I'm taking a test and have to guess the right answer to the question after the article. Article: Recently a friend of mine wrote to me about her experience in Holland: A very old man asked me to come to his apartment, and he would donate a bike to the project. I went over to get it, and it was half a bike, which was locked to a pole and had obviously been there for years. The temperature was well below zero. It became clear that he was in fact super-lonely, and torn between usual Dutch distrust of strangers and desperation for human contact. He finally begged me to come up to his apartment (where he obviously lived alone). You may know that Dutch people are the tallest in the world, reflecting a very high standard of living. But -- if this old man is not unusual -- reducing the loneliness of old people isn't part of the Dutch social contact, admirable as _ may be. I recently watched the Frontline program Sick Around the World. It suggested that the old man isn't unusual. In England, where doctor visits are free, a doctor said he has several patients who come weekly, purely because they're lonely. In Japan, some patients have their blood pressure measured very often -- most probably for the same reason. In Taiwan, if you see a doctor 20 times in one month, someone from the government will come to talk to you. Not about loneliness -- about overuse of medical care. The Frontline program made nothing of any of these facts, which were included to show that access was easy. Really the idea that everyone needs human contact isn't mysterious or controversial. My explanation is there's a double blow: Not only do lonely old people have little power, it's also clear that their problem (loneliness) isn't caused by a "chemical imbalance". So no drugs can be sold to treat it. And there's no diagnostic category. When these lonely old people use what little power they have by visiting their doctor, the doctor -- I'm assuming -- doesn't do anything to get rid of the loneliness. Even if you visit 20 times in a month. Question: The tone of the author is _ . Options: A: skeptical B: critical C: positive D: concerned

I'm taking a test and have to guess the right answer to the question after the article. Article: Photographs are everywhere. They decorate the walls of homes and are used in stores for sales of different goods. The news is filled with pictures of fires, floods, and special events. Photos record the beauties of nature. _ can also bring things close that are far away. Through photos, people can see wild animals, cities in foreign lands, and even the stars in outer space. Photos also tell stories. Reporting the news through photos is called photojournalism. At times photojournalists tell their stories through a single picture. At other times, they use a group of pictures to tell a story. Each picture is like a chapter in a book, which can do more than record the facts. It can also be a strong force for social change. Jacob Riis was among the first photojournalists. He took pictures of parts of New York City where the poor lived. Riis believed that poverty caused crime, and he used photos to help him prove his point. A few years later, the photos of small children working in factories by Lewis Hine shocked the public. Hine's pictures helped bring about laws to protect such children. Hundreds of pictures may have to be taken in order to get one or two really good photos. It takes science to have the photo come out clearly and art to make a photo that has a good design and expresses feeling. Photojournalists make an actual record of what they see. A photo, however, can be both a work of art and an actual record. It can record an important event as a beautiful or exciting picture. As historical and artistic documents,photos can become more important over time. Today photojournalists still have their pictures appear in newspapers and magazines. They also publish them in books and on the Internet. Question: The photos of the small children by Hine show us that photos _ . Options: A: are also works of art B: are popular ways of reporting news C: often shock the public D: can serve as a force for social change

I'm taking a test and have to guess the right answer to the question after the article. 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: What is the author's attitude toward organic food? Options: A: Sceptical. B: Neutral. C: Unconcerned. D: Approving.
