  The magnitude of B-mode polarization in the cosmic microwave background as
measured by BICEP2 favours models of chaotic inflation with a quadratic $m^2
\phi^2/2$ potential, whereas data from the Planck satellite favour a small
value of the tensor-to-scalar perturbation ratio $r$ that is highly consistent
with the Starobinsky $R + R^2$ model. Reality may lie somewhere between these
two scenarios. In this paper we propose a minimal two-field no-scale
supergravity model that interpolates between quadratic and Starobinsky-like
inflation as limiting cases, while retaining the successful prediction $n_s
\simeq 0.96$.
