The argument that the dominant form of family structure today is not the nuclear family, but rather it is a family which is modified and extended, is based on a number of facts: the existence of three-generational families, the amount of vertical and horizontal communication between family subunits, and the extent to which family members offer assistance to one another.

(A) family, but rather it is a family which is modified and extended, is based on a number of facts: the existence of three-generational families

(B) family, but is instead a family that is modified and extended, is based on a number of facts: three-generational families exist

(C) family, which has been modified and extended, is based on a number of facts: the existence of three-generational families

(D) family but a modified extended family is based on a number of facts: the existence of three-generational families

(E) family, but also a modified and extended family, is based on a number of facts: three-generational families exist

答案是D。

但是，为什么E不正确？是因为facts:后面只能跟名词，不能跟句子吗？

but also 不能引导对比关系的句子

另外没有not only.but also 不能单独出现

明白了。所以这样的形式还是正确的

..... a number of facts: three-generational families exist

对吗？

不对.因未与后面的成分平行
