Example 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 Borbon, known as Carlists. The Carlists were particularly focused on capturing Bilbao, a liberal and economic bastion in northern Spain. The Carlist general Tomas de Zumalacarregui tried to take the city during the Siege of Bilbao of 1835, but he was wounded during a battle near Begona 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.

Example Input: Question: Who moved the farthest to play at Georgetown, Greg Monroe or Henry Sims? Passage:The Hoyas previous season had been a disappointing one in which the relatively young and experienced Georgetown team had fallen from a Top Ten ranking in early January 2009 to a 1615 finish in March that ended with the loss of 12 out of 16 games and first-round exits from both the 2009 Big East Tournament and the 2009 National Invitation Tournament. The Hoyas had lost starting forward DaJuan Summers after the end of the season when he chose to forego his senior year of college and enter the 2009 National Basketball Association draft, as well as starting guard Jessie Sapp, who graduated, and reserve guard/forward Omar Wattad, who transferred. But with freshman forwards Jerrelle Benimon and Hollis Thompson joining the team and sophomore starting center Greg Monroe, junior reserve center Henry Sims, junior starting guards Austin Freeman and Chris Wright, junior reserve forward Julian Vaughn, and sophomore reserve forward Jason Clark all returning, the Hoyas expected to bounce back in 200910. The preseason Associated Press Poll ranked them No. 20.
