  In view of the major advances achieved by the CLAS experiments in studying
the N* electroexcitation amplitudes, as well as further extension of these
studies in the experiments with CLAS12, we present an approach for the
evaluation of the resonant contributions to inclusive electron scattering off
protons. For the first time, the resonant contributions are determined from the
experimental results on N* electrocouplings available from the data analyses of
exclusive meson electroproduction off protons. This is a useful benchmark for
future endeavours on understanding the transition region between low and
high-energy regions, strongly related to tests on quark-hadron duality.
