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

答案是D，请教A？

再请大牛确认这里的which到底指代whites还是minority?

补充一下LS，ETS的答复在89楼：

并且对于which的就近修饰问题回答的很含糊。这是个老问题啊~~

对于本题来说，逻辑上看which应当修饰non-Hispanic Whites（与主句的谓语修饰相同）

从就近原则上来看，那应该也是修饰California吧？不可能是minority

which amounts  单数 可修 a minority 或 California  歧意

which 加逗号隔开 修饰对象可近可远  要靠其他元素确立（如动词）

amounting to 句尾的分词从句就只往前修饰逻辑主语 无歧意

only为何省略就无从得知了
