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: Did Panas' uncle serve longer in Asiago or in Enego? Passage:Her artisan parents lost their jobs due to the industrialization in the region and so were forced to emigrate to the United States of America in 1902. Panas was left in the care of her paternal priest uncle Angelo who was a chaplain in Asiago and later the archpriest for Enego and who was living with his nurse sister Maria. Her schooling began under the Canossians in Feltre and later continued in Vicenza and on 5 August 1906 she made her First Communion. Panas remained in her uncle's care (receiving her initial education and religious formation from him) until her parents returned in 1910. Her parents returned with two new children Maximina and Rosa who had been born in the United States. In 1910 she moved to the Saint Alvise college in Venice and also attended the Nicolò Tommaseo Institute there before she graduated in 1913. It was following her graduation that she began teaching in the Conetta neighborhood of Cona close to Venice and it was there in 1914 that she met Father Luigi Fritz who would begin serving as her confidante and spiritual director until the end of their lives (which occurred within weeks of each other). It was also around this stage that Panas began keeping a journal and made the resolution that she would never write unless it was about or for Jesus Christ.
