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.
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.

Explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this: Question: Is Disko Island the main island in Greenland? Passage 1:Golay was born in Windsor, Missouri, on July 2, 1915, and served in the United States Navy during World War II. After his military service, Golay obtained a doctorate in economics from the University of Chicago in 1951, and worked for the Federal Reserve Board until 1953, when he joined the Cornell University as an assistant professor of economics and Asian studies. In 1960, Golay received a Guggenheim fellowship. He was named chair of the Cornell Department of Economics in 1963, and left the position in 1967. He taught at SOAS, University of London as a visiting professor on a Fulbright grant from 1965 to 1966. Between 1970 and 1976, Golay led the Cornell Southeast Asia Program. Golay was a visiting professor at the University of the Philippines from 1973 to 1974 as a recipient of a Rockefeller Foundation grant. He retired from Cornell in 1981, and served as president of the Association for Asian Studies in 1985. Golay died on August 31, 1990, at the veterans' hospital in Oxford, New York.
 Passage 2:Brazil faced Chile in the round of 16, taking an 18th-minute lead through David Luiz's first goal for the Seleção. With no further scoring after Alexis Sánchez's equaliser, the match went to a penalty shootout. Brazil prevailed 3–2, with Neymar, David Luiz and Marcelo converting their kicks, and goalkeeper Júlio César saving from Chileans Sánchez and Mauricio Pinilla. The team again faced South American opposition in the quarter-final, defeating Colombia 2–1 with goals from central defenders David Luiz and team captain Thiago Silva. Late in the match, Neymar was substituted on a stretcher after Camilo Zúñiga's knee had made contact with the forward's back. Neymar was taken to hospital and later diagnosed with a fractured vertebra, which ruled him out for the remainder of the tournament. Prior to this, Neymar had scored four goals, provided one assist and been named man of the match twice. Brazil faced further problems ahead of their semi-final against Germany, as Thiago Silva was to serve a one-match suspension for receiving his second yellow card of the tournament in the quarter-final. The Seleção went on to lose 1–7 to the Germans, their biggest ever defeat at the World Cup and first home loss in a competitive match since 1975. Towards the end of the match, the home crowd began to "olé" each pass from the German team, and booed their own players off the pitch after the final whistle. The match has been nicknamed the Mineirazo, making reference to the nation's previous World Cup defeat on home soil, the Maracanazo against Uruguay in 1950, and the Estádio do Mineirão in Belo Horizonte where the match took place.
 Passage 3:Lerdorf was born on Disko Island in Greenland and moved to Denmark in his early years. Lerdorf's family moved to Canada from Denmark in 1980, and later moved to King City, Ontario in 1983. He graduated from King City Secondary School in 1988, and in 1993 he graduated from the University of Waterloo with a Bachelor of Applied Science in Systems Design Engineering. He contributed to the Apache HTTP Server and he added the LIMIT clause to the mSQL DBMS. A variant of this LIMIT clause had already been around for a decade in mainframe relational database management systems (like Oracle Rdb running on VAX/VMS, formerly from Digital Equipment Corporation), but apparently it had not yet been picked up by the emerging PC-based databases. It was later adapted by several other SQL-compatible DBMS. He released the first version of PHP in 1995.
