问题     Worried about Internet companies spying on your online browsing? You might turn to something called a virtual private network to protect your privacy. But researchers say these networks can themselves be insecure.
    Earlier this year, the federal government rolled back rules that would have prevented Internet service providers from tracking your activity online. Comcast, AT&T and other providers are now allowed to track and sell your personal data too—with much less fear of regulatory action.
    One solution is a VPN, which is like a dark, secret tunnel you use to go from your computer to a website. While you’re inside the tunnel—clicking on Instagram photos or checking your bank account—third parties can’t see what you’re doing. There are lots of reasons people around the world use VPNs: to hide location, to access work networks, even to avoid government censorship (审查).
    Internet providers handle customer privacy in different ways. Some say you have to opt in for them to sell your data. Because of Internet-connected devices, providers can see more than the websites you browse.
    So, who cares whether Time Warner Cable or Verizon knows when I turn off my lights or whether I stock my fridge with Swiss or cheddar?
    For one thing, those data points can be used to target advertising. And the government or private companies could use the information to deny services, like health insurance—or even water.
    Some VPNs promise anonymous (匿名的) browsing for free or just a few dollars a month; they claim not to share your data. But these services don’t always deliver on their promises. Sometimes the medicine might be worse than the illness. In the first major review of VPN providers, what researchers found was alarming. Nearly 40 percent injected malware (恶意软件).
    Experts suggest researching a VPN before using it and to think of it as a supplementary tool, not a privacy solution. They advise reading the VPN service provider’s privacy policy to see whether it collects or retains any user information that could be traced back to you.
What does the author imply about the users’ data?
选项 A、They may be interpreted to threaten the user’s safety.
B、They may be sold to private companies to make profits.
C、They can be used for the benefit of the government.
D、They can be targeted for public service advertising.
答案C
解析 推理判断题。定位段提到用户数据的用途：这些数据点可以用来定点投放广告；政府或私人公司也可以利用这些信息来拒绝服务，如健康保险，甚至是水。由此推断，政府或私人公司可以看到用户数据，用作拒绝为某些人提供诸如保险一类服务的依据，即数据可以用来让政府受益，故答案为C)。A)“数据被解读以威胁用户安全”，文中未提及此内容，故排除；B)“数据被出售给私人公司以获利”，第四段第二句提到有人说你必须选择让互联网提供商出售你的数据，定位段未提到私人公司，故排除；D)“数据可以用于投放公益广告”，定位段第一句提到这些数据点可以用来定点投放广告，并未特指公益广告，故排除。
