单选题 Man: Excuse me. Do you need some help?
Women: Well... I"m trying to get to the railway station, but I can"t make heads or tails of this ticket machine.
Question: What is the women"s problem?

A、 She doesn"t have the small change with her
B、 She doesn"t know how to use the machine
C、 She"s not sure how much the trip will cost
D、 She"s unable to get the ticket in time

【正确答案】 B

【答案解析】[解析] 句型can"t make heads or tails of something是用来描述对一件事从头到尾都一头雾水，也就是中文常说的丈二和尚摸不着头脑，搞不清楚到底是怎么回事。所以可以推知女士的麻烦是她不知道怎么用售票机。故答案为B。
