The cost of the average computer logic device is falling at the rate of 25 percent per year, and the cost of the average computer memory device at the rate of 40 percent per year. It can be concluded that if these rates of cost decline remain constant for a period of three years, at the end of that time the cost of the average computer memory device will have declined by a greater amount than the cost of the average computer logic device. Accurate information about which of the following would be most useful in evaluating the correctness of the conclusion above?
选项
A、The number of logic devices and memory devices projected to be purchased during the next three years.
B、The actual prices charged for the average computer logic device and the average computer memory device.
C、The compatibility of different manufacturers’ logic devices and memory devices.
D、The relative durability of logic devices and memory devices.
E、The average number of logic devices and memory devices needed for an average computer system.
答案
B
解析
本题由一个比例数据而得出一个外推与“数量”有关的结论,那么推理成立所隐含的假设是“logic device与memory device的最初成本基本相似”。而评价大多针对隐含假设。(B)针对隐含假设,指出logic device和memory device两者的actual prices是多少。若二者原来成本基本相同,那么就支持了上面推理;若memory device的actual price要远远小于logic device的actual price,则反对了段落推理,所以(B)是一个评价;(A)与(E)中的“number”与成本没有直接关系;(C)中的“compatibility”与(D)中的“durability”均与“成本”没有直接关系,因此(A)、(C)、(D)、(E)都不对。
