请教NN一道PREP的题目，看了笔记也还不明白~~谢谢

As the former chair of the planning board ofr 18 consecutive years and a board member for 28 years, Joan Philkill attended more than 400 meetings and reviewed more than 700 rezoning applications.

A. As the former

B. The former

C. Former

D. She was

E. As the

答案是e

解释说 a选项：as the former chair...for 18 consecutive years 不符合逻辑，而且主语谓语attended..., 如果是former chair, attended。。。也是不符合逻辑的

有没有人可以解释一下这里不符合逻辑的逻辑是什么，former表示前任，那么动词用过去时attended，有那里不符合逻辑？

作为一个公司的前任主席这个现象持续18年是不符合逻辑的，或者说不能用时间修饰的。

比如说“作为她连续5年的前男朋友。。。"也是不符合逻辑的。
