105. A survey of alumni of the class of 1960 at Aurora University yielded puzzling results. When asked to indicate their academic rank, half of the respondents reported that they were in the top quarter of the graduating class in 1960.
Which one of the following most helps account for apparent contradiction above?
A.A disproportionately large number of high ranking alumni responded to the survey.
B.Few, if any, respondents were mistaken about their class rank.
C.Not all the alumni who were actually in the top quarter responded to the survey.
D.Almost all of the alumni who graduated in 1960 responded to the survey.
E.Academic rank at Aurora University was based on a number of considerations in addition to average grades.
the answer is A. but I choose E
我覺得E雖非完美但可解釋之間的差異 for example有些人可能在體育上較出色
有些人美術上出色 等等 因此之間的差易自然而然的消失
反觀A 雖說受訪者大部分釋high ranking 但還是無法解釋其差異
想請問大家的看法
謝謝
