Problem: Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "Why is density important?"

Answer: "It's a physical property of matter"

Question:
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. After reading the above, is "Texas" the correct answer to the question "The proposed bill, sponsored by Rep. Charles Geveden, D-Wickliffe, would increase court filing fees in what state?"? OPTIONS:
- no
- yes

Answer:
no

Input: The CIA's senior management saw problems with the armed Predator as well, problems that Clarke and even Black and Allen were inclined to minimize. One (which also applied to reconnaissance flights) was money. A Predator cost about $3 million. If the CIA flew Predators for its own reconnaissance or covert action purposes, it might be able to borrow them from the Air Force, but it was not clear that the Air Force would bear the cost if a vehicle went down. Deputy Secretary of Defense Wolfowitz took the position that the CIA should have to pay for it; the CIA disagreed. Second, Tenet in particular questioned whether he, as Director of Central Intelligence, should operate an armed Predator." This was new ground,"he told us. Tenet ticked off key questions: What is the chain of command? Who takes the shot? Are America's leaders comfortable with the CIA doing this, going outside of normal military command and control? Charlie Allen told us that when these questions were discussed at the CIA, he and the Agency's executive director, A. B." Buzzy" Krongard, had said that either one of them would be happy to pull the trigger, but Tenet was appalled, telling them that they had no authority to do it, nor did he. Third, the Hellfire warhead carried by the Predator needed work. It had been built to hit tanks, not people. It needed to be designed to explode in a different way, and even then had to be targeted with extreme precision. In the configuration planned by the Air Force through mid-2001, the Predator's missile would not be able to hit a moving vehicle. White House officials had seen the Predator video of the "man in white." On July 11, Hadley tried to hurry along preparation of the armed system. He directed McLaughlin, Wolfowitz, and Joint Chiefs Vice Chairman Richard Myers to deploy Predators capable of being armed no later than September 1.
"Why was there concern with the "chain of command"?" is "There were concerns about going outside of normal military command and control"?

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 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).
