As far as I can tell (with my limited knowledge of Spanish), "los documentos que os había enviado" means "the documents I had sent". I don't speak any French so I used a translation site to find that this is "Les documents que j'avais envoyé" in French. translate.google.com/translate_t# I have no idea if this has translated well through three languages, but I'm sure it will be close ;).
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.
