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 army did the USS Gunston Hall engage with during the assault on Kwajalein?  Passage 1:Phang started his reggae label Powerhouse in the early 1980s. His first hits were Little John's "True Confessions" and "Roots Girl", both released in 1983. He followed suit with Sugar Minott's "Buy off the Bar" and Barrington Levy's "Money Move" which were both two major hits that year. In the summer of 1984 he released Michael Palmer's "Lick Shot" which became of the biggest tunes that summer. Many of the most successful dancehall stars of the 1980s recorded for Phang. Half Pint's all-time greatest hit "Greetings" was released on Powerhouse in 1986. Conroy Smith's first song "Indian Lady" was also released on Phang's label. Other artists include Josey Wales, Freddie McGregor, Nitty Gritty, Tenor Saw, Little John, Brigadier Jerry, Barrington Levy, Admiral Bailey, Al Campbell, Charlie Chaplin, Cutty Ranks, Dominic, Echo Minott, Frankie Paul, Gregory Isaacs, John Wayne, Yellowman, Supercat, and General Echo. Phang mostly used riddims produced by Sly & Robbie, this gave him an advantage compared to other producers. His sound is characterized by the abundant use of reverb on the snare drums. However, by the late 1980s he stopped producing music. Phang was a key influence on Philip "Fatis" Burrell's move into record production.
 Passage 2:Corona's first single, "The Rhythm of the Night", was released in Italy in November 1993 on Roberto Zanetti’s DWA record label, and became an instant hit. It featured the voice of Italian singer Giovanna Bersola, better known by her stage name Jenny B. It stayed at number 1 on the Italian music chart for eight consecutive weeks. However, the song was not released elsewhere until the following year. A remixed version of the song became a number 2 hit in the United Kingdom in September 1994. Like several early 1990s Eurodance/Hi-NRG songs that eventually became American hits, such as "Get Ready For This", "Twilight Zone" and "Tribal Dance" by 2 Unlimited and "Strike It Up", "I Don't Know Anybody Else" and "Everybody Everybody" by Black Box, "The Rhythm of The Night" did not become popular in the United States until well after its success had peaked in Europe. However, by spring 1995, the song was all over American radio and clubs, eventually reaching #11 on the Billboard Hot 100. The song was later released as a track in the 1995 debut studio album "The Rhythm of the Night". Lead vocals for the remaining songs in the album were provided by Welsh singer Sandy Chambers who would also provide vocals on the group's second album Walking On Music.
 Passage 3:After intensive shakedown along the California coast Gunston Hall prepared to sail for the Western Pacific, where she was to participate in every major operation from February 1944 to the end of the war, 18 months later. Loading 225 men from the 4th Marine Tank Battalion and 2 amphibious units, as well as 15 LVTs, 15 tanks, 17 LCMs, and 15,000 gallons of gasoline, Gunston Hall departed San Diego on 13 January 1944. On D-Day for the assault on Kwajalein, 1 February 1944, she stood offshore to unload her cargo as the Marines stormed the beaches on Roi and Namur Islands. Gunston Hall remained in the area to repair small craft until 6 February, when she reembarked her former passengers and equipment and sailed to Guadalcanal via Funa Futi. The pattern she set here held for her participation in eight further key invasion efforts in the Pacific as the Navy "Island-hopped" marines and Army troops ever closer to the Japanese home islands.
