(60) of wealth flowed to these powers which then grew prosperous, (61) the colonies were driven into destitution (贫困). The national economy of colonies was innately defective.

Even their customs were governed by officials from the powers, whose exported goods thus could enter the colonies nearly duty-free. It was after the collapse of colonialist system all over the world that free and fair international trade, at least theoretically, could be possible.

【单选题】By using the phrase "the human quality of technology"(Line 5, Para. 2), the author refers to the fact that technology(). A. has a great impact on human life B. has some characteristics of human nature...
A.
To live in the Untied 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.
B.
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(挑战者号航天飞机) 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(变得混乱)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.
C.
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 informationbased 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 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.
D.
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 poses the greatest difficulties in predicting the impact on society.
