单选题 Woman: I heard there was a terrible mine accident. They didn't want anyone to know. Man: I think it is impossible to black out this news. Question: What does the man mean?

A、 It is impossible to keep it out.
B、 It is impossible to know it.
C、 It is unlikely to prevent it from being known.
D、 It is unlikely to stop spreading the news.

【正确答案】 C

【答案解析】[解析] 女士：我听说发生了一场严重的煤矿事故，他们想隐瞒这个消息。男士：我认为这件事情不可能会一直密不透风。这里考查了对短语“black out”的理解，意为“隔绝，中断”。“black out news”意思是“封锁消息”。所以这里C选项所表达的内容与该短语内在含义一致。所以C选项是正确答案。
