Which of the following is a characteristic of all good scientific hypotheses?
They are all proven to be true.
They are always formed after the experiments have been run so that they are based on as much evidence as possible.
They can all be proven true (some may end up being false but they are still good scientific hypotheses if they have the
possibility of being proven true).
They are all falsifiable (some are hopefully true but the possibility that they can be shown to be wrong makes them good
scientific hypotheses).
