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 phrase "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" best indicates that the primary audience is a high school science teacher. High school science teachers are often responsible for instructing students on proper experimental procedures and techniques to improve accuracy in scientific measurements.
