Just be calm, take a breath, speak clearly, and don't be afraid to ask to repeat a question to clarify something if you're unsure. Be confident and smile and I'm sure you'll do fine. Unless you're interviewing for a managers job there, I wouldn't worry about it.
Good luck.
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.
