The boy in the striped pyjamas questions

Q1,
Bruno seems younger than nine because of his height (too short) and his luck of knowledge, of what’s really going around him. He’s naïve and not aware of the Holocaust and what’s been done to the Jewish people in “Out -With” as he calls it. “Out- With” is Bruno’s mispronunciation of “Auschwitz”. And same has pronouncing the “Fuhry” instead of the Fury. He is just blanked on vocabulary and understanding of things.
Q4,
The thing about the house at out-with that makes Bruno “cold and unsafe” is because he’s not used to leaving there, and the condition of their new house, the location and the surroundings. He is very curious to know why they had to leave their big house in Berlin, stay in Auschwitz. He doesn’t find that place safe because of the quietness around it, and he has no friend anymore to play with compared to his house in Berlin. Bruno doesn’t understand why there’s too sided fence. He doesn’t get why the people in the other side of the fence are dressed in striped pyjamas all day long, and why his father also goes there to visit but they’ve never invited anyone back for dinner.
Q12,
I agree with the statement made, that we have no rights to ignore the past because its unpleasant or refuse to let reality intrude on our preference for fun and for laughter. It’s true that we shouldn’t let the past fade away just because it happened a long time ago and we have nothing to do with it. History is very important to not make the same mistakes again and repeat what was done in the past. Whatever happened in history can sometimes be repeated in the future, that’s why to avoid the repetition of a certain history it has to be told, whether it’s pleasant or unpleasant.
