Answer
A
A new, untested hypothesis is proposed.
B
New information is discovered that does not support the theory.
C
A single experiment produces results that differ from all previous experiments.
D
New technology is developed that provides more information about the theory.
E
New experimental methods are designed to test a theory.
Explanation
A theory may be revised or replaced when reliable new evidence does not support it. New technology and improved experimental methods can provide better ways to investigate a theory and may reveal evidence that calls for a change. A new, untested hypothesis alone is not evidence against an existing theory, and one experiment with an unusual result should be checked before changing a theory.
