I'm taking a test and have to guess the right answer to the question after the article. Article: Once again, rumors are spreading. Judgment Day, this time, is set to happen on December 21st, 2012. The date originated from the Mayan calendar, but actually gained popularity through the hit movie, "2012". How will the world end? And how do we know the exact date? There are many theories: A meteoroid from outer space; a solar storm; a shift in the earth's poles; bla bla bla. They all supposedly pointed to the date of December 21st, 2012. Unfortunately, none of it is true. Zhu Jin, director of Beijing Planetarium, said, "For earth itself, the end will be billions of years away from now.And for us humans, there is a very small chance that we may be affected by some astronomical factors.However, we don't have the ability to foresee such events so far.So when someone tells you the world is going to end on an exact date, it must be fake." But the truth hasn't stopped people from believing. In the sci-fi movie "2012", the director imagined the end of the world based on the Mayan calendar. The film earned nearly 770 million US dollars worldwide. Ning Hong, Hebei Province, said. "The movie 2012 did get one thing right. There are arks being made in China, But they're not being built secretly inside the mountains.They are constructed here in the courtyard of a factory." In April, Liu Qiyuan quit his furniture business and devoted himself to developing these huge round balls. He doesn't believe the end is near, but he wants to be prepared just in case. Liu Qiyuan, the "Ark" builder, said, "The concept originated twenty years ago. The Tangshan earthquake had flattened our house, so I wanted to build a shelter that wouldn't fall. Then in 2004, I saw the tsunami in Indonesia that killed so many people.Then I realized it should be something that could withstand the earthquake and float on water." Liu is hoping to use his invention as a life boat on the sea.He's planning to test his product on the water next year. It turns out that rumor, though false, is good for business. Doomsday discounts and products are hot on... Question: Liu Qiyuan quit his job and built his "ark" because _ . Options: A: he wanted to make preparations for destructive natural disasters B: he was tired of making money from his furniture business C: he was almost killed in Indonesia in 2004 D: he believed that the world was going to end on Dec. 21, 2012

I'm taking a test and have to guess the right answer to the question after the article. Article: We often use the words growth and development as if they meant essentially the same thing. But this may not always be the case. One can easily imagine instances in which a country has achieved higher levels of income (growth) with little or no benefit coming to most of its citizens (development). In the past, most development policies were aimed increasing the growth rate of income per capita. Many still are, based on the theory that benefits of economic growth will come to all members of society. If this theory is correct, growth should promote development. By the early 1970s, however, the relationship between growth and development was being questioned. A major study by the World Bank in 1974 concluded that it is now clear that more than a decade of rapid growth in underdeveloped countries has been of little benefit to a third of their population. The World Bank study indicated that increases in GNP per capita did not promise important improvements in such development indicators as nutrition, health, and education. Although GNP per capita did indeed rise, its benefits come down to only a small part of the population. This realization gave rise to a call for new development policies. These new policies favored agriculture over industry, called for domestic redistribution of income and wealth, and encouraged programs to satisfy such basic needs as food and shelter. In the late 1970s and early 1980s, the international macroeconomic crises of high oil prices, worldwide recession, and third world debt forced attention away from programs designed to get rid of poverty. However, the lesson remains: economic growth does not promise economic development. Efforts may be required to change growing output capacity into economic benefits that reach most of a nation's people. Question: As to the relationship between growth and development, what can we infer from the passage? Options: A: Development is a reliable measure of growth. B: Growth always brings about development. C: Development is not necessarily the result of growth. D: Growth and development refer to the same thing.

I'm taking a test and have to guess the right answer to the question after the article. Article: The canopy, the upper level of the trees in the rain forest, holds too much of climbing mammals of moderately large size, which may include monkeys, cats, civets, and porcupines. Smaller species, including such as nice and small squirrels, are not as common overall in high tropical canopies as they are in most habitats globally. Small mammals, being warm blooded, suffer hardship in the exposed and uncertain environment of the uppermost trees. Because a small body has more surface area per unit of weight than a large one of similar shape, it gains or loses heat more rapidly. Thus, in the trees, where protection from heat and cold may be scarce and conditions may be changeable, a small mammal may have trouble maintaining its body temperature. Small size makes it easy to scramble among twigs and branches in the canopy for insects, flowers, or fruit, but small mammals are defeated, in the competition for food, by large ones that have their own strategies for browsing among tbod-rich twigs. The weight of an ape hanging below a branch draws the leaves down so that fruit-bearing leaves drop toward the ape's face. Walking or leaping species of a similar or even larger size access the outer twigs either by breaking and gaining the whole branch or by catching hold of hard branches with the feet or tail and picking food with their hands. Small climbing animals may reach twigs readily, but it is harder for them than for large climbing animals to cross the wide gaps from one tree top to the next that typify the high canopy. A gibbon can hurl itself farther than a mouse can: it can achieve a running start, and it can more effectively use a branch as a springboard . The forward movement of a small animal is seriously reduced by the air friction against the ly large surface area of its body. Question: Which of the following questions does the passage answer? Options: A: How is the rain forest different from other habitats? B: How does an animal's body size influence an animal's need for food? C: Why does rain forest provide an unusual variety of food for animals? D: Why do large animals tend to dominate the upper canopy of the rain forest?
