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.

Question: How old was Stalin the year that the Meskhetian Turks were forced out of Meskheti? Passage:The Meskhetian Turks first arrived in Azerbaijan at the end of the nineteenth century, and more followed in 1918-1920. However, migration to Azerbaijan increased dramatically after World War II when the Soviet Union was preparing to launch a pressure campaign against Turkey. Vyacheslav Molotov, then Minister of Foreign Affairs, demanded to the surrender of three Anatolian provinces (Kars, Ardahan and Artvin); thus, war against Turkey seemed possible, and Joseph Stalin wanted to clear the strategic Turkish population situated in Meskheti, located near the Turkish-Georgian border which were likely to be hostile to Soviet intentions. Thus, in 1944, the Meskhetian Turks were forcefully deported from the Meskheti region in Georgia and accused of smuggling, banditry and espionage in collaboration with their kin across the Turkish border. Nationalistic policies at the time encouraged the slogan: "Georgia for Georgians" and that the Meskhetian Turks should be sent to Turkey "where they belong". Joseph Stalin deported the Meskhetian Turks to Central Asia (especially to Uzbekistan), thousands dying en route in cattle-trucks, and were not permitted by the Georgian government of Zviad Gamsakhurdia to return to their homeland.

Question: How many years did it take to develop the Sierra turbo? Passage:The second year of Group A in Australia saw the domination of the JPS Team BMW team fade with several other teams pushing forwards. Most spectacularly was the return of Nissan Motorsport Australia (now under the leadership of former Bathurst winner Fred Gibson) with the newly homologated Nissan Skyline DR30 RS turbo. Led by long time Nissan lead driver George Fury they were the main rival for another new team, the John Sheppard run Volvo Dealer Team, a factory supported team which succeeded the Mark Petch Motorsport Volvo team of 1985. The Touring Car Championship became a two horse race between Volvo's Robbie Francevic and Fury. Fury was never able to haul in Francevic's early points lead and Francevic was crowned champion. Francevic was fired from the Volvo Dealer Team by Sheppard the day after the Castrol 500 at Sandown after refusing to drive what he believed would be an un-competitive car which had only been completed at the meeting started. He then returned to the Mark Petch team as they began development of a Ford Sierra turbo. Although Francevic won the ATCC in the car, 1986 was the last time the Volvo 240T was seen in Australian touring car racing.
