  We express nuclear structure functions $F_i^A$ as generalized convolutions of
the structure function of a nucleon and of a nucleus, composed of
point-nucleons. In computations of the latter we include Final State
Interactions and results for $F_2^A$ are compared with a few directly measured
data on C and Fe. The above $F_i^A$ are primarily used for predictions of the
TJNAF 89-008 inclusive scattering experiment of 4 GeV electrons on various
targets. Those cover a broad angular, and correspondingly wide $x,Q^2$ range,
where the nucleon-inelastic part dominates large sections of the covered
kinematics. The same model has been applied to the study of hitherto neglected
Final State Interaction effects in the nuclear component in EMC ratios in the
region $0.85\lesssim x\lesssim 0.25$.
