When you use include and require you get the result of the page you're referencing being included. When you use require_once it checks and sees that the page has already been loaded using require, so it returns true to tell you that it has been loaded successfully at some point.
That's exactly it, and you're trying to duplicate include. When you require_once something that hasn't been included or required before, you will get the return value.
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.
