Correct answers:
- when a new hypothesis provides a better explanation
- after a large amount of data refutes it

Explanation: scientific theories are provisional and are revised when better explanations or reproducible, substantial evidence contradict their predictions. A single anomalous experiment typically prompts further testing and replication rather than immediate abandonment of a theory, and a theory is not fixed once published.
