Question

review the lab report conclusion and then answer the question.

based on the data gathered, we measured the boiling point of water as 99.51 degrees celsius. the error against the expected measurement was 0.49 percent. sources of error may have been impurities in the water, contamination of the equipment, or human error in reading the thermometer. if we repeated the experiment, we might achieve more accurate results by sterilizing our equipment, using distilled water, and verifying that the thermometer’s readings are correct.

which best indicates that the primary audience is a high school science teacher?

the writer uses language and jargon that only teachers would understand.

the writer describes the experiments methodology in detail.

the writer describes a simple experiment with a known outcome.

the writer uses the pronoun we but doesnt directly address the audience.

Explanation:

The question asks which option best indicates the primary audience is a high school science teacher. Let’s analyze each option:

1. "The writer uses language and jargon that only teachers would understand" is incorrect—high school science experiments use basic terms accessible to students, not exclusive teacher jargon.
2. "The writer describes the experiment's methodology in detail" is not supported—no detailed methodology is provided in the conclusion.
3. "The writer describes a simple experiment with a known outcome" is correct: measuring water’s boiling point is a standard high school experiment with an expected result (100°C), which aligns with what a teacher would assess.
4. "The writer uses the pronoun we but doesn't directly address the audience" is irrelevant—"we" refers to the experimenters, not the audience.

Answer:

The writer describes a simple experiment with a known outcome.
