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.

New input: Question: In what city was Watson a laboratory staff member from 1957 to 1981? Passage 1:Watson graduated in 1943 with BS in electrical engineering from Iowa State College. From 1943 to 1946 he was a researcher at the United States Naval Research Laboratory in Washington, D.C. During his work for the U.S. Navy he went to night school at George Washington University. He graduated from the University of Iowa with Ph.D. in 1948 with thesis The polarizability of the meson-charge cloud of a neutron in an external electrostatic field. He was from 1948 to 1949 an Atomic Energy Commission (AEC) Fellow at the Institute for Advanced Study and from 1949 to 1951 an AEC Fellow at the Berkeley Radiation Laboratory. He was from 1951 to 1954 an assistant professor of physics at Indiana University and from 1954 to 1957 an associate professor of physics at the University of Wisconsin, Madison. In 1953 he was elected a fellow of the American Physical Society. From 1957 to 1981 he was a staff member of Lawrence Berkeley National Laboratory, as well as a professor of physics at the University of California, Berkeley. In 1974 he was elected a member of the National Academy of Sciences. From 1981 to 1991 he was the director of the Marine Physical Laboratory, Scripps Institute of Oceanography, as well as a professor of physical oceanography at the University of California, San Diego. In 1991 he retired as professor emeritus. His doctoral students include Shang-keng Ma.
 Passage 2:Krul returned to Newcastle as backup to first choice Steve Harper. He made his senior league debut on 8 August 2009 in the opening Football League Championship game of the season away to West Bromwich Albion, coming on as a half time substitute for the injured Harper. Following this match, The Guardian called him "an excellent reserve goalkeeper". He later played the full Football League Cup match against Huddersfield Town on 26 August 2009, which Newcastle won 4–3. Krul also started the 2–0 League Cup defeat to Peterborough. Against Swansea City on 28 November, he again came on to replace the injured Steve Harper. On 2 January, he played in the FA Cup Third Round tie against Plymouth Argyle, the game ending 0–0. He then played in the replay at St James' Park on 13 January, a 3–0 victory. Krul started his first league game for Newcastle on 2 May 2010, the last day of the Championship campaign, against Queens Park Rangers at Loftus Road and kept a clean sheet. In July 2010, Krul signed a new four-year contract with Newcastle.
 Passage 3:In 1909, Alois Hitler Jr. met an Irishwoman by the name of Bridget Dowling at the Dublin Horse Show. They eloped to London and married on 3 June 1910. William Dowling, Bridget's father, threatened to have Alois arrested for kidnapping, but Bridget dissuaded him. The couple settled in Liverpool, where their son William Patrick Hitler was born in 1911. The family lived in a flat at 102 Upper Stanhope Street. The house was destroyed in the last German air-raid on Liverpool on 10 January 1942. Nothing remains of the house or those that surrounded it, and the area was eventually cleared and grassed over. Bridget Dowling's memoirs claim Hitler lived with them in Liverpool from 1912 to 1913 while he was on the run to avoid being conscripted in his native Austria-Hungary, but most historians dismiss this story as a fiction invented to make the book more appealing to publishers. Alois attempted to make money by running a small restaurant in Dale Street, a boarding house on Parliament Street and a hotel on Mount Pleasant, all of which failed. Alois Jr. left his family in May 1914 and he returned alone to the German Empire to establish himself in the safety-razor business.
