Question

review the water quality report and then answer the question.
sparrowtowns drinking water comes from the sweeney river. the watershed begins on
the slopes of mount eagle and flows nearly eighty - five miles from the river’s headwaters.
naturally occurring fluoride in the sweeney 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 sparrowtown?
the writer specifies that the sweeney river flows down the slopes of mount
eagle.
the writer uses the technical abbreviation ppm and notes the detection limit
for analyzing fluoride.
the writer defines unfamiliar terms (ppm) and informs readers that the water
is safe.
the writer tries to make sparrowtowns water sound appealing.

Explanation:

To determine the primary audience is residents, we analyze each option:

• The first option about the river's flow location is just descriptive, not audience - focused.
• The second option using technical jargon (ppm) without explanation would not be for a general resident audience.
• The third option: Defining "ppm" (an unfamiliar term for non - experts) and informing about water safety is suitable for residents (who are non - technical in water analysis) as it makes the information accessible and addresses their concern about drinking water safety.
• The fourth option about making water sound appealing is more about marketing, not indicating resident audience.

Answer:

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