You should also consider foreign keys when the number of potential choices is large. That's one of the reasons to consider using FK for countries or states. Otherwise, you're effectively hard-coding a lot of data in your source code.
I would use choices where the choices wouldn't change over time. If they would, a FK with a new model would be better.
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.
