单选题 When the rate of inflation exceeds the rate of return on the most profitable investment available, the difference between those two rates will be the percentage by which, at a minimum, the value of any investment will decline. If in such a circumstance the value of a particular investment declines by more than that percentage, it must be true that______.
Which one of the following logically completes the argument?

A、 the rate of inflation has risen
B、 the investment in question is becoming less profitable
C、 the investment in question is less profitable than the most profitable investment available
D、 the rate of return on the most profitable investment available has declined
E、 (E) there has been a chance in which particular investment happens to be the most profitable available

【正确答案】 C

【答案解析】[解析] 根据本题的论述可知，当某一特定投资的价值下降的百分比超过盈利最大的投资价值下降的百分比时，这个投资的收益率一定没有盈利最大的投资的收益率高，也即这个投资的利润率没有现有的利润最高的投资的利润率高。根据上述分析可知(C)是正确的，而(E)是错误的；(A)、(B)和(D)均不能从上述段落中合理地推出。
