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-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.

Q: Question: Which schools split from the Southern Conference to form the Atlanti Coast Conference in 1953. Passage 1:Roxas' first appearances were cameos in Another Side, Another Story, a bonus trailer found in Kingdom Hearts, and in the ending of . In Kingdom Hearts II, Roxas is introduced as a boy living in a computer simulation of a city called Twilight Town. Unaware of the virtual nature of the city, Roxas begins to dream about the adventures of Sora, the series' protagonist. He later encounters Axel, a member of Organization XIII who is under orders to extract him, and Namine, a Nobody who tells him he is Sora's other half. Shortly after meeting DiZ, the creator of the virtual world, Roxas learns the true nature of Twilight Town, and that DiZ altered his memory and personality to mislead his pursuers from the Organization until he can merge with Sora. DiZ leads Roxas to an old mansion where he rejoins a sleeping Sora, allowing him to wake up. Sora later learns that Roxas is his Nobody, created during the events of the first game after briefly turning into a Heartless, and inducted into the Organization for his ability to capture hearts with the Keyblade; however, Roxas later betrayed the Organization and encountered one of Sora's friends, Riku, who captured him to restore Sora. Roxas makes two appearances near the end of the game: the first is in a mental battle with Sora depicted as a cut-scene, and the second is with Namine, who has merged with her other self, Kairi. In the re-released version of the title, Kingdom Hearts II Final Mix, Roxas' fight against Sora is expanded, making him a boss character. The battle was meant to be interactive in Kingdom Hearts II, but time constraints imposed from creating fights for the other Organization XIII members prevented its inclusion. With the opportunity to include the fight, Nomura's team worked hard to make it entertaining for players. Additional scenes about Roxas' past were included in the game to add to the mystery around him.
Passage 2:Hoadley made his first-class debut for Sussex against Warwickshire in the 1975 County Championship. He made six further first-class appearances for the county, the last of which came against Kent in the 1976 County Championship. In his seven first-class matches, he scored a total of 202 runs at an average of 18.36, with a high score of 58. This score was one of two fifties he made and came against Hampshire in 1975. Hoadley also made three List A appearances for Sussex in the 1975 John Player League against Warwickshire, Nottinghamshire and Kent. He scored just 13 runs at an average of 6.50, with a high score of 8 in these three matches.
Passage 3:The Terrapins won the 1951 Southern Conference co-championship alongside the Virginia Military Institute. Their perfect season culminated with an upset over first-ranked Tennessee in the . At the time, however, the wire services released their final rankings before the bowl games, and Maryland finished third in the Associated Press Poll. Several selectors, including analyst Jeff Sagarin, have retroactively credited Maryland with the national championship. In 1953, Maryland and six other schools split from the Southern Conference to form the Atlantic Coast Conference. That year, Maryland shut-out two 11th-ranked teams: Mississippi, 380, and Alabama, 210, won the ACC co-championship alongside Duke, and were named the national champions as the only undefeated and untied team in the nation. The Terrapins were defeated by fourth-ranked Oklahoma in the Orange Bowl. After the 1955 season, Tatum resigned to return to North Carolina, where he soon died of Rocky Mountain spotted fever.
