In a democratic society, when a political interest group exceeds a certain size, the diverse and sometimes conflicting economic interests that can be found in almost any large group of people tend to surface. Once these conflicting interests have surfaced, they can make it impossible for the political interest group to unite behind a common program. Yet to have the political impact necessary to influence legislation, a group must be united. The statements above, if true, most strongly support which one of the following views? ['A political interest group can become ineffective by expanding to include as wide a membership as possible.', 'Political interest groups generally start out effectively but lose their effectiveness over time.', 'For a democratic society to function effectively, it is necessary for political groups within that society to make compromises with each other.', 'Political interest groups are generally less influential when their membership is expanding than when it is numerically stable.']
