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.

(CNN) -- Deposed Honduran President Jose Manuel Zelaya will not be reinstated as head of state, an overwhelming majority of the Honduran congress voted Wednesday. In an hours-long process, 111 lawmakers voted in favor of a motion not to return Zelaya to office. A majority of 65 votes in the 128-member body was required to reject his reinstatement. Zelaya was removed from office in a military-led coup on June 28 and replaced by congressional leader Roberto Micheletti. On Wednesday, lawmakers voted one by one and addressed the chamber as they cast their vote, making for a slow process. The vote was a key part of a U.S.-brokered pact that representatives for Zelaya and Micheletti signed October 29, giving Congress the power to decide Zelaya's fate. The United States expressed disappointment Thursday over the latest rebuff to its diplomatic efforts to end the political crisis in Honduras. U.S. Assistant Secretary of State for Western Hemisphere Affairs Arturo Valenzuela continued to call on the Honduran government to allow Zelaya's return and to create a unity government in the interim period before the new president takes office next month. "We are disappointed by this decision since the United States had hoped the [Honduran] Congress would have approved his return," Valenzuela said in a conference call with journalists in Washington. "Our policy since June 28 has been consistently principled. It has condemned the coup d'etat and continued to accept President Zelaya as the democratically elected and legitimate leader of Honduras throughout this political crisis." The United States continues to call for Honduras to engage in national reconciliation and creation of a truth commission to investigate the crisis, in addition to the unity government. "The absence of democratic, constitutional order is the unacceptable status quo," a senior U.S. administration official said on the conference call, remaining anonymous under the ground rules of the call and because of the sensitivity of the situation. "The election is a step toward a day where Honduras will have an electorally legitimate government in place."

Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Question: "Name two benefits of Earths magnetic field."

OPTIONS:
- no
- yes

Answer: "It helps with gravity and condensation"

Response: no

Captured Moments by Will Shetterly I remember Papa's stopbox, a teal blue Tiempo Capturado that Mama brought home for his birthday. It was huge and inefficient, and she should never have spent so many pesos on a toy, but Papa would not let her return it. He used it to preserve baby tomatoes, cucumbers, and strawberries in translucent cubes that he stored in the pantry for spring-time meals in the middle of winter. Mama kept her mink jacket, a family hand-me-down, safe from time in a stopbox, and lent the capturador to my uncle for his stamp collection. Sometimes they would let us little ones to seal a treasured toy or a last piece of birthday cake until we begged them for its release, usually a few hours after enclosing it. When my father died, a year after my mother, my sisters and I cleaned out their apartment. We found our baby shoes protected in stopboxes. I took mine home, where they sat above my computer while I worked on my first play. One night when I did not believe love had ever existed for anyone, I used my own capturador, a sleek titanium Sanyo Tardar Ahora, to undo the stopbox. Bringing my face close to the shoes, I breathed deeply of air that my parents had trapped while closing up that symbol of their love for me. The instant would have been improved had my baby shoes been cleaned before they were encased. But as soon as I coughed, I laughed, and I did not try to kill myself that night.
