If this is the Diary of Anne Frank, which I believe it is, my guess would be that she is either being critical or she genuinely wants to help them, A or B. It's been so long since I read this, but from what I can remember of Anne, she seems like the type to genuinely want to help them, so I'd guess B.
The first one: The catapult stood on a platform in the castles tower before the tower was destroyed.
I'm pretty sure the answer is A
