问题 From the text we can infer that the NAB represents______.
The foremost motivation behind the low-power radio initiative was to______.

选项 A、increase competition on the airwaves
B、counter the effects of prior legislation
C、increase local programming in urban areas
D、encourage community involvement in radio broadcasting

答案B

解析 细节分析。题目中的关键词foremost motivation 出现在最后一段第一句,其中foremost 是原文primary的同义词:向低功率无线广播开放电波的主要动机是为了消除1996年的《电信条例》造成的损害。由此可知,选项B符合句意,其中counter the effects 是原文 undo the damage 的同义表达。选项A与本段第二句意义不符,注意句中的supposed to...(本应该…,人们期望…)以及下句中的instead (相反)说明了事实正相反。选项C、D的内容包括在选项B中(见本段第二句最后一部分和第四句)。
