Which statement is the best summary of the central
idea of this passage?
"Looks like we have some sick monkeys in here," he said.
Some of the monkeys went berserk when they saw the
space suits. They spun in circles in their cages or cowered
in the corners. Others stared at the humans with fixed
expressions on their faces.
"You see the clinical signs," Dalgard said, pointing to a
monkey. "I feel pretty confident I can tell when a monkey
is getting sick. They get a little bit depressed, they go off
their feed, and in a day or two they are dead."
-The Hot Zone,

illness in the monkeys.
The monkeys go berserk, stare with fixed
expressions, and stop eating,
The monkeys are afraid of the men in space suits,
The monkeys do not show any signs of clinical
depression or illness,
