Article: Cities could soon be looking after their citizens all by themselves thanks to an operating system(OS) designed for the metropolis. The Urban OS works just like a PC operating system but keeps buildings 9 traffic and services running smoothly. The software takes in data from sensors dotted around the city to keep an eye on what is happening. In the event of a fire the Urban OS might manage traffic lights so fire engines can reach the blaze swiftly. The idea is for the Urban OS to gather data from sensors buried in buildings and many other places to keep an eye on what is happening in an urban area. The sensors monitor everything from large scale events such as traffic flows across the entire city down to more local phenomena such as temperature sensors inside individual rooms. The OS completely bypasses humans to manage communication between sensors and devices such as traffic lights, air conditioning or water pumps that influence the quality of city life. Channeling all the data coming from these sensors and services into a over-arching control system had lots of benefits, said Steve Lewis, head of Living Plan FT-the company behind Urban OS.The system can help with monitoring patients at hospitals. Urban OS should mean buildings get managed better and gathering the data from lots of sources gives a broader view of key city services such as traffic flows, energy use and water levels. " If you were using an anatomy analogy, the city has a network like the nervous system, talking to a whole bunch of sensors gathering the data and causing actions," said Mr.Lewis. " We distribute that nervous system into the parts of the body--the buildings, the streets and other things. Having one platform managing the entire urban landscape of a city means significant cost savings, implementation consistency, quality and manageability, he added. "And it' s got local computing capacity to allow a building or an automotive platform to interact with people where they are, managing the energy, water, waste, transportation, logistics... Question: If a big city has been equipped with the Urban OS it can _ . Yes or no, is the answer "save a large amount of money"?
No

Article: In many businesses, computers have largely replaced paperwork, because they are fast, and do not make mistakes. And they are honest. Many banks say that their business is "untouched by human hands" and therefore safe. But they have no thought that the growing number of computer crimes show they can be used to steal. Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there is often no proof. A computer cannot remember who used it. It simply does what it is told. The head teller at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from one account to another. Each time a customer whose money he had stolen questioned the balance in his account, the teller said it was a computer mistake, then replaced the missing money from someone else's account. This man was caught at last. Some workers use the computer's power to punish their bosses they consider unfair. Recently, a large company fired its computer record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she stole all the company's computerized records. Most computer criminals have been common workers. Now police wonder if this is "the tip of iceberg". As one official says, "I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing--the ones who really know a computer works." Question: The head teller covered up his crimes _ . Yes or no, is the answer "by moving money through computers"?
No

Article: BEIJING --With a series of measures being adopted to control price rise, the Chinese government is confident of keeping prices at a reasonable level, Premier Wen Jiabao said Sunday morning, asking people to remain confident. "I believe we can keep prices at a reasonable level through our efforts. As a major leader of the government, I have the responsibility and I have the confidence, too." He made the remarks while answering a listener's question during a radio broadcast by China National Radio. Steps taken in the past month, including price controls to curb speculation and monetary tightening , had started to produce results, he said. The government plans to build 10 million units of affordable housing in 2011, up from this year's target of 5.8 million. China will also increase efforts to curb speculation in the housing market, mainly through monetary policies and stricter use of land, Wen said, without giving details. Wen said the country had a good agricultural supply base which gave the government confidence that it could stabilize prices. In a bid to control inflation, the government has also increased the bank reserve requirement ratio six times and lifted interest rate twice this year, he added. Further, authorities have introduced many measures including cutting fees for transportation of agriculture products and controlling food price rise strictly. The overall price level, especially of major consumer goods, has now begun to drop, Wen said. "The fundamental way to stabilize pri ces is to achieve a balance of supply and demand, which requires continuous development of agriculture," said premier, adding that the central government has worked out measures to increase agricultural production. Question: The key to keeping prices at a reasonable level lies in _ . Yes or no, is the answer "achieve a balance of supply and demand"?
