In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage.

[EX Q]: 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.

[EX Q]: Question: How many sales did What's New make? Passage:In 1983 Linda Ronstadt took a break from recording contemporary music in order to make an album of standards with conductor Nelson Riddle, and their collaboration, What's New went triple Platinum. Barbra Streisand's 1985 release The Broadway Album reached number one and went on to quadruple Platinum certification, so a renewed interest in what came to be known as traditional pop was evident. Mathis had not tried a studio album without current hits or new songs since the ill-fated Broadway project in 1965, so his choice to collaborate with Henry Mancini in 1986 for The Hollywood Musicals, which had a lineup of classics that were mostly from the 1940s, was quite a change of pace. And while he has done some albums of contemporary pop songs since then, the category in which he has received four Grammy nominations since 1992 has been Best Traditional Pop Vocal Album, and the industry has recognized his past work as well. Three of his recordings have been inducted into the Grammy Hall of Fame ("Chances Are" in 1998, "Misty" in 2002, and "It's Not for Me to Say" in 2008), and in 2003 he was given the Grammy Lifetime Achievement Award.

[EX Q]: Question: Which of the cities in Austria with tramway systems has the smallest population? Passage:In Austria, Gmunden, Graz, Innsbruck, Linz and Vienna all have tramway systems. With 173.4 km of track, Vienna's network is one of the largest in the world. The cars have been constantly modernised over the years and many are now ultra low-floored. Many of the Austrian tramlines have been in constant operation since they were first opened. Vienna started with horse trams in 1865 and electrification followed in 1897. Graz had horse trams in 1878 and electric cars in 1898 while Linz goes back to 1880 with electrification in 1897. The Gmunden Tramway, only 2.3 km long, is currently one of the shortest in the world, and with gradients of up to 9.6%, it is also one of the steepest and has become a popular tourist attraction. Innsbruck, which traditionally used second-hand trams from other cities, replaced its whole fleet with 32 Bombardier low-floor cars in Summer 2009. The Pöstlingbergbahn, in Linz, an unusual "mountain tramway", has a gradient of 10.6%, which makes it one of the world's steepest gradients on a surviving adhesion-only railway. The tramway now reaches the city centre via the tracks of the urban tram system.
