A woman struggling with a bacterial illness is prescribed a month's supply of a potent antibiotic. She takes the antibiotic for about two weeks and feels much better. Should she save the remaining two-week supply, or should she continue taking the drug?
a) She should continue taking the drug until her immune system can completely eliminate the infection. Otherwise the remaining bacteria in her system may recover, and they will probably be resistant.
b) She should save the drug for later, because if she keeps taking it the bacteria will evolve resistance.
c) She should continue taking the drug because otherwise the bacteria will evolve by genetic drift
d) She should save the drug because antibiotics are in short supply and she may need it to defend herself against a bioterrorism incident.
e) She should save the drug for use the next time the illness strikes
