Of the 54 big cities studied by the World Health Organization and the United Nations, Milan is considered to have the worst air pollution. According to these two10-year studies, the level of air pollution in Milan is twice as high as the levels in Paris and Beijing and three times those in Tokyo and London, and four times that in New York. The reason for Milan's bad pollution, to some experts, is that the city lies in a valley that holds back the poisonous gases. Though Milan has taken some measures to lower the level of pollution, the situation is still worrying. People joke to each other, "If you are traveling to Milan, be sure to bring your gas mask."

Q: Read the following article and select the best answer. Article: Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. "Our suggestion is for people to increase their intake, through diet or a vitamin supplement," Dr. Cedric Garland said in a telephone interview. Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. "There's nothing that has this ability to prevent cancer," he said, urging governments and public health officials to do more to fortify foods with vitamin D.Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units (IU) a serving. People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day, Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences. The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine. African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake, the authors said. Question: Which of the following food can lower people's chance of getting cancer? - Fortified orange juice - Milk - Fortified yogurt - All of the above
A: All of the above

Question: Read the following article and select the best answer. Article: Chelsea Bourque was 17 years old. When she took a summer job, her mother, Kim Guidry, was confident her daughter would get good life experience. And Chelsea wanted to make her own money and be more independent. Kim didn't worry about her daughter because she'd known the store owner for years. Chelsea did such a good job that when summer ended she was asked to stay on and even open and close the shop sometimes. That was when Kim started feeling uneasy. "She'd be there alone with a drawer full of money for the first or last 20 minutes of her shift ," says Kim. "If she was opening, I'd drop her off to lock the door the minute she got into the building, and I'd wait in the car until the owner arrived. If she was closing, I'd arrive 20 minutes early. You can never be too careful." Kim's concerns were natural. Even though the 6 million American teens who hold job benefit a lot -- learning to manage money, developing time-management skills, and becoming good at problem-solving with other people -- they face some dangers as well. About 230 000 teen workers are injured yearly, from burns and cuts in restaurant kitchens to falls from roofs on buildings. Deaths, fortunately, are rare, but they do happen -- between 60 and 70 each year, according to the National Institute for Occupational Safety and Health. But for most teens and their parents, the pay-offs of working do more good than harm. So help your teens get most out of employment with these stay-safe tips. Question: The passage is developed mainly by _ . - giving a specific example - providing an idea by reasoning - testing an idea by reasoning - asking and answering questions
Answer: giving a specific example

Read the following article and select the best answer. Article: Polar bears are born in dens on land and their mother stays with them for the whole winter without eating anything. The mother and the babies come out from the dens around March, _ from a long winter and must immediately go hunting to find food to stay alive. Now, the only hunting they know is to catch seals from floating ice in the open ocean. In March, polar bear mothers and babies have to swim from the land in Spitsbergen to the edge of the polar ice cap. Normally this is a short swim, since in March the polar ice cap is very close to the land, and the polar bears, and even the babies, are good swimmers. However, last year we saw that the polar ice cap had become smaller in size due to global warming. Swimming hundreds of miles, especially when they are hungry and have babies following them, is really hard, and many bears are dying because of starvation. The polar bear population in the Spitsbergen area was once threatened by hunters. In the 1970s, a ban on hunting was imposed and the polar bear population has been steadily increasing from just a few hundred to about 2,000 to 3,000. This was a great success story. However, now, because of global warming, the population is again in danger. If we do not stop making so much carbon dioxide, we will lose these beautiful animals forever. The polar bears are just one example of animals that have become endangered because of man's appetite for energy obtained by burning fossil fuels. All life on earth could be in danger unless we change our ways. What can we do? To reduce the amount of carbon dioxide in the air we must save and make energy without burning coal and oil. Instead, we can use the sun or the wind to generate electricity. We must also cut down on needless driving and turn off things that use electricity when we are not using them. In addition, we have to stop cutting down forests and start planting more trees. Question: Why do the bears swim to the edge of the polar ice cap? - To get back to the ocean. - To catch seals for food. - To get to a colder place. - To teach their children how to swim.
To catch seals for food.
