Input: 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.

Does the response "An airport" correctly answer the question "What was the first property that the Mirage owner owned in Vegas?"?

Input: Brad, Texas (CNN) -- Authorities were working on plans Friday for residents who were forced to flee a wildfire in northern Texas to return home, a day after firefighters made progress battling the blaze that destroyed dozens of homes. The blaze in Palo Pinto County scorched 6,200 acres by Thursday, according to the Texas Forest Service. The fire is burning near the resort of Possum Kingdom Lake, near the town of Brad, about 100 miles west of Dallas. "We feel much better about this fire today," as the blaze is now 50% contained, said John Nichols, a spokesman for the Forest Service. He said evacuations were lifted for some residents forced to evacuate the fire, which was driven by high temperatures and dry winds. The wildfire has destroyed 40 homes and nine RVs since it began Tuesday, the Forest Service said Thursday. Firefighters were receiving support from aerial tankers and helicopters. Authorities are mapping out plans to allow residents to return to their homes, said Palo Pinto County Sheriff Ira Mercer. Authorities also are trying to open the lake for the Labor Day holiday, he said. On Wednesday, evacuations were ordered in several communities on the north side of the lake after the fire charged over a ridge and approached a dam on the lake, CNN affiliate WFAA reported. The wildfire was moving so fast that the Forest Service pulled out of its command observation post, telling journalists and onlookers to get out of the way of the fire. "My house is right through here, though it may be gone," Tom Hardeston told WFAA as he watched the fire. Nearby ranchers battled to save their herds from the encroaching fire. "I'm just moving them from pasture to pasture," Cindi McCoy told WFAA, referring to her livestock. "As one pasture burns, I'm moving them back to that one and bring(ing) them back around."

Input: When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison.

Does the response "Space for prairie dogs" correctly answer the question "Why do we clear land?"?

Input: Little is known of the earliest Stone Age inhabitants of Europe's southwestern extremity. The ancient Greeks called them the Cynetes (or Cunetes). Whatever their origins, their culture evolved under the pressure and influence of foreign forces. Among the many invading armies that settled here and contributed to nascent Portuguese culture were Phoenicians, who settled in the area around 1,000 b.c., followed by the Celts, Iberians, Greeks, and Carthaginians. But it was the Romans, who arrived late in the third century b.c., who most greatly influenced all of Iberia. They built towns, industries, roads, and bridges, developed agriculture, and bequeathed the Latin language, of which Portuguese is a direct descendant. The Romans named the southwestern province of the peninsula Lusitania, oddly enough for one of the Celtiberian tribes they defeated, and by the third century a.d. had introduced Christianity. By the beginning of the fourth century the Algarve had a bishop in place, based in Faro. But Rome had already fallen into decay, and soon hordes of northern tribesmen took over the empire. The Algarve fell to the Visigoths in the mid-fifth century. Under Moorish Rule In a.d. 711, the Moors brought powerful armies from North Africa and launched a devastating attack on the Iberian peninsula, conquering much of what would become Spain and Portugal. They imposed Islam and left an indelible influence on the countryside and the population of the Algarve. The Moorish legacy can still be seen in the form of wells and waterwheels, squat white houses, the dark complexions of the people, and in the very name given the regiontaken from Al-Gharb, which means "country of the west" (when the Moors conquered the territory, it was the most westerly in the known world). The Moors governed their Iberian kingdoms from across the border in Seville, but the Algarve had its own regional capital and huge, invulnerable fortress. The capital was Chelb (or Xelb), and it was bigger and better defended than Lisbon. Today the town, known as Silves, is a provincial outpost whose only besiegers are busloads of tourists who climb the narrow streets up to the old Moorish ramparts.

Does the response "Stone age" correctly answer the question "What was the Portuguese city of Silves was once known as?"?
