Answer:
To entertain readers by illustrating how dramatic the situation is.
Step-by-step explanation:
Richard Preston's book "The Hot Zone" is a harrowing detail about how the Ebola virus was detected and the efforts of scientists to get a cure. The non-fictional thriller details the events of infection and how desperate and enduring attempts were made to get a cure for the virus.
In the given excerpt from the text, the author reveals the scene where Jerry encountered "two Hazleton workers walking toward him." The information that the two men were not supposed to be in the sealed-off area left them speechless. And the sight of the men in spacesuits left the two men "astonished, ... as if they had suddenly discovered that they were standing on the moon." This scene was mainly for entertainment purposes, with the author illustrating the dramatic nature of the situation.
