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 "1000 a.d" correctly answer the question "When did the Anasazi begin to inhabit the valley?"?

Input: A West Tennessee nonprofit organization will use a $300,000 federal grant to hire an attorney and a Spanish-speaking paralegal to help provide legal assistance to domestic violence victims. The U.S. Department of Justice two-year grant will begin Oct. 1, which is the start of domestic violence awareness month. U.S. Rep. John Tanner announced Monday that the grant was awarded to West Tennessee Legal Services of Jackson. The organization provides legal assistance and advocacy in 17 counties. "This award will offer assistance as we look for whatever ways possible to stop domestic violence and help the women, men and children who are victims of abuse," Tanner said in a news statement. The organization doesn't have a staff member who speaks Spanish and the need is increasing with growing Hispanic populations, said the organization's executive director Steven Xanthopoulos. He estimated the money will help handle at least another 180 cases next year. The group closes about 2,500 cases a year. The money was timed well because the legal group had recently lost about $120,000 in grant money due to a decrease in the poverty population in West Tennessee in Census 2000, Xanthopoulos said. "The drop in poverty is a good thing, but there is still a great need out there," he said. "So this was a very good thing." Having legal representation at divorce and child custody hearings is important in helping victims leave abusive and sometimes dangerous situations, said Margaret Cole, executive director of Wo/Men's Resource and Rape Assistance Program in Jackson. Her organization and Northwest Safeline are partners in the grant. Northwest Safeline, based in Dyersburg, is a family violence intervention project that serves Dyer, Obion, Lake and Crockett counties.

Does the response "500" correctly answer the question "How many more cases will the grant money that West Tennessee Legal Services be able to handle next year?"?

Input: Alexander the Great's accomplishments and legacy have been depicted in many cultures. Alexander has figured in both high and popular culture beginning in his own era to the present day. The Alexander Romance, in particular, has had a significant impact on portrayals of Alexander in later cultures, from Persian to medieval European to modern Greek. Alexander may already have considered himself as the "King of Asia" after his victory at Issos, a conception strengthened by his subsequent successes. The conception might have inspired the title given to Alexander in Babylonian documents, "king of the world (since "king of Asia" had no meaning in Babylonian geography). It might also be alluded in the sarcastic comments by Anaxarchus, trying to rouse Alexander after the murder of Cleitus. or in the orator Demades' comments that if Alexander were dead, "The whole world would stink of his corpse". Alexander is called "kosmokrator", ruler of the world, in the later Alexander Romance. Alexander features prominently in modern Greek folklore, more so than any other ancient figure. The colloquial form of his name in modern Greek ("O Megalexandros") is a household name, and he is the only ancient hero to appear in the Karagiozis shadow play. One well-known fable among Greek seamen involves a solitary mermaid who would grasp a ship's prow during a storm and ask the captain "Is King Alexander alive?". The correct answer is "He is alive and well and rules the world!", causing the mermaid to vanish and the sea to calm. Any other answer would cause the mermaid to turn into a raging Gorgon who would drag the ship to the bottom of the sea, all hands aboard.

Does the response "Demades' comments that if Alexander were dead, "The whole world would stink of his corpse"" correctly answer the question "What were the orator Demades' comments referring to Alexanders death?"?
