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 need's 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 energy source for at least 500 years.
D. New technology will make oil discovery and drilling more feasible than ever before.
