Query: Branes and Theta Dependence   We use the fivebrane of M theory to study the $\theta$ dependence of four
dimensional $SU(N_c)$ super Yang-Mills and super QCD softly broken by a gaugino
mass. We compute the energy of the vacuum in the supergravity approximation.
The results obtained are in qualitative agreement with field theory. We also
study the $\theta$ dependence of the QCD string tension via the fivebrane.
