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: Are the Atlanta Silverbacks still a team? Passage 1:A former England under-21 international, he began his career in Manchester United's youth team before joining Sheffield United in 2001. He soon became a vital player for Neil Warnock's "Blades", and was named on the First Division's PFA Team of the Year in 2002–03, before he helped the Bramall Lane side achieve promotion to the Premier League in 2005–06. After making a total of 302 appearances for the club, he was sold to Stoke City in August 2008 for £2 million. He struggled to break into the first team at Stoke, however, and was sent out on loan to Championship teams Preston North End (twice), Derby County, Barnsley and Leeds United. He joined Leeds on a permanent basis in January 2013. He joined Millwall on loan in January 2015, before he was released from Leeds in May 2015. He signed with Stevenage five months later and was voted the club's Player of the Year for the 2015–16 season. After his 18-month spell ended he joined Port Vale in July 2017.
 Passage 2:He served in the RAF during the war as a navigator on bomber aircraft. He was awarded the DFC for gallantry for saving the crew of his Halifax bomber over Hamburg. During the war he met Terence Rattigan who was then a wireless operator and air gunner. They appeared together in entertainment for fellow servicemen at RAF ground stations. After the war he completed a course at RADA and subsequently joined a company at Barnstaple in Devon. Shortly afterward he formed his own travelling company, the Sage Repertory Group, with £200 given to him by his mother and was joined by three other actors from Barnstaple. An advertisement in The Stage in 1949 offering actors no salary but a share of the profits was answered by John Osborne who joined the company in Ilfracombe. His company took their plays from village to village but enjoyed little success, they presented a summer residency at the Victoria Theatre on Hayling Island but this too was short-lived. Shortly after he collaborated on two plays with Osborne, the first Personal Enemy fell foul of the censors at the time, the second was An Epitaph for George Dillon.
