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.
Q: Question: Who is the governor of the state that was admitted to the union in 1818? Passage 1:Serco operates the Santander Cycles scheme (for Transport for London) and the NorthLink Ferries Northern Isles lifeline ferry service in Scotland. Serco also has a joint venture with Abellio, the international arm of Dutch national rail operator Nederlandse Spoorwegen, to operate passenger trains in the UK. Serco-Abellio has a 25-year concession for Merseyrail in Liverpool until 2028 and operated the Northern Rail franchise from December 2004 until March 2016. Serco's Home Affairs division, run by Tom Riall, also operates speed camera systems throughout the UK and, until November 2013, designed, wrote and tested the software that controls the matrix message signs, signals, emergency roadside telephones (SOS) and traffic monitoring on England's motorway network including, until 2011, the National Traffic Control Centre. It previously operated the Docklands Light Railway.
 Passage 2:The abbey was founded in 1147 as a daughter house of Clairvaux by Robert, Earl of Gloucester, and was dedicated to the Blessed Virgin Mary. Early Christian crosses found in the close vicinity and conserved in the nearby Margam Stones Museum suggest the existence of an earlier Celtic monastic community. The founding abbot was William of Clairvaux. The third abbot, Conan, enjoyed the praise of Giraldus Cambrensis, whom he appears to have entertained prior to his official visit with Baldwin of Forde, Archbishop of Canterbury, to preach the Crusade in 1188. Conan (or Cunan) contributed to Patristic literature, as he is credited with the capitula or chapter-headings prefixing each section of St. Bernard's Sermons on the Song of Songs, one of the works for which that author was titled a Doctor of the Church.
 Passage 3:The U.S. state of Wisconsin is divided into 72 counties. The land that eventually became Wisconsin was transferred from British to American control with the 1783 signing of the Treaty of Paris. It was an unorganized part of the Northwest Territory until 1802 when all of the land from St. Louis north to the Canadian border was organized as St. Clair County. When Illinois was admitted to the union in 1818, Wisconsin became part of the Territory of Michigan and divided into two counties: Brown County in the northeast along Lake Michigan and Crawford County in the southwest along the Mississippi River. Iowa County was formed in 1829 from the Crawford County land south of the Wisconsin River. Brown County's southern portion was used to form Milwaukee County in 1834. The state of Wisconsin was created from Wisconsin Territory on May 29, 1848, with 28 counties.
