Input: Consider Input: Question: How long before Fort Mercer built was the city it was built to protect established? Passage:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.


Output: Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side


Input: Consider Input: Question: How old was the manager of the Movistar team when the 2015 Vuelta a Espana began? Passage:The first five stages took place in and around Andalusia in southern Spain; the 2014 Vuelta had also started there. The first stage was a team time trial along the coast from Puerto Banús to Marbella. The next four stages were fairly flat, although Stage 2 finished on a moderately difficult climb. The sixth stage started in Córdoba and finished in Sierra de Cazorla in Jaén on another moderately difficult climb. The seventh stage then returned to Andalusia for the first major difficulty of the race: the first-category summit finish at La Alpujarra. The route then continued along the eastern coast of Spain, with a medium-mountain seventh stage and another first-category summit finish at Benitachell on Stage 9. There was one more medium-mountain stage on Stage 10, taking the riders into the Province of Castellón. This was followed by a transfer that took the riders into Andorra for a three-day spell, beginning with the first rest day. The eleventh stage took place entirely in Andorra; though it was only in length, it included six categorised climbs, including a summit finish, and was described by Eusebio Unzué (the manager of the Movistar team) as "the toughest Vuelta stage that he has seen in more than 30 years". Stage 12 took the riders back into Spain for a fairly flat stage, before three consecutive stages with summit finishes. These took place in the mountains of Cantabria and Asturias and were followed by the race's second rest day. The final week of the race included no summit finishes: the first stage was a individual time trial in Burgos and was then followed by three mixed stages that took the riders nearer to the final stage of the race, a sprint stage in Madrid. For the first time, the race organisers also held a women's race on the same day as the final stage, using the same circuit. This race – called La Madrid Challenge by La Vuelta – was won by Shelley Olds.


Output: The eleventh stage took place entirely in Andorra; though it was only in length, it included six categorised climbs, including a summit finish, and was described by Eusebio Unzué (the manager of the Movistar team) as "the toughest Vuelta stage that he has seen in more than 30 years"


Input: Consider Input: Question: What species or race is the Steward of the Throne? Passage:Meanwhile, the wizard Gandalf the White and the hobbit Pippin arrive at Minas Tirith to warn Denethor, the Steward of the Throne, about the upcoming war—only to discover that the Steward has become insane and means to take his own life. Frodo and Samwise continue toward Mount Doom (eluding Ringwraiths and infiltrating a "battalion of orcs" in the process) only to be attacked by Gollum. As Sam holds Gollum off, Frodo reaches the Crack of Doom; but is subverted by the Ring. At the same time, Gondor's neighboring country, Rohan, helps it claim victory in the Battle of Pelennor Fields, where King Théoden and the Witch-King of Angmar are slain. Upon his own arrival, Aragorn plans to confront Sauron at the gates of Mordor. Here, he quarrels with the Mouth of Sauron and the two armies prepare for battle.
