看在杰西卡头像上。。。。
我觉得目前条件下,应该是E;
有一道同样的Prep的题,提到了membership,印象很深刻,呵呵
132. 14175-!-item-!-187;#058&010326 If the drama club and music club are combined, what percent of the combined membership will be male?
(1) Of the 16 members of the drama club, 15 are male.
(2) Of the 20 members of the music club, 10 are male. 【答案】E 【思路】 (1) 只給了drama club 裡其中的會員有 16人,而這16人裡有 15人是male, 推得 1位是女的,但是沒給drama club 總共會員人數, insufficient (2)也是同樣的道理, insufficient (1)+ (2)仍然無法知道總共會員人數,無法知道percent of the combined membership will be male, insufficient |
