Number Theory is full of such problems. And one can easily generate such problems in a foundational framework”

I and I think many readers of this discussion, would very much like to see such “simple questions about models of Set Theory which seem completely out of reach” explained in generally understandable terms, nicely laid out in one message. I especially would like to see the simplest such question you have in mind.

I’m not sure what the meaning is of the second sentence in the second paragraph above. Are you simply referring to the first paragraph above?
