单选题 Which of the following statements is true with regard to the Houston Airport experiment?

A、 Professor Richard Larson hates queuing so much that he tears his hair out.
B、 According to Larson' s study, the long waiting was the cause of annoyance.
C、 When all the travelers had to wait for 2 minutes, there were a lot of complaints.
D、 When the walking time was extended to 6 minutes, there were hardly any complaints.

【正确答案】 D

【答案解析】[解析] 原文是说Professor Richard Larson hates queuing but rather than tear his hair out，而不是Professor Richard Larson hates queuing so much that he tears his hair out．因此A是错的，在上面一句话中tear one’s hair out意思是“悲伤或愤怒时举动狂野”。B的错误也很明显，原文说the degree of annoyance was not directly related to the time，所以不能说人们不满的原因是长时间的等待。C错误，原文说当从飞机到行李认领处的路程被延长至6分钟时需要认领行李的人只要比提手提行李的人多耽误两分钟的时候，passenger complaints dropped almost to zero，而不是a lot of complaints。同样，上面这一段文字也说明了答案D的正确性。
