We propose a method that involves quantities independent of strong interaction phases to test the factorization model in [ital D][r arrow][pi][pi] and [ital K[bar K]] decays. The method allows us to conclude that the factorization model correctly predicts [vert bar][ital A][sub 2][sup [pi][pi]][vert bar], overestimates [vert bar][ital A][sub 0][sup [pi][pi]][vert bar] and [vert bar][ital A][sub 1][sup [ital K[bar K]]][vert bar], and underestimates [vert bar][ital A][sub 0][sup [ital K[bar K]]][vert bar]. We rule out the Penguin mechanism as the solution to the disagreement between theory and experiment. We believe inelastic final state interactions are responsible for bridging the gap between theory and experiment.
