  The problem of understanding the nuclear effects observed in lepton-nucleus
deep-inelastic-scattering (the EMC effect) is still with us. Standard nuclear
models (those using only hadronic degrees of freedom) are not able to account
for the EMC effect. Thus it is necessary to understand how the nuclear medium
modifies quark wave functions in the nucleus. Possibilities for such
modifications, represented by the quark meson coupling model, and the
suppression of point-like-configurations are discussed, and methods to
experimentally choose between these are reviewed.
