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

答案选A

C选项的错误是否在于将原句的both换为each呢?

谢谢

主要是each 强调 每一个    而both强调 两个都

请问B错在哪儿呢？

I think you should have a benchmark to use past perfect tense.

B both of which have dated. " have dated" means this "date" action actually happened in the past and last to now and probably will continue in the future. I don't think that's the meaning the author originally intended.

请问，date back to 和date back有区别吗？
