求助XDF NN，关于这道题的平行 prep2--206

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 three-quarters only a decade ago.


D    amounting to a little less than half the population of the state, down from nearly three-quarters a decade ago(D)
我想问这道题 amounting... & down from 是一组平行对吧？那中间不用and作为连词对吗？

两者不该是平行关系，down from作后置定语修饰a little less than half这个比例数字。
