Question

Select all that apply.
If, after extensive research, the expected observations predicted by a theory fail to materialize, then the theory
is confirmed
is probably false
should be abandoned or modified
should never be retracted

Answer 1

B. Is probably false

C. Should be abandoned or modified

Explanation - A hypothesis is given once the question is identified and background research has been done. A hypothesis is validated by performing experiments. Prior to the experiments being performed, proper planning is done.

After the experiment is carried out, the data is noted. Once the data is noted, results are inferred. If the result fails to validate the theory then the given theory is either for or need to be abandoned or modified.
