Article: Farmers can produce more by planting several different crops in the same field.But their success depends on which crops they plant together and how they mix them in the filed.In the past, the only way the farmers could learn which crops grow best together is to plant them and wait for the results.Now, however, a computer can give them answers.A new computer program written by Dr John Vanderwell of Michigan University can tell a farmer which plants grow well together and which do not.It can tell him how to plant the different crops; if he should plant each in a separate row, or mix the crops in the same row.It can tell the farmer how changes in planting each of the crops will affect the production of all of them.And it can tell him which plants can help reduce losses from diseases.

Read the following article and select the best answer. Article: Listening to a radio broadcast in a foreign language is difficult for many of us. We may have studied the language for several years, and are able to read it, perhaps even write in it. But listening and understanding the spoken language require special skills. Some people have a natural ability that helps them to learn a language quickly, while others must study for a long time. Everyone, however, can improve his or her listening skills with practice. We are good listeners in our own language because we have had years of practice. We understand the grammar and the language. We know what to expect a person to say to us in almost any situation. We have been in similar situations many times, and we have heard it all before. We can understand it, even if we do not listen carefully. But this is not true with a foreign language. We must listen with our full attention. And we must try not to let the cultural style of our language affect our understanding of the foreign language. Listening to a foreign language broadcast is easier if we know something about it. There are clues that can help us. One clue is the time of a day. Morning programs usually contain many short items of news, information or entertainment. The items are short because most of us are getting ready to go to work in the morning. Often we do not have time to listen to long programs. Evening programs are different. There is time for more details about the subjects discussed. We can get a clue about the program from the music at the beginning, but we must be familiar with the music of the foreign culture. The kind of music--serious and slow, or fast and light--can tell us what kind of program to expect. The name of the program can give us good information about what it will contain. Another good clue is the broadcaster. The more we listen to the same person, the easier it will be to understand him. His speaking style will become familiar to us. Further, the broadcaster provides clues to the organization of the broadcast at the beginning of the...

Q: Read the following article and select the best answer. Article: The world is filled with smart, talented, educated and gifted people. We meet them every day. A few days ago, my car was not running well. I pulled it into a garage and the young mechanic had it fixed in just a few minutes. He knew what was wrong by simply listening to the engine. I was amazed. The sad truth is, great talent is not enough. I am constantly shocked at how little talented people earn. I heard the other day that less than 5 percent of Americans earn more than $100, 000 a year. A business consultant who specializes in the medical trade was telling me how many doctors and dentists struggle financially. It was this business consultant who gave me the phrase, "They are one skill away from great wealth." There is an old saying that goes, "Job means' just over broke ' ". And unfortunately, I would say that the saying applies to millions of people. Because school does not think financial intelligence is intelligence, most workers" _ ". They work and they pay the bills. Instead I recommend to young people to seek work for what they will learn, more than what they will earn. When I ask the classes I teach, "How many of you can cook a better hamburger than McDonald's?" almost all the students raise their hands. I then ask, "So if most of you can cook a better hamburger, how come McDonald's makes more money than you?" The answer is obvious: McDonald's is excellent at business systems. The reason so many talented people are poor is because they focus on bui1ding a better hamburger and know little or nothing about business systems. The world is filled with talented poor people. They focus on perfecting their skills at building a better hamburger rather than the skills of selling and delivering the hamburger. Question: The main purpose of the author is to tell us _ . - how young people can find a satisfactory job - what schools should teach students - why so many talented people are poor - how McDonald's makes much money
A: why so many talented people are poor
