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 input: 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.

Q: Question: Which school charged more to attend the year Larson got her B.A., Columbia University or Southern Illinois University? Passage 1:Henrietta Melia Larson was born in Ostrander, Minnesota on 24 September 1894, sister of Agnes Larson. She received her B.A. from St. Olaf College in 1918 and taught one year of high school before she became an instructor at Augustana College in 1921–22. She studied at the University of Minnesota in 1922–24, then taught at Bethany College from 1925 to 1926. Larson received her Ph.D. from Columbia University and The Wheat Market and the Farmer in Minnesota, 1858–1900 in 1926. She then taught at Southern Illinois University in 1926–28 before she became a research associate at the Harvard University Graduate School of Business Administration in 1928. Together with N. S. B. Gras, she wrote Jay Cooke, Private Banker in 1936 and she was the editor of the Bulletin of the Business Historical Society in 1938. They compiled the Casebook in American Business History in 1939 and Larson was promoted to assistant professor that same year. She became the first woman to be appointed associate professor in the Graduate School of Business in 1942. Six years later, she wrote the Guide to Business History with Kenneth Wiggins Porter and she became associate editor of the Harvard Studies in Business History and then editor two years later. Larson was the senior author of the History of Humble Oil and Refining Company and History of Standard Oil Company (New Jersey), Vol. 3: New Horizons, 1927–1950, together with Evelyn H. Knowlton and Charles S. Popple. She was appointed professor of business history in 1960 and retired the following year. Larson died on 25 August 1983.
 Passage 2:Another great collaboration was with Asha Bhonsle. She has sung many hits under their baton. "Dhal Gaya Din" (with Rafi) in Humjoli (1970) became a superhit. "Roz Roz Rozy" from Khilona (1970), "Bane Bade Raja" from Abhinetri (1970), "Hungama Ho Gaya" and "Balma Hamar Motorcar Leke Aayo" from Anhonee  (1974), "Aye Mere Nanhe Gulfam" from Jagriti (1977), "Aaiye Shauk Se Kahiye" from Parvarish (1977), "Teri Rab Ne" from Suhaag (1979), "Ek Hasina Thi" from Karz (1980), "Are Bhaago Are Dauro" from Bandish (1980), "Man Kyun Behka Re" from Utsav (1985), "Balram Ne Bahut Samjhaya" from Ram Balram (1990) etc. They recorded the second most songs with Asha Bhosle. In the years 1980-1986, most of their songs would be sung by Asha only. "Hungama Ho Gaya" from Anhonee was a chartbuster and Asha was nominated for Filmfare Award in 1974. The song was later re-recorded for the 2014 film Queen, with additional voice by Arijit Singh, it again hit the top charts and became a superhit. "Man Kyun Behka Re" with Lata was also a hit and several blockbusters by L-P had Asha as lead voice in films such as Suhaag, Vakil Babu, Dostana, Adha Din Adhi Raat, Loha and Anhonee etc. to name a few.
 Passage 3:Ross and Bonnett were subsequently promoted at Disney, along with others from the Disney Channel, and credited for Hannah Montana’s broad reaching success across TV, music, and live tours, the model first proposed and put into motion by Roundhouse producers at Nickelodeon, but blocked by the network during the time Ross and Bonnett were there. That decision turned out to be shortsighted by Nickelodeon, and when proposed again to the then underutilized Disney Channel as a tie-in to the underperforming Hollywood Records (Disney Music Group), the concept proved inherently valuable enough that, as the complaint filed against Disney in 2007 in Los Angeles claimed, Rock and Roland was misappropriated by Disney and produced under the name Hannah Montana. For their key roles in bringing Hannah Montana to Disney, Rich Ross was elevated from the Disney Channel to Chairman of Walt Disney Studios in October 2009, forced to resign April 2012, and Adam Bonnett upped to Senior Vice President, Original Programming, Disney Channel.
