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 Pausé. 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: On what date did Recitation win its maiden race at Newbury Racecourse? Passage:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.

Question: Question: How long had the Impact been a team when Drogba signed with them? Passage:In July 2004, Drogba moved to Premier League club Chelsea for a club record £24 million fee, making him the most expensive Ivorian player in history. In his debut season he helped the club win their first league title in 50 years, and a year later he won another Premier League title. His displays saw him named in the FIFA World XI for 2007. In March 2012, he became the first African player to score 100 Premier League goals. Just two months later, he scored in Chelsea's 2012 FA Cup Final win over Liverpool to become the first (and , the only) player to score in four separate FA Cup finals. He also played in the 2012 UEFA Champions League Final, in which he scored an 88th-minute equaliser and the winning penalty in the deciding shoot-out against Bayern Munich. After spending 6 months with Shanghai Shenhua in China, and one and a half seasons with Turkish club Galatasaray where he scored the winning goal in the final of the 2013 Turkish Super Cup, Drogba returned to Chelsea in July 2014. With a career record of scoring 10 goals in 10 finals winning 10 trophies at club level, Drogba has been referred to as the "ultimate big game player." He joined Canadian club Montreal Impact in 2015 as a Designated Player and played 41 matches over two seasons, scoring 23 goals. Drogba became a player–owner for Phoenix Rising of the United Soccer League in 2017, and retired a year later at the age of 40.
