答案A。可是逗号后面each of which are为什么用的是are? 根据each of n. 结构，中心词应该是each,而不是which(指代主句的teech) ，所以我觉得应该是each of which is ,虚心求教！

斑竹能略作解释吗？

谢谢！

A 的 each of which are显然不对；

B which are each ready to 中的each用法unidiomatic, 而且整句话的意思也没有逻辑；

C each one of which are ready 同A

D 只有主语， 没有谓语， 严重错误；

E 逻辑和语法都正确； each one ready to slide into the appropriate position whenever an active tooth is lost or worn down 作为独立主格修饰前面的句子， 不太好理解， 但正确。
