Article: Acting is such an over-crowded profession that the only advice that should be given to a young person thinking of going on the stage is "Don't!". But it is useless to try to discourage someone who feels that he must act, though the chances of his becoming famous are slim. The normal way to begin is to go to a drama school. Usually only students who show promise and talent are accepted, and the course lasts two years. Then the young actor or actress takes up work with a repertory company, usually as an assistant stage manager. This means doing everything that there is to do in the theatre: painting scenery, looking after the furniture, taking care of the costumes, and even acting in very small parts. It is very hard work indeed. The hours are long and the salary is tiny. But young actors with the stage in their blood are happy, waiting for the chances of working with a better company, or perhaps in films or television. Of course, some people have unusual chances which lead to fame and success without this long and dull training. Connie Pratt, for example, was just an ordinary girl working in a bicycle factory. A film producer happened to catch sight of her one morning waiting at a bus stop, as he drove past in his big car. He told the driver to stop, and he got out to speak to the girl. He asked her if she would like to go to the film studio to do a test, and at first she thought he was joking. Then she got angry and said she would call the police. It took the producer twenty minutes to tell Connie that he was serious. Then an appointment was made for her to go to the studio the next day. The test was successful. They gave her some necessary lessons and within a few weeks she was playing the leading part opposite one of the most famous actors of the day. Of Course, she was given a more dramatic name, which is now world-famous. But chances like this happen once in a blue moon! Question: According to the passage, the main reason why young people should be discouraged from becoming actors is _ . - actors are very unusual people - the course at the drama school lasts two years - acting is really a hard job - there are already too many actors
there are already too many actors

During the middle German Prime Minister Otto Von Bismarck may be most famous for his military and diplomatic of the 19th century, Germany, along with other European nations, experienced an unprecedented rash of workplace deaths and accidents as a result of growing industrialization. Motivated in part by Christian sympathy for the helpless as well as a practical political impulse to get the support of the socialist labor movement, Chancellor Bismarck created the world's first workers' compensation law in 1884. By 1908, the United States was the only industrial nation in the world that lacked workers' compensation insurance. America's injured workers could sue for damages in a court of law, but they still faced a number of tough legal barriers. For example, employees had to prove that their injuries directly resulted from employer negligence and that they themselves were ignorant about potential hazards in the workplace. The first state workers' compensation law in this country passed in 1911, and the program soon spread throughout the nation. After World War II, benefit payments to American workers did not keep up with the cost of living. In fact, real benefit levels were lower in the 1970s than they were in the 1940s, and in most states the maximum benefit was below the poverty level for a family of four. In 1970, President Richard Nixon set up a national commission to study the problems of workers' compensation. Two years later, the commission issued 19 key recommendations, including one that called for increasing compensation benefit levels to 100 percent of the states' average weekly wages. In fact, the average compensation benefit in America has climbed from 55 percent of the states' average weekly wages in 1972 to 97 percent today. But, as most studies show, every 10 percent increase in compensation benefits results in a 5 per cent increase in the numbers of workers who file for claims. And with so much more money... Question: Why was it hard for the American injured workers to get compensation in the early 20th century? - had totally different compensation programs. - Different states in the U.S. - America's average compensation benefit was much lower than the cost of living. - They have to present evidence that theirs bosses were responsible for the accidents.
They have to present evidence that theirs bosses were responsible for the accidents.

Read the following article and select the best answer. Article: Technology is making life easier for some dairy farmers.They use robotic systems to milk their cows.Cows are trained to follow a series of paths that lead to milking stations.Only one cow at a time can enter a station. Once inside,the cow is rewarded with food.As the cow eats,a robotic arm cleans and connects the animal to the milking machine.A few minutes later,milking is complete.The gate is opened,the cow is released and the next cow enters. The robotic systems are designed to operate 24 hours a day.The cows get to decide when they want to be milked.Cows are milked an average of about three times a day.Some are milked four to six times a day. The cows wear collars around their necks that identify them to the system.A computer keeps records on their eating and milking.A cow is released from the station if the computer decides it should not be milked. The automated system also measures the temperature and color of freshly produced milk.Milk is thrown away if it does not pass the tests. Professor Plaut believes the systems will appeal especially to the next generation of farmers.She means young people who are more interested in technology and less interested in working all the time on the farm.Still,she says the price of robotic milking systems will continue to limit their use. Doug and Tina Suhr have more than 100 cows on their family farm.Last year it became the fourth farm in southeast Minnesota to get a robotic milking system.A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars.The second cost 150 000. Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot.He says the increase in milk production reaches a high of more than six kilograms per cow per day. Question: Why is the robotic system not popular now? - Because young people have no interest in it. - Because it is difficult to learn how to use it. - Because people can't afford to buy it. - Because it usually causes the waste of milk.
(A).
Because people can't afford to buy it.
