The correct answer is C. New experiments can affect previous scientific explanations.
Explanation: An experiment is a way of checking a phenomenon under specific conditions to analyze its effects or to verify a hypothesis. An example of this is the statement because before the seventies it was believed that new neurons could not be generated in an adult brain, however, after conducting an experiment on songbirds it was found that it was possible. Therefore, it confirms that new experiments can affect previous scientific explanations because new experiments can test hypotheses that modify previous explanations. So the correct answer is C. New experiments can affect previous scientific explanations.
