So you definitely have more structure this time but you still lacking proper character development.
Katherine is making radical decisions in the first chapter and we learned practically nothing about her or why she is doing what she's doing. I've explained in the golden rules to make these radical actions make sense that you have to show the reader the thought process.
Additionally: you are definitely improving on when exposition should be revealed. But make sure it's addressed naturally. Make note as to why Katherine doesn't know and has to be explained since it appears to be the very basics.
Was this info a secret to the public or is Katherine not aware of the world she lives in and doesn't pay attention to this.
If someone asked me who the president of the United States while we are in the U.S., I will address how weird it is that the person doesn't know at some point when I give the answer.
Same logic should apply in your story when giving basic exposition.
