大全补充111（未讨论）

111.  Too old to bear arms himself, Frederick Douglass served as a recruiting agent, traveled through the North to exhort Black men to join the Union army.

(A) traveled through the North to exhort

(B) and he traveled through the North and exhorted

(C) and traveling through the North exhorted

(D) traveling through the North and exhorted（E）

(E) traveling through the North and exhorting

我的问题是：b为什么不行？用and是可以连接连个句子的呀？将它理解成两个句子有何不妥？多谢！

E，比较好，用来解释他的工作内容，做伴随状态

请查找and的用法，其中有两个含义，即 1。先后； 2。因果。

这里如果用and,会产生歧义
