我選的是C..為什麼不對了..是不是又陋了哪各偵結點呢
是呀,条件1 给出的是MEMBER的拥有的东东的比率2:3:4, 他们实际拥有的数量可以是这个比例的倍数, 只要能满足a total of 18 pads, 27 pencils and 36 pads就行了. 比如说可能是3个MEMBER,每个人拥有6pads,9pencils,12pads

休息之前再给出个人意见,mm说的是可能的人数,而文中的问题是具体是多少个人(how many,而没有问possible),按照给出两者条件的结合,人数应该(1,9)之间,那么就有多种选择,你可以说只有一个成员,也可以说有9个,或者其他的,那么答案是不定的,从而只能选择E了;
謝謝,,我了解了,,,
唉,,欠缺考慮,,敗點之ㄧ
