Question 1: What historical milestone was Antoni van Leeuwenhoek the first
person to achieve?
A. Disinfecting surgical instruments with carbolic acid
B. Tracing a cholera outbreak to a public water pump
C. Viewing protozoa and bacteria, which he termed "animalcules"
D. Proving the germ theory of disease using swan-neck flasks
✔✔ Correct Answer: C (Using his handmade single-lens microscopes,
Leeuwenhoek was the first to observe and document microscopic single-celled
life).
Question 2: Who is credited with developing the technique of vaccination to
prevent smallpox?
A. Louis Pasteur
B. Robert Koch
C. Edward Jenner
D. Ignaz Semmelweis
✔✔ Correct Answer: C (Jenner successfully utilized cowpox inoculation to
confer immunity against smallpox in 1796).
Question 3: Which historical figure heavily advocated for handwashing with
chlorinated lime among medical personnel to dramatically reduce mortality
from puerperal sepsis (childbed fever)?
A. John Snow
B. Alexander Fleming
C. Ignaz Semmelweis
, D. Joseph Lister
✔✔ Correct Answer: C (Semmelweis instituted mandatory handwashing
protocols in maternity clinics, observing a sharp drop in postpartum infections).
Question 4: Who is widely recognized for foundational contributions to
modern epidemiology and infection control through tracing a London cholera
epidemic?
A. Robert Hooke
B. John Snow
C. Anton van Leeuwenhoek
D. Edward Jenner
✔✔ Correct Answer: B (Snow mapped cholera cases during the 1854 Broad
Street outbreak, establishing key methods of epidemiological investigation).
Question 5: Which scientist definitively disproved the theory of spontaneous
generation using ingenious swan-neck flask experiments?
A. Francesco Redi
B. Louis Pasteur
C. John Needham
D. Lazzaro Spallanzani
✔✔ Correct Answer: B (Pasteur's swan-neck flasks allowed air to enter while
trapping airborne microbes, proving that sterile broths remained free of life unless
exposed to pre-existing microorganisms).
Robert Koch was involved in research on all of the following topics except...
A) the cause of anthrax.
B) the cause of fermentation.
C) development of a method to prove the cause of an infectious disease.
