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

作者选了E.

我认为E中 S0........,SO......., THAT 不能确定. 有谁了解这种句型么?

倒装(See og20 for so...that倒装)并省略was。等于：

Frances Perkins’ investigations of the garment industry were so dogged , and her lobbying for wage and hour reform was so persistent, that Alfred E. Smith and Franklin D. Roosevelt recruited Perkins to work within the government, rather than as a social worker.

E加个and感觉会好些，但它是5个烂苹果里最不烂的一个。
