C.

Check if the experiment gives the same results when it is repeated.



D.

See which theory does a better job of explaining the results of the experiment.

Verified Answer :

I think the answer is C, because repeating an experiment would mean the result is more accurate when done more then once. i learned this in around 7th grade, I hope it helps! (:

Answer:

The correct answer is option D. "See which theory does a better job of explaining the results of the experiment".

Explanation:

A theory is a well established supposition that explains a phenomenon observed in nature or in laboratory based on proved principles. A scientist could compare theories by doing an experiment to see which theory does a better job of explaining the results of the experiment. This helps to see which theory is accurate and getting closer to get a definitive explanation to the observed phenomenon.
