Q: Read the following article and select the best answer. Article: Our love of music and appreciation of musical harmony is learnt and not based on natural ability, a new study by University of Melbourne researchers has found. The researchers said previous theories about how we appreciate music were based on the physical functions of sound, the ear itself and a born ability to hear harmony. The study shows that musical harmony can be learnt, and it is a matter of training the brain to hear the sounds. So if you thought that the music of some foreign culture (or Jazz) sounded like the crying of cats, it's simply because you haven't learnt to listen by their rules. The researchers used 66 volunteers with a range of musical training and tested their ability to hear combinations of notes to determine if they found the combinations familiar or pleasing. They found that people needed to be familiar with combinations of notes. If they couldn't recognize the notes, they found the notes _ . This finding put an end to centuries of theories claiming that physical functions of the ear determine what we find attractive. The study found that trained musicians were much more sensitive to unpleasant notes than non-musicians. When they couldn't find the note, the musicians reported that the sounds were unpleasant, while non-musicians were much less sensitive. This shows the importance of training or nurturing the brain to like particular sound of combinations of notes, like those found in jazz or rock. Depending on their training, a strange chord sound was pleasant to some musicians, but very unpleasant to others. This showed us that even the ability to hear a musical note is learnt. To confirm this finding, they trained 19 non-musicians to find the notes of a random selection of western chords. Not only did the participants' ability to hear notes improve rapidly; the chords they had learnt sounded more pleasant--regardless of how the chords were played. The question of why some combinations of musical notes are heard as pleasant or unpleasant has long been debated. "...

Q: Read the following article and select the best answer. Article: Listen carefully, working people, we would like to tell you something that could save your precious time and money! Best of all, it is free! It's "no". What do you ask? We'll say it again: "No". Sweet and simple "no". Say "no" at your office and see how quickly that pile of work on your desk disappears. "Saying 'no' to others means you are saying 'yes' to yourself, " said Leslie Charles, a professional speaker from East Lansing, Michigan. "Time is precious. People are spending money buying time. And yet we are willing to give up our time because we can't say 'no'." Susie Watson, a famous writer, said people who always say "yes" need to say "no" without guilt or fear of punishment. "I would rather have someone give me a loving 'no' than an obligated 'yes', " she said. Susie Watson says she feels "no" obligation to give an explanation when she says "no" either socially or professionally. Does she feel guilty about it? "Not at all, " said Watson, who is director of advertising and public relations at Timex Corp in Middlebury, Conneticut. "Most people are afraid of saying 'no'... My advice is to say 'yes' only if you don't mean 'no'." Watson said "no" is the most effective weapon against wasting time. "Every year there are more demands on your time... Other people are happy to use up your time, " Watson said. Time saving appears to be "no's" greatest friend. "No" can be your new friend, a powerful tool to take back your life. "No" may even take you further in the business world than "yes". "No" is power and strength. "No" now seems completely correct. "Saying 'no' isn't easy. But finally it's greatly liberating," Charles said. But, he added, a "no" project needs to be worked on every day because it is hard to change long-term habit. But, he also warns: "Don't go to extremes. Don't find yourself saying 'no' to everything. In return you should learn to hear 'no'." Question: When you say "no" to others you should say it in a _ . - secret way - polite way - proud way - guilty way
A: polite way

Q: Read the following article and select the best answer. Article: Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc. In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer. Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer. The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity . While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby , men. These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight. Question: 68. What's Paragraph 2 mainly about? - The study on the life of the overweight. - The study on the relationship between taking exercise and cancer. - The study on the ways of losing weight. - The study on the effects of machine exercise.
A: The study on the relationship between taking exercise and cancer.
