Question: How many season did the HBO show that forced Dean Winters to leave Law & Order last? Passage:For the lead roles, Christopher Meloni was cast as Detective Elliot Stabler and Mariska Hargitay was cast as Detective Olivia Benson after they auditioned together. Hargitay, who had to move from Los Angeles to New York when she got the role, said she was able to do this on short notice because she was already planning on moving to New York to pursue a Broadway career. The squad commander role was filled by Dann Florek, who had portrayed Captain Don Cragen for the first three seasons on the original Law & Order and later reprised his role in . He joined the cast on the condition that he not be asked to audition. Richard Belzer was cast as Detective John Munch, continuing his role from the series . In Belzer's words, he was cast because "Dick Wolf and Tom Fontana got drunk at a party". Halfway through the season, Richard Belzer reprised his role of Munch in , which briefly shows his character out on a case in his SVU context in New York. At Belzer's insistence, his character was partnered with Brian Cassidy, who was portrayed by Dean Winters. However, Winters' contractual obligation to the HBO series Oz forced him to leave halfway through the season. Michelle Hurd, who portrayed Detective Monique Jeffries, filled Winters' void for the remainder of the season, and was at that point added to the main credits.

Question: Which location in California where the LST-1159 stopped at has a higher land elevation? Passage:Initially attached to Amphibious Forces, Atlantic Fleet, LST-1159 conducted shakedown in Guantanamo Bay and the Caribbean before commencing local operations out of Norfolk and Little Creek, Virginia. She departed Norfolk on 24 February 1954 for duty with Amphibious Forces, Pacific Fleet, and, after a transit of the Panama Canal, reached the west coast on 20 March. The tank landing ship operated out of her new home port, San Diego, until 20 September, including calls at San Francisco, San Pedro, California, and Esquimalt, British Columbia. LST-1159 stopped briefly at Pearl Harbor before proceeding on toward Japan. While on the voyage across the Pacific, the ship was diverted to join Task Force (TF) 98 in Southeast Asian waters and arrived at Henriette Pass, near the port of Haiphong, French Indochina on 29 October.

Question: What year did the person who was an earlier French advocate of infinitesimal calculus die? Passage:Varignon was a friend of Newton, Leibniz, and the Bernoulli family. Varignon's principal contributions were to graphic statics and mechanics. Except for l'Hopital, Varignon was the earliest and strongest French advocate of infinitesimal calculus, and exposed the errors in Michel Rolle's critique thereof. He recognized the importance of a test for the convergence of series, but analytical difficulties prevented his success. Nevertheless, he simplified the proofs of many propositions in mechanics, adapted Leibniz's calculus to the inertial mechanics of Newton's Principia, and treated mechanics in terms of the composition of forces in Projet d'une nouvelle mecanique in 1687. Among Varignon's other works was a 1699 publication concerning the application of differential calculus to fluid flow and to water clocks. In 1690 he created a mechanical explanation of gravitation. In 1702 he applied calculus to spring-driven clocks. In 1704, he invented the U-tube manometer, a device capable of measuring rarefaction in gases.
