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: Smith-Spangler and her colleagues found that _ . Options: A: organic food could reduce the risk of heart disease B: traditional food was grown with more natural methods C: both organic and traditional food they examined were safe D: there was not a presence of any forms of bacteria in organic food

Article: Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood. Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear. This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert. Question: Which title best fits the passage? Options: A: Trees and Man B: The Function of Tree Wood C: How do People do with Trees? D: The Usage of Tree Roots

What makes these place an almost universal attraction? What makes foreign kings and queens and other important people want to visit these Disney parks?

All new employees, from vice presidents to part-time workers, begin their employment by attending Disney University and taking "Traditions I". Here, they learn about the company's history, how it is managed, and why it is successful. They are shown how each department relates to the whole. All employees are shown how their part is important in making the park a success. After passing "Traditions I", the employees go on to do more specialized training for their specific jobs. No detail is missed. A simple job like taking tickets requires four eight-hour days of training. When one ticket taker was asked why it took so much training for such a simple, ordinary job, he replied, "What happens if someone wants to know where the restrooms are, when the parade starts or what bus to take back to the campgrounds?...We need to know the answers or where to get them quickly. Our constant aim is to help our guests enjoy the party." Even Disney's managers get involved in the daily management of the park. Every year, the mangers leave their desks and business suits and put on special service clothes. For a full week, the bosses sell hot dogs or ice cream, take tickets or drive the monorail , and take up any of the 100 jobs that make the entertainment park come alive. The managers agree that this week help them to see the company's goals more clearly. All these efforts to serve the public well have made Walt Disney Productions famous. Disney is considered by many as the best mass service provider in Americaor the world. As one longtime business observer... Question: This passage is mainly about_. Options: A: how Disney employees are trained B: the history and traditions of the Disney enterprises C: why Disney enterprises make a lot of money D: the importance Disney place on serving people well
