Question

a teacher discusses a scientific theory that has been in place for almost a century. which would present the greatest challenge to this theory? lists of what the theory cannot explain discussion of the theory on internet blogs results from new experiments that contradict the theory opinions of a vocal group of citizens that oppose the theory

Explanation:

In science, empirical evidence from experiments is highly valued. New experimental results that contradict a theory directly challenge its validity as they are based on observable and testable data. Lists of what a theory can't explain are less conclusive without experimental backup. Internet blog discussions and citizens' opinions lack the scientific rigor of experimental evidence.

Answer:

C. results from new experiments that contradict the theory
