Some scientists have expressed reservations about quantum theory because of its counterintuitive consequences. But despite rigorous attempts to show that quantum theory' s predictions were inaccurate, they were shown to be accurate within the generally accepted statistical margin of error. These results, which have not been equaled by quantum theory' s competitors, warrant acceptance of quantum theory. Which one of the following principles most helps to justify the reasoning above? ['A scientific theory should be accepted if it has been subjected to serious attempts to disprove it and has withstood all of them.', "The consequences of a scientific theory should not be considered counterintuitive if the theory's predictions have been found to be accurate.", 'A scientific theory should be accepted if it has fewer counterintuitive consequences than do its competitors.', 'A theory should be accepted only if its predictions have not been disproved by experiment.']
