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.

Let me give you an 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.

Question: Which took longer to complete, the construction of the air base, or that of the other large earth-moving project it was equivalent to? Passage 1:Zabica started his career with Cockburn City before joining Adelaide City for seven seasons, winning National Soccer League championships in 1992 and 1994. He played for Australia in the qualifiers for the 1994 FIFA World Cup finals, losing narrowly to Argentina. A nagging knee injury forced his international retirement, but he made a comeback in 1995 with Dalmatinac with whom he won the D'Orsogna Cup. He made his State debut at the age of 31, captaining the side that beat West Ham United in 1995, and went on to play a further five times for Western Australia. He returned to national league level in 1997, making seven appearances for Perth Glory and taking his career tally to 202 games. He had a three-match spell in England with Bradford City in late 1997 and returned to Perth to play for Bayswater City SC, Inglewood United and Fremantle City.
 Passage 2:In 1947, Allen Noonan was a pictorial sign painter in Long Beach, California, who that year claimed to have an encounter with Galactic Space Beings. While painting a signboard he said he was beamed up into a Mothership. He then changed his name to Allen Michael. He claimed to have physically encountered a flying saucer in 1954 at Giant Rock in the Mojave Desert of California. During the Summer of Love, he began the One World Family Commune with a vegan restaurant on the northeast corner of Haight and Scott streets in San Francisco, California, called the Here and Now. 7 similar restaurants followed. His communal group lived in two large houses during the early 1970s in Berkeley, California. In 1969, the commune established a vegan restaurant in a much larger space on Telegraph Avenue and Haste Street in Berkeley and the name of the restaurant was changed to the One World Family Natural Food Center. They published a vegetarian cookbook called Cosmic Cookery. There was a large mural on the side of the restaurant painted by Allen Michael that had written above it the phrase Farmers, Workers, Soldiers Unite — The People's Spiritual Reformation 1776–1976! The farmer was holding a pitchfork, the worker was holding a hammer, and the soldier was holding a gun, and they had their arms around each other's shoulders. Above the three were three flying saucers coming in for a landing. In 1973, Allen Michael founded "The Universal Industrial Church of the New World Comforter" and published the first volume of his channeled revelations, The Everlasting Gospel. In 1975, the church headquarters and the vegetarian restaurant relocated to Stockton, California. Allen Noonan ran for president of the United States in the 1980 and 1984 elections on the Utopian Synthesis Party ticket.
 Passage 3:In 1950, Admiral Arthur W. Radford, Commander-in-Chief of the United States Pacific Fleet, envisioned an naval base in the Western Pacific to enhance Seventh Fleet capabilities. The Korean War began and the Navy realized it had a need for an air station in the region. Cubi Point in the Philippines was selected, and civilian contractors were initially approached for the project. After seeing the Zambales Mountains and the surrounding jungle, they claimed it could not be done. The U.S. Navy then turned to the Seabees and was told no problem, Can do. The first Seabees to arrive were surveyors of Construction Battalion Detachment 1802. Moblie Comstruction Battalion 3 arrived on 2 October 1951 to get the project going and was joined by MCB 5 in November. Over the next five years, MCBs 2, 7, 9, 11 and CBD 1803 also contributed to the effort. They leveled a mountain to make way for a nearly runway. NAS Cubi Point turned out to be one of the largest earth-moving projects in the world, equivalent to the construction of the Panama Canal. Seabees there moved of dry fill plus another 15 million that was hydraulic fill. The $100 million facility was commissioned on 25 July 1956, and comprised an air station with an adjacent pier capable of docking the Navy's largest carriers. Adjusted-for-inflation, today's price-tag for what the Seabees built at Cubi Point would be $906,871,323.53. After decades of use by American forces, Mount Pinatubo erupted in 1991, burying Cubi Point in 18-36 inches of ash. Despite this, the American government wished to keep the Subic Naval Base and signed a treaty with the Philippine government. The treaty was not ratified, however, failing by a slim margin in the Philippine Senate. Attempts to negotiate a new treaty were soon abandoned and the United States was informed that it was to withdraw within one year. U.S. forces withdrew in November 1992, turning over the facility with its airport to the Philippine government.
