问题 根据以下材料，回答题To live in the United States today is togain an appreciation for Dahrendorf′s assertion that social change existseverywhere. Technology, the application of knowledge for practical ends, is a majorsource of social change.Yet we would do well to remind ourselvesthat technology is a human creation; it does not exist naturally. A spear or arobot is as much a cultural as a physical object. Until humans use a spear to huntgame or a robot to produce machine parts, neither is much more than a solid massof matter. For a bird looking for an object on which to rest, a spear or robotserves the purpose equally well. The explosion of the Challenger space shuttleand the Russian nuclear accident at Chemobyl drive home the human quality oftechnology; they provide cases in which well-planned systems suddenly wenthaywire and there was no ready hand to set them right. Since technology is ahuman creation, we are responsible for what is done with it. Pessimists worrythat we will use our technology eventually to blow our world and ourselves topieces. But they have been saying this for decades, and so far we have managedto survive and even flourish. Whether we will continue to do so in the yearsahead remains uncertain. Clearly, the impact of technology on our livesdeserves a closer examination.Few technological developments have had agreater impact on our lives than the computer revolution. Scientists andengineers have designed specialized machines that can do the tasks that onceonly people could do. There are those who assert that the switch to aninformation-based economy is in the same camp as other great historicalmilestones, particularly the Industrial Revolution. Yet when we ask why theIndustrial 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 socialchange. It gave rise to mass production and, through mass production, to asociety in which wealth was not confined to the few.In somewhat similar fashion, computers promiseto revolutionize the structure of American life, particularly as they free thehuman mind and open new possibilities in knowledge and communication. TheIndustrial Revolution supplemented and replaced the muscles of humans and animalsby mechanical methods. The computer extends this development to supplement andreplace some aspects of the mind of human beings by electronic methods. Andit′s the capacity of the computer for solving problems and making decisionsthat represents its greatest potential and that poses the greatest difficultiesin predicting the impact on society.  According to the passage, whenwill a spear or a robot has the quality of technology 查看材料
选项 A.When it is utilized by human beings.B.When it is used to produce new products.C.When it has some culture meanings asphysical object.D.When it is useful for both man andanimal.
答案A
解析细节题。根据第二段中的“Until humans use a spear to huntgame or a robot to produce machine parts, neither is much more than a solidmass of matter.”可知．除非人们用矛去捕获猎物或用机器人去生产机器零件，否则二者都只不过是硬邦邦的物体而已。也就是说只有这些东西为人类所用的时候，它们才具有技术特性，故选A。
