The Sorites paradox arises from problems with which concept?

Vague predicates (e.g., 'heap')

Self-reference in set membership

Indeterminate future contingents

Which classic resolution approach for Russell’s paradox modifies naive set comprehension by restricting which sets can be formed (e.g., via axioms)?

Axiomatic set theory (e.g., Zermelo–Fraenkel)

A standard formal response to the Liar paradox that rejects the law of bivalence while preserving classical logic is called what?

Truth-value gaps (e.g., supervaluationism)

Which resolution treats some paradoxical sentences as both true and false (accepting truth-value gluts)?

Dialetheism / paraconsistent logic

Classical extensional set theory

The 'Barber paradox' is best described as a reformulation of which underlying logical problem?

Russell's paradox (self-referential set membership)

The Liar paradox (self-referential sentence truth)

Zeno's paradox (motion and division)
