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.

1. which amounts to a little less than half the population of the state, down from nearly three-quarters only a decade ago
   
2. which amounts to a little less than half the population of the state, down from a decade ago, when it was nearly three-quarters
   
3. 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
   
4. amounting to a little less than half the population of the state, down from nearly three-quarters a decade ago
   
5. amounting to a little less than half the population of the state, down from what it was a decade ago by nearly three-quarters
   我选了E，但是正确答案是D，求大牛解释……

首先E答案中的it指代不清，what it was结构不明的
然后还改变的原意
题目的原意是non-Hispanic Whites 现在占加州人口的比例从原来的快四分三跌倒现在的不到一半
而E答案变成了从原来的多少降到了四分之三
down from……与down from  ……by……的意思是不一样的

同意 LS的  

down from  四分之三  现在是不到一半  这是 D
而E 是  从原来 的  降了四分之三    ，这搞得跟数学似地  ，比如 原来 是 12  现在时 3 降低了 9 ， 9是 12 的四分之三    这是 降低了 四分之三的 意思  是 E 的意思  

这个意思完全 不对   即使原来是 百分之百  它降低四分之三  现在  也只剩  四分之一了  跟前面的  不到一半  的表达 有矛盾 啊  。
