1. Both fighters had to honor code
Must put the story in there.
The whole To Kill A Mockingbird was told from a point of view when Scout was grown up so she realized then, but as a child she was innocent so she did not realize that they was a mob in the first place. So for a short answer No she was aware.
To fix the sentence, change "," after 2004 to ";" and remove the "and" before scientists. It makes the sentence sound better.
I hope that helps!
