When a theory is challenged by new evidence, the following outcomes could occur:
A. The theory could be altered (changed) - This is a common response, as theories often evolve in light of new evidence to better explain observations.
B. The theory is accepted, not the evidence - In some cases, especially if the evidence is deemed flawed or insufficient, the existing theory might still be upheld.
C. The evidence is wrong - This outcome can happen if the new evidence is rigorously scrutinized and found to be incorrect or misinterpreted.
D. A vote is taken to accept new evidence - While this is less common in scientific practice, consensus or peer review discussions can determine how evidence is accepted within a scientific community.
Overall, A, B, and C are valid possibilities depending on the circumstances surrounding the evidence and the theory in question. D is rarer but can occur in formal settings.
