Question

what do they do?
in the video we heard what epidemiologists do.
which words best complete the sentence?
they look for ______ of disease in human populations
and develop ways to ____ and ____ outbreaks.

○ patterns; increase; spread
○ symptoms; control; prevent
○ symptoms; decrease; control
○ patterns; prevent; control

Explanation:

Epidemiologists study disease distribution in populations. They look for "patterns" (not symptoms, as symptoms are individual - level) of disease. Their goal is to "prevent" and "control" outbreaks (not increase/spread, and "prevent" comes before "control" in logical order for outbreak management). So the correct option is the one with patterns, prevent, control.

Answer:

patterns; prevent; control (the option with "patterns; prevent; control" as the three words to fill in the blanks)
