Example input: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Q: Question: During which centuries were the Kyoto Imperial Palace and the Sento Imperial Palace home to the Emperors of Japan? Passage 1:Denver had long been a hotbed of Denver Bears/Zephyrs minor league baseball and many in the area desired a Major League team. Following the Pittsburgh drug trials, an unsuccessful attempt was made to purchase the Pittsburgh Pirates and relocate them. However, in 1991, as part of Major League Baseball's two-team expansion (along with the Florida (now Miami) Marlins), an ownership group representing Denver led by John Antonucci and Michael I. Monus was granted a franchise; they took the name "Rockies" due to Denver's proximity to the Rocky Mountains, which is reflected in their logo; the name was previously used by the city's first NHL team (who are now the New Jersey Devils). Monus and Antonucci were forced to drop out in 1992 after Monus' reputation was ruined by an accounting scandal. Trucking magnate Jerry McMorris stepped in at the 11th hour to save the franchise, allowing the team to begin play in 1993. The Rockies shared Mile High Stadium (which had originally been built for the Bears) with the National Football League (NFL)'s Denver Broncos for their first two seasons while Coors Field was constructed. It was completed for the 1995 Major League Baseball season.
 Passage 2:Norman Surplus (born 1963) is a Northern Irish pilot, who became the first person to circumnavigate the globe in an autogyro, nicknamed "Roxy". His trip began in 2010 and ended on 28 June 2019. In 2010, during the first leg of his trip, Surplus flew over Europe, the Middle East, Asia, and North America. In June 2015, Surplus commenced the second leg of his journey by flying through the United States and crossing the Atlantic Ocean to eventually land in Larne, Northern Ireland in August 2015, becoming the first person to cross the Atlantic in an autogyro. In 2019, he completed the last leg of his journey when he finally obtained permission from the Russian Federation to fly through its airspace. He left Ireland on Easter Monday in 2019, and flew through Russia to eventually reach the United States and land at the Evergreen Aviation and Space Museum in Oregon completing his circumnavigation of the globe in an autogyro. Surplus's AutoGyro MT-03 is currently displayed at the EAA Aviation Museum and will remain there for the duration of AirVenture 2020. Surplus took nine years to complete his journey around the world, and flew over 32 countries, over a total distance of . In a 2015 interview with the CBC, while on a stopover at Iqaluit, Canada, Surplus mentioned that the trip should have taken approximately four months but the problems with obtaining permission to fly over Russia, which persisted for three years, derailed his plans.
 Passage 3:With its 2,000 religious places – 1,600 Buddhist temples and 400 Shinto shrines, as well as palaces, gardens and architecture intact – it is one of the best preserved cities in Japan. Among the most famous temples in Japan are Kiyomizu-dera, a magnificent wooden temple supported by pillars off the slope of a mountain; Kinkaku-ji, the Temple of the Golden Pavilion; Ginkaku-ji, the Temple of the Silver Pavilion; and Ryōan-ji, famous for its rock garden. The Heian Jingū is a Shinto shrine, built in 1895, celebrating the Imperial family and commemorating the first and last emperors to reside in Kyoto. Three special sites have connections to the imperial family: the Kyoto Gyoen area including the Kyoto Imperial Palace and Sentō Imperial Palace, homes of the Emperors of Japan for many centuries; Katsura Imperial Villa, one of the nation's finest architectural treasures; and Shugaku-in Imperial Villa, one of its best Japanese gardens. In addition, the temple of Sennyu-ji houses the tombs of the emperors from Shijō to Kōmei.
