The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exceptionthe presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced societythe ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d.

Problem: The Washington Supreme Court is asking the Legislature to approve a $90 surcharge on a court filing fee to help provide legal help for the poor in civil cases, Chief Justice Gerry Alexander said Wednesday. "Some might say, why should we support this when we face tough financial times?" Alexander asked in his State of the Judiciary address to a joint session of the Legislature. "It seems to me in America, where we rejoice in the fact that we are a nation devoted to the rule of law, we should not ration access to justice." The recommendation comes from the court's Task Force on Civil Equal Justice Funding, created in 2001 to look for ways to cope with the sparse amount of money available for such cases. As the task force was studying the issue, $900,000 was cut from state support for civil equal justice services. That prompted the state's two main legal services providers - Columbia Legal Services and Northwest Justice Project - to cut their staffs, Alexander said. The change would increase the cost of filing a lawsuit in Superior Court to $200. The total fee would be split, with 54 percent going to counties and 46 percent going to the state for a newly created equal justice account. Alexander also requested money for five additional Superior Court judgeships and one additional District Court judgeships, arguing that increased caseloads require more judges. Two of the Superior Court judges and the District Court judge would be in Clark County, with one Superior Court judge added in the joint district that serves Benton and Franklin counties and one each in Kittitas and Kitsap counties.

Question: "What change would increase the cost of filing a lawsuit in Superior Court?"

Romeu started his career at Barcelona's city rivals Espanyol before joining the Camp Nou academy in 2004. The midfielder, who can also play in central defence, made his debut for Barcelona in last season's Spanish Supercup match with Seville and got his first taste of league action against Deportivo in May 2010. He has played 90 minutes in both of Spain's games at the World Under-20 Championships, when they beat Costa Rica and Ecuador.

Input: Take a look at this train in Figure 1.11. It looks very futuristic. What do you notice about it? Did you notice that the train has no wheels? How can a train have no wheels? It doesn't need wheels. It actually floats, or levitates, just above the track. Magnets enable the train to do this. This is not a normal train. This is a maglev train. The word maglev stands for magnetic levitation. Because it has no wheels, there is no friction. Some magnets hold the train up. Other magnets are used to move the train forward. This train can go very fast. It can reach speeds up to 480 kilometers (300 miles) per hour! Magnets are pretty cool. What exactly is a magnet? How is it able to exert such force?

Does the response "The train is held up by magnets and the magnets also help to move the train forward" correctly answer the question "What holds the train up and moves it forward?"?

- no
