Quasifree (e, e'p) reactions at Q(2) similar to 0.1 GeV2 observed a strong quenching of the single-particle valence strength. This precluded unambiguous measurement of nuclear transparency in quasifree (e, e'p) reactions at Q(2) greater than or equal to 1 GeV2. We argue that the high-energy nuclear transparency in the transverse kinematics weakly depends on the probability of the short-range correlations and can be accurately determined using information on the cross section of the (e, e') reaction at x similar to 1 and Q(2) similar to 1-2 GeV2. We find that the Glauber approximation well describes E91-013 and NE18 (e, e'p) data at 2 less than or equal to Q(2) less than or equal to 4 GeV2 without any significant quenching. This gives further support to our observation that the quenching of nuclear levels strongly depends on the resolution (Q(2)) and practically disappears at Q(2) greater than or equal to 1 GeV2.
