Some geologists argue that if oil is as common in unsam-pled 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？
