Article: In a society where lung and breast cancers are leading causes of cancer death worldwide, early detection of the disease is highly desirable. In a new scientific study, researchers present astonishing new evidence that man's best friend, the dog, may have the ability to contribute to early cancer detection. Researchers show scientific evidence that a dog's extraordinary smelling ability can distinguish people with both early and late stage lung and breast cancers from healthy people. Researchers first discovered this in the case report of a dog warning its owner to the presence of a melanoma by constantly sniffing the skin lesion . Later studies published in major medical magazines proved the ability of trained dogs to detect both melanomas and bladder cancers. The new study is the first to test whether dogs can detect cancers only by sniffing the breath of cancer patients. In this study, five household dogs were trained within a short 3-week period to detect lung or breast cancer by sniffing the breath of cancer patients. The experiment consisted of 86 cancer patients (55 with lung cancer and 31 with breast cancer) and 83 healthy people. All cancer patients had recently been diagnosed with cancer and had not yet undergone any chemotherapy treatment . The dogs were presented with breath samples from the cancer patients and the healthy ones, captured in a special tube. Dogs were trained to give a positive identification of a cancer patient by sitting or lying down directly in front of a test station containing a cancer patient sample, while ignoring healthy samples. The results of the study showed that dogs can detect breast and lung cancer between 88% and 97%. Moreover, the study also proved that the trained dogs could even detect the early stages of lung cancer, as well as early breast cancer. The researchers concluded that breath analysis might become a potential of cancer diagnosis. Question: The research found that dogs could help detect cancers by _ . Yes or no, is the answer "sniffing the breath of the cancer patients"?
No

Article: The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. As we know. we're while we're eating; we sit in the car and we sit while we watch TV. And many of us sit for many hours at work. New research shows that sitting less than three hours a day might extend your life by two years. Peter Katzmarzyk,a scientist at the University of Louisiana in the southern United States,says that sitting is ubiquitous in our lives,meaning it is something we do all the time,everywhere. However,Mr. Katzmarzyk says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often,"We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. " Mr. Katzmarzyk and his coi leagues are part of a new generation of researchers studying how sitting all day affects length of life. "Studies that have assessed the relationship between sitting and mortality or television viewing and mortality are very rare. There's only been a few of them,actually five or six now,in the last four or five years. "They found that cutting television time to less than two hours a day could add one-point four years to life. Luckily,change is already coming to some offices,especially in the design of desks. A "standing desk"lets people stand while they work. Another new design is called the "treadmill desk. " A treadmill is an exercise machine that lets you walk in one place. Even some U. S. schools are beginning to experiment with desks that are part bicycle to keep children moving. That's one of the strategies that many companies are using now. Mr. Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives. Question: Why are the desks of all kinds designed for those who sit more? Yes or no, is the answer "To offer them the chance to exercise."?

Yes

Ques: Article: Sabina Castelfrancol Rome October 16, 2011---The U.N. World Food program says there are growing concerns over food insecurity in the developing world. Some of those concerns are discussed in a report to agree with the anniversary Sunday of World Food Day. The theme for World Food Day 2011 is "Food prices-From Crisis to Stability". A ceremony to mark World Food Day will be held Monday at the headquarters of the U.N. Food and Agriculture Organization in Rome. Rising food prices, weather emergencies and political instability are deepening the struggle of families trying to provide for their households in many developing nations. This year's "State of Food In security in the World" report, published last week, focuses on the impact of food price _ confirming that high, unpredictable prices are likely to continue. The report highlighted how poor consumers, small farmers and countries dependent on imports, especially in Africa, have been deeply affected by the food and economic crises. Gregory Barrow is with the World Food Program in Rome. "if you look at the places where World Food program works particularly in developing countries, you see populations of people who might be spending 60,70,80percent of their salaries on purchasing food for their families". Barrow added that if prices become changeful and generally start rising, even by a small amount, it means that many of these people are going to struggle to put nutritious food on their tables. The report also showed that even short-term fluctuations in prices can have a long-term effect on development, and that cutting back on nutritious food in the first 1.000 days of a child's life can affect mental and physical development and finally, future earning capacity . The United Nations has programs in place aimed at reducing the number of hungry people by one-half by 2015.But most observers agree this target is unlikely to be reached. Question: The attitude of Barrow towards food prices is _ . Yes or no, is the answer "concerned"?
Ans: Yes

Article: Smart home applications can share all kinds of helpful information with homeowners. There appears a new housing platform which can detect the stress on electricity -- and the stress on the heart. "There is a growing population of elderly people, and there are statistics to show that more and more of them are going to live alone in the home," said Johann Siau, a senior lecturer at the University of Hertfordshire in the U.K., who was leading the InterHome project. The system was originally designed to provide remote access to a house so owners could be more energy-efficient. In a small type of the system, set-in controller devices connect securely to the Internet. The owner can then monitor them with a cell phone or computer. User feedback helps the system adapt to routines, saving on electricity. While thinking about responding to user behavior and an increasingly elderly population, the researchers decided to add wristband technology that senses important organs of the body such as body temperature and pulse, Siau said. "If someone were to fall, it would detect the fall and it would immediately start the monitor of the pulse to see if the person has gone into shock ," he said. The wristband communicates with the home system wirelessly. Data from the band can be securely transmitted to the home network and accessed by authorized users. "We're working on trying to reduce it to a level where it could potentially be a wrist-sized product," Siau said. But he warned that the technology presented new challenges. "When you start using that on a larger scale, you have issues of privacy or security," he said. Siau said the InterHome home system isn't intended to invade privacy. "We're thinking about the elderly people who are living alone with no one looking after them," he said. "Hopefully this will be able to decrease some concerns and possibly save a few lives." Question: The wristband technology is used in the system to _ . Yes or no, is the answer "sense important organs of a person"?
No
