W: Thank heavens! You're back safe and sound. Everyone was worried on hearing about the air crash. And I had so many sleepless nights!
M: Yes, I know your feeling, dear! Even I myself don't know how I escaped it. I was the only lucky guy.
Q: What do we learn from the conversation?
解析：第一个人提到air crash，第二个人提到the only lucky guy，综合得出A。C过于以偏概全（不能因为一次幸运就说他总是幸运）；D错在a few，实际上此次空难中男士是唯一的幸存者。
M: Well, I just wonder who puts the candies into the boxes?
W: It is done by a machine, which is able to count the candies automatically. Please, this way. I'll show you right away.
Q: Where does this conversation probably take place?
