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: Out of the two fastest men in the 2018 Rallye Deutschland, which one started racing first? Passage:Five-time world champion Sébastien Ogier was the fastest man to finish the day other than the defending rally winner Ott Tänak, who set five out of six fastest stage times and built a 12.3-second lead over the Frenchman, while championship leader Thierry Neuville was another 15.1 seconds behind. Elfyn Evans climbed up three places in the afternoon loop and edged Jari-Matti Latvala by a second. Dani Sordo completed the day in sixth, only one-tenth of a second ahead of Esapekka Lappi, who failed to come to terms with dirt dragged onto the roads by the early starters. Craig Breen lost some time due to being caught in a heavy rain shower in the early stage in the eighth place, followed by Andreas Mikkelsen, who was struggling with his i20's handling and chose to change his driving style, in ninth, only one second behind. Teemu Suninen, driving a third Fiesta, in tenth. Lacking of power caused Mads Østberg to fail to find the pace like Finland, which made him cleared the day off the leaderboard in eleventh overall.

Question: When was the person to whom Ji was a subordinate born? Passage:Jiang Ji (died 18 May 249), courtesy name Zitong, was an official and military general of the state of Cao Wei during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty. After the end of the Eastern Han dynasty, he served in the state of Cao Wei through the reigns of the first three emperors – Cao Pi, Cao Rui and Cao Fang – and held various appointments in the military before rising to Grand Commandant, one of the top positions in the central government. During his service in Wei, he was known for being candid in giving advice to the emperor on various issues, including consolidating power, halting labour-intensive construction projects, and officials' abuses of power. In February 249, he joined the regent Sima Yi in staging a successful coup d'état against his co-regent Cao Shuang, but died from illness a few months later.
