Espartero defeated the Carlists in the Battle of Luchana. The city was untouched by the Second Carlist War, which took place mostly in Catalonia, but was again an important scenario during the Third Carlist War; in April 1874 the city suffered a third siege which lasted two months.

Input: Consider 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.

Input: Consider Input: Question: Which of the injured players at the beginning of the 2007 season had been with the Green Bay Packers the longest? Passage:The Packers started the game missing two key players of their defense, with injured cornerback Charles Woodson (tied for 7th in the NFL with 4 interceptions) and pass-rushing end Kabeer Gbaja-Biamila (tied for 6th in the NFL with 9.5 sacks) on the inactive list. In the first quarter, Green Bay took the early lead as rookie kicker Mason Crosby completed a 47-yard field goal. On the first play of the Cowboys opening drive, Al Harris stripped the ball from Terrell Owens and side judge Laird Hayes signaled Green Bay ball, but head linesman Derick Bowers overruled him. The only option for Mike McCarthy to challenge on the play, since the whistle was blown, was whether it was a reception – the strip could not be reviewed. The replay upheld the reception and Dallas retained possession. Nick Folk completed a 26-yard field goal to tie the game. Folk also completed a 51-yard field goal, and QB Tony Romo threw a 3-yard TD pass to WR Patrick Crayton. The Packers would end the first quarter with rookie RB Ryan Grant running for a 62-yard touchdown. In the second quarter, Dallas responded with Romo completing a 26-yard TD pass to TE Anthony Fasano and a 10-yard TD pass to WR Terrell Owens. Brett Favre left the game in the second quarter after he hit his right elbow on the helmet of a blitzing Cowboys DB Nate Jones. The throw led to Favre's second interception. Packers quarterback Aaron Rodgers took over for the Packers next series and led the offense on a 74-yard drive, capping it off with an 11-yard TD pass to WR Greg Jennings.
