Original sentence: "  This shows that the strong interaction is a gauge symmetry, and requires the existence of gauge theory.For example, a description of interacting quark color charges are arbitrarily defined and reported, in different locations, and at different times.However, the mathematical results of the quark interactions, must agree, independent of the variations.This description (theory) accurately predicts the existence of the  8 force mediators (gluons), and ultimately the "quark to quark interactions
