GWD 10- 23

Even though there is a short explanation to this question in the list, it is not quite clear.  Could you tell me why not to choose A but E.

Q23

For the first time in the modern era, non-Hispanic Whites are officially a minority in
California, which amounts to a little less than half the population of the state, down from
nearly there-quarters only a decade ago.
A. which amounts to a little less than half the population of the state, down from
nearly three-quarters only a decade ago
B. which amounts to a little less than half the population of the state, down from a
decade ago, when it was nearly three-quarters
C. and that amounts to a little less than half the population of the state, down from a
decade ago, when they were nearly three-quarters
D. amounting to a little less than half the population of the state, down from nearly
three-quarters a decade ago
E. amounting to a little less than half the population of the state, down from what it
was a decade ago by nearly three-quarters

Stick to the preferences of ETS who just systematically think that all "which" refer to the immediate word before them  .

Contrary to what we learned in middle school, ETS don't think "which" can be used to refer to the whole sentence that precedes it.

Hope it helps..

In this question, it is obvious that California cannot "amounts to a little less than.. the population".

这道题选择A为什么不对呢？ minoity的人数减少了，语义上过的去阿？

但是d答案有歧义，可以说是down/ from 3/4个十年（7.5年）前，也可以理解为原文的从十年前的

75%下降。

a答案的which就是修饰minority，少数民族现在一共有少于1/2的全加州的人口。虽然确实修饰whites似乎更好。而且通过动词are可以看出，whites就是minority，所以which修饰哪一个都一样。
