The only way that you can "shorten" this is to use the ternary operator.
Default function arguments can only take constant values, not expressions that are evaluated at runtime so your second option won't work.
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.
