Article: Your smartphone can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a _ side to this smart little equipment of yours----- it might also spread disease. "People are just likely to get sick from their phones as from handles of the bathroom, " Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal. This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms , a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste. Although computers, keys and pens carry germs , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn't played Angry Birds or Fruit Ninja while sitting on the toilet? "Some things that we think are personal are actually more public than we imagine," Cain said. What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don't think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease , an environment that germs really like. So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone's surface: wash your hands regularly. Question: What is the article mainly about? Yes or no, is the answer "Health problems caused by the use of phones"?
Yes

Article: China supports international efforts to secure cyberspace but believes each nation's "Internet sovereignty " must be respected, a top Chinese official said at a cyber security conference on Tuesday. "China, like many other countries, is very concerned about cyber security," said Liu Zhengrong, deputy director general of the Internet Affairs Bureau of the State Council Information Office. "China faces severe cyber security threats," Liu told participants here at the Worldwide Cyber Security Summit, a gathering of government and business leaders from 40 countries hosted by the EastWest Institute think tank. "International cooperation is much needed to safeguard international cyberspace," Liu said. But "Internet sovereignty of each country needs to be respected," the Chinese official added. "Different national and cultural conditions" should be taken into account. Liu declined to answer repeated questions about cyber attacks last year on Google which the Internet giant said originated in China and led to the California company's decision to reroute its searches through Hong Kong. "The Chinese government firmly opposes cyber attacks in any form and Chinese law clearly states that any hackers will be held responsible for their actions," he said. Liu said China itself is a "a major victim of cyber attacks and network viruses" and has laws in place to deal with hackers. "Internet-related crimes (in China) are showing a steady upward trend," Liu said. "We suffer big economic losses from hacking networks and viruses - around $1 billion dollars (6.8 billion yuan) a year." In 2009, Chinese law enforcement authorities investigated about 48,000 cases, a 37 percent increase over 2008, he said. While China has a dynamic Internet population of more than 400 million users and millions of bloggers, there is no "absolute freedom" on the Web, Liu said. "I don't think there is absolute freedom in this world," he said. "When you are speaking via the Internet you must obey laws and respect others' lawful rights." Last Thursday,... Question: What was the top issue of Worldwide Cyber Security Summit? Yes or no, is the answer "To protect digital infrastructure in the world."?
No

Q: Article: surging commodity prices could worsen poverty in many poor countries, the International Monetary Fund warned Tuesday. A new IMF study, seeing the effect of soaring oil and food costs, said many poor and developing countries would likely have to change their economic policies in response to soaring commodity prices. "Some countries are at a dangerous point," warned IMF managing director Dominique Strauss-Kahn. "If food prices rise further and oil prices stay the same, some governments will no longer be able to feed their people and at the same time keep stability in their economies," Strauss-Kahn said. The IMF chief called for a "broad cooperative approach" to help handle higher oil and food prices, and said the IMF stood ready to assist countries in need. Strauss-Kahn said the international community would also have to play a role in helping to reduce the effect of commodity price shocks which have caused protests in some countries. European truckers have blockaded major roads to protest fuel prices in recent weeks and food riots have occurred in Cameroon, Bangladesh, and Somalia among other countries in recent months. "Poor countries that are highly dependent on food imports are particularly vulnerable to rising food prices," the IMF report said. Anti-poverty campaigners are concerned that rising commodity costs could roll back advances made through anti-poverty campaigns in recent years, particularly because poorer families tend to spend much more of their household income on food. The IMF report found that poor households are most affected by food price inflation and "warned that the share of undernourished people in developing countries could rise rapidly above the current 40 percent of total population". Energy and food values are still rising and the IMF said its research suggests "the problem is worsening". The Washington-based fund said it is working closely with its member countries to help reduce inflationary pressures taking into account countries' specific needs. The report said that... Question: To reduce the effects of rising oil and food prices, the IMF suggests _ . Yes or no, is the answer "taking different measures to cooperate with its member countries"?
A: No

Article: Well, more and more companies are beginning to create products and services for teenagers. The Disney Company sells the Hannah Montans television show, music, film and merchandise to teenagers and their parents. You can get everything from branded lunchboxes and mobile phone covers, to monthly fan magazines and clothing. The High School Musical series of films is also intended for a teenage audience. So, it's all about sales, which tells us teenagers must have more money, freedom and influence upon their parents than they've ever had before. UK teenagers never used to be worried about spending money on clothes and fashion accessories . That's changed. Now, they are much more fashion conscious and concerned about their image. In a world of television programmes that promise overnight success and fame at a young age (for example, the shows Britain's Got Talent and American Idol), some people think it's extremely important to look fashionable. So what does teenage fashion look like? Well, it's quite horrible really, but then I'm a bit too old to appreciate it, I suppose. It's lots of brightly coloured materials, particularly pink, and usually plain, not patterned. There are plenty of bows, necklaces and bracelets , too. It's all very cute , if that's your taste. Surely none of the above is a good thing, is it? Can it really be healthy for us to encourage kids to be like adults at such a young age? Are we stealing childhoods in return for a bit of profit? Well, the UK government is certainly concerned, and for that reason has strict laws preventing companies from explicitly marketing their products and services at children. Even the rest of UK society is concerned. Now that people are aware of the problem, there is a popular backlash against the exploitation of children by commercial marketing. Question: It can be inferred from the passage that the teenagers nowadays _ . Yes or no, is the answer "often ask their parents to buy things for them"?
No
