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.

Let me give you an 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-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.

OK. solve this:
Question: How many casualties combined where in the two wars where the Bofors 37 mm anti-tank gun gained most of its fame from? Passage 1:The Bofors 37 mm anti-tank gun was an anti-tank gun designed by Swedish manufacturer Bofors in the early 1930s originally for Swedish use. It was exported to several countries during the 1930's of which several bought licences to produce it themselves. The gun was used in several conflicts but most of its fame comes from its use in the Spanish civil war and the Winter war where it was used very successfully against light tanks and armored cars among other targets. Beyond its use as an infantry gun it was also used as the main armament in several armored cars and tanks such as the Dutch M39 Pantserwagen and the Polish 7TP to name a few. As the armor of tanks was increased during World War II the gun very quickly became obsolete as an anti-tank gun but was still used effectively as an infantry support gun for the entirety of the war, and well into the Cold War. This was due to its high fire rate, great mobility and effective high explosive shells.
 Passage 2:The Arcore was designed at the Centro Volo a Vela (CVV), or Experimental Soaring Centre, of the Royal Polytechnic of Milan by Gildo Preti. It was the third glider to be designed and built there and had a close resemblance to the first of them, the CVV 1 Pinguino. Both were wood and fabric single seat competition gliders, cantilever monoplanes with mid-mounted gull wings. The wings in particular were very similar in all respects apart from the Arcore's greater span. They were built around a single spar, with a plywood covered D-box ahead of it and fabric behind. In plan, they had a constant chord centre section, filling about a third of the span, and outer sections with taper on both leading and trailing edges ending in semi-elliptical tips. The centre section had positive dihedral but there was none on the outer panels. Ailerons occupied the whole of these outer panels, hinged parallel to the trailing edge. Short span airbrakes extended upwards only, mounted just behind the spar at the outer ends of the centre section.

During this campaign Noyes was given command of the 3rd Battalion, consisting of Companies I and K of the 2nd U.S. Cavalry at the Battle of Powder River in Montana Territory. Upon returning to Fort Laramie, Noyes would be court-martialed for his actions during the battle in unsaddling his company and therefore rendering it unable to support the remainder of the command fighting in the village. He was found guilty on May 2, but allowed to rejoin his regiment and command a five-company battalion of the 2nd Cavalry during on Big Horn and Yellowstone Expedition from May 23 to October 28, 1876, being engaged in the Battle of Prairie Dog Creek on June 9 and the Battle of Rosebud on June 17, 1876.

Noyes served on Mounted Recruiting Service from October 1878 to September 30, 1879 and was promoted Major, 4th Cavalry effective June 14, 1879. He was in command of a battalion at Fort Garland, California from December 1, 1879 to March 12, 1880, of Fort Hays, Kansas until May 30, 1880, of a battalion in the field in New Mexico Territory until November 6, 1880, and again of Fort Hays, Kansas until July 20, 1881.
