GWD上的语法题，很纠结

A recent United States Census Bureau report shows that there are more than three times as many households where the children and grandchildren are living in their grandparents’ home as compared to households where the grandparents are living in their children’s or grandchildren’s home.

A.as compared to households where the

B.as there are households where the

C.as those whose

D.than compared to those where the

E.than there are whose
A选项怎么错了呢？我觉得不需要重复there are ,为什么选B？感谢！

as....as 本身就有对比的意味   翻译过来就是 和。。。一样
所以 as...as后面跟上compared 就有redundant的嫌疑
至于为什么选B，SC是选5个里面最好的。尽管楼主认为 there are多余，但是C whose 不对 D E的 than错的很明显，A B比较，重复there are应该是小毛病，所以选B
