You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.

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

New input: Question: Where did the man who discovered Bundgaard's artistic talents work? Passage 1:Adams was active in rioting at this time and later became involved in the republican movement. In August 1971, internment was reintroduced to Northern Ireland under the Special Powers Act 1922. Adams was interned in March 1972, on , but on the Provisional IRA's insistence was released in June to take part in secret, but abortive talks in London. The IRA negotiated a short-lived truce with the British government and an IRA delegation met with British Home Secretary William Whitelaw at Cheyne Walk in Chelsea. The delegation included Adams, Martin McGuinness, Sean Mac Stiofain (IRA Chief of Staff), Daithi O'Conaill, Seamus Twomey, Ivor Bell and Dublin solicitor Myles Shevlin. Adams was re-arrested in July 1973 and interned at the Long Kesh internment camp. After taking part in an IRA-organised escape attempt, he was sentenced to a period of imprisonment. During this time, he wrote articles in the paper An Phoblacht under the by-line "Brownie", where he criticised the strategy and policy of Sinn Féin president Ruairí Ó Brádaigh and IRA Belfast OC Billy McKee. He was also highly critical of a decision taken by McKee to assassinate members of the rival Official IRA, who had been on ceasefire since 1972. 
 Passage 2:When Bundgaard arrived in Copenhagen, he undertook a variety of odd jobs until his artistic talents were discovered by Emil Blichfeldt who encouraged him to attend the Technical School in 1884 and later the Danish Academy. It was there that he was introduced to French Naturalism by Stephan Sinding, giving his works with a rather dramatic touch. A stay in Paris also provided him with inspiration from Jules Dalou, Alexandre Falguière and Auguste Rodin. In addition, his father's interest in mythology and folk tales reinforced his imaginative approach which can be seen in his robust, Naturalistic works, often made of granite. His interest in ecclesiastical art from the Middle Ages is also apparent. Bundgaard undertook several major decorative projects including sculptures for the recently built Copenhagen City Hall (1894–99) and for Christiansborg Palace (1907–28) where his four majestic figures stand over the entrance to the parliamentary chamber. Bundgaard's works often exhibit a mythological, nationalistic slant as can be seen in two of his masterpieces, the Gefion Fountain (1908) on Copenhagen's waterfront and the Cimbrian Bull (1937) in Aalborg. He also completed a number of monuments in commemoration of the volunteers from 1848 and 1864 as well as the Reunification Monument in Randers. Many of Bundgaard's original plaster models can be seen in the Thingbæk Kalkminer Museum, a former mine near the Rebild National Park.
 Passage 3:Diana Beck was born in 1900 in Hoole, Chester, to James Beck, a tailor, and Margaret Helena Kinloch. She attended The Queen's School before studying medicine at the London School of Medicine for Women, where she won two prizes and a scholarship. After graduating in 1925, she worked at the Royal Free Hospital as a house surgeon and then a surgical registrar throughout the 1930s. She chose to specialise in neurosurgery and trained under Hugh Cairns at the Radcliffe Infirmary in Oxford, where she also acted as a general surgeon providing treatment to injured soldiers during the war. In 1939, she was awarded the William Gibson Research Scholarship for Medical Women by the Royal Society of Medicine, and used the grant to undertake research in Oxford with Dorothy Stuart Russell. Using animal experiments, they investigated the causes of idiopathic intracranial hypertension and experimented with various graft materials for cranioplasty.
