A poor farmer was fond of telling his children: "In this world, you are either rich or poor, and you are either honest or dishonest. All poor farmers are honest. Ttherefore, all rich farmers are dishonest. " The farmer's conclusion is properly drawn if the argument assumes that ['everyone who is poor is honest', 'every honest farmer is poor', 'everyone who is dishonest is a rich farmer', 'every honest person is a farmer']
