  "abstract": "We propose studying the mechanism of factorization in exclusive decays of the form B->D(*)X by examining the differential decay rate as a function of the invariant mass of the light hadronic state X. If factorization works primarily due to the large N_c limit then its accuracy is not expected to decrease as the X invariant mass increases. However, if factorization is mostly a consequence of perturbative QCD then the corrections should grow with the X invariant mass. Combining data for hadronic tau decays and semileptonic B decays allows tests of factorization to be made for a variety of final states. We discuss the examples of B->D^*\\pi^+\\pi^-\\pi^-\\pi^0 and B->D^*\\omega\\pi^-. The mode B->D^*\\omega\\pi^- will allow a precision study of the dependence of the corrections to factorization on the invariant mass of the light hadronic state.",
