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:

1. Analyze Option 1: Jargon like "field space suits", "biohazard bags" is not mainly for vivid setting description. Vivid description would use more figurative or sensory language, not technical terms.
2. Analyze Option 2: Jargon doesn't prove non - fiction. Non - fiction is about factual content, not just jargon use.
3. Analyze Option 3: Technical jargon related to biological/medical/field work (like "dissection tools", "biohazard bags") makes the text seem genuine as it uses terms actual professionals in the field would use, adding authenticity.
4. Analyze Option 4: The jargon is not to prove the writer is an expert. It's to make the text's content about the biological work seem more real, not to showcase the writer's expertise.

Answer:

C. make the text seem more genuine and authentic
