One 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.

Now, solve this: Question: How old was Takanosato when he reached yokozuna ranking? Passage 1:A former amateur champion at Nihon University, he turned professional at the age of 23, joining Kasugano stable in March 1981. He reached the top makuuchi division in September 1983, and in 1984 he earned his first special prize for Fighting Spirit, and defeated Takanosato in his first ever bout against a yokozuna to earn his first of his three kinboshi. He spent most of 1985 in the second jūryō division, but in 1986 made the san'yaku ranks at komusubi. In November 1987 he scored 10–5 from the maegashira 6 ranking, defeating two ōzeki and winning the Technique Prize. This earned him promotion to his highest rank of sekiwake for the following tournament in January 1988. However, by the end of the year he was in jūryō again due to injury problems. He won the jūryō yūshō on two occasions in 1989 and won promotion back to the top division. After missing the September 1990 tournament he fell to jūryō again and made only one more appearance in makuuchi before retiring in May 1992 at the age of 34.
 Passage 2:Tanaka subsequently teamed with Mitsu Arakawa in the WWF, acquiring the International Tagteam Championship; losing it at Madison Square Garden to Tony Marino and Victor Rivera. The team of Tanaka and Fuji won three WWWF World Tag Team Championships, with Blassie as manager for the third reign and The Grand Wizard as manager for the first two. They first won the belts from Sonny King and Chief Jay Strongbow on June 27, 1972 in Philadelphia, PA at a House show.

Their third win came on September 27, 1977 at a Philadelphia house show when they defeated Tony Garea and Larry Zbyszko in a tournament final for the vacant belts, holding them until March 14, 1978 when they lost the titles to Dino Bravo and Dominic DeNucci in Philadelphia. This third reign set a record for number of championship reigns which would be equalized by The Wild Samoans in 1983, Demolition in 1990, Money Inc. in 1993, The Quebecers in 1994 and The Smoking Gunns in 1996, but not bettered until The New Age Outlaws won a fourth reign in 1999.
