Article: Economics is the study of how societies with limited resources decide what to produce, how to produce and for whom to produce. What, how, and for whom to produce are problems all over the world because human needs are practically unlimited, but all societies have only limited quantities of resources that can be used to produce goods or services. A knowledge of basic economics is important for understanding both the problems and opportunities that will face the world economy in the 21st century.

Suppose someone decides to get a part-time job so he can earn enough money to buy a car. He will have the benefit of owning the car, but he will pay a cost in terms of the leisure hours he gives up for working so as to pay for the car and keep it in good condition. After weighing his choice in cost-benefit terms, he may decide he does not need a car any more. Question: Economics can help one make better decisions because he learns _ .

Article: Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later. I am one of those unfortunate people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the spot I was heading for. I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit that they didn't know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you can not possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite direction to that in which you should be going. If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results. Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decide it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting. Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked. Question: Who showed the right way to the interviewee according to the passage? Yes or no, is the answer "Someone we don't know."?
No

Q: Article: United States President George W. Bush is expected to issue a directive in the next few weeks. It will give the US Air Force a green light for the development of space weapons, US media reported last week. This would potentially start a new global arms race, some experts have warned. To keep that from happening, last Wednesday the White House explained that it was not considering putting weapons in space. It said it was making a shift inprefix = st1 /USspace policy to allow for protection of satellites. But some defense analysts and arms control advocates argue that the policy will pave the way for the US to put both defensive and offensive ( ) weapons in space. "No one should be fooled," said Theresa Hitchens, an American weapons expert. The USis now restricted by a 1996 directive signed by President Bill Clinton. Plans for space weapons were vetoed by the Clinton cabinet. The directive emphasized the peaceful use of space , in agreement with almost unanimous ( ) global opinion. The USmilitary has placed importance on space and has sent up numberous satellites for troop communications and to provide intelligence and data to guide bombs to their targets. The US Air Force wants to develop space- based weapons that could strike targets anywhere in the world within 90 minutes of receiving the order to open fire. These new weapons under development cover a wide range. They include hunter- killer satellites and orbiting weapons. And they use lasers, radio waves, or even dense metal tubes, known as " Rods from God", dropped from space to do the damage. There are many barriers to the setting up of this kind of program, experts say. First is the coast. It is estimated that the budget may be US $220 billion to US $ 1 trillion . The technical difficulties of developing reliable space weapons are also a problem. And, the program will draw strong criticism from around the world. Experts worry about starting a space arms race. Question: After reading this passage, it can be inferred that " _ ". Yes or no, is the answer "George W. Bush's directive to be issued will be against global opinions"?
A: No

Article: Dear Editor, I am writing to ask what has happened to our youth. They are not as polite, hard-working or clever as my generation. I will give you two examples. Last Friday, I got on the underground at 9.15a.m. It was very busy so there were no free seats. There were some teenagers sitting on the seats nearest me. I didn't know why they were not at school. They were talking loudly and laughing. It was difficult to read my newspaper with all the noise. A heavily pregnant woman and her daughter got on at the next stop, with lots of shopping bags. I expected the teenagers to let them sit down. They saw the woman but did nothing. I had to ask them to give her a seat. They reluctantly did so but give me a rude look. I got off at the next stop and was glad that the teenagers didn't follow me. Last Saturday, I had dinner with my friend's family. I was expecting to meet his children, who I hadn't seen for ten years. During dinner, we started talking about world politics. It soon became clear that they didn't know much. They couldn't tell me the name of the King of Spain or the President of Italy. All they knew about was the Internet and which singers were the most beautiful. In my day, students knew the kings, queens and presidents of every country in Europe. I worry about the future of Germany. How could these young people become responsible workers and parents? They sit around Macdonald's after instead of going to the library like I did at their age. Maybe they have too much money. Perhaps another reader can give us an idea about what to do with this"lost generation". Franz Vogts Hamburg Question: Franz Vogts was not pleased at the dinner because _ . Yes or no, is the answer "the children did not know much about world politics"?
(Answer)
No
