Q: 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.
Question: What state was admitted to the Union just before Mississippi? Passage 1:U.S. Route 13 runs north-south through the eastern part of Camden, heading north toward Dover and south toward Salisbury. U.S. Route 13 Alternate passes north-south through the center of Camden on Main Street. Delaware Route 10 runs east-west through Camden on Camden-Wyoming Avenue, heading west through rural western Kent County to the Maryland border and east toward Dover Air Force Base. DART First State provides bus service to Camden along Route 104, which runs from the Walmart in Camden north to the Dover Transit Center in Dover and connects to other local bus routes serving the Dover area; Route 117, which runs from the Walmart in Camden south to Harrington; and Route 303, which heads north to Dover and south to Georgetown.
 Passage 2:To escape the persecution of the Spanish Inquisition, Simon fled to Portugal, and remained for a time at Marialva, and also in the vicinity of Villa-Flor. Not feeling safe in Portugal, he went to Algeria. Miguel went to Italy and dwelt for a time at Nice, France, where his paternal aunt was married to the otherwise unknown Abraham de Torres. He then stayed for a longer time at Livorno, where another sister of his father, the wife of Isaac Cohen de Sosa, prevailed upon him to declare himself publicly a Jew. Soon after this he married Deborah Vaez, a relative of his brother-in-law, Eliahu Vaez, from Algeria, and afterward determined to leave Europe. On 20 July 1660, he, with 152 coreligionists and fellow-sufferers set sail for the West Indies. Soon after his arrival at Tobago his young wife died, and he returned to Europe. He went to Brussels and there entered the military service of Spain.
 Passage 3:On December 10, 1817, Mississippi became the 20th state admitted to the Union. By 1860, Mississippi was the nation's top cotton producing state and enslaved persons accounted for 55% of the state population. Mississippi declared its secession from the Union on March 23, 1861, and was one of the seven original Confederate States. Following the Civil War, it was restored to the Union on February 23, 1870. Until the Great Migration of the 1930s, African Americans were a majority of Mississippi's population. Mississippi was the site of many prominent events during the American Civil Rights movement, including the 1962 Ole Miss riots, the 1963 assassination of Medgar Evers, and the 1964 Freedom Summer murders. Mississippi frequently ranks low among states in measures of health, education, and development, and high in measures of poverty. In 2010, 37.3% of Mississippi's population was African American, the highest percentage for any state.
