Question

An excellent tool for testing a theory is:

1.more experiments
2.verifying deductive predictions
3.its compatibility to the original hypothesis
4.the theory formulated through experiment should never be retracted

Answer 1

Well, to achieve '2', you most certainly want to do '1'. If you're lucky, you get '3' in the process, but that's not always the case. The only thing that's absolutely wrong is '4'.

I think your teacher wants to read '2'. But, as stated before, you need '1', too. :-)
