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: On what date did Morsi take office? Passage:Following the Egyptian revolution of 2011 as part of the regional Arab Spring protests, Mubarak was ousted and the following year Mohamed Morsi who is backed by the Muslim Brotherhood won Egypt's first democractic elections. In 2013 Morsi was removed from power in a coup led by Abdel Fattah el-Sisi. Sisi has called for religious tolerance and has cracked down and banned the Muslim Brotherhood. He has closed thousands of mosques and has banned 'burkinis' on some beaches. A The Economist report in 2017 stated that Egyptians were turning more secular again, with supporters of sharia law dropping by more than half since 2011, people praying less than before, and gender equality now being widely accepted. The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.

Question: In what year was Columbia University founded? Passage:Columbia (; ) is the female personification of the United States. It was also a historical name used to describe the Americas and the New World. It has given rise to the names of many persons, places, objects, institutions and companies; for example: Columbia University, the District of Columbia (the national capital of the United States), and the ship Columbia Rediviva, which would give its name to the Columbia River. Images of the Statue of Liberty largely displaced personified Columbia as the female symbol of the United States by around 1920, although Lady Liberty was seen as an aspect of Columbia. The District of Columbia is named after the personification, as is the traditional patriotic hymn "Hail Columbia", which is the official vice presidential anthem of the United States Vice President.
