Example Input: Question: Has the Wonder World Tour recording artist ever won a Grammy? Passage:The Wonder World Tour was the second concert tour by American recording artist Miley Cyrus. The tour was held to promote her second studio album Breakout (2008) and first extended play (EP) The Time of Our Lives (2009). It began in September 2009 and concluded in December 29, visiting cities in the United States and United Kingdom; thus, the Wonder World Tour became Cyrus' first world tour. It also became Cyrus' first tour not to incorporate performances as Hannah Montana, although "Let's Get Crazy", an official Hannah-song, was performed. Alternative band Metro Station served as opening act for all tour venues. It was sponsored by Wal-Mart and promoted by AEG Live. All tickets from the Wonder World Tour were sold using paperless ticketing, in order to prevent ticket scalping similar to what had occurred during Cyrus' previous tour. One dollar from each ticket sold was donated to the City of Hope National Medical Center, an organization devoted to the fight against cancer.

Example Input: Question: In the two 1973 movies that Fred Williamson starred in, which one made more money? Passage:Williamson's early film work included roles in M*A*S*H (1970) and Tell Me That You Love Me, Junie Moon (1970). He portrayed an escaped slave who flees westward in The Legend of Nigger Charley (1972). He played the role of an African-American gangster in the film Black Caesar (1973) and its subsequent sequel, Hell Up in Harlem (also 1973). Williamson also starred in the 1975 western film Boss Nigger, in which he played the title role. After this he appeared as an actor in several films, most of which are considered to be of the "blaxploitation" genre. Williamson starred alongside Peter Boyle and Eli Wallach in the movie Crazy Joe (1974). In 1974, Williamson was selected by the ABC television network as a commentator on Monday Night Football to replace Don Meredith, who had left to pursue an acting and broadcasting career at rival network NBC. Williamson was used on a few pre-season broadcasts, but was quickly declared unsuitable by ABC. He was relieved of his duties at the beginning of the regular season, becoming the first MNF personality not to endure for an entire season. He was replaced by the fellow former player (and fellow Gary, Indiana, native) Alex Karras.
