I think researchers have established that certain breeds of dogs can identify quite a few words. I've heard the G. Shepherd dog compared to the intelligence of a 4 year old child.
And whatever breed will learn to respond to whatever language is consistently used with them.
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.
