Query: Resolution of Curvature Singularities in Higher Derivative Gravity   We consider possible resolutions of singularities in a contracting
anisotropic universe for a class of higher derivative gravity theories. We give
evidence that for our models the big crunch singularity may be replaced by a
nearly flat Minkowski-like phase before the Universe reenters an anisotropic
expansion in a time-symmetric manner.
