[Q]: Article: Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man's interference can be seen in what happened many years ago in the forest of the Kaibab plateau of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead. The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and _ . In 1882 a visitor noted, "We, who ... have wandered through its forests and parks, have come to regard it as the most enchanting region it has ever been our privilege to visit." This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly. Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer's enemies. In 25 years' time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000. The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd ,but a far greater loss resulted from starvation and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.
Answer: interfering with natural cycle of forest life
[A]: The destruction of the environment of the Kaibab resulted from _

[Q]: Article: After years of hearing drivers complain about scratches on their cars, Japan's Nissan Motor Company has officially announced the next big thing--a paint that not only resists scratches and scrapes, but actually repairs itself within a few days. The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris or even on-purpose destruction. The automaker admits its results vary depending on the temperature and the depth of the damage, but adds "this is the only paint like it in the world, and tests prove it works." Minor scratches, the most common type, are said to slowly fade over about a week. And once they're gone, there is no trace that they were ever there. The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period. Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents. But the complete auto-healing won't come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 US to the price of a car. It plans to use its new chemical mixture only on its _ in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores as well.
Answer: marketing this paint in Europe is not under way
[A]: From the article, we can find that _ .

[Q]: Article: Two-thirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to stole water and provide power. In the US,there are more than 85,000 dams,disrupting large and small rives, and in most cases transforming natural flow.The most famous of these,the Hoover Dam, constructed in the l930's,is mainly responsible for the fact that the Colorado River no longer reaches the ocean. Dams, besides all their attractive benefits, also have negative impacts. Creating a reservoir means a large area must be flooded. Communities may lose their land, houses and culturally impotent sites. Environmentally, the new reservoir can be a paradise for wildlife, especially birds. However, it can cause greenhouse gas emissions and poison the water for fish. Also, the dramatic rise and fall of water levels during dam releases is too extreme for plains and animals to cope with, resulting in dead zones around the shores of reservoirs. Fish that lay their eggs in the shallows, for example, may find a few hours later that those sites are high and dry. Dams don't just block water flow. They also prevent fish migrations, and are a barrier to sediment flows. Instead of rushing downriver, sediments get backed up against the dam wall, which cause the reservoir level to increase over time.However, sediments which are rich in nutrients have become a problem. The fertility of the entire system can be influenced, with soils lost during seasonal rains not being replaced. Perhaps the biggest problem can be seen in deltas , often host to large cities,which are sinking into the oceans. Groundwater is being extracted to feed the city, causing the urban weight to sink and sediments washed away by the ocean are no longer being replaced. The result is that sea level rise in cities from Shanghai to Alexandria.
Answer: find it easier to deal with the rise of water
[A]:
With many dams built across rivers, fish will _
