[EX Q]:  Bin Laden and his aides did not need a very large sum to finance their planned attack on America. The 9/11 plotters eventually spent somewhere between $400,000 and $500,000 to plan and conduct their attack. Consistent with the importance of the project, al Qaeda funded the plotters. KSM provided his operatives with nearly all the money they needed to travel to the United States, train, and live. The plotters' tradecraft was not especially sophisticated, but it was good enough. They moved, stored, and spent their money in ordinary ways, easily defeating the detection mechanisms in place at the time. The origin of the funds remains unknown, although we have a general idea of how al Qaeda financed itself during the period leading up to 9/11. General Financing As we explained in chapter 2,  Bin Laden did not fund al Qaeda through a personal fortune and a network of businesses in Sudan. Instead, al Qaeda relied primarily on a fund-raising network developed over time. The CIA now estimates that it cost al Qaeda about $30 million per year to sustain its activities before 9/11 and that this money was raised almost entirely through donations. For many years, the United States thought  Bin Laden financed al Qaeda's expenses through a vast personal inheritance.  Bin Laden purportedly inherited approximately $300 million when his father died, and was rumored to have had access to these funds to wage jihad while in Sudan and Afghanistan and to secure his leadership position in al Qaeda. In early 2000, the U.S. government discovered a different reality: roughly from 1970 through 1994,  Bin Laden received about $1 million per year-a significant sum, to be sure, but not a $300 million fortune that could be used to fund jihad. Then, as part of a Saudi government crackdown early in the 1990s, the  Bin Laden family was forced to find a buyer for Usama's share of the family company in 1994. The Saudi government subsequently froze the proceeds of the sale. This action had the effect of divesting  Bin Laden of what otherwise might indeed have been a large fortune. Nor were  Bin Laden's assets in Sudan a source of money for al Qaeda. When  Bin Laden lived in Sudan from 1991 to 1996, he owned a number of businesses and other assets. <sep>What source of money did bin Laden hold in Sudan?<sep>A family company
[EX A]: No

[EX Q]: 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 Howard Hughes purchase during his Vegas buying spree?<sep>Six casinos, an airport, an airline, and a large tract of land
[EX A]: Yes

[EX Q]: The Albanians first appear in the historical record in Byzantine sources of the late 11th century. At this point, they were already fully Christianized. Islam later emerged as the majority religion during the centuries of Ottoman rule, though a significant Christian minority remained. After independence (1912) from the Ottoman Empire, the Albanian republican, monarchic and later Communist regimes followed a systematic policy of separating religion from official functions and cultural life. Albania never had an official state religion either as a republic or as a kingdom. In the 20th century, the clergy of all faiths was weakened under the monarchy, and ultimately eradicated during the 1950s and 1960s, under the state policy of obliterating all organized religion from Albanian territories. The Communist regime that took control of Albania after World War II persecuted and suppressed religious observance and institutions and entirely banned religion to the point where Albania was officially declared to be the world's first atheist state. Religious freedom has returned to Albania since the regime's change in 1992. Albania joined the Organisation of the Islamic Conference in 1992, following the fall of the communist government, but will not be attending the 2014 conference due a dispute regarding the fact that its parliament never ratified the country's membership. Albanian Muslim populations (mainly secular and of the Sunni branch) are found throughout the country whereas Albanian Orthodox Christians as well as Bektashis are concentrated in the south and Roman Catholics are found in the north of the country. The first recorded Albanian Protestant was Said Toptani, who traveled around Europe, and in 1853 returned to Tirana and preached Protestantism. He was arrested and imprisoned by the Ottoman authorities in 1864. Mainline evangelical Protestants date back to the work of Congregational and later Methodist missionaries and the work of the British and Foreign Bible Society in the 19th century. The Evangelical Alliance, which is known as VUSh, was founded in 1892. Today VUSh has about 160 member congregations from different Protestant denominations. VUSh organizes marches in Tirana including one against blood feuds in 2010. Bibles are provided by the Interconfessional Bible Society of Albania. The first full Albanian Bible to be printed was the Filipaj translation printed in 1990. <sep>What religion were the majority of Albanians beforeIslam emerged as the majority religion?<sep>Christian
