With the 2nd solution, you have to manually call the previous functions, making it hard to remove specific listeners (which, to me, sounds like something you'd rather want than clearing all listeners), while on the first solution, you can only clear them all at the same time, unless you want to emulate the first functionality.
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.
