1. AThis interval cannot be predicted, because ethanol clearance instead depends mainly on hepatic blood flow rather than enzyme activity
2. BThis interval increases fourfold, because saturated enzyme kinetics cause the clearance rate to fall further as readings rise
3. CThis interval stays exactly the same, because clearance depends on the proportion of ethanol present, not on total intake consumed
4. DThis interval roughly doubles, because the liver clears only a fixed quantity of ethanol per hour once saturated
5. EThis interval is roughly halved, because higher blood ethanol readings paradoxically speed up enzymatic clearance
