Query: Polynomially Convex Arcs in Polynomially Convex Simple Closed Curves   We prove that every polynomially convex arc is contained in a polynomially
convex simple closed curve. We also establish results about polynomial hulls of
arcs and curves that are locally rectifiable outside a polynomially convex
subset.
