B. Newspapers in the early United States normally declared quite openly their refusal to tell all sides of most political stories.
C. The editorial policies of some early United States newspapers became a counterweight to proponents of traditional values.
仍然是多项选择题，要求考生自主列出ABC正确的组合。正确答案为C。A选项极具干扰度，文首谈到的一种报纸变化乃是一种未来的趋势。而A项做出了美国GRE阅读中很敏感的比较(than)，原文没有明确的关于现在报纸的风格比较。B项为文中让步层面内容：even when editors disingenuously stated that they aimed to tell all sides of a story，体会该叙述，与公开声明的程度不符。C项counterweight解释为平衡物，表达了文末关于一些支持republican编辑的态度。
