The Whitehead Problem is a fundamental question in abelian group theory that asks whether every abelian group \( A \) satisfying \( \text{Ext}(A, \mathbb{Z}) = 0 \) must be free, thereby exemplifying a prototypical independence result in mathematical logic due to its undecidability in Zermelo-Fraenkel set theory with the Axiom of Choice.
