Question: The 1933 double eagle, a $20 gold piece with a mysterious history that involves a president, a king and a Secret Service sting operation, was auctioned Tuesday last night for a record price for a coin, $7.59 million, nearly double the previous record. The anonymous buyer, believed to be an individual collector who lives in the United States, made the winning bid in a fiercely contested nine-minute auction at Sotheby's in Manhattan. Eight bidders were joined by 500 coin collectors and dealers in an auction house audience seemingly devoid of celebrity bidders, while an additional 534 observers followed the bidding on eBay. As auction houses prepare for their fall seasons in an uncertain economy, the sale price "suggests that the marketplace for important items is enormously strong," said David Redden, a vice chairman at Sotheby's, who was the auctioneer. "This is an astonishing new record for a coin," he said. In an unprecedented move, the auction proceeds were split by the U.S. Mint and a London coin dealer, Stephen Fenton, who had won that right in court after having been arrested by Secret Service agents for trying to sell the coin in the Waldorf-Astoria Hotel in Manhattan in 1996. Henrietta Holsman Fore, the director of the U.S. Mint, who witnessed the sale, said, "The monies we receive will go toward helping to pay down the debt and to fight the war on terrorism." Fenton commented that the double eagle had been on "a long historic journey, with a very satisfying ending." He added, "I am thrilled with the price." The previous numismatic record holder was an 1804 U.S. silver dollar, which sold for $4.14 million in 1999. Sotheby's partner in the one-lot auction was Stack's Rare Coins, with which it shared the customary 15 percent commission. "I have never seen as much interest in the sale of any coin in my 30 years in the business," said Lawrence R. Stack, the company's managing director. "This is the Mona Lisa of coins," said Beth Deisher, editor of Coin World, the largest weekly coin publication in the United States, with a circulation of 85,000. "It is unique. Forbidden fruit." Collectors' Web sites have surged with speculation about the sale price, and enthusiasts even organized betting pools. <sep>Who is the managing director of Stack's Rare Coins?<sep>Fenton

Answer: No


Question: (CNN) -- Horror-meister, Stephen King calls George Pelecanos "perhaps the greatest living American crime writer." His stories are set in Pelecanos' hometown of Washington, D.C., but this is not the side of the U.S. capitol that you see portrayed on TV with white marble monuments, lawyers and lobbyists. Pelecanos is more interested in working families struggling to get by, the racial tensions in its ethnic neighborhoods and the low-lifes on the edges. His crime-writing peers call Pelecanos the "undisputed poet" of Washington's gritty side. The best-selling and award-winning author is out this week with his 17th and latest novel, "The Cut." It's the first in a new series featuring Iraq war veteran and private investigator Spero Lucas. When he's not working for a Washington defense attorney, Lucas recovers stolen property for a 40% cut. Now, a high-profile crime boss hires Lucas to find out who's been stealing from him, and it could turn out to be Lucas' biggest payday or an untimely end. While Pelecanos made his bones in the noir tradition, there's a definite "Western" feel to "The Cut." The new novel takes place in a morally gray and often violent world. It's peppered with pitch-perfect dialogue and captures the sights, sounds and taste of Washington in rich detail. In short, Pelecanos reads like the real deal. Pelecanos knows a thing or two about capturing the authenticity of urban America with an ethnically and socially diverse cast. In addition to his success as a novelist, Pelecanos is a producer and writer for HBO's New Orleans-set, "Treme." He was previously a producer and Emmy-nominated writer on the hit series "The Wire" and the miniseries "The Pacific." Read an excerpt from "The Cut" CNN recently spoke to Pelecanos about his new novel. The following is an edited transcript. CNN: Tell me more about your new character, Spero Lucas. <sep>As a private investigator, who does Spero Lucas work for in Pelecanos newest novel, "The Cut"?<sep>A Washington defense attorney

Answer: Yes


Question: The highest point of a wave is the crest. The lowest point is the trough. The vertical distance between a crest and a trough is the height of the wave. Wave height is also called amplitude. The horizontal distance between two crests is the wavelength. Both amplitude and wavelength are measures of wave size. The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be. Some of the biggest waves occur with hurricanes. A hurricane is a storm that forms over the ocean. Its winds may blow more than 150 miles per hour! The winds also travel over long distances and may last for many days. <sep>How do you calculate the height of a wave?<sep>The horizontal distance between two troughs

Answer:
No
