Input: Consider Input: 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 population — many 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 Angeles–Salt 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

Output: Yes


Input: Consider Input: Backers of Legal Aid services for the poor are pushing a measure that would increase court filing fees in Kentucky to raise money for the program, which faces steep funding cuts. The proposed bill, sponsored by Rep. Charles Geveden, D-Wickliffe, would double the portion of the fee that goes to Legal Aid -- in district court to $10 from $5 and in circuit court to $20 from $10. Kentucky's current fee for filing a case in district court is $50.50, and in circuit court $108. The increase still would leave Kentucky's filing fee costs below those of surrounding states and would raise about $1.3 million a year -- almost enough to replace what Legal Aid is losing from federal and other sources, said Jamie Hamon, executive director of the Access to Justice Foundation, a state poverty law resource center in Lexington. Geveden said his measure appears to be the only potential source of money for the program, which is being forced to lay off workers and close offices around the state. Geveden said he's concerned because federal funding hasn't increased in recent years, and states with increased poverty are taking a greater share of the money. ''If you don't come up with the money somewhere, legal services to people in need will diminish or go away,'' he said. Hamon said the proposed bill has attracted a number of co-sponsors, and Legal Aid backers are hoping to get it passed in the upcoming legislative session. Hamon said she knows fee increases aren't popular with lawmakers but hopes they realize the crisis Legal Aid is facing. ''A lot of poor people are not going to get served,'' she said. The measure has the endorsement of the Kentucky Bar Association. The association's board of governors voted unanimously last month to back the bill, said KBA President Stephen Catron, a Bowling Green lawyer. Legal Aid ''has been a godsend to a great number of people in this state,'' Catron said. ''We simply must find a way to provide those services to the public.'' Larry York, executive director of Appalachian Regional Defense Fund, which provides Legal Aid services in 37 Eastern Kentucky counties and is a KBA board member, said he hopes the measure is approved. ''It would really offset the current cuts,'' he said. <sep>What organization has endorses the measure to increase legal aid fees?<sep>The Kentucky Bar Association

Output: Yes


Input: Consider Input: Right after the Pentagon was hit, NEADS learned of another possible hijacked aircraft. It was an aircraft that in fact had not been hijacked at all. After the second World Trade Center crash, Boston Center managers recognized that both aircraft were transcontinental 767 jetliners that had departed Logan Airport. Remembering the "we have some planes" remark, Boston Center guessed that Delta 1989 might also be hijacked. Boston Center called NEADS at 9:41 and identified Delta 1989, a 767 jet that had left Logan Airport for Las Vegas, as a possible hijack. NEADS warned the FAA's Cleveland Center to watch Delta 1989. The Command Center and FAA headquarters watched it too. During the course of the morning, there were multiple erroneous reports of hijacked aircraft. The report of American 11 heading south was the first; Delta 1989 was the second. NEADS never lost track of Delta 1989, and even ordered fighter aircraft from Ohio and Michigan to intercept it. The flight never turned off its transponder. NEADS soon learned that the aircraft was not hijacked, and tracked Delta 1989 as it reversed course over Toledo, headed east, and landed in Cleveland. But another aircraft was heading toward Washington, an aircraft about which NORAD had heard nothing: United 93. United Airlines Flight 93 FAA Awareness. At 9:27, after having been in the air for 45 minutes, United 93 acknowledged a transmission from the Cleveland Center controller. This was the last normal contact the FAA had with the flight. Less than a minute later, the Cleveland controller and the pilots of aircraft in the vicinity heard "a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin." The controller responded, seconds later: "Somebody call Cleveland?"This was followed by a second radio transmission, with sounds of screaming. <sep>At what time did the last normal contact between United 93 and the FAA?<sep>9:45


Output: No
