Question

why might a scientist repeat an experiment if he/she did not make a mistake in the first one? an experiment should be repeated to
a increase income for increased work.
b prove how interesting the study was.
c ensure the results are accurate.
d eliminate steps and save time.

Explanation:

In scientific experiments, repeating an experiment helps to ensure that the results are not due to errors or chance. By repeating, a scientist can check if the same outcome occurs, which increases the reliability and accuracy of the findings. Options A (related to income - not scientific), B (proving "how interesting" is subjective in science), and D (eliminating steps without checking accuracy is not valid) are incorrect. Option C aligns with the scientific method's emphasis on accuracy through repetition.

Answer:

C. ensure the results are accurate.
