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-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.

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

New input: Question: Is the Prime Minister who won the election in 1979 still alive today? Passage 1:Trudeau lived at 24 Sussex Drive, Ottawa, the official residence of Canada's prime minister, from his birth until his father's government was defeated in the federal election on May 22, 1979. The Trudeaus were expected to move into the residence of the Leader of the Official Opposition, Stornoway, at 541 Acacia Avenue in Rockcliffe Park, but because of flooding in the basement, prime minister Joe Clark offered them Harrington Lake, the prime minister's official country retreat in Gatineau Park, with the expectation they would move into Stornoway at the start of July. However, the repairs were not complete so Pierre Trudeau took a prolonged vacation with his sons to the Nova Scotia summer home of his friend, MP Don Johnston, and later sent his sons to stay with their maternal grandparents in North Vancouver for the rest of the summer while he slept at his friend's Ottawa apartment. Justin and his brothers returned to Ottawa for the start of the school year, but lived only on the top floor of Stornoway while repairs continued on the bottom floor. His mother purchased and moved into a new home nearby at 95 Queen Victoria Avenue in Ottawa's New Edinburgh in September 1979. The Trudeaus returned to the prime minister's official residence in February 1980 after the election that returned his father to the Prime Minister's Office.
Passage 2:From 1805 onwards, Ruty took part to the campaigns of the Grande Armee during the War of the Third Coalition and War of the Fourth Coalition, serving as artillery park director for the Army Corps of Marshal Michel Ney, then Marshal Joachim Murat. A brigadier general from 1807, he served with distinction at the battle of Friedland. In 1808 he was created a baron of the Empire, serving as commander of the artillery school in Toulouse, before being sent to serve in Spain, towards the end of that year. He contributed significantly to the successful sieges of Ciudad Rodrigo and Almeida, before taking command of Marshal Jean-de-Dieu Soult's artillery in the armies of the South and of Andalusia. During this campaign he invented a type of howitzer that bears his name. In 1813, Ruty was recalled to France, and promoted to general of division, before being named commander of Marshal Nicolas Oudinot's Corps artillery during the Saxon campaign of the War of the Sixth Coalition. In November 1813, Ruty was created a count of the Empire. After Napoleon's abdication in 1814, Ruty served the Bourbon Restoration, but during the Hundred Days he joined the Emperor, who named him commander of the artillery of the Army of the North, with Ruty playing a significant role at the battle of Waterloo. General count de Ruty finished his military career as general inspector for artillery during the Second Restoration, subsequently serving as general director for gunpowders and saltpeter (1817), state counsellor (1818) and Peer of France from 1819.
Passage 3:As a British colony, and with immigration no longer limited to members of the Roman Catholic religion, the city began to grow from British immigration. American Revolutionists under General Richard Montgomery briefly captured the city during the 1775 invasion of Canada but left when it became obvious they could not hold Canada. Often having suffered loss of property and personal attacks during hostilities, thousands of English-speaking Loyalists migrated to Canada from the American colonies during and after the American Revolution. In 1782, John Molson estimated the population of the city at 6,000. The government provided most with land, settling them in what became Upper Canada (Ontario) to the west, as well as Nova Scotia and New Brunswick to the east. The first Protestant church in Montreal was St. Gabriel's, established by a Presbyterian missionary in 1792. With 19th-century immigration, more and more English-speaking merchants and residents continued to arrive in what had by then become known as Montreal. Soon the main language of commerce in the city was English. The golden era of fur trading began in the city with the advent of the locally owned North West Company, the main rival to the primarily British Hudson's Bay Company. The first machine shop in Montreal, owned by one George Platt, was in operation before 1809. The census of 1821 numbered 18,767 residents.
