[Q]: 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.

[Q]: Question: How large is the area of the field were Will and the person he shared it with in 2009? Passage:Although in 2008 Baseball America projected Venable as an every day starter for the Padres in 2010, some experts questioned whether he would be a long-term solution in center field for the team. Venable started the 2009 season with the Padres' Triple-A affiliate, Portland Beavers, but he was recalled by the Padres on June 3. His father, Max, served as the Beavers' hitting coach in 2009. Following the July 5 trade of Scott Hairston to the Oakland Athletics, Venable shared right field with Kyle Blanks. On July 12 against the San Francisco Giants, he had his first home run of the season in his first career four-hit game. Between July 30 and August 5, he homered in five of seven games. In an August 23 game against the St. Louis Cardinals, he was involved in a bench-clearing incident when Albert Pujols thought he threw an elbow while being tagged out. In 2009, he posted 12 home runs and tallied 38 runs batted in (RBI), while defensively 493.2 of his 643 innings were spent in right field and only 117 in center field.

[Q]: Question: How many rulers ruled during the Eighteenth Dynasty? Passage:Azurite is unstable in air, however it was used as a blue pigment in antiquity. Azurite is naturally occurring in Sinai and the Eastern Desert of Egypt. It was reported by F. C. J. Spurrell (1895) in the following examples; a shell used as a pallet in a Fourth Dynasty (2613 to 2494 BCE) context in Meidum, a cloth over the face of a Fifth Dynasty (2494 to 2345 BCE) mummy also at Meidum and a number of Eighteenth Dynasty (15431292 BCE) wall paintings. Depending on the degree of fineness to which it was ground, and its basic content of copper carbonate, it gave a wide range of blues. It has been known as mountain blue or Armenian stone, in addition it was formerly known as Azurro Della Magna (from Italian). When mixed with oil it turns slightly green. When mixed with egg yolk it turns green-grey. It is also known by the names blue bice and blue verditer, though verditer usually refers to a pigment made by chemical process. Older examples of azurite pigment may show a more greenish tint due to weathering into malachite. Much azurite was mislabeled lapis lazuli, a term applied to many blue pigments. As chemical analysis of paintings from the Middle Ages improves, azurite is being recognized as a major source of the blues used by medieval painters. Lapis lazuli (the pigment ultramarine) was chiefly supplied from Afghanistan during the Middle Ages, whereas azurite was a common mineral in Europe at the time. Sizable deposits were found near Lyons, France. It was mined since the 12th century in Saxony, in the silver mines located there.
