Question

read the excerpt from the hot zone.
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 central idea of this excerpt is that working in a containment zone is very dangerous. which phrases from the excerpt most support the central idea?

• amplified unknown hot agent; high-hazard work
• like a space walk; trying to get inside your suit
• going into a containment zone; perform a necropsy
• imagined that passing; civilian animal caretakers

Explanation:

The central idea is that containment zone work is dangerous. The phrase "amplified unknown hot agent; high-hazard work" directly references the extreme danger of the agent and explicitly labels the work as high-hazard, which aligns perfectly with the central idea. The other options either describe routine actions or sensory details that do not directly emphasize danger.

Answer:

amplified unknown hot agent; high-hazard work
