In hopes of successfully treating the patient's worsening infection, you look to the collection of antibiotics stocked at the hospital's pharmacy. There are four yet untested antibiotics available to you, in addition to the four antibiotics to which you know the superbug is resistant. The yet untested antibiotics include chlorotetracycline, rifazil, ampicillin, and ciprofloxacin. Based on what you have learned experimentally and theoretically about these antibiotics in regard to superbug membrane permeability and mechanism of resistance, rank the new antibiotics based on their likelihood of successfully treating the patient.
