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: What was the population in Bleu's hometown when he started his career? Passage 1:The main event of the night featured WWF World Heavyweight Champion Shawn Michaels defending the title against the British Bulldog. Just before the match began, as scripted, Michaels was served a summons from Bulldog's storyline attorney Clarence Mason. It stated that Michaels was a defendant with the charge of "attempted alienation of affection" due to the allegation of him making advances towards Bulldog's wife (storyline and real life) Diana Smith, therefore causing strain in their marriage. The timing of the subpoena by Bulldog's camp was an attempt to throw Michaels off his game, giving Bulldog a better chance of winning the championship. During the match, as part of the script, Bulldog accidentally ran into referee Earl Hebner, knocking him out for a period of time. A replacement referee (Mike Chioda) continued the match. Shawn Michaels performed a German suplex into a pinfall combination on Bulldog. By this time, the original referee had regained his senses, and both referees counted the pinfall. Both wrestlers had their shoulders on the mat as Chioda counted Michaels' shoulders down, while Hebner counted Bulldog's down. Due to both wrestlers being pinned simultaneously, the match was ruled a draw and Michaels retained the WWF Championship. 
 Passage 2:Don Bleu (real name Rick Kelleher) is an American retired radio personality and former television host. He grew up in East Grand Forks, Minnesota and began his career in 1966, when his friend Shadoe Stevens encouraged him to try radio.

His success at KDWB earned him a job at KHJ (AM) in Los Angeles. In 1980, he moved to San Francisco and worked in the adult contemporary radio genre. Most recently, he hosted the Don Bleu Show on KOSF, a music station in San Francisco, California. He was named to the Pavek Museum of Broadcasting's Minnesota Broadcasting Hall of Fame in 2005, and in 2007 he was inducted into the Bay Area Radio Hall of Fame.
