Read the following article and select the best answer. 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: Which of the following can be used as the best title of the passage? - Alaska--A Frozen Land - Is Alaska Sinking? - Pollution and Global Warming - Alaska is polluted.

Read the following article and select the best answer. Article: One windy spring day, I observed young people having fun using the wind to fly their kites. Multicolored creations of varying shapes and sizes filled the skies like beautiful birds dashing and dancing in the exciting atmosphere above the earth. As the strong winds gusted against the kites, a string kept them in check. Instead of blowing away with the wind, they arose against it to achieve great heights. They shook and pulled, but the controlling string and the clumsy tail kept them in tow , facing upward and against the wind. As the kites struggled and trembled against the string, they seemed to say, "Let me go! Let me go! I want to be free!" They flew beautifully even as they fought the forced restriction of the string. Finally, one of the kites succeeded in breaking loose. "Free at last," it seemed to say. "Free to fly with the wind." Yet freedom from control simply put it at the mercy of an unsympathetic gentle wind. It flew ungracefully to the ground and landed in a twisted mass of weeds and string against a dead bush. "Free at last". Free to lie powerless in the dirt, to be blown helplessly along the ground, and to settle down lifeless against the first roadblock. How much like kites we sometimes are. There always exist misfortunes and restrictions, rules to follow from which we can grow and gain strength. Prohibition is a necessary counterpart to the winds of opposition. Some of us pulled at the rules so hard that we never fly fast to reach the heights we might have obtained. If we keep all the commandment , we will never rise high enough to get our tails off the ground. Let us each rise to the great heights, recognizing that some of the prohibitions are actually the steady force that helps us climb and achieve. Question: What didn't happen to the freed kite? - It kept flying freely in the air. - It lay powerless in the dirt. - It was trapped in a dead bush. - It was blown helplessly around.
(Answer)
It kept flying freely in the air.

But my son is a persistent little fellow!I had to give in. Building that toy boat took me about three hours. By the time it was finished,I realized that those three hours spent building that boat were first hours of mental relaxation and peace that I had had in months!I realized that it is difficult to worry while you are busy doing something that requires planning and thinking. In my case,building the boat had knocked worry out of the ring. So I determined to keep busy." "The following night,I made a list of jobs that ought to be done. Scores of items needed to be repaired. Amazingly,I had made a list of 242 items that needed attention. During the last two years I have completed most of them. I am busy so that I have no time for worry."
