1) "Bonjour d'Australie" 2) "Allo d'Australie" ("Allo" is the first word we say when we answer a phone call) 3) "Salut d'Australie" (informal) 4) "Coucou d'Australie" ("Coucou" is a little friendly word to say hello, we'd rather say "Un petit coucou d'Australie" literally "A little hello from Australia") So correct answers are 1, 2 and 4.
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.
