Question: Article: Farming is moving indoors, where the sun never shines, where rainfall is irrelevant and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature, wetness, air quality and nutrition. It could be in a New York high-rise or a sprawling complex in the Saudi desert. It may be an answer to the world's food problems. The world is already having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those--about 3 billion--are hungry or ill-fed. Food prices, currently increasing, are _ by dryness, floods and the cost of energy required to plant, harvest and transport. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world are already using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6. 8 billion to 9 billion. To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to completely increase crop output. Gertjan Meeuws has taken the concept of a greenhouse a step further, growing vegetables and house plants in enclosed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating similar day and night, but according to the rhythm of the plant. A building of 100 square meters and 14 layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch, about 140, 000 people. Their idea is not to grow foods that require much space, like corn or potatoes. Here sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoors agriculture. And city farming means producing food near the consumer, and there's no need to transport it long distances.
Question: It can be inferred from the text that Gertjan Meeuws's farming _ .
Options: (A) helps save sea water a lot (B) suits different conditions (C) is completely different from greenhouse agriculture (D) suits the production of corn
Asnwer: B

Answer: Yes

Question: Article: Google is preparing for changes in its privacy policy beginning March 1st. The company says it plans to replace more than 60 separate policies for different products with one main policy. Privacy activists criticized last month's announcement. They are concerned that the new policy will make it easier to track the activities of users across Google's many products -- from Gmail to YouTube. Marc Rotenberg heads the Electronic Privacy Information Center in Washington. He says Google's aim is to create a single unified profile of its users. "We believe that not only is that a threat to privacy, we actually believe it is illegal, because last year Google entered into an agreement with the US Federal Trade Commission in which they said they would not engage in that kind of data sharing without the permission of their users." Google says its new policy will make it simpler for users to share information across services like Google Search, Gmail and Google Calendar. And it says the new policy will help personalize each user's experience. Over time, it says, users can expect to see better search results, fewer unwanted advertisements and more content targeted to their interests. But Marc Rotenberg says in return, people who choose to use Google will lose control over the information they share. "The type of information you might provide for an e-mail service, for example, such as your address book, which contains private information, is different from the type of information that you might provide for a social network service where people purposely make information publicly available to their friends." Mr. Rotenberg says these two kinds of services should be kept separate. "By trying to combine these two services, in our view, Google is actually undermining a very well established expectation of privacy, especially for popular Internet services like electronic mail." Critics also see a bigger problem with Google's new policy. The plan would not give users a choice to drop out of the data sharing. "In our view, if people want to make their potential information available, they certainly should have the right to do that. What we are objecting to is the effort by the company to take away from the users that choice that they should have. That just seems unfair." Google says it will not be collecting any more data than it does now. And it says users will still be able to control many privacy settings. For example, they can disable their search history and set Gmail chat to "off the record." European Union officials have asked the company to delay the new policy to make sure it would not violate any EU data protection laws. Marc Rotenberg thinks the Federal Trade Commission in Washington might also try to block the new policy.
Question: What's Google's purpose to change its privacy policy according to Marc Rotenberg?
Options: (A) To serve its users better. (B) To make it easier for their work (C) To personalize each user's experience (D) To build up a unified profile of its users
Asnwer: B

Answer: No

Question: Article: Millions of American kids come home to or leave an empty house every day. However, parents are increasingly using an existing technology -- home security systems -- to keep an eye on their "home-alone" children. In the early days of home security, the systems were basically designed just to keep the bad guys out. Now, many parents are also using them to make their children safe when they are at home alone. Below are some simple rules for adults to teach their children: Every child should memorize his or her own full name and address, and home, work and cellphone numbers of each parent. Also keep this information posted next to the phone at home. If your child is too young to memorize the information, he or she may be too young to be home alone -- for any time. Teach your child to observe things around him or her when he or she returns to the house. If a door or window is slightly open, the child has any reason to suspect someone has been in the house that shouldn't be, have him or her call you, then wait at a safe house a neighbor offers. Warn your child never to answer the doorbell or telephone when they are home alone. Besides, set a rule that he or she must never play outside the house when no one else is at home. Be sure he or she knows how to disarm and arm your home security system. Program your control panel to give you a message when your child enters or leaves the house, and arms or disarms the system. If your child forgets to rearm the system, you can call him or her with a personal reminder.
