Essayist: It is much less difficult to live an enjoyable life if one is able to make lifestyle choices that accord with one' s personal beliefs and then see those choices accepted by others. It is possible for people to find this kind of acceptance by choosing friends and associates who share many of their personal beliefs. Thus, no one should be denied the freedom to choose the people with whom he or she will associate. Which one of the following principles, if valid, most helps to justify the essayist's argument? ['One may choose for oneself the people with whom one will associate, if doing so could make it easier to live an enjoyable life.', 'No one should be denied the freedom to make lifestyle choices that accord with his or her personal beliefs.', 'If having a given freedom could make it less difficult for someone to live an enjoyable life, then no one should be denied that freedom.', 'No one whose enjoyment of life depends, at least in part, on friends and associates who share many of the same personal beliefs should be deliberately prevented from having such friends and associates.']
