问题     To live in the United States today is to gain an appreciation for Dahrendorf’s assertion(主张)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 is as much a cultural as a physical object. Until humans use a spear to hunt game 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(航天飞机)and the Russian nuclear accident at Chernobyl drive home the human quality of technology; they provide cases in which well-planned systems suddenly went haywire(失去控制的)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 out 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(声称) that the switch to an information-based economy is in the same camp as other great historical milestones(里程碑), 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 revolutionary 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 extends 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 that peels the greatest difficulties in predicting the impact on society.
The examples of the Challenger and Chernobyl cited by the author serve to show that______.
选项 A、if not given close examination, ,technology could be used to destroy our world
B、technology is a human creation, so we are responsible for it
C、technology usually goes wrong, if not controlled by man
D、being a human creation, technology is liable to error
答案B
解析 细节题。本题问的是：作者引用的挑战者号航天飞机和切尔诺贝利核电站的例子是为了说明______。根据第2段第6句“Since technology is a human creation，we are responsible for what is done with it”可知，既然技术是人类创造的，我们也就该为它负责，故选B 。
