Political scientist: While voters have a legal right to know what is being done by those whom they elect, there must be limits placed on public access to the detailed workings of the legislative process. Legislators receive little credit for reaching compromises but much criticism for failing to stick to their principles, and thus become less willing to modify their demands so that needed legislation can be passed. Which one of the following principles, if valid, would most help to justify the political scientist's reasoning? ['It is acceptable to restrict some legal rights if doing so makes the political process more efficient.', 'Legislators should be given credit for reaching compromises that facilitate the passage of needed legislation.', 'Compromise between factions with equally compelling interests can only be effected by unprincipled legislators.', 'Legislation should be written so as to benefit the welfare of all citizens, rather than only a few.']
