问题     The car has reshaped our cities. It seems to offer autonomy for everyone. There is something almost delightful in the detachment from reality of advertisements showing mass-produced cars marketed as symbols of individuality and of freedom when most of their lives will be spent making short journeys on choked roads.
    For all the fuss made about top speeds, cornering ability and acceleration, the most useful gadgets on a modern car are those which work when you’re going very slowly: parking sensors, sound systems, and navigation apps which will show a way around upcoming traffic jams. This seems to be one of the few areas where the benefit of sharing personal information comes straight back to the sharer: because these apps know where almost all the users are, and how fast they are moving almost all the time, they can spot traffic congestion (堵塞) very quickly and suggest ways round it.
    The problem comes when everyone is using a navigation app which tells them to avoid everyone else using the same gadget. Traffic jams often appear where no one has enough information to avoid them. When a lucky few have access to the knowledge, they will benefit greatly. But when everyone has perfect information, traffic jams simply spread onto the side roads that seem to offer a way round them.
    This new congestion teaches us two things. The first is that the promises of technology will never be realised as fully as we hope; they will be limited by their unforeseen and unintended consequences. Sitting in a more comfortable car in a different traffic jam is pleasant but hardly the liberation that once seemed to be promised. The second is that self-organisation will not get us where we want to go. The efforts of millions of drivers to get ahead do not miraculously produce a situation in which everyone does better than before, but one in which almost everyone does rather worse. Central control and collective organisation can produce smoother and fairer outcomes, though even that much is never guaranteed.
    Similar limits can be foreseen for the much greater advances promised by self-driving cars. Last week, one operated by the taxi company Uber struck and killed a woman pushing her bicycle across a wide road in Arizona. This was the first recorded death involving a car which was supposed to be fully autonomous. Experts have said that it suggests a "catastrophic failure" of technology.
    Increasingly, even Silicon Valley has to acknowledge the costs of the intoxicating (令人陶醉的) hurry that characterises its culture. What traffic teaches us is that reckless and uncontrolled change is as likely to harm us as it is to benefit us, and that thoughtful regulation is necessary for a better future.
What does the author say about technology?
选项 A、Its consequences are usually difficult to assess.
B、It seldom delivers all the benefits as promised.
C、It depends on the required knowledge for application.
D、Its benefits are guaranteed by collective wisdom.
答案B
解析 由题干中的technology定位至第四段第二句。事实细节题。作者在第四段第二句指出，技术承诺的好处永远不会像所希望的那样完全实现；它们将被不可预见和意想不到的后果所限制，说明技术很难兑现它所承诺的一切好处，故答案为B)。根据文章第四段第五、六句，作者认为技术产生的结果很难保证，并不是难以评估，故排除A)；文中第三段提到，少数幸运儿若能获取这些信息，将受益良多，并未提到应用程序所需要的知识，故排除C)；文章第四段第六句提到，通过中央控制和集体组织可以产生更平稳、更公平的结果，但即便是这种结果，也从来无法得到保证，故排除D)。
