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.

Question: How many teams are currently in the conference that Buckeyes was in during the 2006-2007 season? Passage 1:Andriy Shevchenko is a former professional association footballer who represented the Ukraine national football team as a striker for 17 years from 1995 to 2012. He is the Ukrainian national football team's top goalscorer with 48 goals in 111 appearances, making him the 2nd most capped Ukrainian international behind Anatoliy Tymoshchuk (144). He has represented the nation in two international tournaments: the 2006 FIFA World Cup and the 2012 UEFA European Championship. He has also played for them during every qualifying campaign during his international career. He made his debut for his country in a 4–0 loss to Croatia in March 1995 during a UEFA Euro 1996 qualifying match. However, he would not score his first goal until May 1996 in a friendly against Turkey. He scored his final goal for his country in the 55th minute of a UEFA Euro 2012 group stage match against Sweden. Ukraine would win the game 2–1. He decided to retire from international football after their final match in the group stage, which was against England. It ended with a 1–0 loss for the Ukraine. 
 Passage 2:The usual English spelling in Ireland since the Gaelic revival is Connacht, the spelling of the disused Irish singular. The official English spelling during English and British rule was the anglicisation Connaught, pronounced or . This was used for the Connaught Rangers in the British Army; in the title of Queen Victoria's son Arthur, Duke of Connaught; and the Connaught Hotel, London, named after the Duke in 1917. Usage of the Connaught spelling is now in decline. State bodies use Connacht, for example in Central Statistics Office census reports since 1926, and the name of the Connacht–Ulster European Parliament constituency of 1979–2004, although Connaught occurs in some statutes. Among newspapers, the Connaught Telegraph (founded 1830) retains the anglicised spelling in its name, whereas the Connacht Tribune (founded 1909) uses the Gaelic. Connacht Rugby who represent the region and are based in Galway, use the Gaelic spelling also.
 Passage 3:The Ohio State Buckeyes were the No. 1 ranked team for the entire 2006 NCAA Division I FBS football season, anchored by Heisman Trophy winning quarterback Troy Smith. The Buckeyes were 12–0 with several wins over ranked opponents: the defending national champions, then No. 2 Texas Longhorns, then No. 24 Penn State Nittany Lions, then No. 13 Iowa Hawkeyes, and their then undefeated Big Ten Conference rival, then No. 2 Michigan. The win over Michigan to finish the regular season essentially guaranteed the Buckeyes a spot in the National Championship game. Who they would play remained a highly debated question. Despite the loss to Ohio State, Michigan remained No. 2 in the polls, followed by No. 3 Southern California (USC), No. 4 Florida, and No. 5 Notre Dame.
