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: Was Viborg Ff still operational when Burns earned a place in his first All-Star game? Passage 1:Finucane was born into a prominent republican family on the Falls Road, Belfast. He was the eldest child, with six brothers and one sister. At the start of the Troubles, his family was forced out of their home. He graduated from Trinity College, Dublin in 1973. One of his brothers, John, a Provisional Irish Republican Army (IRA) member, was killed in a car crash in the Falls Road in 1972. Another brother, Dermot, successfully contested attempts to extradite him to Northern Ireland from the Republic of Ireland for his part in the killing of a prison officer; he was one of 38 IRA prisoners who escaped from the Maze in 1983. A third brother Seamus was the fiancé of Mairead Farrell, one of the IRA trio shot dead by the Special Air Service (SAS) in Gibraltar in March 1988. Seamus was the leader of an IRA unit in west Belfast before his arrest in 1976 with Bobby Sands and seven other IRA men, during an attempt to destroy Balmoral's furniture store in south Belfast. He was sentenced to 14 years' imprisonment. Finucane's wife, Geraldine, whom he met at Trinity College, is the daughter of middle-class Protestants; together they had three children. His son John is a Sinn Féin politician who was elected as Lord Mayor of Belfast in May 2019.
 Passage 2:The Battle of Ia Drang was the first major battle between the United States Army and the People's Army of Vietnam (PAVN), also referred to as the North Vietnamese Army (NVA), and was part of the Pleiku Campaign conducted early in the Vietnam War. It comprised two main engagements, centered on two previously scouted helicopter landing zones (LZs), known as LZ X-Ray and LZ Albany. The first involved the 1st Battalion, 7th Cavalry Regiment and supporting units under the command of Lieutenant Colonel Hal Moore, and took place November 14–16, 1965 at LZ X-Ray, located at the eastern foot of the Chu Pong Massif in the central highlands of Vietnam. The second engagement involved the 2nd Battalion, 7th Cavalry Regiment plus supporting units under the command of Lieutenant Colonel Robert McDade, and took place on November 17 at LZ Albany, farther north in the Ia Drang Valley. It is notable for being the first large scale helicopter air assault and also the first use of Boeing B-52 Stratofortress strategic bombers in a tactical support role. Surrounded and under heavy fire from a numerically superior force, the American forces at LZ X-ray were able to hold off and drive back the North Vietnamese forces over three days of battle, largely through the support of both air power and heavy artillery bombardment, which the North Vietnamese lacked. LZ X-ray was considered an American tactical victory, as the Americans were able to exact an almost 10:1 kill ratio. At LZ Albany, the American forces were ambushed in close quarters. They were unable to use air and artillery support due to the close engagement of the North Vietnamese, the American forces were badly defeated, suffering an over-50% casualty rate before being extricated from the battle. Both sides, therefore, were able to claim victory in the battle.
 Passage 3:In 1995, the MLS began an expansion plan to add new teams to the league. In the 1996 MLS Inaugural Allocations, the MLS assigned Burns to the New England Revolution. In August 1995, the MLS loaned out Burns to Danish club Viborg FF. The Revolution retained his rights and Burns returned to play for the Revolution in 1996. In 1998, Burns earned a place in the MLS All-Star game. In the 1999 off-season, he made several attempts to move back to a European club, trying out with clubs such as Utrecht, Bolton and Hearts. None of the clubs expressed interest in him and Burns returned to the Revolution. In June 2000, the Revolution traded Burns, Dan Calichman and a first round draft pick to the San Jose Earthquakes in exchange for Mauricio Wright. Burns finished the 2000 season with the Earthquakes. However, he did not remain with the team and he was traded in March 2001 to the Kansas City Wizards in return for conditional picks in the 2002 MLS SuperDraft. Burns played two seasons with the Wizards, 2001 and 2002. In 2002, he was chosen to play in the 2002 MLS All-Star Game. At the end of the 2002 season, Burns announced his retirement from professional football.
