Read the following article and answer the question. Article: Global Positioning Systems(GPS) are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two. We spoke to Mr. Brown by Skype . He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. BARRY BROWN: "And they just plugged in an address and then set off to their destination. And, then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'." Mr Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. BARRY BROWN: "One problem with a lot of the GPS units is that they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place." Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people's cars. They wrote a paper based on their research. It is called "The Normal, Natural Troubles of Driving with GPS." It lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues related to when GPS commands are... Question: What is the disadvantage of small screens in GPS equipment according to the text? Answer:
****
A: They just provide the next turn.

Read the following article and answer the question. Article: I entered college in China in 1981. Many things seemed to remain the same. For many things are dominated by one thing: the national entrance examination to get into college. In my year, about 4% high school students went to college. Now the number is 22%, as compared to 40% in the US. The significant increase in the entrance rate doesn't seem to have relieved the anxiety. As a parent to a freshman college student, I can prove that junior and senior years in high school are not much fun even for students in the US. Once a country has vastly increased the rate of college entrance, students will still want to get into "better" colleges. _ , no matter where you are. The NYT Magazine article also mentioned the Soviet-style over-specialized education in Chinese colleges. My class in college had maybe 60 students specialized in compressors, another 60 students specialized in refrigeration, and yet another 60 students specialized in welding . I was among the 60 specialized in mechanics. I cannot recall the numbers exactly, but you get the picture. It really wasn't as terrible as it sounds. In order to specialize in mechanics, we had to study math, physics and chemistry. We studied electrical circuits, alloy treatment, mechanical drawing, Fortran. We even had a continuous stream of humanity courses: history of communist party, political economics... I'm not sure I enjoyed all the courses, but I cannot claim that these courses damaged my brain, either. I remember some of the humanity courses required writing, which turned out to be a useful skill. As a consequence of specialization, we did learn a lot of mechanics. By the end of college, we had courses on analytical mechanics, strength of materials. I often feel sorry for American students in my undergraduate class, knowing that strength of materials will be their first and last course in the mechanics of materials. So many beautiful sights unseen! But they also seem to turn out to be OK. A liberal and superficial eduction doesn't damage their brains, either. All... Question: What is the author's attitude towards his courses? Answer:
****
A: He doesn't think that all of them are necessary.

Problem:OPTIONS:
- the population of the world is decreasing fast
- people use too many man-made materials
- we have more and more industry
- we are producing more cars, trucks and buses

Read the following article and answer the question. Article: Our surroundings are being polluted faster than nature and man's present efforts cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials. What can explain and solve this problem? The fact is that pollution is caused by man--by his desire for a modern way of life. We make "increasing industrialization" our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem. Isn't it time we stopped to ask ourselves where we are going--and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, "I've some good news and some bad news. The good news is that we're making rapid progress at 530 miles per hour. The bad news is that we're lost and don't know where we're going." The sad fact is that this becomes a true story when spoken of our modern society. Question: Man cannot prevent the world from being polluted mainly because _ . Answer:
****
A:
we have more and more industry
