Detailed Instructions: 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.
Problem:Question: Who was the head coach for Ohio State Buckeyes when they were ranked No. 1 NCAA Div 1 team in 2006-2007? Passage 1: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.
 Passage 2: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 3: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.
