True or False: Antibiotics work by introducing an agent that resembles a disease-causing microbe, thus stimulating the body's immune system to recognize it as foreign, destroy it, and "remember" it, so that it can more easily identify and destroy any similar, disease-causing microbes that it later encounters.

Sorry, that’s incorrect.
The above describes how vaccines work. Antibiotics work by either killing bacteria or stopping them from reproducing, allowing the body's natural defenses to eliminate the pathogens.

“Antibiotic resistance” refers to:
- The reluctance of physicians to prescribe antibiotics
- An underground movement against pharmaceutical companies
- The ability of bacteria to resist the effects of an antibiotic
-
Sorry, that’s incorrect.
“Antibiotic resistance” refers to the ability of bacteria to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria undergo a genetic change that reduces or eliminates the effectiveness of drugs or other agents designed to cure or prevent infection.

Which of the following diseases kills more children worldwide than any other infectious disease?
- Lower respiratory tract infections (including pneumonia)
- HIV/AIDS
- Diarrheal diseases
- Tuberculosis
- Malaria
