Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions. When corals are mentioned, many people think of rock-life forms in the sea filled with colorful fish. But corals are made up of hundreds of thousands of small organisms which live and feed like any other sea life. For the past five years, researchers in Hawaii and Australia have been engineering corals inside a lab to see if they could better resist the effects of climate change. They say it is now time to see how their creations perform in nature. The scientists say climate change linked to human causes has led to warming oceans that can harm sea life. They say if the more heat-resistant corals they developed do well in the ocean, the method can be used to help save suffering and dying reefs. The team tested three methods for making corals that would be strong and healthy in nature. One was the method of selective breeding. This method involves choosing parents with desirable characteristics for reproductive purposes. A second method subjected the corals to increase temperatures to condition them to be able to survive in warm ocean environments. The third involved making changes to the algae that provide corals with necessary nutrients. The leader of the project, University of Hawaii researcher Kira Hughes, said all the methods proved successful in the lab. She told The Associated Press that some scientists might worry that such methods go against the natural processes of nature. But with the planet continuing to warm more and more, she does not see any better options. “We have to intervene in order to make a change for coral reefs to survive into the future,” Hughes said. When ocean temperatures rise, corals release algae that supplies nutrients and gives them color. This causes them to turn white, a process called bleaching. When this happens, corals can quickly become sick and die. But for years, scientists have been observing corals that have survived bleaching, even when others have died on the same reef. They are now focusing on those healthy survivors and hoping to further increase their resistance to heat. Those corals were used as the parents for the newly created kinds.

- Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35. The concept of traffic-free shopping areas goes back a long time. During the Middle Ages, traffic-free shopping areas were built in Middle Eastern countries to allow people to shop in comfort and, more importantly, safety. As far back as 2000 years ago, road traffic was banned from central Rome during the day to allow for the free movement of pedestrians. The modern, traffic-free shopping street was born in Europe in the 1960s, when both city populations and car ownership increased rapidly. Dirty exhaust from cars and the risks involved in crossing the road were beginning to make shopping an unpleasant and dangerous experience. Much believed the time was right for experimenting with car-free streets, and shopping areas seemed the best place to start. At first, there was resistance from shopkeepers. They argued that people would avoid streets if they were unable to get to them in their cars. When the first streets in Europe were closed to traffic, there were even noisy demonstrations, as many shopkeepers predicted they would lose customers. With the arrival of the traffic-free shopping street, many shops, especially those selling things like clothes, food and smaller luxury items, prospered. Unfortunately, shops selling furniture and larger electrical appliances actually saw their sales drop. Many of these were forced to move elsewhere, away from the city center.
