Dam Good Luck: From the beginning, Las Vegas was built to serve travelers. The railroad needed a way station, and Las Vegas was the place. Growth continued for ten years, and by 1915 the town had telephones, round-the-clock electricity, and a growing populationmany of whom worked in the railroad repair shop. But such heady progress would soon come to a halt. The growing competition in rail transport resulted in Union Pacific buying the Los AngelesSalt Lake line. Union Pacific then consolidated its operations, eliminating the Las Vegas repair facility. Additionally, Las Vegas had been made a part of Nevada's new Clark County in 1909, a year when the legislature also outlawed gambling. These unfortunate circumstances threatened to relegate Las Vegas to the status of a small desert community that could no longer support its 3000 residents. But the southwest's growing need for water, combined with Las Vegas's fortuitous proximity to the Colorado River, would give Las Vegas a second chance to achieve prosperity. Construction on Hoover Dam (originally Boulder Dam, subsequently renamed for the president who authorized the project) began in 1931 in a canyon 45 miles (72 km) southeast of Las Vegas. Providing an influx of $165 million to the southwestern economy, Hoover Dam played a major role in preventing Las Vegas from drying up, both financially and literally. Not only did it create jobs, but it also created Lake Mead, the massive reservoir that today provides water to all of southern Nevada. More Government Help: The construction of Hoover Dam did not single-handedly save Las Vegas, however. The state legislature helped as well, by legalizing gambling in 1931 and thus solidifying the future of the town, though legislators and residents could never have known this at the time. The hordes of people who attended Hoover Dam's 1935 dedication set the city's now-formidable public relations machine into action. They went to work on what has become one of the lengthiest citywide tourism campaigns ever attempted. It didn't take long for the city to establish itself as a wild-West town with an "anything goes" attitude. Vices outlawed or heavily controlled elsewhere were legal here, available any hour of any day (or night). <sep>What was the answer to the southwest's need for water?<sep>The Hoover Dam construction
Yes

Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but Bin Laden considered the basic idea feasible. Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM, Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets. Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings, Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh"). <sep>Besides Bin Laden, KSM, and Atef, who else was involved in discussing the initial selection of targets?<sep>Azzam
No

Halting just outside the village, Harry formed his men with a front across the whole road, and directed the lines to advance, twenty yards apart. Then, placing himself at their head, he gave the word, and charged down the street upon the Roundheads. The latter, occupied by their attack upon the houses, were unconscious of the presence of their foe until he was close upon them, and were taken utterly by surprise. The force of the charge was irresistible, and the Roundheads, dispersed and on foot, were cut down in all directions. Groups of twos and threes stood together and attempted resistance, but the main body thought only of regaining their horses. In three minutes after the Royalists entered the village the surviving Roundheads were in full flight, hotly pursued by the victorious Cavaliers. These, being for the most part better mounted, overtook and slew many of the Roundheads, and not more than half the force which had set out returned to their quarters at Didcot. The pursuit continued to within half a mile of that place, and then Harry, knowing that there was a force of Roundhead infantry there, drew off from the pursuit, and returned to Chalcombe. He found that more than half of Sir Ralph Willoughy's men had been killed, many having been cut down before they could betake themselves to their arms, those quartered in the inn, and at two or three of the larger houses, having alone maintained a successful resistance until the arrival of succor. <sep>What village did Sir Ralph Willoughy's forces defend?<sep>Village
No
