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.
(B)as there are households where the
(C)as those whose
(D)than compared to those where the
(E)than there are whose
Ans:B
ㄧ看到there are就想到莫說的虛字少選 就先被我劃掉了

的確 以平行結構來看(B)最好
但我想請問A為什麼錯ㄚ
因為我看到題目as many households where the children and grandchildren are living in their grandparents' home as
as 後加many households所以要找個平行的
就選了(A)
不選(B)除了因為"虛字少選" 加上我想平行是和第一個as後的結構平行
結果錯啦....

謝謝大大解答!
