Article: For poets, bird song is a beautiful expression of nature in full bloom. But for scientists, the chirps of birds are far more meaningful than just pretty sounds. Latest studies show the way that young birds learn to sing is similar to that of a human baby learning to speak. "The question we're trying to answer is how a young bird learns its song," says Professor Michale Fee of MIT. Bird's creative, trial-and-error type of learning provides an ideal model for studying similar processes in humans. An example is how a baby's babble turns into the recognizable syllables of mama and papa. Also the part of the brain that is involved in bird song is very similar to that of a human. So birds may have something to teach us about our own brains, Fee said. The study shows that young birds like to create new and imperfect songs. Gradually, the youngsters' songs become less different and more similar to the sound of their parents. Scientists disabled part of a young finch's brain and stopped the learning in midstream. The bird still sings. But never learns the right songs. Fee's team found that the part of the brain involved is called the anterior forebrain pathway. Its neurons produce random bursts that make the young bird make new sounds and compared it with that of their parents. They also find out that once a bird is old enough that part of the brain will be less active. The study does not enable us to really understand the meaning of bird language. But Fee believes it will eventually be applied to human brain diseases, such as Parkinson's disease. Question: Parkinson's disease is mentioned here to _ . Yes or no, is the answer "exemplify human brain disease"?
No

Q: Article: On the old-time farm in America, there were chickens, cows, pigs and horses. But there were very few machines. Most of the work was done by the farm family. Sometimes more workmen were needed in busy seasons. Work done by horses took up 79 percent; by men, 15 percent; and machine work only took up 6 percent. Today all that has changed. On many modern farms machines now will do 96 percent of the work, while man does 3 percent. As for horses, they do 1 percent of the whole work. The children go to school by bus every morning; the parents work on the farm or in the house and other people's help is hardly needed. Their work has been replaced by a whole army of farm machines. Question: What has changed the farmer's work? Yes or no, is the answer "The machines."?
A: No

Article: Want to live longer? Win an Oscar. A new study says that actors who received the award earn more than larger paychecks. So when 94-year-old Katharine Hepburn once remarked that she was respected internationally "like an old building", she had no idea that her four Oscars directly influenced her longevity . The study says winning actors will live 3.9 years longer than their losing counterparts . Actors who have won more than once, like Hepburn, live up to six years longer than those who were nominated but never won. "We found that they died from the same things we all die from--cancer, heart disease, but they fought them a bit longer and diseases came a bit later," says Dr. Donald Redelmeier, the leading author of the study. Redelmeier says the sense of success and satisfaction makes one's soul become more full of life. "We are not saying that you will live longer if you win an Oscar," explains Redelmeier, "or that people should go out and take acting courses. Our main conclusion is simply that social factors are important." The study's implied conclusion, he says, is that doctors should ask about their patients' personal feelings because mental well-being is related to physical health. Redelmeier says he got the idea for the study when he watched a glowing Gwyneth Paltrow win an Oscar in 1999 for her role in Shakespeare in Love. Redelmeier says, "She looked more full of life than anyone I had seen." "We found, too, those that had multi-nominations and no win had the same life expectancy as those with just a single nomination and no win," Redelmeier adds. Question: The longevity of Oscar winners mainly has something to do with _ . Yes or no, is the answer "mental factors"?
(Answer)
No
