Oscar-winning actress Joan Fontaine died Sunday, her longtime friend Noel Beutel said Monday. She was 96. Fontaine died "very peacefully" in her sleep of natural causes, Beutel said. She was in her Carmel, California, home. She is survived by her older sister, actress Olivia de Havilland -- with whom she had not spoken for decades. Fontaine was born Joan de Beauvoir de Havilland in 1916 in Tokyo, Japan, where her British father was a patent lawyer and teacher. She and her sister moved to Saratoga, California, with their mother in 1919 when her parents separated. Fontaine was a teenager when she began her acting career as Joan Burfield in the 1935 film "No More Ladies." She later adopted the stage name Fontaine -- the name of her mother's second husband. She wrote in her 1978 autobiography, "No Bed of Roses," that her mother, who was an actress, began encouraging the rivalry with her older sister at an early age. The feud extended to their careers when both sisters were nominated for best actress Oscars in 1942. Fontaine, who was nominated for Alfred Hitchcock's "Suspicion," beat her sister Olivia de Havilland, who was nominated for "Hold Back the Dawn." De Havilland won the first of her two Oscars in 1947 when she was given the best actress award for "To Each His Own." De Havilland and Fontaine remain the only sisters who have best-actress Academy Awards. The long-standing feud with de Havilland was at such a peak during one Oscar winners' reunion in 1979 that they had to be seated on opposite ends of the stage. "I was shocked and saddened to learn of the passing of my sister, Joan Fontaine ... and I appreciate the many kind expressions of sympathy that we have received," a statement released by Olivia de Havilland to CNN said. <sep>How many years did it take for her to get the Oscar after she was nominated for the first time?<sep>None
Yes

A flood occurs when a river overflows its banks. This might happen because of heavy rains. Floodplains In very flat regions, flood water may spread out on the surface of the land. It then slows down and drops its sediment. If a river floods often, a floodplain develops. A floodplain is an area where a thick layer of rich soil is left behind as the floodwater recedes. Thats why floodplains are usually good places for growing plants. They are very flat areas and they have very rich soils. The Nile River valley is a great example of a floodplain. Each year, the Nile River rises over its banks. This floodwater carries a lot of sediment. This sediment has been eroded off areas of land from upstream. This sediment is dropped as the water slows down after spreading across the land. What is left behind is a very rich soil. Thats why crops can be raised in the middle of a sandy desert. Natural Levees A flooding river often forms natural levees along its banks. A levee is a raised strip of sediments deposited close to the waters edge. <sep>What makes the floodplains good for growing plants?<sep>Very rich soil
Yes

On the previous evening,--March 12th,--the monotony of the camp had been unexpectedly disturbed by the arrival, from the direction of Salt Lake City, of a horseman completely exhausted by fatigue and cold, who proved to be no other than Mr. Kane, whose mission to the Mormons by way of California was at that time totally unknown to the army. The next morning he introduced himself to the Governor, was received as his guest, and remained in conference with him throughout the day. What was the character of their communication is unknown, except by inference from its results. When presented to Judge Eckels, on the following day, Mr. Kane exhibited to him the letters he bore from the President, and other letters, also, from Brigham Young, accrediting him as a negotiator in the existing difficulties. To General Johnston he showed nothing; nor did the Governor, to the knowledge of the camp, acquaint either that officer or any other person with the purport of his business. It was evident to everybody, however, that the Mormon leaders, conscious of their inability to resist the force by which they would be assailed so soon as the snow should melt upon the mountains, were engaged in an effort, of which Mr. Kane was the agent, to secure through the Governor, if possible, indemnity for their past offences, in consideration of acknowledgment of his authority. <sep>How many people was Mr. Kane involved with in his meetings?<sep>2
No
