Can you play nintendo ds lite games on a nintendo 3ds?

No, of course not. Because all nintendo consoles support backward compatiblity, you can play all ds games on 3ds,just without 3d effect,but you can't play 3ds games on ds.

No, they only work on a Nintendo 3DS since the size is way off and the other DS systems aren't capable of supporting 3D.

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.
