Hi Igor' and Astrid,</div>

When Astrid write inclusive structure function or inclusive electron scattering that means sum over ALL inclusive channels. I can not see need for further clarification of this point.</div>

Astrid was saying on the mass range for the resonances which were included into evaluation of the resonant contribution. Mass of the resonance is well defined quantity listed in PDG. She never saying about W. However, it may be usefull to say that we are
analyzing inclusive electron scattering observables at W<2.0 GeV and Q^2 from 1.0 to 5.0 GeV^2.</div>

<div dir="ltr">Hi Igor,
<div><br>
</div>
<div>It's W = 1.75 - I will specify that in the abstract to APS. I am more interested in N* and Delta resonances; indirectly I'm using pion, two-pion and eta production data for N* and Delta electrocouplings: do you think this should be specified in the abstract?</div>

<div>Thank you!</div>

<div><br>
</div>
<div>One small question is - your energy 1.75 GeV is Eg or W? Then what mesons you are going to talk - pions, eta, eta', kaons?</div>

<div><b>Polarized and unpolarized proton structure in the resonance region: exclusive data-driven insights<br>
</b></div>
</span>
<div><i>Nucleon resonance contributions to the inclusive proton structure functions are computed from resonance electroexcitation amplitudes in the mass range up to 1.75 GeV extracted from CLAS exclusive meson electroproduction data. Taking into account interference
effects between nucleon resonances, the resonant contributions are compared with inclusive proton structure functions evaluated from the available data in the resonance region. Resonance contributions remain substantial over the entire range of photon virtualities
< 4 GeV^2 where electroexcitation amplitudes have been obtained. Their Q^2 evolution displays pronounced differences in the first, second and third resonance regions. We compare the structure functions in the resonance region with those computed from parton
distributions fitted to deep-inelastic scattering data, and extrapolated to the resonance region, providing new quantitative assessments of quark-hadron duality in inclusive electron-proton scattering. Ultimately, this paves the path to a physically founded
combined description of the connection between the low and high-energy regimes.</i></div>
