Given the task definition, example input & output, solve the new input case.
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.
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-Lo 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 (18941973) 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 case for you: Question: How many months after the Piccadily line was created did it join with the London Underground's District line? Passage 1:The original catalyst for development was the ill-fated vanity project by Lord Kensington (died 1852) which consisted of the two-mile conversion of the insanitary Counter's Creek into the Kensington Canal (1826 onwards), followed by its eventual replacement first by "Mr Punch's railway", opened in 1844 and next, by the Metropolitan District Railway in 186569, which eventually became London Underground's District Line and was joined after 1907 by the Piccadilly line. Meanwhile, the congestion apparent in London and Middlesex for burials at the start of the century was causing public concern not least on health grounds. In 1837 a decision was made to lay out a new burial ground on the edge of Earl's Court in an outlying area of Brompton. The moving spirit behind the project was the engineer, Stephen Geary. It was necessary to form a company in order to get parliamentary permission to raise capital for the proposal. Securing the land some 40 acres from local landowner, Lord Kensington and the Equitable Gas Light Company, as well as raising the money proved an extended challenge. After two years the cemetery was duly established by Act of Parliament and laid out in 1839, it opened in 1840, originally as the West of London and Westminster Cemetery. It was consecrated by Charles James Blomfield, Bishop of London in June 1840, and is now one of Britain's oldest and most distinguished garden cemeteries, served by the adjacent West Brompton station.
Passage 2:Bonko first sought political office in the 1995 municipal election, when he was elected to the Board of Edmonton Public Schools as trustee for Ward A. He was re-elected in the 1998 and 2001 elections. He did not seek re-election at the conclusion of his third term. Instead, he ran for the Legislative Assembly of Alberta in Edmonton Decore in the 2004 provincial election as a Liberal. He won 44.63% of the vote and defeated his opponents, who included former MLA Walter Szwender who was running for the Progressive Conservatives and Gary Masyk, an incumbent MLA whose riding had been abolished and who had crossed the floor to become the Alberta Alliance's first MLA after being elected as PC. He did not sponsor any bills during his time in the legislature, and was defeated by Progressive Conservative candidate Janice Sarich in the 2008 election.
Passage 3:With the outbreak of the Civil War, Weed was promoted captain of the newly formed Battery I, 5th U.S. Artillery in May 1861. He remained at Camp Curtin in Harrisburg, Pennsylvania, training his crews until the spring of 1862, when they served in the Peninsula Campaign and at Second Bull Run. He commanded his battery during the fierce artillery duel at Antietam. Promoted to command of all the artillery of the V Corps, his guns were in action at the Battle of Fredericksburg. From December 1862 through January 1863, he was stationed at Falmouth, Virginia. After a short leave of absence, he took part in the Battle of Chancellorsville, commanding the artillery of the 2nd Division, V Corps. On June 6, 1863, Weed left the regular army artillery to accept a commission as a brigadier general in the volunteer army. He was assigned command of 3rd Brigade in the 2nd Division, V Corps.
