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.

Question: What was the reason Sullivan's success ballet was written and performed in 1897? Passage:When the Gilbert and Sullivan partnership collapsed after the production of The Gondoliers in 1889, their producer Richard D'Oyly Carte struggled to find successful new works to show at the Savoy Theatre. Carte produced Sullivan's grand opera, Ivanhoe at another theatre, and afterwards, he turned to Sullivan to create more comic operas for the Savoy. With Sydney Grundy, Sullivan wrote the nostalgic and sentimental Haddon Hall (1892) then, reunited with W. S. Gilbert, he produced Utopia, Limited (1893). He next returned, with his earlier collaborator F. C. Burnand, with The Chieftain (1894) and collaborated for the last time with Gilbert on The Grand Duke (1896). None of these had proved to be more than modestly successful, and Carte's other new pieces for the Savoy in the 1890s had done no better. Following the success of Sullivan's ballet Victoria and Merrie England in 1897, Carte asked Sullivan to work on another new opera for the Savoy.
