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 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.

Input: Consider Input: Question: Which neighbouring village to Homberg had the most residents? Passage:The mediaeval historical development that Homberg experienced closely matches that experienced by neighbouring villages such as Kirrweiler, Deimberg, Buborn, Langweiler and Hausweiler. Like these places, Homberg belonged until 1140 to the Nahegau, and then thereafter until 1263 to the Waldgraviate, which itself had arisen from the Nahegau. As far as is now known, Homberg had its first documentary mention in 1319. In the document in question, an arbitrator confirmed that Waldgrave Friedrich of Kyrburg had to forgo all his claims to rights to Hoenberg and a series of other places in the “Gericht auf der Höhe” (“Court on the Heights”). The Gericht auf der Höhe was said to be a constituent district of the “Hochgericht auf der Heide” (“High Court on the Heath”), which comprised, roughly, lands in a triangle bounded by the Nahe, the Glan and the Steinalp (another river). The 1319 document dealt with a dispute between the two Waldgravial sidelines of Kyrburg and Dhaun-Grumbach. About 1344, in his own documents, the name “Friedrich von Hoenberg” appeared. He was obviously a nobleman who came from Homberg, but nothing else about him has come to light. The villages under the Gericht auf der Höhe, among which was Homberg, were pledged first, in 1363, by Johann von Dhaun to Sponheim-Starkenburg and then in 1443 by Waldgrave and Rhinegrave Friedrich to the last of the Counts of Veldenz, namely Friedrich III, whose daughter Anna married King Ruprecht's son Count Palatine Stephan. The document whereby this arrangement was laid out referred to the village's inhabitants as the “poor people of Grumbach”. By uniting his own Palatine holdings with the now otherwise heirless County of Veldenz – his wife had inherited the county upon her father Friedrich III's death in 1444, but not his comital title – and by redeeming the hitherto pledged County of Zweibrücken, Stephan founded a new County Palatine, as whose comital residence he chose the town of Zweibrücken: the County Palatine – later Duchy – of Palatinate-Zweibrücken. Thus, Homberg, and the other villages, too, lay within this duchy, but they were all returned to the Waldgraviate in 1477 when the pledge was redeemed.
