Query: Gauge Coupling Unification due to Large String Threshold Corrections   We show that large string threshold corrections can reconcile the string and
MSSM unification scales in fermionic strings. This requires at least three
moduli with large VEVs which are different from each other and MSSM states
arising in an unconventional manner from the string spectrum. The former is
easily achieved by supersymmetry breaking by both hidden gaugino and matter
condensation whereas the latter needs to be seen in explicit string models.
