Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power(that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants)is unchanged at thirty-five dollars. Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability?
选项
A、The cost of oil has fallen dramatically.
B、The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment.
C、Technological changes have increased the efficiency of oil-fired power plants.
D、Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants.
E、When the price of oil increases, reserves of oil not previously worth exploiting become economically viable.
答案
C
解析
本题思维比较简单,主要是阅读能力。①太阳能经济可行性的门槛=②太阳能发电机的成本一③新的燃油发电机=35美元。让我们解释为什么②降低了,但②一③仍然是35美元,思维只有一点,那就是③也降低了。所以在读懂题目的情况下,(C)为什么正确一目了然。(A)易误选,但(A)里讨论的“cost”并不等于推理里面的“price”。
