On the assumption that a heavy virtual photon behaves like a parton-antiparton pair when participating in the strong interaction, we predict that the total cross section for $e^{+}{e}^{-}\to \mathrm{hadrons}$, as $q^2\to \infty$, behaves like $C{q}^{-4\mathrm{}}{\mathrm{}\left(\right|\mathrm{}{q}^2\left|\ln \right|q^2\mathrm{}\left|\right)\mathrm{}}^{-1\mathrm{}}$ for spin-0 partons, and like $C^{\prime }{q}^{-4\mathrm{}}{\left(\ln \right|q^2\mathrm{}\left|\right)\mathrm{}}^{-1\mathrm{}}$ for spin-$\frac{1}{2}$ partons, where $q^2$ is the virtual photon's mass squared. This provides a simple, yet important test of the parton dual-resonance model for deep-inelastic lepton-hadronic scattering, proposed in a previous paper.
