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: Which North American city hall building that used Superblocks was completed first? Passage 1:Rudd was probably born in North Yorkshire 1794 or 1795. He studied at St John's College, Cambridge where he got a B.A. before 1818 and a M.A. before 1821. He was ordained as deacon in 1818 and as priest in 1819 by John Fisher. He served as curate at Horsted Keynes (West Sussex) from 1818, at Shipton Bellinger (Hampshire) from 1819, and at Kimpton (Hampshire) from 1821. In 1833 he was appointed vicar of Sockburn (North Yorkshire), where he lived for a number of years at Worsall Hall near Yarm. His captures of beetles are mentioned by James Francis Stephens, John Curtis and Alexander Henry Haliday and he collected insects with George Samouelle. Rudd published six notes on insects in the Entomologist’s Magazine  and other journals between 1834 and 1846 some of which dealt with beetles. The last described Haltica dispar as a new species. (Zoologist, 4, 1846, p. 1517). He was a fellow of the Linnean Society and in 1833, he was a founder of the Entomological Society of London, later Royal Entomological Society. He died on 4 March 1847 in London at the age of 52.
 Passage 2:In the U.S., the northernmost is Martha's Diner in Coventry, Vermont. The Miss Wakefield, originally Pat & Bob's in Albany, New York, was built in 1949, rescued from a junkyard there, and trucked to a new home in Sanbornville, New Hampshire. The Summit Diner, a 1938 model, is located in Summit, New Jersey. The oldest Southern diner (non–stainless steel style) is believed to be the Hillsville Diner in Carroll County, Virginia. The Triangle Diner, a 1948 stainless steel O'Mahony original model, is located in the old town of Winchester, Virginia, and is being historically restored to how it appeared in 1948. The Triangle Diner is the oldest stainless steel style O'Mahony diner in Virginia. In 2007 Tommy's Deluxe Diner was moved from Middletown, Rhode Island, to Oakley, Utah, where it opened as the Road Island Diner. One of the original ones displayed at the 1939 New York World's Fair, made by Paramount Diners, is still in operation as the White Mana in Jersey City. Also in Jersey City is the Miss America, a 1942 classic stainless steel model, located next to the New Jersey City University campus. The Shawmut Diner of New Bedford, Massachusetts was donated by its owners to the Bristol County House of Corrections in Dartmouth, Massachusetts and will serve as a training facility for inmates. TJ's (formerly the Point Diner) in Tamaqua, Pennsylvania is a 1940 O’Mahony diner, although its exterior has been renovated and no longer has the stainless metal-look exterior. The diner is located within the Tamaqua Historic District.
 Passage 3:Superblocks are also used when functional units such as rail yards or shipyards, inherited from the 19th and early 20th centuries, are too big to fit in an average city block. A contemporary function which reflects ancient practices that also requires larger than typical blocks is the sports stadium or arena. Just as the Colosseum in ancient Rome, sports complexes require superblocks. The Providence Park stadium in Portland, for example, takes up four normal city blocks as does the equally large Greensboro Coliseum in North Carolina. Other contemporary institutions, establishments or functions that use superblocks are: city halls like Government Center, Boston and Toronto City Hall; regional general hospitals or specialized medical centres; convention and exhibition centers, such as Exhibition Place in Toronto and the Boston Convention and Exhibition Center; and downtown enclosed Shopping Malls such as Eaton Centre in Toronto, echoing the large gallerias of the 19th century. Cultural complexes, such as the Lincoln Center in New York City, often occupy a superblock achieved through the consolidation of regular city blocks. A recent superblock user is the merchandise distribution centre, which can range in area from one to ten city blocks.
