Read the following article and select the best answer. Article: If I see one more article about how wonderful alternative energy is compared to oil, I will flip . Alternative energy sources can be good---- very good in fact. And it's pretty obvious that we're going to need them, and that our dependence on oil is a Bad Thing. But accepting that does not mean accepting that any kind of alternative energy is a good thing. To be a good thing, it has to have three properties: 1) It has to help reduce our dependence on oil, 2) It has to be no worse for the environment, and 3) It has to be economically practical. Many of the things praised meet one or even two of those properties. Solar panels, for example. They can reduce our need for oil, at least in certain regions, and they're certainly not bad for the environment. But they're expensive. If you spend the money to make your home solar-powered, you probably won't get back your costs for at least 15 years, which approaches the lifespan of the panels. Certainly we need to clean up our act big time and find workable sources of alternative energy. But we also have to keep in mind that every one of these alternative-energy sources comes at a cost, which is something people seem to forget. They hear the phrase "alternative energy" and automatically assume it's got to be good. But green isn't always good, and oil isn't always bad. One seemingly "green" technology that pops up again and again is electric cars. It is praised by well-meaning people as good for the environment and a way to reduce our oil dependence, especially as oil prices continue to rise. Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins. People in California love to talk about " zero-emissions vehicles", but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---- usually coal, oil,... Question: It can be inferred from the text that _ . - being green is good and should be encouraged in communication - electric cars are not clean in that we get electricity mainly by burning something - zero-emissions vehicles should be chosen to protect our environment - electric cars are now the dominant vehicle compared with gasoline-powered cousins
(Answer)
electric cars are not clean in that we get electricity mainly by burning something

Read the following article and select the best answer. Article: If you know exactly what you want, the best way to get a job is to get specialized training. A recent survey shows that companies like graduates in such fields as business and health care who can go to work immediately with very little on-the-job training. That's especially true of booming fields that are challenging for workers. At Cornell's School of Hotel Administration, for example, bachelor's degree graduates get an average of four or five job offers with salaries ranging from the high teens to the low 20s and plenty of chances for rapid advancement. Large companies, especially, like a background of formal education coupled with work experience. But in the long run, too much specialization doesn't pay off. Business, which has been flooded with MBAs, no longer considers the degree an automatic stamp of approval. The MBA may open doors and command a higher salary initially, but . As further evidence of companies gradually losing faith in specialized degrees, Michigan State's Scheetz mentions a pattern in hiring practices. Although companies tend to take on specialists as new hires, they often seek out generalists for middle and upper-level management. "They want someone who isn't constrained by details to look at the big picture," says Scheetz. This sounds like a formal statement that you approve of the liberal-arts graduates. Time and again labor-market analysts mention a need for talents that liberal-arts majors are assumed to have: writing and communication skills, organizational skills, open-mindedness and adaptability, and the ability to analyze and solve problems. David Birch, manager of the Boston Red Sox, claims he does not hire anybody with an MBA or an engineering degree, "I hire only liberal-arts people because they have a less-than-canned way of doing things," says Birch. For a liberal-arts degree, students focus on some basic courses that include literature, history, mathematics, economics, science, human behavior--plus a computer course or two. With these useful and important courses, you... Question: David Birch claims that he only hires liberal-arts people because they _ . - are more capable of handling changing situations - can stick to established ways of solving problems - are thoroughly trained in a variety of specialized fields - have attended special programs in management
(Answer)
are more capable of handling changing situations
