LSAT-11-4-24【rate】

24. 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) There has been a change in which particular investment happens to be the most profitable available.

哇，完全不知道原文说的什么意思～～key's c.

当通胀率高于收益最高的投资的收益率时，这两个率之间的差异，是所有的投资的市场价值至少要下降的比例。如果一种投资下降的多于这个比例，那么                    。

文中说，这个比率之间的差是最高收益率和通胀率之间的差，而下降的就是这个差值，那么既然下降的比最高的要多，说明差值大些，如果通胀率不变，那么一定是收益率低了。
