Last year Comfort Airlines had twice as many delayed flights as the year before, but the number of complaints from passengers about delayed flights went up three times. It is unlikely that this disproportionate increase in complaints was rooted in an increase in overall dissatisfaction with the service Comfort Airlines provides, since the airline made a special effort to improve other aspects of its service last year.

Which of the following, if true, most helps to explain the disproportionate increase in customer complaints?


Comfort Airlines had more flights last year than the year before.

Last year a single period of unusually bad weather caused a large number of flights to be delayed.

Some of the improvements that Comfort Airlines made in its service were required by new government regulations.

The average length of flight delay was greater last year than it was the year before.

The average number of passengers per flight was no higher last year than the year before.

考题讲解

情景:去年,Comfort航空公司的延误航班数量是前一年的两倍,但是抱怨数却增加了3倍。这不是因为顾客整体的不满,因为去年该航空公司在很多方面的服务都提升了。

推理:请注意本题的问题,本题的问题直接问的是那个选项可以解释这个抱怨数的增加。换句话说,问题并没有让我们找推理的麻烦,而是直接找一个能解释抱怨数的变化的就行了,因此,直接看选项即可。

选题方式:略。

选项分析:

A选项:Comfort航空公司去年比之前的年份的航班数更多。航班数多少和抱怨率无关。再说,航班更多了,旅客再怎么说也只能更满意。

B选项:去年,一个段时期的严重坏天气让很多的飞机延误了。本选项解释的是为什么延误数增加,而不是解释为什么抱怨数增加比率比抱怨数更高。

C选项:有些Comfort航空公司服务的提升是被新的政策规定的。本选项和抱怨数无关。

D选项:Correct. 去年比之前的年份的延误时间增长了。
本选项解释了为什么延误数和抱怨数的增加不同步,因为,单次的延误时间加长了,以前可能延误10分钟,大家也不抱怨,但是现在每次延误1小时,那抱怨的人数自然就变多了。

E选项:去年每班飞机的旅客数量没有比之前增加。
本选项和抱怨数关系不大,至少也是可以不增加抱怨的。
