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.
"Was agriculture and forms early civilization available at any point in Las Vega's history?" is "No"?

Input: 863. INGREDIENTS.--The remains of a boiled calf's head, 1-1/2 pint of the liquor in which the head was boiled, 1 blade of pounded mace, 1 onion minced, a bunch of savoury herbs, salt and white pepper to taste, thickening of butter and flour, the yolks of 2 eggs, 1 tablespoonful of lemon-juice, forcemeat balls. _Mode_.--Remove all the bones from the head, and cut the meat into nice square pieces. Put 1-1/2 pint of the liquor it was boiled in into a saucepan, with mace, onion, herbs, and seasoning in the above proportion; let this simmer gently for 3/4 hour, then strain it and put in the meat. When quite hot through, thicken the gravy with a little butter rolled in flour, and, just before dishing the fricassee, put in the beaten yolks of eggs and lemon-juice; but be particular, after these two latter ingredients are added, that the sauce does not boil, or it will curdle. Garnish with forcemeat balls and curled slices of broiled bacon. To insure the sauce being smooth, it is a good plan to dish the meat first, and then to add the eggs to the gravy: when these are set, the sauce may be poured over the meat.

Does the response "No, the calf's head meat is not in the pot at the same time that Sentence is done" correctly answer the question "Is the calf's head meat still in the pot at the time that Sentence 5 is done?"?

Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.

Question: "What two types of charges build up in unbalanced items?"

OPTIONS:
- no
- yes

Answer: "Neutral"

Response: no

When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison.

Question: "What are the advantages of tall grass prairies?"

Response: "Buildings construction"

Problem: Once upon a time I had a dog named Toodles. He was black and white and had long floppy ears. He also had very short legs, but really big paws. Every Saturday we would go to the park and play Toodles' favorite game. Toodles loved playing fetch. One Saturday, Toodles ran over to the pond because he saw ducks swimming there. He ran all around the pond, barking at the ducks. The ducks ignored him, and kept swimming. Toodles wasn't having it! He jumped into the pond and started swimming toward the ducks, chasing around his new playmates. One of the ducks, braver than the others, poked Toodles with his beak - and then bit him right on one of his floppy ears! Toodles barked and ran out of the pond because the duck hurt his ear. Soaking wet, he ran toward where I was eating a sandwich on the grass and curled right up in my lap so I could make him feel better. After that, whenever he would see a duck, Toodles would run the other way.

Question: "Where was the pond"

Answer: "In the park"
