  We study $eA$ scattering in a model where the total nuclear structure
function is a convolution of components $W_N$ for an isolated nucleon and
$W_{\NA}$ for a nucleus composed of point-nucleons. $W_N$ is represented by its
elastic and lowest-energy inelastic parts, while $W_{\NA}$ is computed from its
asymptotic limit, supplemented by final state interactions due to binary
collisions between the knocked-out and core nucleons. $(q/M)W_{\NA}$ per
nucleon appears to be practically independent of mass number $A$ and momentum
transfer $q$. Consequently, predicted inclusive cross sections per nucleon for
given kinematic conditions hardly depend on the target and the same can be
extracted from the data. Exceptions are low energy loss regions, where
relatively small cross sections are shown to be sensitive to details of the
single nucleon momentum distribution and to FSI, involving multiple collisions.
The agreement with the data is good.
