Question

review the water quality report and then answer the question.
springfields drinking water comes from the vance river. the watershed begins on the slopes of mount eagle
and flows nearly eighty - five miles from the rivers headwaters. naturally occurring fluoride in the vance river is
less than 0.5 ppm (parts per million), which is the detection limit for analyzing fluoride. the water is made safe
to drink through conventional treatment methods and consistent monitoring.
which best indicates that the primary audience is residents of springfield?
the writer defines unfamiliar terms (ppm) and informs
readers that the water is safe.
the writer tries to make springfields water sound appealing.
the writer uses the technical abbreviation ppm and notes the
detection limit for analyzing fluoride.
the writer specifies that the vance river flows down the
slopes of mount eagle.

Explanation:

When the primary audience is residents of Springfield, the writer would define unfamiliar terms (like ppm) and inform them about water safety. This helps the general - public (residents) understand the information. Making the water sound appealing might be a secondary aspect. Using a technical abbreviation without proper explanation (if the audience is non - technical residents) would be less likely. Specifying the river's origin (slopes of Mount Eagle) is more of a descriptive fact rather than something specifically tailored for residents' understanding of their water supply.

Answer:

The writer defines unfamiliar terms (ppm) and informs readers that the water is safe.
