Article: Even as Google plans to test its fleet of self-driving cars on public roads this summer, its business model remains a bit of a mystery. By 2025, as many as 250,000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm. "Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people," said Chris Urmson, director of Google's self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google's headquarters in Mountain View, California. Previous testing has taken place only on closed courses. The cars are built to operate without a steering wheel, accelerator or brake pedal. "Our software and sensors do all the work," Urmson said. "The vehicles will be very basic -- we want to learn from them and adapt them as quickly as possible -- but they will take you where you want to go at the push of a button." The prototype are the first of a 100-car fleet the tech giant is building. In the long run, Urmson sees a future of safer roads -- the majority of auto accidents are caused by human error -- and fewer traffic jams. Robotic cars could also shuttle people who can't drive because of age or illness. Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don't own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls. The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow "safety drivers" to take control if needed. Google says...

Article: Europe is home to a variety of cultural treasures. Lonely Planet, the world's largest travel guide publisher, has offered pairs of cities for culturehungry but timepoor travelers. London and Paris It takes you about two hours to travel from London to Paris by Eurostar, a high-speed railway service. The two capital cities have been competing in fashion, art and nightlife for decades-but each secretly looks up to the other. No one can doubt the grand and impressive beauty of Paris' Louvre Museum, but if you want to save money, you cannot skip the British Museum free to visit. Compared with London, Paris has more outdoor attractions such as the beautiful green walkway La Promenade Plantee. In Paris, you'll see diners linger over red wine. While in London, you can try some afternoon tea, eat fish and chips or salted cake. Vienna and Bratislava Austrian capital Vienna and Slovakia city Bratislava are an hour apart by train. But since they are linked by the Danube River, the best way to travel is by ship. A tour of the two cities is the perfect way to experience everything from 17th century's Habsburg dynasty splendor to scifi restaurants. Vienna is famous for Mozart and imperial palaces. You can appreciate the perfect blending of architecture and nature in the grand Schonbrunn Palace, and reward yourself with a cup of Vienna coffee, which has made its way to the world's cultural heritage list. Bratislava is best known for its fine dining-the remarkable UFO restaurant. You can enjoy a meatladen dinner here in an amazing setting. Question: Lonely Planet recommends these two pairs of cities because _ . Yes or no, is the answer "they are close but different in many aspects"?
Yes

Article: Do people ever consider the possibility that, if they're exposed to increased reports about a social problem, it's the reporting that has increased rather than the problem? It's increasingly clear that this is the case with school bullying :Only news reports about it have increased, not the behavior itself. In fact, both bullying and fear of it are down among US middle school students The rate of students who reported fearing an attack or harm at school at all has dropped dramatically, from nearly 12% in 1995 to less than 4% in 2011. For black and Hispanic students, it's an even more encouraging shift--from more than 20% of both groups of students worried about being attacked at school to less than 5% in 2011. The decline in actual physical violence in schools is even more dramatic: It was down 74% between 1992 and 2010, according to the latest US Department of Justice data. What about cyberbullying? Online _ increased from 6% in 2000 to 9% in 2005 to 11% in 2010 between, and it's interesting to note that it increased less between 2005 and '10 than in the first 5 years tracked. Because social media is very much a reflection of school social life for young people, the peer aggression seen in social media is a lot like the peer aggression seen on school bathroom walls. So once it finds its "dead level," it will probably decline in the same way verbal and written aggression have. Besides education and crime prevention at the social level, medicine treatment and better access to mental healthcare also contribute to this downward trend in victimization of self and others. The rise of social media is what people don't typically think of as a positive force in society. But Finkelhor, director of the Crimes Against Children Research Center at the University of New Hampshire says, "These technologies might have prevented crime and bullying by providing more ways of help, more forms of social supervision, and interesting activities that destroy forms of alienation that lead to crime". Question: Finkelhor believes that social media have a _ influence on the falling trend of school bullying. Yes or no, is the answer "positive"?
No
