Input: Consider Input: 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.

Input: Consider Input: Question: What universities did first university educated Estonians attend? Passage:Although Estonian national consciousness spread in the course of the 19th century during the Estonian national awakening, some degree of ethnic awareness preceded this development. By the 18th century the self-denomination spread among Estonians along with the older . Anton thor Helle's translation of the Bible into Estonian appeared in 1739, and the number of books and brochures published in Estonian increased from 18 in the 1750s to 54 in the 1790s. By the end of the century more than a half of adult peasants could read. The first university-educated intellectuals identifying themselves as Estonians, including Friedrich Robert Faehlmann (17981850), Kristjan Jaak Peterson (18011822) and Friedrich Reinhold Kreutzwald (18031882), appeared in the 1820s. The ruling elites had remained predominantly German in language and culture since the conquest of the early 13th century. Garlieb Merkel (17691850), a Baltic-German Estophile, became the first author to treat the Estonians as a nationality equal to others; he became a source of inspiration for the Estonian national movement, modelled on Baltic German cultural world before the middle of the 19th century. However, in the middle of the century, the Estonians became more ambitious and started leaning toward the Finns as a successful model of national movement and, to some extent, toward the neighbouring Latvian national movement. By the end of 1860 the Estonians became unwilling to reconcile with German cultural and political hegemony. Before the attempts at Russification in the 1880s, their view of Imperial Russia remained positive.
