Happiness is _ , researchers reported on Thursday. The more happy people you know, the more likely you are yourself to be happy. And getting connected to happy people improves a person's own happiness. Researchers have been analyzing a collection of facts from tracking sheets dating back to 1971, following births, marriages, deaths, and divorces. Volunteers also listed the information of their closest friends, co-workers, and neighbors. They assessed happiness with a simple, four-question test. "People are asked how often during the past week, one, I enjoyed life, two, I was happy, three, I felt hopeful about the future, and four, I felt that I was just as good as other people," Fowler said. The 60 percent of people who scored highly on all four questions were regarded as happy, while the rest were considered unhappy. People with the most social connections -- friends, spouses , neighbors, s -- were also the happiest, the data showed. "Each additional happy person makes you happier," Christakis said. And happiness is more infectious than unhappiness, they discovered. If a social contact is happy, it increases the possibility that you are happy by 15 percent. A friend of a friend, or the friend of a spouse or a sibling , if they are happy, increases your chances by 10 percent. A happy third-degree friend -- the friend of a friend of a friend -- increases a person's chances of being happy by 6 percent. But every extra unhappy friend increases the possibility that you'll be unhappy by only 7 percent. The finding is interesting and useful. Among other benefits, happiness has been shown to have an important effect on reduced death rate, pain reduction, and improved heart function. So better understanding of how happiness spreads can help us learn how to promote a healthier society. Other data suggested having extra $5,000 increases a person's chances of becoming happier by about 2 percent. A happy friend is worth about $40,000. The finding of the research mainly shows _ . A) happiness can always be bought with money. B) a happy friend is worth more than a happy spouse C) the spread of happiness can lead to a healthier society D) happiness can cure most of the terrible diseases

Q: As we know, it is very important that a firm should pay attention to the training of its staff as there exist many weak points in its various departments. Staff training must have a purpose, which I defined when a firm considers its training needs, which are in turn based on job descriptions and job specifications. A job description should give details of the performance that is required for a particular job, and a job specification should give information about the behaviour, knowledge and skills that are expected of an employee who works in it. When all of this has been collected, it is possible to make a training specification. This specifies that the training department must teach for the successful performance of the job, and also the best methods to use in the training period. There are many different training methods, and there are advantages and disadvantages of all of them. Successful training performances depend on an understanding of the difference between learning about skills and training in using them. It is frequently said that learning about skills takes place "off the job" in classroom, but training in using these skills takes place "on the job," by means of such activities as practice in the workshop. It's always difficult to evaluate the costs of a training programme. The success of such a programme depends not only on the methods used but also on the quality of the staff who do the training. The evaluation of management training is much more complex than that. From the passage we know the success of a training programme lies in_. A) the training methods and the quality of the training staff B) the performance of the trainees in the programme C) the places where the training programmes take place D) the way to evaluate the training programme
A: A
