Linguist: The Sapir-Whorf hypothesis states that a society' s world view is influenced by the language or languages its members speak. But this hypothesis does not have the verifiability of hypotheses of physical science, since it is not clear that the hypothesis could be tested. If the linguist's statements are accurate, which one of the following is most supported by them? ['Only verifiable hypotheses should be seriously considered.', 'Only the hypotheses of physical science should be taken seriously.', 'Only the hypotheses of physical science are verifiable.', 'We do not know whether the Sapir-Whorf hypothesis is true or false.']
