Question

the suits were orange racal suits, designed for field use with airborne biological agents, and they were the same type of suit that had been used at kitum cave - in fact, some of them had come back from africa in gene johnsons trunks. the suit has a clear, soft plastic bubble for a helmet. the suit is pressurized. air pressure is supplied by an electric motor that sucks air from the outside and passes it through virus filters and then injects it into the suit. this keeps the suit under positive pressure, so that any airborne virus particles will have a hard time flowing into it. - the hot zone, richard preston read the passage. then use the drop - down menus to answer the questions. what is the central idea of the passage? the suits were first used at kitum cave. suits protect the body from the hot agent. air is supplied by a motor that provides pressure.

Explanation:

The passage describes the suits (orange Racal suits) and their features (designed for field use with airborne biological agents, pressurized, etc.). The central idea should summarize the main purpose of the suits. The first option is just a detail (where they were first used). The third option is about how air is supplied (a detail). The second option "Suits protect the body from the hot agent" aligns with the description of the suits being for field use with airborne biological agents (which can be considered as a "hot agent" in the context of the book's theme about dangerous pathogens) and the pressurized design to prevent entry of virus particles (protection).

Answer:

Suits protect the body from the hot agent.
