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.

答案是A, 不是很明白,请NN帮忙解释!

有50%的调查者说他们的academic rank在前25%之内。

如果参加调查的并且回复的人绝大部分都是前25%，而其他人并没有参加或者回复，那就上述情况就可能存在了。

ls错了把，TOP15只有那么多位置，如果TOP QUARTER只是一个分数标准的话还有可能，排名的话只有15个位置，唯一一个可能就是那些人在撒谎

哈，发现自己错了，half of the respondents而不是half of the class students
