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 much time were there between the end of the failed Market Garden operation and the beginning of the new allied offensive near the Belgian-Dutch border? Passage 1:The royal election of 1764 resulted in the elevation of Stanisław August Poniatowski, a refined and worldly aristocrat connected to a major magnate faction, but hand-picked and imposed by Empress Catherine II of Russia, who expected Poniatowski to be her obedient follower. The King accordingly spent his reign torn between his desire to implement reforms necessary to save the state, and his perceived necessity of remaining in subordinate relationship with his Russian sponsors. The Bar Confederation of 1768 was a szlachta rebellion directed against Russia and the Polish king, fought to preserve Poland's independence and in support of szlachta's traditional causes. It was brought under control and followed in 1772 by the First Partition of the Commonwealth, a permanent encroachment on the outer Commonwealth provinces by the Russian Empire, the Kingdom of Prussia and Habsburg Austria. The "Partition Sejm" under duress "ratified" the partition fait accompli. In 1773 the Sejm established the Commission of National Education, a pioneering in Europe government education authority.
 Passage 2:The 2017–18 Providence Friars men's basketball team represented Providence College in the 2017–18 NCAA Division I men's basketball season. The Friars, led by seventh-year head coach Ed Cooley, played their home games at the Dunkin' Donuts Center as members of the Big East Conference. They finished the season 21–14, 10–8 in Big East play to finish in a three-way tie for third place. As the No. 5 seed in the Big East Tournament, they defeated Creighton and No. 1-seeded Xavier in back-to-back overtime games to advance to the championship game. In a third straight overtime game, the Friars fell to Villanova in the championship game. They received an at-large bid to the NCAA Tournament as the No. 10 seed in the West region where they lost to Texas A&M in the First Round.
 Passage 3:Joining the Battle of Hürtgen Forest, the division moved into defensive positions in the vicinity of Wuustwezel, Belgium on 23 October 1944. The Timberwolves were then assigned to British Field Marshal Bernard Montgomery's Anglo-Canadian 21st Army Group under the British I Corps, along with the U.S. 7th Armored Division, in order to clear out the Scheldt Estuary and open the port of Antwerp. While the U.S. 7th Armored Division was assigned static duty holding the right flank of the gains made during the failed Market Garden operation, the 104th Infantry Division was to assist the First Canadian Army in the taking of the Scheldt. The Timberwolves travelled across France by train and debarked near the Belgian-Dutch border and waited for word to take part in a new allied offensive, Operation Pheasant, taking the place of the experienced British 49th Infantry Division on the left flank and the Polish 1st Armored Division on the right.
