Answer 2

3. New advance contradicts it

Step-by-step explanation:

A theory is the result of generalized thinking about a phenomena. It is established after sufficient work has been done on a topic and the results generated are accepted by everyone specially in the scientific community. If someone disagrees with it they will need to provide evidence against it, only then can it be disproved. It does not matter if the theory is old or new, its credibility can only be judged on the basis of evidence provided against it. If there is some new advancement which contradicts an already established theory, the theory might be rejected by the scientific community. The new advancement should provide enough results against the theory.
