former must be removed not for grammatical reasons but to correct the meaning of the statement. With "former" left in there it would imply that the women had the role of "former chair" for the 18 consecutive years. Instead she was the actual chair for those 18 years. She is now the former chair but was not such during those 18 cons years. hope this helps.
former意思不对?
I did not pick up B because, I think if we use 'The former chair' , the sentence should be : the former chair of the planning board..and a former board member
the former说明连续18年做了前主席,逻辑不通,有former都错
这里不需要用former
