Answer:
Working in a containment zone is very dangerous.
Step-by-step explanation:
In the excerpt from "The Hot Zone," by Richard Preston, Dr Nancy Jaax is given a promotion to carry out research on Ebola at a medical institute. In that respect, working at the containment zone is extremely hazardous, since scientists are exposed to extremely infectious diseases from animals that come from hot tropical places. In fact, she is almost contaminated with the Ebola virus.
