  It is argued that when the dimension of space is a constant integer the full
set of Einstein's field equations has more information than the spatial
components of Einstein's equation plus the energy conservation law. Applying
the former approach to the decrumpling FRW cosmology recently proposed, it is
shown that the spacetime singularity cannot be avoided and that turning points
are absent. This result is in contrast to the decrumpling nonsingular spacetime
model with turning points previously obtained using the latter approach.
