Chapter 5: Out of Bounds at All Times No Exceptions

What does it say that we only actually meet the father in the book in Chapter 5 even though he is the one causing much of the action in the book?
It shows that he is a busy man and we wont have much interaction with him throughout the book because he's caught up in work.

the mother says: ‘We should have never let the Fury come to dinner. Some people and their determination to get ahead.’ What theme does this introduce regarding the role of ambition and causing harm? dont understand the question

How does Bruno's father speak to him? Give an example to support your answer. Bruno's father speaks to Bruno like he's a soldier, eg "He opened the door and Father called him back in for a moment, standing up and raising an eyebrow as if he'd forgotten something... Heil Hitler he said"

How would you compare the way Bruno speaks about the world to his father's? Do they both comment about what is going on around them the same?
I would compare the way Bruno speaks about the world and his father's to be another use of juxtaposition. No they don't.

How does the father rationalise every concern that Bruno has? Father rationalises every concern Bruno has by saying it is what it is and has to be done. He's also bouncing around the truth to convince Bruno and himself that its right.

What is ironic about what the father says when he comes around the desk and talks to Bruno about his childhood? Whats ironic about what the father says to Bruno about his childhood is that it sounds like he's making the story up and uses and excuse as an example but the example is something every child does including Bruno, also the depth of what he had to do is no where near Bruno moving homes.

Do you think that the father really cares about Bruno? Why/why not? I think the father cares about Bruno and wants the best for him, i just think in this instance he is short tempered and doesn't care about what Bruno has to say because they're not moving back.

Do you think that Bruno understands what he is saying when he says 'Heil Hitler!'? No and it even says in the book that he doesn't understand it, he just assumes it means goodbye have a nice day.

How is juxtaposition used in Bruno's description of their boarding the train to Auschwitz? Juxtaposition is used by having the Jews in one train and the non Jews in the other. The non Jew train had seats, fresh air, room to move around and seemed like a pleasant place to be. The Jew train we assume was busy, no seats and just uncomfortable in general.

What is Bruno's reason for not saying anything to the Jews on the crowded train? How is this a representation of the greater German population?
Bruno's reason for not saying anything to the Jews on the crowded train is because it would make Gretel furious. This is representation of the greater German population because it resembles a lot of their attitudes towards the Jews.
