Read the following article and select the best answer. Article: The Norwegian Government is doing its best to keep the oil industry under control. A new law limits exploration to an area south of the southern end of the long coastline; production limits have been laid down (though these have already been raised); and oil companies have not been allowed to employ more than a limited number of foreign workers. But the oil industry has a way of getting over such problems, and few people believe that the Government will be able to hold things back for long. As one Norwegian politician said last week: " We will soon be changed beyond all recognition." Ever since the war, the Government has been carrying out a program of development in the area north of the Arctic Circle. During the past few years this program has had a great deal of success. Tromso has been built up into a local capital with a university, a large hospital and a healthy industry. But the oil industry has already started to draw people south, and within a few years the whole northern policy could be in ruins. The effects of the oil industry would not be limited to the north, however. With nearly 100 percent employment, everyone can see a situation developing in which the service industries and the tourist industry will lose more of their workers to the oil industry. Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad. The real argument over oil is its threat to the Norwegian way of life. Farmers and fishermen do not make up most of the population, but they are an important part of it, because Norwegians see in them many of the qualities that they regard with pride as essentially Norwegian. And it is the farmers and the fishermen who are most critical of the oil industry because of the damage that it might cause to the countryside and to the sea. Question: In the south, one effect to the development of the oil industry might be _ . - a large reduction on unemployment - a growth in the tourist industry - a reduction in the number of existing industries - the development of a number of service industries
a reduction in the number of existing industries

Read the following article and select the best answer. Article: Have you heard of snake robots? Scientists and doctors are already using tiny snakes that coil through the human body armed with sharp surgical tools to perform operations on hearts, prostate cancer, and other diseased organs. The snake robots that carry tiny cameras, scissors and forceps, and even more advanced sensors are being developed. The next generation of the robots will be wireless, and will explore inside your body on their own--- not attached to any cables. For now, they are powered by cables that humans control. Experts say the day is coming when some robots will roam around the body on their own. But the experts in robotics say the new creations work best when they are designed for very specific tasks. Howie Choset has been researching and building robots, particularly snake robots. He believes that his snake robot and others like it can help reduce medical costs by making complex surgery faster and easier. Choset says his new design is smaller and more flexible than earlier models. The size of surgical robots allows surgeons to operate with far less damage to the body, helping the patient heal faster. Choset has also built larger snake robots designed for search and rescue, or just exploration. They can climb poles and trees and then look around through a camera in the head and slither through places that humans cannot reach. " We sent our snake robots into these caves in the Red Sea to look for evidence of ancient Egyptian ships," he said. " To me, archeology is like search and rescue, but everyone has been dead for 5,000 years." The doctors are very excited about the potential for surgical robots to do things that humans can't do. The variety of sensors available for surgical robots keeps expanding. As they get smaller, maybe one day they will be able to test chemicals or blood in the body, or even the electrical connections in nerves. Question: Which of the following is true, according to the passage? - Snake robots are only used in the medical field. - Snake robots can reduce the patients' medical costs. - Scientists are uncertain about the prospects for snake robots. - Scientists are forced to spend a lot of time researching snake robots.
Snake robots can reduce the patients' medical costs.

Read the following article and select the best answer. Article: Intellectual property (IP) is a product of the mind that has commercial value. The concept dates back to 1623, when the first patent law to protect IP rights was passed. IP rights protect an artist from having his/her creative ideas copied by another. For example, if somebody generated an idea for a novel, that idea is protected by IP rights. If someone else wishes to represent the idea or develop it further, he/she must consult the original artists, who will normally be rewarded financially for its use. Back in the 17thcentury, IP rights were primarily carried out to protect newly developed manufacturing processes against stealing, but today intellectual property rights are also enjoyed by those who create music, art and literature. In recent years, IP rights have been the focus of a great deal of discussion because of a technology which looks set to weaken them altogether: the Internet. Many years ago, if you wanted a recoding of a song, you would have to purchase it from a music store; if a novel, from a book store. In those days, IP rights were easily protected since it was very difficult to obtain intellectual property without paying for it. However, a lot of IP, including songs, films, books and artwork, can be downloaded today free of charge using the internet. This practice has now taken the world by storm, dramatically affecting the way in which we view IP rights. Question: What do we know about the Internet according to the passage? - It does not affect the way we understand IP rights. - It sells songs and films. - It makes IP rights harder to protect. - It prevents the production of artwork.
It makes IP rights harder to protect.
