Skolem’s paradox concerns the existence of a set with a form of this property. For 10 points each:
[10e] Name this property, which can be countable or uncountable. Hilbert’s hotel thought experiment concerns the counterintuitive properties of sets with this property.
ANSWER: infinite [accept containing infinitely many elements or countably infinite or uncountably infinite]
[10h] Skolem’s paradox holds because countability lacks this property, as sets can be countable in one model but uncountable in another. A formula has this property in a class of models if its truth value is the same in all members of the class.
ANSWER: absoluteness [accept absolute formulas or absolute formulae]
[10m] Absolute sentences only contain quantifiers with this property. Functions in L (“big-L”) infinity have this property almost everywhere.
ANSWER: boundedness [accept bounded functions or bounded quantifiers]
