Those who fear the influence of television deliberately ______ its persuasive power, hoping that they might keep knowledge of its potential to effect social change from being widely disseminated.
【正确答案】
B
【答案解析】- 方程等号：逗号说明前后句意同义重复。 - 强词和对应：根据题意，那些人希望有关电视能够潜在影响社会变革的事实不被广泛传播，空格和keep from being widely disseminated取同，体现对电视采取负动作，填一个负向词。promote促进，underplay轻描淡写，excuse辩解，laud称赞，suspect认为。答案选B。
