Good question.


Well, we have to focus here on what is important: She was criticized

OR put in a simple way: for what reason/s? why she had critics ?

If she was criticized NOT for X (working hard or less) but for Y

However, reading the sentence per see we do not have enough information or data to assess if she was a powerhouse or not BUT if I should say: she is a hard worker or not ?? I would say yes but, again, this is beyond the point

Hope this helps
