2. and lobbying for wage and hour reform was persistent, so that
3. her lobbying for wage and hour reform persistent, that
4. lobbying for wage and hour reform was so persistent,
5. so persistent her lobbying for wage and hour reform, that

为何选E啊,大家给点看法

It's the "so...that" phrase again and this time comes with parallelism.

so dogged ... so persistent...that... E keeps the structure parallel and therefore is the best answer

谢谢！！！懂了

e：1，为什么两个so之间没有and相连？

  2，so 句子，so 短语 难道正如楼上所言第二个so中的be省略了？

期待您的解答，谢谢

就算be省了，两段话之间的and也不能省啊

还是说so persistent...这句话是做其他成分？？？不是并列？？
