Query: Modeling Quintessential Inflation   We develop general criteria to construct unified frameworks for inflation and
quintessence which employ a unique scalar field to drive both. By using such a
minimal theoretical framework we avoid having to fine-tune couplings and
mass-scales. In particular the initial conditions for quintessence are already
fixed at the end of the inflationary epoch. We provide concrete realizations of
the method which meet all inflationary and quintessence requirements, such as
the COBE normalization and the resulting spectral index n = 0.97, which is in
excellent agreement with the latest CMB data.
