Question: Question: What year was the School of American Ballet founded? Passage:Waring's training began in 1939 in San Francisco and Oakland at the age of 17. He was exposed to numerous kinds of dancing, including ballet at the San Francisco Ballet School with Harold Christensen and his brother, the Graham technique with Gertrude Schurr, and the interpretive dance of Raoul Pause. Later, after serving in the Army in World War II, he studied in New York City at the School of American Ballet, and with Anna Halprin, Louis Horst, Antony Tudor, and Anatole Vilzak, and also took some classes with Merce Cunningham. Waring was very attracted to ballet and intrigued by its complex history and sensibility, and dance historian David Vaughan suggests that Waring's extensive knowledge of dance history played an important role in his work; Waring's dances became more balletic over time.

Question: Question: What year did the team that Bay returned from the DL against in June last win a championship? Passage:Bay got off to a slow start to the 2012 season, finishing spring training with no home runs or RBI, and his regular season, which was derailed further by a broken rib suffered while making a diving catch in the April 23 game against the San Francisco Giants. When Bay returned from the DL on June 8, 2012 against the New York Yankees, he went 0-for-3 with one strikeout. He continued to go 0-for-16 in his return from the DL through June 12, before hitting a single on June 13 against the Tampa Bay Rays. In a home game against the Cincinnati Reds on June 15, Bay left the game in the second inning after crashing into the left field wall and suffering a concussion while attempting to catch a fly ball by Jay Bruce that became an inside-the-park home run. He was subsequently placed on the DL again, and returned again on July 17 against the Washington Nationals. On September 2, Bay hit a grand slam off of Miami Marlins pitcher Mark Buehrle in the first inning of a 52 Mets win. Bay also hit a home run off of Buehrle on September 22 in a 43 Mets win. Bay finished the 2012 season with a .165 batting average, 8 home runs and 20 RBI.
