GWD大美句？

Xiaotongdi

The Acoma and Hopi are probably the two oldest surviving Pueblo communities, both dating back at least a thousand years.

1. both dating
   
   
2. both of which have dated
   
   
3. and each has dated
   
   
4. and each one dating
   
   
5. each one of which date
   
   

A大美句？B是因为没有and连接吗？

A是独立主格。
B中which指代的是two oldest surviving Pueblo communities，带入即both of two oldest surviving Pueblo communities可以发现both和two重复
话说终于遇到一个the noun1 and noun2 + plural verb了.

请教斑斑 会不会是因为B和E：each of which是修饰communities,但是原文both暗示说两者都，逗号后面应该修饰主语A&H，A&H和communities是从属关系，不同的。所以用A的独立主格修饰整个句子/主语？
