Example: 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.

 Passage 2:In 2010 Richards was invited to take part in New Japan Pro Wrestling's Best of the Super Juniors tournament along with fellow North American and ROH wrestler, Kenny Omega. Richards entered the two-week-long tournament on May 30, but although he managed to win five out of his seven matches, he finished third in his block and narrowly missed advancing to the semifinals of the tournament. After the tournament Richards began working regularly for New Japan Pro Wrestling, joining the promotion's top heel stable Chaos, and no longer made appearances for Pro Wrestling Noah. In November 2010 Richards and Rocky Romero, reviving the No Remorse Corps name, made it to the finals of a five-day-long Super J Tag League tournament, before being defeated by their Chaos team mates Jado and Gedo. On December 11, 2010, Richards received a shot at the IWGP Junior Heavyweight Championship, but was defeated by the defending champion, Prince Devitt. On May 3, 2011, Richards and Romero unsuccessfully challenged Devitt and Ryusuke Taguchi, known collectively as Apollo 55, for the IWGP Junior Heavyweight Tag Team Championship. On May 26, Richards entered the 2011 Best of the Super Juniors tournament and after winning six out of his eight round robin stage matches, which included a win over the reigning IWGP Junior Heavyweight Champion Prince Devitt, Richards finished second in his block and advanced to the semifinals of the tournament. On June 10, Richards was eliminated from the tournament in the semifinals by the eventual winner of the entire tournament, Kota Ibushi. On October 10, 2011, at Destruction '11, Richards and Romero defeated Prince Devitt and Ryusuke Taguchi to win the IWGP Junior Heavyweight Tag Team Championship for the first time. Richards and Romero made their first successful title defense on November 12 at Power Struggle, defeating the team of Kushida and Tiger Mask. As a result of pinning Prince Devitt in the IWGP Junior Heavyweight Tag Team Championship match, Richards was granted another shot at his IWGP Junior Heavyweight Championship on December 4, but failed in his attempt to become a double champion. On January 4, 2012, at Wrestle Kingdom VI in Tokyo Dome, Richards and Romero lost the IWGP Junior Heavyweight Tag Team Championship back to Devitt and Taguchi. On February 12 at The New Beginning, the No Remorse Corps defeated Apollo 55 to regain the IWGP Junior Heavyweight Tag Team Championship. As a result, Richards received his third shot at the IWGP Junior Heavyweight Championship on March 10, but was yet again defeated by Prince Devitt. On May 2, Richards and Romero were stripped of the IWGP Junior Heavyweight Tag Team Championship, after a car accident forced Richards to miss his flight to Japan and the following day's Wrestling Dontaku 2012 event, where the two were scheduled to defend the title against Jushin Thunder Liger and Tiger Mask. Despite being able to wrestle in the United States, New Japan also pulled Richards from the 2012 Best of the Super Juniors tournament, citing doctor's orders.
