Your roommate was given an antibiotic for strep throat. After three days
she is feeling fine and asks you if she should stop taking the antibiotic
and save the pills for the next time she has a sore throat. Your best
response would be:
A. Yes, quit taking them, because the role of antibiotics is to give the
body's immune system enough time to fight off the infection, so she
doesn't need the pills after she feels better.
B. No, she must finish her course of treatment because repeated exposure
to antibiotics may result in drug resistant strains.
C. Yes, the antibiotics were very potent and able to kill off the infection
more quickly than anticipated.
D. No, the infection is really not under control yet to the point that her
immune system can finish fighting it off.

Many residents in a small town have developed a bacterial
infection. Two students hypothesize that the bacteria are coming
from the town’s drinking water. They look for the bacteria in
water samples from the lake that supplies 80 percent of the
town’s drinking water. When they find no bacteria, the students
conclude that the town’s residents are not getting the bacteria
from their drinking water. Which is a source of error in the
students’ experimental design?
A. water from the lake was not tested for other possible pathogens
B. residents of other nearby towns were not tested for the bacteria
C. the residents' genetic predisposition for getting ill was not
determined
D. other sources of drinking water were not tested for bacteria
