Question

review the water quality report and then answer the question.
westminsters drinking water comes from the yamada 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 yamada 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 westminster?
the writer uses the technical abbreviation ppm and notes the detection limit for analyzing fluoride.
the writer tries to make westminsters water sound appealing.
the writer defines unfamiliar terms (ppm) and informs readers that the water is safe.
the writer specifies that the yamada river flows down the slopes of mount eagle.

Explanation:

The question asks which option indicates the primary audience is Westminster residents. Residents need clear, accessible info about their drinking water safety. Defining unfamiliar terms (ppm) ensures understanding, and stating the water is safe directly addresses their concern about drinking water quality. Other options don’t target residents: technical details without context (first option) or irrelevant descriptions (fourth) don’t prioritize resident needs; making water sound appealing (second) isn’t the main goal of a safety report.

Answer:

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