Example Input: Question: Is the fort built to protect Philadelphia on the Pennsylvania side still standing? 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.

Example Input: Question: When did the person who von Blumenthal served under in the First Schleswig War first achieve their rank? Passage:Brought up on his grandfather's estate at Reddentin, where his uncle Gustav von Below was founding what would become the Pentecostal movement, von Blumenthal was educated at the military schools of Culm and Berlin. He entered the Guards as 2nd lieutenant in 1827. He studied at the Berlin General War School (later called the Prussian Military Academy). After serving in the Rhine Province, he joined the topographical division of the general staff in 1846. As lieutenant of the 31st foot, he took part in 1848 in the suppression of the Berlin riots, and in 1849 was promoted captain on the general staff.
