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: How old was George Rákóczi when he was defeated by Gabriel Bethlen's forces at the Battle of Humenné? Passage 1:At the time, the Thirty Years' War was raging across Europe. Gabriel Bethlen, prince of Transylvania saw an opportunity to unite the two Hungarian principalities, Transylvania and Royal Hungary, and sacked Vienna in November 1619. He also asked Sultan Osman II for aid, but this was unsuccessful. The Commonwealth was relatively uninvolved in this war but the Polish king, Zygmunt III Waza, sent an elite and ruthless mercenary unit, the Lisowczycy, to aid his Habsburg allies. They defeated the Hungarian lord George Rákóczi at the Battle of Humenné in 1619, and thus, cut the supply lines of Transylvanian forces. Then Gaspar Graziani, ruler of Moldavia, switched sides and joined Poland.
 Passage 2:John Cooke was baptised on 5 March 1762 at St. Mary, Whitechapel, the second son of Francis Cooke, an Admiralty clerk, and his wife Margaret. John Cooke first went to sea at the age of eleven aboard the cutter under Lieutenant John Bazely, before going ashore to spend time at Mr Braken's naval academy at Greenwich. He was entered onto the books of one of the royal yachts by Sir Alexander Hood, who would become an enduring patron of Cooke's. In 1776 he obtained a position as a midshipman on the ship of the line , aged thirteen. Cooke served aboard Eagle, the flagship of the North American Station, during the next three years, seeing extensive action along the eastern seaboard. Notable among these actions were the naval operations around the Battle of Rhode Island in 1778, when Eagle was closely engaged with American units ashore. He distinguished himself in the assault, causing Admiral Lord Howe to remark "Why, young man, you wish to become a Lieutenant before you are of sufficient age." On 21 January 1779, Cooke was promoted to lieutenant and joined in the East Indies under Sir Edward Hughes, but was forced to take a leave of absence due to ill-health.
 Passage 3:Harwood was born in Barton Seagrave, a suburb of Kettering, but grew up in Yorkshire. She attended Skipton Girls' High School. Her parents were both musical, and her mother, a professional soprano, taught her singing. Harwood later said of her childhood, "My mother sang under the name Constance Read, and she did quite a bit of early broadcasting from Birmingham. When she had her children – there were three of us – she did local singing and took up her teaching. My father, in the Methodist Chapel tradition, did a good deal of conducting". Harwood continued her studies at the Royal Manchester College of Music from 1956. In 1957, for the Buxton Opera Group, she sang Michaela in Passion Flower, an adaptation of Carmen. In a student production of Massenet's Werther in 1958, she won praise as Sophie. At the age of 21, she won the Kathleen Ferrier Memorial Scholarship and spent a year in Milan studying with Lina Pagliughi. She was later a joint winner of the international Verdi competition in Busseto.
