问题     To live in the United States today is to gain an appreciation for Dahrendorf’s assertion that social change exists everywhere. Technology,the application of knowledge for practical ends,is a major source of social change.
    Yet we would do well to remind ourselves that technology is a human creation:it does not exist naturally. A spear or a robot to produce machine parts, neither is much more than a solid mass of matter. For a bird looking for an object on which to rest,a spear or robot serves the purpose equally well. The explosion of the Challenger space shuttle and the Russian nuclear accident at Chernobyl make people see how important the human quality of technology is: they provide cases in which well-planned systems suddenly became completely disordered and there was no ready hand to set them right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use our technology eventually to blow our world and ourselves to pieces. But they have been saying this for decades,and so far we have managed to survive and even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly,the impact of technology on our lives deserves a closer examination.
    Few technological developments have had a greater impact on our lives than the computer revolution. Scientists and engineers have designed specialized machines that can do the tasks that once only people could do. There are those who assert that the switch to an information-based economy is in the same camp as other great historical milestones,particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was a revolution, we find that it was not the machines. The primary reason why it was a revolution is that it led to great social change. It gave rise to mass production and,through mass production, to a society in which wealth was not confined to the few.
    In somewhat similar fashion, computers promise to revolutionize the structure of American life,particularly as they free the human mind and open new possibilities in knowledge and communication. The Industrial Revolution supplemented and replaced the muscles of humans and animals by mechanical methods. The computer emends this development to supplement and replace some aspects of the mind of human beings by electronic methods. It is the capacity of the computer for solving problems and making decisions that represents its greatest potential and poses the greatest difficulties in predicting the impact on society.
A spear or a robot has the quality of technology only when it____.
选项 A、is used both as a cultural and a physical object
B、is utilized by man
C、serves different purposes equally well
D、can be of use to both man and animal
答案B
解析 题目问：只有什么时候，一个矛或一个机器人才是技术?第二段首句“Yet we would do well to remind ourselves that technology is a human creation：it does not exist naturally．A spear or a robot toproduce machine parts．neither is much more than a solid mass of matter．”通过这段话可知，我们最好还是提醒自己，科技是人类的创造，它不存在于自然之中。矛或机器人生产机器零件，这两者都不仅仅是坚实的物体。据此判断，答案是B。
