Q41P84

Until Berta and Emst Scharrer established the concept of neurosecretion in 1928, scientists believed that either cells secreted hormones, which made them endocrine cells and thus part of the endocrine system, or conducted electrical impulses, in which case they were nerve cells and thus part of the nervous system.



A.either cells secreted hormones, which made them

B.either cells secreted hormones, making them

C.either cells secreted hormones and were

D.cells either secreted hormones, in which case they were

E.cells either secreted hormones, which made them

知道这里不能选择E，因为which错误地指代了hormones，而不是前面的整个情况~~但是我想知道D中的they会不会有修饰歧义呢？为什么没有？

同问，而且关于D，E也有不解的地方

这个貌似是个平行的问题

后面也有they were
S+v+o, which s + v + o. 这里后面定语从句的s是不是和主句平行的?即代词指代主语?请指正
