PROBLEM: Article: Do you enjoy seeing the stars twinkling at night ? Or do you love the ocean and sea, diving and racing with lovely dolphins? With heavy burdens on their shoulders, teenagers find it hard to pull out. Even if they are free, they prefer to occupy themselves with computer games or watching TV. How to get children away from screens is a great concern for parents. Now there is some good news for those concerned parents and teachers. A campaign is being launched to encourage children to surrender 30 minutes of screen time a day to head for the great outdoors. The newly formed Wild Network - a collaboration of nearly 400 organizations - is attempting to attract youngsters away from television and computer screen and into fields, woods and parks. Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general well-being. A documentary film, Project Wild Thing, will herald the launch at more than 50 cinemas across the UK from Friday. It looks at the increasingly fragile link between children and nature. Members of the network include the National Trust, RSPB, Play England and the NHS sustainable development unit. Andy Simpson, chairman of the Wild Network, said: "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation. Time spent outdoors is down, roaming ranges have fallen drastically, activity levels are declining and the ability to identify common species has been lost." Suggestions of how to get more time in nature include collecting conkers , camping or snail racing, and observing autumn colour on trees. From January, the network will aim to make suggestions to politicians on how government can do more _ This is not the first time the message of less screen, more play has been brought up. Children in the 1980s were entreated to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off your TV set, and go do something less boring instead".
Question: What is the main purpose of the campaign in UK?
Options: (A) To save 30 minutes for watching TV programme each day. (B) To encourage children to play outdoors. (C) To see the documentary film, Project Wild Thing. (D) To teach students how to learn more efficiently in schools.

SOLUTION: B

PROBLEM: Article: Computer power is moving into the "cloud"--networks of data centres that use the Internet to supply all kinds of services, from e-mail and social networks to data storage and analysis. The rise of cloud computing is rapid and causing huge changes in the tech industry. The old guard is suffering: this week's $67 billion merger between Dell and EMC, makers of computers and storage devices respectively , was a marriage forced by the rise of the cloud. Disruptive newcomers are blooming: if Amazon's cloud-computing unit were a stand-alone public company, it would probably be worth almost as much as Dell and EMC combined. The gains for customers have been equally dramatic. Compared with older IT systems, cloud computing is often much cheaper. It adds tremendous flexibility: firms that need more computing capacity no longer have to spend weeks adding new servers and installing software. In the cloud they can get hold of it in minutes. Their applications can be updated continually, rather than just every few months. Individual users can reach their e-mails, files and photos from any device. And cloud services also tend to be more secure, since providers know better than their customers how to protect their computing systems against hackers. But cloud computing makes one problem worse. In the old IT world, once a firm or a consumer had decided on an operating system or database, it was difficult and costly to switch to another. In the cloud this "lock-in" is even worse. Cloud providers go to great lengths to make it easy to upload data. They accumulate huge amounts of complex information, which cannot easily be moved to an alternative provider. Cloud firms also create a world of interconnected services, software and devices, which is convenient but only for as long as you don't venture outside their universe. Being locked in to a provider is risky. Firms can start to tighten the screws by increasing prices. If a cloud provider goes bust , its customers may have trouble getting back their data. These risks have already caused a debate about whether the cloud needs stricter regulation. Some European politicians want to force cloud providers to ensure that data can be moved between them. That is too heavy-handed, because strict rules will inhibit innovation in what is still a young industry. The history of computing suggests that common standards may well appear naturally in response to customers' demands--just as in personal computers, where it is now much easier to use the same files on different systems. In the meantime, a few commonsense measures can reduce the risk of lock-in. Firms that use more than one cloud provider to host their data are less affected. So are those that keep their most important information in their own data centres. Consumers can take precautions, too. Some services are better than others at enabling users to move data between providers (Google does well on this score). Cloud computing promises its users many benefits, but don't mistake it for some sort of digital heaven.
Question: The author takes "the merger between Dell and EMC" for example to show _ .
Options: (A) the influence of cloud computing on computer and storage device makers (B) the miserable sufferings of old computer companies (C) the rapid development of new computer companies (D) the interaction between old companies and newcomers

SOLUTION: A

PROBLEM: Article: Happiness is _ , researchers reported on Thursday. The more happy people you know, the more likely you are yourself to be happy. And getting connected to happy people improves a person's own happiness. Researchers have been analyzing a collection of facts from tracking sheets dating back to 1971, following births, marriages, deaths, and divorces. Volunteers also listed the information of their closest friends, co-workers, and neighbors. They assessed happiness with a simple, four-question test. "People are asked how often during the past week, one, I enjoyed life, two, I was happy, three, I felt hopeful about the future, and four, I felt that I was just as good as other people," Fowler said. The 60 percent of people who scored highly on all four questions were regarded as happy, while the rest were considered unhappy. People with the most social connections -- friends, spouses , neighbors, s -- were also the happiest, the data showed. "Each additional happy person makes you happier," Christakis said. And happiness is more infectious than unhappiness, they discovered. If a social contact is happy, it increases the possibility that you are happy by 15 percent. A friend of a friend, or the friend of a spouse or a sibling , if they are happy, increases your chances by 10 percent. A happy third-degree friend -- the friend of a friend of a friend -- increases a person's chances of being happy by 6 percent. But every extra unhappy friend increases the possibility that you'll be unhappy by only 7 percent. The finding is interesting and useful. Among other benefits, happiness has been shown to have an important effect on reduced death rate, pain reduction, and improved heart function. So better understanding of how happiness spreads can help us learn how to promote a healthier society. Other data suggested having extra $5,000 increases a person's chances of becoming happier by about 2 percent. A happy friend is worth about $40,000.
Question: According to the research, if you want to be happy, you'd better have more _ .
Options: (A) neighbor communication (B) social connections (C) siblings' support (D) s' relations
