Answer 1

When new evidence is found that contradicts part of a theory, the most appropriate response is "Science reevaluates the validity of the theory."

In scientific practice, new evidence prompts researchers to assess and test the existing theory against the new findings. This can lead to revisions of the theory, the development of new hypotheses, or, in some cases, the rejection of the theory if it is determined to be inadequate in light of the new evidence. The process is a fundamental aspect of the scientific method, which values evidence and allows for the evolution of understanding based on new data.
