Question:
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. After reading the above, is "Salt deposits" the correct answer to the question "When does Las Vegas history begin and what covered most of the area?"?

Answer:
no

Question:
I've been thinking about the mindwipe, now two days away. Who said that those who forget the past are doomed to repeat it? I fear that may be true for me. Add this to the reasons I write now: to remember something, perhaps even to learn -- Emil Malaquez arrived after sundown, carrying a small package wrapped in what looked like real paper. His evening dress was formal, expensive, and slightly stained, as that of all forgetful artists should be. He was a jovial man with an easy laugh, and even uglier than Tasha had suggested. I liked him immediately. "Senor Malaquez?" "Please. Call me Emil. You must be Bernardo. Tasha's told me much about you." "All of it outrageous praise?" "All of it." "Ah, she is wonderfully perceptive." He raised an eyebrow, then guffawed. "Has she said as much about me?" "She thinks you are a genius. Do come in." "Thank you." After reading the above, is "Bernardo" the correct answer to the question "Whose evening dress was formal?"?

Answer:
no

Question:
Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection. After reading the above, is "Due to motion" the correct answer to the question "Why does the system work as a conveyor belt?"?

Answer:
no

Question:
What a time of it Dawson's Landing was having! All its life it had been asleep, but now it hardly got a chance for a nod, so swiftly did big events and crashing surprises come along in one another's wake: Friday morning, first glimpse of Real Nobility, also grand reception at Aunt Patsy Cooper's, also great robber raid; Friday evening, dramatic kicking of the heir of the chief citizen in presence of four hundred people; Saturday morning, emergence as practicing lawyer of the long-submerged Pudd'nhead Wilson; Saturday night, duel between chief citizen and titled stranger. The people took more pride in the duel than in all the other events put together, perhaps. It was a glory to their town to have such a thing happen there. In their eyes the principals had reached the summit of human honor. Everybody paid homage to their names; their praises were in all mouths. Even the duelists' subordinates came in for a handsome share of the public approbation: wherefore Pudd'nhead Wilson was suddenly become a man of consequence. When asked to run for the mayoralty Saturday night, he was risking defeat, but Sunday morning found him a made man and his success assured. After reading the above, is "Friends" the correct answer to the question "How had the principals reached the summit of human honor?"?

Answer:
no
