Recent experimental determinations of the spectral index describing the
scalar mode spectrum of density perturbations encourage comparison with
predictions from models of the very early universe. Unlike extended inflation,
Induced-gravity Inflation predicts a power spectrum with $0.98 \leq n_s \leq
1.00$, in close agreement with the experimental measurements.
