[EX Q]: Question: How long had Darrell Royal been working as a head coach the year he learned about the wishbone offense? Passage:In 1968, Texas head coach Darrell Royal and his offensive coordinator Emory Bellard introduced what would become known as the wishbone offense. The wishbone was derived from the Split-T offense run at Oklahoma under Bud Wilkinson. In the formation, the quarterback lines up with a fullback and two tailbacks behind him, and on any play may keep the ball, hand off to the fullback, or pitch to a tailback. From the time Bryant arrived at Alabama through the 1970 season, the Crimson Tide ran a pro-style offense. By 1969, Bryant began to recruit larger linemen and tailbacks, and after a pair of six win seasons in 1969 and 1970, Bryant saw the success of the wishbone for the Longhorns and decided to implement the offense for the 1971 season. In spring 1971, Alabama assistants Mal Moore and Jimmy Sharpe traveled to Austin where they saw first hand how the wishbone operated during Texas' final week of spring practice.

[EX Q]: Question: How many states seceded from the Union after Mississippi? Passage: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.
