I'm taking a test and have to guess the right answer to the question after the article. Article: Joker found one of the biggest diamonds in the world in his own back yard. He sold the stone to a diamond dealer for over three hundred thousand dollars. In New York, the diamond was resold. This time for almost eight hundred thousand dollars. The true value of a diamond is never known until it has been cut. Once cut successfully, its value can increase a thousand times. It's easy to understand why the owner of the Joker diamond went to the best diamond cutter he knew, Kaplan. The cutter studied the diamond for twelve whole months. When he felt he was ready to start work, he discovered a flaw . He had to begin with his calculations all over again, or he might have made the stone useless. Six more months passed, and Kaplan finally said to the owner, "I m ready to start my work. There will be one excellent diamond that be comparable to any in the world, plus eleven small diamonds of first-class quality." Kaplan waited a few more days until be felt he was in the best physical and mental condition possible. He picked up his tools and held his breath as he made the first blow. The diamond split exactly as he promised. Question: The owner of the diamond thought that if the diamond was cut successfully it might be worth _ . Options: A: $300,000 B: $500, 000 C: $300, 000,000 D: $800, 000, 000

I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists at Harvard University and Bates College find female chimpanzees appear to treat sticks as dolls, carrying them around until they have children of their own. Young males engage in such behavior much less frequently. The new work by Sonya M. Kahlenberg and Richard W. Wrangham, described this week in the journal Current Biology, provides the first evidence of a wild nonhuman species playing with dolls, as well as the first known sex difference in a wild animal's choice of playthings. The two researchers say their work adds to a growing body of evidence that human children are probably born with their own ideas of how they want to behave, rather than simply mirroring other girls who play with dolls and boys who play with trucks. Doll play among humans could have its origins in object--carrying by earlier apes , they say, suggesting that toy selection is probably not due entirely to socialization. "In humans, there are obvious sex differences in children's toy play, and these are remarkably similar across cultures," says Kahlenberg. "While socialization by elders and peers has been the primary explanation, our work suggests that biology may also have an important role to play in activity preferences." In 14 years of data on chimpanzee behavior at the Kibale National Park in Uganda, Kahlenberg and Wrangham counted more than 100 examples of stickcarrying. Some young chimpanzees carried sticks into the nest to sleep with them and on one occasion built a separate nest for the stick. "We have seen juveniles occasionally carrying sticks for many years, and because they sometimes treated them rather like dolls, we wanted to know if in general this behavior tended to represent something like playing with dolls," says Wrangham, a Professor at Harvard. "If the doll hypothesis was right, we thought that females should carry sticks more than males do, and that the chimpanzees should stop carrying sticks when they had their first child. We have now watched enough young chimpanzees to prove both points." Question: What causes the different toy selection of chimpanzees, according to the passage? Options: A: Sex difference. B: Socialization. C: Environment. D: Cultural difference.

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The Eiffel Tower was built in 1889, in memory of the 100th birthday of the French Revolution. The Prince of Wales, later King Edward VII of England, opened the tower. Of the 700 suggestions that were handed in, Gustave Eiffel's was chosen. However, at first, it was not well accepted by all and a group of people -- including many well-known writers and painters at that time -- were fiercely against its design. Being about 300 meters in height, and 7,000 tons in weight, it was the world's tallest building until 1930. It was a great project for France. 300 workers took two years to build it. It isn't an ordinary building, since it is almost made of steel. For example, its body moves around at most 12 cm in heavy wind. Moreover, its height changes up to 15 cm according to the temperature. It was almost destroyed in 1909, but was saved because of its antenna , which is used for communication at that time. Beginning in 1910 it became part of the International Time Service. French radio and French television have also made good use of its height. The Eiffel Tower has also seen a few strange things. In 1923, a journalist rode a bicycle down from the first level of it. And in 1954, a mountain climber climbed on top of it and tried to measure its exact height. Anyway, although its birth was difficult, it is now well accepted all over the world. It has been considered as one of the symbols of Paris. Question: The French Revolution took place in _ . Options: A: 1889 B: 1923 C: 1789 D: 1930

I'm taking a test and have to guess the right answer to the question after the article. Article: Very far away from the city lived a poor farmer and his wife. In front of their house was a small dirt road. Very few cars drove on this road because it was so far from the city. On the dirt road, there was a big hole filled with water. The hole was very deep, but drivers on the road didn't know just how deep. Drivers always drove into the hole, but they never drove out. One day, a man in a new car was driving down the road. He saw the hole with the water, but he didn't think it was very deep. He drove into the hole, but he couldn't drive out. The man saw the farmer on his tractor working in the field, and he signaled to the farmer. The farmer drove over to the man in the new car. "Is there a problem?"asked the farmer. "Yes,"said the man."My car is stuck in this hole. Can you help me?" "Maybe,"said the farmer."But I'm very busy." "lf you help me, I'll pay you," said the man. "OK,"said the farmer. The farmer pulled the car out of the hole with his tractor, and the man paid him a lot of money. The man looked at the farmer and said,"You must. make a lot of money pulling cars out of this hole day and night." "Actually, no,"said the farmer. "Why not?"asked the man. "The hole is very deep, and a lot of people get stuck and ask for help. But I don't make money day and night because I don't pull cars out at night." "At night I'm busy filling the hole with water," answered the farmer. Question: What did the farmer usually do at night? Options: A: He helped pull out cars. B: He made money. C: He filled water to the hole D: He slept at home.
