In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

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 year did the regiment's title change? Passage 1:Davis won Emmys in 1990 for Beauty and the Beast and 1995 for SeaQuest DSV. He wrote scores mostly for television series up until 1995, in which he wrote a few of the cues for the animated Disney motion picture A Goofy Movie. He continued to score television series until the two then young directors, the Wachowskis, hired him to score their neo-noir film Bound. It was reasonably successful at the box office. Bound was the film which led Davis into becoming the composer for the entire Matrix trilogy. Subsequently, Davis has composed scores for films such as Jurassic Park III (recommended to the filmmakers by John Williams, the composer of the scores for the first two films in the series), House on Haunted Hill, Behind Enemy Lines, and The Unsaid. In 2004, he produced the music score for the BBC science fiction documentary series Space Odyssey: Voyage to the Planets, released as Voyage to the Planets and Beyond in the United States.
 Passage 2:The King's Royal Rifle Corps was an infantry rifle regiment of the British Army that was originally raised in British North America as the Royal American Regiment during the phase of the Seven Years' War in North America known as 'The French and Indian War.' Subsequently numbered the 60th Regiment of Foot, the regiment served for more than 200 years throughout the British Empire. In 1958, the regiment joined the Oxfordshire and Buckinghamshire Light Infantry and the Rifle Brigade in the Green Jackets Brigade and in 1966 the three regiments were formally amalgamated to become the Royal Green Jackets. The KRRC became the 2nd Battalion, Royal Green Jackets. On the disbandment of the 1st Battalion, Royal Green Jackets in 1992, the RGJ's KRRC battalion was redesignated as the 1st Battalion, Royal Green Jackets, eventually becoming 2nd Battalion, The Rifles in 2007.
 Passage 3:Roger Ebert of the Chicago Sun-Times gave the film three stars out of four and wrote that "the musical scenes are the best rock coverage since 'Woodstock.' The sound is first rate, for one thing, and director Pierre Adidge has some idea of why Cocker electrifies a crowd." Vincent Canby of The New York Times called the film a "most satisfying, record-album of a movie" which "patronizes neither its audience nor its stars ... It is uncluttered, one of the best concert films so far." A review in Variety said, "Considerable technical expertise has gone into this production, and though the objective may be clear, it just hasn't turned out to be another 'Woodstock,' possibly because Joe Cocker's personality isn't all that endearing." Gene Siskel of the Chicago Tribune rated the film three stars out of four and wrote, "'Mad Dogs' is distinguishable from other 'rockumentaries' because it deals almost exclusively with the musician and his music. There are few side trips to cultural comments." Robert Hilburn of the Los Angeles Times stated, "As a film, 'Mad Dogs and Englishmen' is a good concert. For much of the picture's 114 minutes, the camera is on Joe Cocker, by most standards the best and most exciting singer in rock music ... But 'Mad Dogs and Englishmen,' unfortunately, fails in the end to rise above this interesting, but clearly limited historical summary of the Cocker tour. As a film, it doesn't establish its own importance." A negative review by Tom Zito of The Washington Post advised readers to "Forget the film and try the record," explaining, "What emerges from all this is roughly two hours of footage that looks terrible on the screen and sounds almost as bad. The film is projected in an annoying square format, except for the moments when the screen area is broken up into some poorly coordinated split-screen effects. The camerawork is often sloppy ... the whole thing winds up looking and sounding like a cheap, imitation (indoor) 'Woodstock.'" James D. White of The Monthly Film Bulletin declared that "The music itself is excellent," but "The film's information content is minimal; and one's heart sinks as the screen is split into a double image for the first number and as the mandatory shots—of excited fans, of joint-rolling in a hotel bedroom, of an interview with a vacuous groupie—are inevitably wheeled out."
