A. has been dated to be 1.23 Billion years old and thus is
B. has been dated at 1.23 Billion years old and thus
C. have been dated to be 1.23 Billion years old and thus are
D. have been dated as being 1.23 Billion years old and thus
E. have been dated at 1.23 Billion years old and thus are

就不明白为什么thus are evidence(这样的话，evidence不是应该用复数形式么？？？evidences???)
求指导。。。

简单的举个类比

”他口袋里面的20个苹果是他偷盗的一个证据“

主语的复数不代表表语一定是复数

我感觉LS的说法不对

主语，be动词，表语；这3个难道不应该数量一致吗？？

20个苹果是一个证据，20 apples are a evidence？？这样的句子是正确的吗？
原句的说法，samples are evidence，没s，这样是对的？

求牛牛指导。
