Question

Answer 1

The correct answer here is that if, after extensive research, the expected observations predicted by a theory fail to materialise, then the theory should be abandoned or modified. In an instance where a theory cannot be proved, it is not confirmed and is false, so none of the other possible answers for this question are true statements.
