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
Yes

In remarks during a ribbon-cutting ceremony here on Wednesday, Gov. George E. Pataki said he expected the facility to generate thousands more jobs in the Hudson Valley area for contractors and suppliers catering to the factory. He praised IBM for being "a critical partner in our economic development efforts" in New York state. In a brief speech, Samuel J. Palmisano, IBM's chief executive, emphasized that it was important to make long-term investments despite the current slump in the technology business. "To play to win in technology, you innovate and you lead," he said. But manufacturing technology products is a costly and cyclical business. In June, IBM announced that it was taking a charge of more than $2 billion against earnings. The largest single reasons for the charge were the cost of getting out of the business of manufacturing hard disks for storage, which it sold to Hitachi, and closing down some of its older semiconductor operations. But Kelly said the demand for advanced chips, like those produced at IBM's facility in Burlington, Vt., is strong. "I need more capacity in that end of the market," he said, "and this is factory is critical to meeting that growing demand." If IBM has miscalculated the demand, it will suffer badly as both the high operating costs and depreciation on the huge capital investment for the East Fishkill factory drag down earnings. But industry analysts said the plant should be insulated from a falloff in one or a few segments of the semiconductor market. <sep>Who asked for more capacity in that end of the market?<sep>Samuel J. Palmisano
No

Paris, France (CNN) -- Hundreds of French workers, angry about proposed layoffs at a Caterpillar factory, were holding executives of the company hostage Tuesday, a spokesman for the workers said. Caterpillar's French staff say they are angry about a lack of negotiations over layoffs. It is at least the third time this month that French workers threatened with cutbacks have blockaded managers in their offices to demand negotiations. Executives were released unharmed in both previous situations. The latest incident started Tuesday morning at the office of the construction equipment company in the southeastern city of Grenoble. The workers were angry that Caterpillar had proposed cutting more than 700 jobs and would not negotiate, said Nicolas Benoit, a spokesman for the workers' union. They did not want to harm the Caterpillar executives, Benoit told CNN. One hostage was released Tuesday evening leaving workers with four captives inside the Caterpillar building. The released man was a human resources director identified only as Mr. Petit, because he has heart problems, union representative Bernard Patrick told CNN. Petit had a heart attack a few weeks ago, Patrick said. The four others still being held are Nicolas Polutnik, the head of operations; two other executives; and Petit's personal assistant, he said. About 500 employees were also outside the building protesting. <sep>What health issues did the released hostage Mr. Petit have?<sep>Heat attack

Yes
