Question: New Legitimacy: Organized crime was soon to have a formidable adversary in its bid to control Las Vegascorporate cash. Though Las Vegas had developed a powerful local economy, few major outside investments were made in the city, due primarily to mob infiltration and its inherent ties to illegal activities. That would change dramatically with the 1966 arrival of billionaire Howard Hughes. A legitimate businessman, Hughes was nonetheless eccentric and dramatic, a style suited to the Las Vegas ethos. True to the myth, the reclusive Hughes immediately cloistered himself in the Desert Inn's penthouse. Several weeks later he was askedthen orderedto vacate the room to make room for high rollers, whereupon he promptly bought the property and fired the management. Thus began Hughes' legendary three-year, $300-million Las Vegas buying spree. When it was over, Hughes owned six casinos, an airport, and an airline, along with numerous plots of land stretching from the Strip to the mountains. Hughes' actions would have beneficial repercussions, both immediate and lasting. Because of the new legitimacy Las Vegas acquired from Hughes' investments, established companies such as Hilton Hotels bought into the gaming business, and their influence helped draw a line in the desert sand between legitimate operations and mob casinos, where illegal skimming of profits was rampant. That, combined with the formation of the Nevada Gaming Control Board, would signal the beginning of the end for heavy mob influence in the city. Las Vegas with a Vision As corporations moved in and the mob was slowly pushed out, a new Las Vegas emerged. The legitimization of gambling led to its increased legalization across the US. What was once a sure thing became much more competitive. Casino operators had to reassess the nature of their business. The first to really do so was Steve Wynn, a Las Vegas resident and owner of the Golden Nugget. In the mid-1980s, Wynn began plans to reinvigorate Las Vegas with a new resort. He bought several Strip propertiesthe Silver Slipper and Castaways among themand demolished them to make way for a new kind of resortMirage which became an instant success. <sep>What did Hughes do to show his style and his dramatic side?<sep>He purchased all of his properties with cash

Answer: No

Question: On to the Twentieth Century: The British extended their control over the peninsula by putting together the whole panoply of colonial administrationcivil service, public works, judiciary force, police force, post office, education, and land regulationwith teams of British administrators, teachers, engineers, and doctors to go with it. At the same time, the tin industry, dominated by Chinese using labor-intensive methods in the 19th century, passed increasingly into Western hands, who employed the modern technology of gravel pumps and mining dredges. Petroleum had been found in northern Borneo, at Miri, and in Brunei, and the Anglo-Dutch Shell company used Singapore as its regional depot for its oil supplies and exports. But the major breakthrough for the Malay economy was the triumph of rubber, when Singapore's new garden director, Henry Ridle ("Rubber Ridley" to his friends, "Mad Ridley" to all doubting Thomases) had developed new planting and tapping methods and painstakingly spread his faith in rubber around the peninsula. World demand increased with the growth of the motor-car and electrical industries, and sky-rocketed during World War I. By 1920, Malaya was producing 53 percent of the world's rubber, which had overtaken tin as its main source of income. The Malay ruling class again took a back seat. Together with effective control of the rubber and tin industries, the British now firmly held the reins of government. The sultans were left in charge of local and religious affairs, content with their prestige, prosperity, and security. The census of 1931 served as an alarm signal for the Malay national consciousness. Bolstered by a new influx of immigrants to meet the rubber and tin booms of the 1920s, non-Malays now slightly outnumbered the indigenous population. The Great Depression of 1929 stepped up ethnic competition in the shrinking job market, and nationalism developed to safeguard Malay interests against the Chinese and Indians rather than the British imperial authority. Though hampered by the peninsula's division into the States and the Straits Settlements, relatively conservative Muslim intellectuals and community leaders came together at the Pan-Malayan Malay Congress in Kuala Lumpur in 1939. In Singapore the following year, they were joined by representatives from Sarawak and Brunei. Teachers and journalists urged the revival of the common Malay-Indonesian consciousness, split by the Anglo-Dutch dismemberment of the region in the 19th century. This spirit became a factor in the gathering clouds of war. <sep>What caused the Malay ruling class to take a back seat?<sep>Auto and electrical industry demand for rubber, which dramatically increased during World War I

Answer: Yes

Question: Although Bin Laden, Atef, and KSM initially contemplated using established al Qaeda members to execute the planes operation, the late 1999 arrival in Kandahar of four aspiring jihadists from Germany suddenly presented a more attractive alternative. The Hamburg group shared the anti-U.S. fervor of the other candidates for the operation, but added the enormous advantages of fluency in English and familiarity with life in the West, based on years that each member of the group had spent living in Germany. Not surprisingly, Mohamed Atta, Ramzi Binalshibh, Marwan al Shehhi, and Ziad Jarrah would all become key players in the 9/11 conspiracy. Mohamed Atta was born on September 1, 1968, in Kafr el Sheikh, Egypt, to a middle-class family headed by his father, an attorney. After graduating from Cairo University with a degree in architectural engineering in 1990, Atta worked as an urban planner in Cairo for a couple of years. In the fall of 1991, he asked a German family he had met in Cairo to help him continue his education in Germany. They suggested he come to Hamburg and invited him to live with them there, at least initially. After completing a course in German, Atta traveled to Germany for the first time in July 1992. He resided briefly in Stuttgart and then, in the fall of 1992, moved to Hamburg to live with his host family. After enrolling at the University of Hamburg, he promptly transferred into the city engineering and planning course at the Technical University of Hamburg-Harburg, where he would remain registered as a student until the fall of 1999. He appears to have applied himself fairly seriously to his studies (at least in comparison to his jihadist friends) and actually received his degree shortly before traveling to Afghanistan. In school, Atta came across as very intelligent and reasonably pleasant, with an excellent command of the German language. When Atta arrived in Germany, he appeared religious, but not fanatically so. This would change, especially as his tendency to assert leadership became increasingly pronounced. According to Binalshibh, as early as 1995 Atta sought to organize a Muslim student association in Hamburg. In the fall of 1997, he joined a working group at the Quds mosque in Hamburg, a group designed to bridge the gap between Muslims and Christians. Atta proved a poor bridge, however, because of his abrasive and increasingly dogmatic personality. But among those who shared his beliefs, Atta stood out as a decisionmaker. <sep>Who were the four aspiring jihadists from Germany who arrived in Kandaharin late 1999?<sep>Ziad Jarrah

Answer:
Yes
