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: Article: Robots industry is developing so rapidly that there is no denying that we may one day find ourselves surrounded by robots. The humanoid (human like) robots with two legs such as Honda Motor Co. Ltd's ASIMO would likely have an easier time climbing up stairs inside homes than a robot that moves on wheels, developers say. But it will be some time before such devices make their way into people's homes. "They may look smart, but they are still quite stupid," Shimoyama said. "I don't think they will ever be as smart as humans." While safety is an obvious concern, robots also need to be sensitive to people's needs. Researchers at Fujitsu Frontech Ltd and Fujitsu Laboratories responsible for developing "Enon", a guide and patrol robot designed for use in shopping malls and corporate facilities , are working on this. Enon, which has a humanoid upper body but no legs, is equipped with a touch screen on its chest and space in its stomach to carry loads weighting up to 10 kg. In guide mode, it will check a newcomer and approach the person with a nod and a greeting: "Are you a visitor? Hello." Visitors requiring directions can point to icons displayed on Enon's chest screen. If the restroom icon is pressed, the screen will display a map that shows the way. The robot will then face and point in the direction of the restroom, although it won't actually walk the visitor there. Enon is now in use at four locations in Japan, including a shopping mall near Tokyo. The main goal is to make it more helpful for the elderly. "People who work in the transportation sector often ask whether we can build a robot that will find elderly people who look lost in train stations, and ask them if they are all right," said Toshihido Marita, director of Fujitsu Laboratories Ltd's autonomous system laboratory. "Actually that is hard to do, very hard," he said.
Question: The advantage of Honda Motor Co. Ltd's ASIMO is that _ .
Options: (A) it can do any housework for us (B) it can talk with patients or old people (C) it can climb up stairs as humans (D) it can walk smoothly with its wheels
Asnwer: C

Answer: Yes

Question: Article: WASHINGTON -- Patients with HIV, the virus that causes AIDS, often develop vitamin deficiencies . A new study has found that giving these patients a multivitamin with a mineral supplement helps to fight the disease and slows the disease's progression. Sub-Saharan Africa has always been the center of the AIDS. In Botswana, despite aggressive prevention campaigns, one out of every four adults is infected with HIV. Professor Marianna Baum based her latest research there. Baum recruited almost 900 newly infected adults who had not yet received the anti-AIDS drugs that target the virus. These adults were then divided into groups that randomly received different combinations of vitamins B, C and E, the mineral selenium or a placebo . Most patients with HIV become deficient in these vitamins, which help improve immunity . Baum said she initially thought the multivitamins alone or selenium alone would be effective in strengthening the immune system, but found that incorrect. "We were surprised to find that only the combination was effective," said Baum. Research shows that when people with HIV receive anti-retroviral drugs shortly after infection, they can remain healthy and are less likely to pass the virus to others. For many countries, however, the cost of these anti-AIDS drugs is still prohibitive. Baum said the vitamin and mineral combination treatment should help low income countries better control the virus. "A simple multivitamin supplementation with selenium provided early in HIV disease can actually slow the HIV disease progression and it is safe. It is low cost and it should be provided very early in HIV infection," said Baum. Baum said the supplements are not meant to replace anti-retroviral therapy, but can help those who cannot obtain the drugs. Dr. Anthony Fauci, a world famous expert on AIDS, disagrees. "I haven't read the paper, but having taken care of HIV-infected individuals for three decades, I would doubt that vitamins are going to have a major effect on stopping the virus," said Fauci. Fauci said vitamin and mineral supplements may make a patient generally healthier, but the only thing that truly works to stop HIV is anti-retroviral treatment. Baum's study was published in the Journal of the American Medical Association.
