PROBLEM: Article: Most people think of a camel as an obedient beast of burden, because it is best known for its ability to carry heavy loads across vast stretches of desert without requiring water. In reality, the camel is considerably more than just the Arabian equivalent of mule . It also possesses a great amount of intelligence and sensitivity. The Arabs say that camels are so acutely aware of injustice and ill-treatment that a camel owner who punishes one of the beasts too hard finds it difficult to escape the camel's revenge .Apparently, the animal will remember an injury and wait for an opportunity to get revenge. In order to protect themselves from the vengeful beasts, Arabian camel drivers have learned to trick their camels into believing they have achieved revenge. When an Arab realizes that he has excited a camel's rage, he places his own garments on the ground in the animal's path. He arranges the clothing so that it appears to cover a man's body. When the camel recognizes its master's clothing on the ground, it seizes the pile with its teeth, shakes the garments angrily and steps on them in a rage again and again. In the end, after its rage has died away, the camel leaves, believing its revenge is completed. Only then does the owner of the garments comes out of hiding, safe for the time being, thanks to this clever trick.
Answer: camels try to punish people who ill-treated them

SOLUTION: From this passage we can conclude that _

PROBLEM: Article: There are some things humans can go without. We can lose a kidney or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can _ without stomachs. One such fish is the stout longtom. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost. The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. It teeth are not good at cutting fish into pieces, so it swallows fish whole. Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish. Day's results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin that can break down proteins without acid -- although the approach is less efficient than using a stomach. Because it's a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein. Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is "a fairly expensive organ to run". This perhaps explains why some animals have got rid of theirs.
Answer: digests the smaller fish in its body

SOLUTION: Ryan Day ran the chemical tests in order to find out how the longtom _ .

PROBLEM: Article: Some weightloss camps, which are rare in China just a few years ago,have multiplied in Beijing, Qingdao, Shenzhen,and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight.Of these, 90 million--about 7 percent--are obese . Experts say the obesity epidemic is spreading to children, though more slowly than in adults. The obesity, they say, will do harm to the health of China' s citizens and economy."We're seeing a very large number of teenagers who are quite heavy and aren't moving much," said Barry Popkin, a nutrition professor. Popkin carries out an ongoing healthandnutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight "quite quickly." In just ten years China's childhood obesity rate has doubled,with the greatest gains coming in urban areas."In big cities it's a big problem." Some experts blame the extra fat on a range of factors, many of them tied to China' s rapidly changing economy and culture. The diets of Chinese adults and children are far higher in meats, fish, eggs, dairy products, fats and sugars than ever before. In addition,kids--especially city dwellers--are more today and spend more time indoors in front of homework, television,computer games, and the Internet. Shuwen Ng,a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features. China' s childhood obesity rate stillfall behind that of the United States, where some 15 percent of kids are said to be obese. But the longterm effects are equally serious.
Answer: America' s childhood obesity rate is lower than China's
