A study of ticket sales at a summer theater festival found that people who bought
tickets to individual plays had a no-show rate of less than 1 percent, while those
who paid in advance for all ten plays being performed that summer had a no-show
rate of nearly 30 percent. This may be at least in part because the greater the
awareness customers retain about the cost of an item, the more likely they are to
use it.
Which of the following would, if true, best serve as an alternative explanation of
the results of the study?
(A) The price per ticket was slightly cheaper for those who bought all ten
tickets in advance.
(B) Many people who attended the theater festival believed strongly that
they should support it financially.
(C) Those who attended all ten plays became eligible for a partial refund.
(D) Usually, people who bought tickets to individual plays did so
immediately prior to each performance that they attended.
(E) People who arrived just before the performance began could not be
assured of obtaining seats in a preferred location.


C为什么不可以？我觉得可以要求退款完全可以成为另外一个explanation啊？

如果十场都参加可以refund一部分，大家就会更多的参加，attendence rate会高才对。
答案是D吗？

注意C的条件，只有attended all ten plays的人才能得到一些退款。你少一场没去都没法有退款呀，那大家为了退款也会都去的
