Question: New Legitimacy: Organized crime was soon to have a formidable adversary in its bid to control Las Vegas — corporate 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 asked — then ordered — to 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 properties — the Silver Slipper and Castaways among them — and demolished them to make way for a new kind of resort — Mirage —  which became an instant success. <sep>What did Hughes do to show his style and his dramatic side?<sep>Cloistered himself in the Desert Inn penthouse

Answer: Yes


Question: Alexander II (Russian: Aleksandr II Nikolaevich, tr. Aleksandr II Nikolaevich; IPA: [aljI'ksandr fta'roj njIka'lajIvjItc]; 29 April [O.S. 17 April] 1818 in Moscow - 13 March [O.S. 1 March] 1881 in Saint Petersburg) was the Emperor of Russia from 2 March 1855 until his assassination in 1881. He was also the King of Poland and the Grand Duke of Finland. Alexander was the most successful Russian reformer since Peter the Great. His most important achievement was the emancipation of serfs in 1861, for which he became known as Alexander the Liberator (Russian: Aleksandr Osvoboditel', tr. Aleksandr Osvoboditel; IPA: [aljI'ksandr asv@ba'djitjIlj]). The tsar was responsible for numerous other reforms including reorganizing the judicial system, setting up elected local judges, abolishing capital punishment, promoting local self-government through the zemstvo system, imposing universal military service, ending some of the privileges of the nobility, and promoting the universities. Despite these reforms, during his reign, his brutal secret police, known as the Third Section, sent thousands of dissidents into exile in Siberia. In foreign policy, Alexander sold Alaska to the United States in 1867, fearing the remote colony would fall into British hands if there was another war. He sought peace, moved away from bellicose France when Napoleon III fell in 1871, and in 1872 joined with Germany and Austria in the League of the Three Emperors that stabilized the European situation. Despite his otherwise pacifistic foreign policy, he fought a brief war with Turkey in 1877-78, pursued further expansion into Siberia and the Caucasus, and conquered Turkestan. Although disappointed by the results of the Congress of Berlin in 1878, Alexander abided by that agreement. Among his greatest domestic challenges was an uprising in Poland in 1863, to which he responded by stripping that land of its separate Constitution and incorporating it directly into Russia. Alexander was proposing additional parliamentary reforms to counter the rise of nascent revolutionary and anarchistic movements when he was assassinated in 1881. <sep>Why is Alexander II called Aleksandr Osvoboditel?<sep>For his emancipation of serfs

Answer: Yes


Question:  Late on the next Sunday afternoon Gifford had gone for a country walk which he had arranged to bring him round in time for the evening service at the little village church of Wynford standing just outside the park boundary.  His way took him by well-remembered field-paths which, although towards the end of his walk darkness had set in, he had no difficulty in tracing.  The last field he crossed brought him to a by-road joining the highway which ran through Wynford, the junction being about a quarter of a mile from the church.  As he neared the stile which admitted to the road he saw, on the other side of the hedge and showing just above it, the head of a man.  At the sound of his footsteps the man quickly turned, and, as for a moment the fitful moonlight caught his face, Gifford was sure he recognized Gervase Henshaw.  But he took no notice and kept on his way to the stile, which he crossed and gained the road.  As he did so he glanced back.  A horse and trap was waiting there with Henshaw in it.  He was now bending down, probably with the object of concealing his identity, and had moved on a few paces farther down the road. <sep>What was Gervase doing in the field?<sep>He was covertly setting a trap

Answer:
Yes
