Input: 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.

Does the response "Formal agricultural techniques like irrigation allowed them to live in permanent shelters year-round without the need to follow wildlife" correctly answer the question "What permitted the Anasazi to achieve a benchmark of advanced society?"?

When single father Thurman Williams needed help filling out papers in a custody suit recently, he didn't look to his lawyer for help. He walked to a computerized kiosk at the Lamoreaux Justice Center in Orange and started tapping the keys. As part of a legal experiment, litigants without lawyers across California are using computerized video kiosks to prepare common court filings and seek basic legal advice. The kiosk used by Williams is part of a statewide effort to cope with a flood of litigants who cannot afford or refuse to hire lawyers. Court officials statewide fear the number of self-represented litigants has reached crisis levels and threatens to clog court calendars. Like Williams, more than 6,000 Orange County litigants have initiated court actions on I-CAN! kiosks or accessed the programs on the Internet, using home computers. Similar programs are operating in Sacramento, San Diego and Ventura. A recent study of the kiosks' first 18 months of operation concluded it is too soon to tell if the system will relieve pressure on court calendars. But the report, by UC Irvine's School of Social Ecology, said users were overwhelmingly positive about the free legal assistance. "It's made life a lot easier for me," Williams said. "It's helped keep me from going to the poorhouse." The 29-year-old Orange resident was directed to a kiosk in the Lamoreaux Justice Center by court staff. After putting on headphones and following the directions of a videotaped instructor, Williams filled out a quarter-inch stack of paternity and custody documents. The exercise took 20 minutes; it would have cost him about $800 if he had relied on a lawyer, he said. "It was a lot easier than I thought." Whether they can't afford a lawyer or just want to save money, more Californians are going to court without a lawyer. "I'm just amazed at the numbers," said Commissioner Salvador Sarmiento, who hears between 40 and 90 child-support cases a day in Lamoreaux Justice Center.

Question: "Who made this remark: "It's helped keep me from going to the poorhouse.""

Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.

Question: "What happens to the size of the chest when the diaphragm muscle tightens?"

You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice.

Question: "Are temps always the same in glacier areas?"

Response: "No"
OPTIONS:
- no
- yes

A:
yes
