Question

read the excerpt from the hot zone. gene johnson, the ajax of this biological war, paced back and forth across the loading dock among a pile of camouflaged military trunks—his stockpile of gear from kitum cave. the trunks contained field space suits, battery packs, rubber gloves, surgical scrub suits, syringes, needles, drugs, dissection tools, flashlights, one or two human surgery packs, blunt scissors, sample bags, plastic bottles, pickling preservatives, biohazard bags marked with red flowers, and hand - pumped garden sprayers for spraying bleach on space suits and objects that needed to be decontaminated. the main purpose of the jargon in this excerpt is to

• describe the setting in vivid and accurate detail
• convince the reader that the text is nonfiction
• make the text seem more genuine and authentic
• prove that the writer is an expert on the subject

Explanation:

The jargon (e.g., "field space suits," "biohazard bags," "dissection tools") in the excerpt from The Hot Zone is used to describe the setting (a biological - warfare - related loading dock with gear from Kitum Cave) in a vivid and accurate way. The other options are incorrect: using jargon doesn't solely convince readers it's nonfiction, jargon alone doesn't make text seem more genuine (it's about accuracy of setting), and it's not to prove the writer is an expert (but to describe the setting precisely).

Answer:

A. describe the setting in vivid and accurate detail
