Principle: A law whose purpose is to protect wild animal populations should not be enforced against those whose actions do not threaten wild animal populations. Application: Even though there is a law against capturing wild snakes, which was enacted to protect wild snake populations, snake charmers who violate this law should not be prosecuted. Which one of the following, if true, most justifies the above application of the principle? ['Snake populations are much less threatened than the populations of several other species for which capture is legal.', 'Snake charmers capture wild snakes only because they believe they would be unable to earn a living otherwise.', 'Many attempts to prosecute snake charmers under this law have failed because prosecutors lacked adequate knowledge of the procedures used to capture snakes.', 'Since there are relatively few snake charmers and they each capture relatively few snakes per year, snake charmers have a minimal effect on wild populations.']
