Antibiotics are drugs that kill harmful bacteria that have infected the body. However, doctors are careful about how often they prescribe an antibiotic when treating a patient. 

Example: A patient becomes infected with strep throat. Her doctor prescribes Antibiotic X, which successfully kills off the infection. Three months later, the patient becomes infected with strep throat again. Once again, the doctor prescribes Antibiotic X, and it is successful. The following year, the patient becomes infected with strep throat again, but this time, the bacteria are no longer harmed when she takes Antibiotic X. 

Which of the following BEST describes a harmful aspect of bacteria highlighted by this example?

• After repeated bacterial infections, patients are more likely to obey their doctors’ instructions. 

  
  

• Over time, harmful bacteria can develop a resistance to a specific antibiotic.

  
  

• If a person has been infected with strep throat once, they will continue to be infected every three months.

  
  

• Antibiotics are not useful when treating bacterial infections.
