Question

read 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 thermometers readings are correct.
who is the primary audience?
a writer for a popular science magazine
a high school science teacher
scientists who study water quality
theoretical physicists

Explanation:

The lab report focuses on basic experimental procedures (measuring boiling point), error analysis (impurities, equipment contamination, human error), and simple improvement suggestions (sterilizing equipment, using distilled water). These elements align with high school science lab work, where teachers evaluate student reports. Popular science writers prioritize accessible storytelling, water quality scientists focus on water composition details, and theoretical physicists study abstract concepts—none match the report’s basic experimental context.
