Read the following article and select the best answer. Article: Is It Worth Buying Organic Food? Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels . However, if you think paying a little more for organic food gets you a more nutritious and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren't necessarily more nutritious, and they're no less likely to suffer from disease-causing bacteria, either. The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. "We did not find strong evidence that organic food is more nutritious or healthier," says Dr. Crystal Smith-Spangler from Stanford. "So consumers shouldn't assume that one type of food has a lower risk or is safer." For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats. While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends. Organic food is produced with fewer chemicals and more natural-growing practices, but... Question: The new research questions whether organic food _ . - should replace traditional food - has been overpriced by farmers - is grown with less harmful chemicals - is really more nutritious and healthier
is really more nutritious and healthier

Read the following article and select the best answer. Article: Arthur Miller (1915--2005) is universally recognized as one of the greatest dramatists of the 20th century. Miller's father had moved to the USA from Austria-Hungary, drawn like so many others by the "Great American Dream". However, he experienced severe financial hardship when his family business was ruined in the Great Depression of the early 1930s. Miller's most famous play,Death of a Salesman,is a powerful attack on the American system, with its aggressive way of doing business and its insistence on money and social status as indicators of worth. In Willy Loman, the hero of the play, we see a man who has got into trouble with this system. Willy is "burnt out" and in the cruel world of business there is no room for sentiment: if he can't do the work, then he is no good to his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at a loss as to what to do with his lack of success. He refuses to face the fact that he has failed and kills himself in the end. When it was first staged in 1949, the play was greeted with enthusiastic reviews, and it won the Tony Award for Best Play, the New York Drama Critics' Circle Award, and the Pulitzer Prize for Drama. It was the first play to win all three of these major awards. Miller died of heart failure at his home in Roxbury, Connecticut, on the evening of February 10, 2005, the 56th anniversary of the first performance ofDeath of a Salesmanon Broadway. Question: After it was first staged,Death of a Salesman _ . - achieved huge success - won the first Tony Award - was warmly welcomed by salesmen - was severely attacked by dramatists
achieved huge success

Q: Read the following article and select the best answer. Article: Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a physical object.This is now possible with the help of 3D printers.Such machines were once used just by universities and big companies.But now, stores with 3D printing services are appearing around the United States. Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago.The store is filled with tools like a laser cutter, an industrial sewing machine and 3D printers.Bryan Jaycox requires $ 15 an hour to print an object.He also charges a fee depending on the size of the object and up to $ 50 an hour for design and labor services. The Jaycoxs also offer 3D printing classes for anyone who is interested.One of the students in a recent class was Ki Chong Tran.He plans to open a 3D printing business in Cambodia."The demand has been amazing.It's been much more than I would have imagined," said Ki Chong Tran. "I think 3D printing is going to be huge. It's going to make a huge impact on society as a whole," he added. Mr Jaycox predicts that within five years, 3D printing technology could become more consumer friendly. But Ki Chong Tran says even current technology can make a difference in a developing country like Cambodia."With 3D printing you can give them tools, and you put it in their hands so they are responsible more for their own development. They learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank.You can actually create things that give value to the world," said Ki Chong Tran. He says it's not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality. Question: In Mr Jaycox's opinion, within five years 3D printing will _ . - make it easier to do business - be accessible to all consumers - change the way of social contact - bring about more profits to the sellers
