单选题

【正确答案】 D
【答案解析】此题属于语意搭配题。选项[D]issue可表示“讨论话题”(a problem or subject that people discuss),例如:We should raise the issue of unemployment.issue的这个含义与下文提及的concerns were raised...(人们关注此事)互相呼应,因此是正确答案。选项[A]impact表示“冲击力”,例如:The impact broke the windows of the car.该词的含义可引申为“影响”,例如:My father has a deep impact on me.选项[B]incident表示“事件,事变”。选项[C]inference表示“推理”,例如:What inference can you draw from this passage?它们的词义都不符合文章此处的要求。
