some geologists argue that if oil is as common in unsampled areas of the world as it is in those already sampled, our current estimate of reserves that exist underground must be multiplied by a factor of 10,000. From this we can conclude that we can meet the oil needs of the entire world for at least five centuries, even assuming that future consumption grows at an accelerating rate.

To reach the stated conclusion, the author must assume which of the following?
A. it is possible to recover the oil contained in unexplored areas of the world
B. The consumption rate for oil will not grow rapidly
C. Oil will remain an important evergy source for at least 500 years
D. The world will achieve and maintain zero population growth
E. New technology will make oil discovery and drilling more feasible than ever before.

我选的是C,但是答案是A。我不能理解，会不会是答案错了...求解释

不对啊，就算没有C，也对啊。Oil不是主要能源了，那更可以用至少5个世纪了啊

嗯，是的  少了一个步骤。谢谢高手指点！

题说，科学家说要是未勘测地区跟已勘测地区油一样多，就算需求增长，咱也不愁了。
假设就是那些油得挖得出来啊，要不还得愁

oil的储备量和oil的消耗量之间缺少一个重要的东西，就是是否能挖掘出

来用。是不是主要资源是不相关的事情。这种consumption跟着题目的逻辑和

里面的因素走，不要想太多。
