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.

At length, as I entered the pass, the huge rocks began to close around in all their wild, mysterious impressiveness, when suddenly, as I was gazing eagerly about me, a drove of gray hairy beings came in sight, lumbering toward me with a kind of boneless, wallowing motion like bears. I never turn back, though often so inclined, and in this particular instance, amid such surroundings, everything seemed singularly unfavorable for the calm acceptance of so grim a company. Suppressing my fears, I soon discovered that although as hairy as bears and as crooked as summit pines, the strange creatures were sufficiently erect to belong to our own species. They proved to be nothing more formidable than Mono Indians dressed in the skins of sage-rabbits. Both the men and the women begged persistently for whisky and tobacco, and seemed so accustomed to denials that I found it impossible to convince them that I had none to give. Excepting the names of these two products of civilization, they seemed to understand not a word of English; but I afterward learned that they were on their way to Yosemite Valley to feast awhile on trout and procure a load of acorns to carry back through the pass to their huts on the shore of Mono Lake.

Question: "Why was he inclined to turn back?"

OPTIONS:
- no
- yes

Answer: "Fear"

Response: no

In 1990, the U.S. Custom House in New York City was renamed after Hamilton. In 1880, his son John Church Hamilton commissioned Carl Conrads to sculpt a granite statue, now located in Central Park, New York City. One statue honoring Alexander Hamilton in Chicago was mired in controversy, at least concerning the surrounding architecture. Kate Sturges Buckingham (1858-1937), of the Buckingham Fountain family, commissioned the monument. Its impetus was that Treasury Secretary Hamilton "secured the nation's financial future and made it possible for her own family to make its fortune in grain elevators and banking. Consequently, John Angel was hired to model a figurative sculpture and the Finnish architect Eliel Saarinen was to create a "colossal architectural setting" for it. The proposed 80-foot tall columned shelter was poorly received. By Ms. Buckingham's death in 1937, the sculpture's setting. location and design were uncertain. Conspiracy allegations surfaced, and the matter became mired in litigation. After the courts ordered the construction to be completed by 1953, the trustees hired architect Samuel A. Marx. The structure was completed, had structural problems, and was eventually demolished in 1993. The statue was gilded, and is still on display. A statue, by James Earle Fraser, was dedicated on May 17, 1923, on the south terrace of the Treasury Building, in Washington.

Question: "What is the name of the family that Hamilton had helped secure the fortune of who then dedicated a statue in his name?"

OPTIONS:
- no
- yes

Answer: "The Buckingham Fountain familyKate Sturges Buckingham then dedicated a statue in his name"

Response: yes

Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .

Question: "Of all the features with Which the probes are equipped, Which is primarily for communication with alien life forms?"

OPTIONS:
- no
- yes

Answer: "Holographic message"

Response:
yes
