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 Howard Hughes purchase during his Vegas buying spree?<sep>Six casinos, an airport, an airline, and a large tract of land

The Romans: Legend says Rome was founded by Romulus, sired with twin brother Remus by Mars of a Vestal Virgin and abandoned on the Palatine Hill to be suckled by a she-wolf. Historians agree with the mythmakers that the site and traditional founding date of 753 b.c. are just about right. Under Etruscan domination, Rome had been a monarchy until a revolt in 510 b.c. established a patrician republic, which lasted five centuries. In contrast to other Italian cities weakened by internal rivalries and unstable government, Rome drew strength from a solid aristocracy of consuls and senate ruling over plebeians proud of their Roman citizenship and only rarely rebellious. Recovering quickly from the Gallic invasion of 390 b.c. , the Romans took effective control of the peninsula by a military conquest reinforced by a network of roads with names that exist to this day: Via Appia, Flaminia, Aurelia. All roads did indeed lead toand fromRome. By 250 b.c. , the city's population had grown to an impressive 100,000. Roman power extended throughout the Mediterranean with a victory in the Punic Wars against Carthage (now Tunisia) and conquests in Macedonia, Asia Minor, Spain, and southern France. The rest of Italy participated only by tax contributions to the war effort and minor involvement in commerce and colonization. Resentment surfaced when former Etruscan or Greek cities such as Capua, Syracuse, and Taranto supported Hannibal's invasion in 218 b.c. Rome followed up defeat of the Carthaginians with large-scale massacres and enslavement of their Italian supporters. The Third and final Punic War ended in 149 b.c. , though national solidarity was still a long way off. Under Julius Caesar, elected in 59 b.c. <sep>How many times was there uprising in Rome?<sep>3

Ex Input:
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>What do we know about wavelength from the paragraph?<sep>It is the distance between two crests, and is a factor in wave size
