Nancy took a breath and gathered her thoughts. She imagined that passing through the gray-zone door into Level 4 was like a space walk, except that instead of going into outer space, you went into inner space, which was full of the pressure of life trying to get inside your suit. People went into Level 4 areas all the time at the Institute, particularly the civilian animal caretakers. But going into a containment zone to perform a necropsy on an animal that had died of an amplified unknown hot agent was something a little different. This was high-hazard work. –The Hot Zone, Richard Preston What is the central idea of this excerpt from The Hot Zone?
Animal necropsies are done only by trained professionals.
People go into Level 4 areas all the time at the Institute.
Entering Level 4 is like going into inner space.
Working in a containment zone is very dangerous.

D). Working in a containment zone is very dangerous.

Explanation:

The central or overarching idea that the author intends to convey through the given excerpt is that 'Working in a containment zone is fatal' as such a zone is 'full of the pressure...to get inside your suit.' The language that the author has chosen to describe the environment of the zone and the phrases like 'amplified unknown hot agent; high-hazard work' clearly substantiate this key idea that the author is highlighting. He calls it 'gray-zone' which emphasizes his idea and he also says 'people went into Level 4 which is like a spacewalk' that discloses the gravity of hazards faced by people working there. Thus, option D is the correct answer as it reveals the key idea of threats and dangers of working containment zones.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
