  We analyze the dynamics of model supercooled liquids in a temperature regime
where predictions of mode coupling theory (MCT) are known to be valid
qualitatively. In this regime, the Adam-Gibbs (AG) relation, based on an
activation picture of dynamics also describes the dynamics satisfactorily, and
we explore the mutual consistency and interrelation of these descriptions.
Although entropy and dynamics are related via phenomenological theories, the
connection between MCT and entropy has not been argued for. In this work we
explore this connection and provide a microscopic derivation of the
phenomenological Rosenfeld theory. At low temperatures the overlap between MCT
power law regime and AG relation implies that the AG relation predicts an
avoided divergence at $T_c$, the origin of which is traced back to the
vanishing of pair configurational entropy, which we find occurs at the same
temperature. We also show that the residual multiparticle entropy plays an
important role in describing the relaxation time
