Successful innovations have driven many older technologies to extinction and have resulted in higher productivity, greater consumption of energy and increased demand for raw materials, accelerated flow of materials through the economy and increased quantities of metals and other substances in use each person. The history of industrial development abounds with examples.
In 1870, horses and mules were prime sources of power on U. S. farms. One horse or mule was required to support four human beings—a ratio that remained almost constant for many decades. At that time, had a national commission been asked to forecast the horse and mule population for 1970, its answer probably would have depended on whether its consultants were of an economic or technological turn of mind. Had they been "economists" , they would probably have projected the 1970 horse or mule population to be more than 50 million. Had they been "technologists" , they would have recognized that the power of steam had already been used in industry and land and ocean transport. They would have recognized further that it would be the prime source of power on farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.
In the second paragraph, the author suggests that "economists" would ______.
选项
A、plan the economy through yearly forecasts.
B、fail to consider the influence of technological innovation.
C、value the economic contribution of farm animals.
D、consult the national commission on the economy.
答案
B
解析
推理题。在第二段中,作者比较了经济学家和技术专家对于未来一百年的预测,明显经济学家未把科技的因素纳入到预测中,而技术专家就不同了。故B正确。
