You are on the right track. The recursive approach will work. As far as I can tell from your sample data, each tuple first has string item, containing the key.
After that you have either another tuple or list as value, or a String value followed by a boolean true or false.
You are definitely on the right track. A recursive function is the way to go.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
