Read the following article and answer the question. Article: Houses fall down. Trees fall over. Large holes form in the ground. Could Alaska be sinking? That's what some villagers in Alaska have been asking themselves recently--and scientists think they know why. Warmer temperatures may be causing Alaska's frozen ground to thaw . About 85 percent of Alaska's land surface has _ . Permafrost supports the ground above it--including trees, houses, and roads. But why is the permafrost thawing? Some scientists say that human-caused pollution is leading to global warming. And most scientists agree that Alaska has been getting warmer. They say that the warmer temperature is causing permafrost to thaw in some areas. The thawing permafrost can cause problems for people, plants, and animals. "The collapsing is a problem in the villages in Alaska which are built on permafrost, and some of them may have to move to safer ground, where there is no permafrost," Weller said. The Alaskan town of Glennallen saw its old post office collapse. And, according to James Walters, a permafrost expert at the University of Northern Iowa, house-moving companies have been very busy. "Melting permafrost can also destroy trees and forests," Weller said. "When holes in the ground form, trees fall into them and die. This could turn a forest into a swamp , and animals which need the forest will have to move elsewhere." The melting could cause "severe problems." Weller says: "This could take hundreds of years, but in the end Alaska will look quite different from what it looks like now." Question: The following are the results of melting permafrost except _ . Answer:
OPTIONS:
- holes are formed in the ground
- forest will be turned into meadows
- some animals have to go elsewhere
- more water will be needed by people and animals

Answer: more water will be needed by people and animals

Read the following article and answer the question. Article: London's newest skyscraper is called the Shard and it cost about 430 million pounds to build. At a height of almost 310 metres, it is the tallest building in Europe. The Shard has completely changed the appearance of London. However, not everyone thinks that it is a change for the better. The Shard was designed by the famous Italian architect Renzo Piano. When he began designing the Shard for London, Piano wanted a very tall building that looked like a spire * He wanted the glass surfaces to reflect the sky and the city. The sides of the building aren't regular. So the building has an unusual shape. It looks like a very thin,sharp piece of broken glass. And that is how the building got the name: the Shard. Piano says that the spire shape of the Shard is part of a great London tradition. The shape reminds him of the spires of the churches of London or the tall masts of the ships that were once on the river Thames. The Shard has 87 floors. At the top, there is an observatory. At the moment the building is empty, but eventually there will be a five-star hotel. There will also be top quality restaurants, apartments and offices. Before building work began, a lot of people didn't want the Shard though the plans were approved. Now they are still unhappy about the Shard. Some critics say that such a tall skyscraper might be good in a city like New York, but not in London. They say that the best thing about the Shard is its spire shape. But that is the only thing. There is no decoration, only flat surfaces. The Egyptians did that 4,500 years ago. They also think the Shard is too big for London. It destroys the beauty of the city. Other critics don't like what the Shard seems to represent. They say that the Shard shows how London is becoming more unequal. Only very rich people can afford to buy the expensive private apartments and stay in the hotel. But the people who live near the Shard are among the poorest in London. So the Shard seems a symbol of the division in society between the very rich and the poor. The... Question: When he designed the Shard, Piano wanted it to . _ Answer:
OPTIONS:
- change London's skyline
- inherit London's tradition
- imitate the Egyptian style
- attract potential visitors

Answer:
inherit London's tradition
