1.        In the 1980’s the rate of increase of the minority population of the United States was nearly twice as fast as the 1970’s.

(A) twice as fast as

(B) twice as fast as it was in

(C) twice what it was in

(D) two times faster than that of（C）

(E) two times greater than

以前的讨论都是问B为什么不对，我想问一下E为什么不对，是因为没有补出省略的部分吗？two times greater这个表达对吗，我对倍数的表达比较晕，问个弱弱的问题，请帮忙解答一下。

对，错在没有补出比较对象。

比较结构最重要的考点就是比较对象要明确。

这里变成rate和the 1970's（即七十年代）比较了。
