Answer:
Staging area
Supply air lock
Hot zone.
Explanation:
The term "jargon" refers to the use of certain words or phrases that is understandable only for people within that same circle. This use of vocabulary which is peculiar to a certain trade, profession, or circle is known as jargon. In short, jargons are words that we do not use in everyday conversations.
In the given excerpt, the use of jargon is seen in the phrases like "staging area", "supply air lock", "hot zone". These terms are used to refer to the particular place that will help them get to another place, the supply air lock being the pipe that supplies air into one part of the whole set-up, and the hot zone referring to the main scene or place where the experiments are done or the virus is most prominent.
Thus, the three jargons are "staging area, supply air lock, hot zone".
