Background information:  This year, each film submitted to the Barbizon Film Festival was submitted in one of ten categories.  For each category, there was a panel that decided which submitted films to accept.

Fact 1:  Within each category, the rate of acceptance for domestic films was the same as that for foreign films.

Fact 2:  The overall rate of acceptance of domestic films was significantly higher than that of foreign films.

In light of the background information, which of the following, if true, can account for fact 1 and fact 2 both being true of the submissions to this year's Barbizon Film Festival?


In each category, the selection panel was composed of filmmakers, and some selection panels included no foreign filmmakers.
Significantly more domestic films than foreign films were submitted to the festival.
In each of the past three years, the overall acceptance rate was higher for foreign than for domestic films, an outcome that had upset some domestic filmmakers.
The number of films to be selected in each category was predetermined, but in no category was it required that the acceptance rate of foreign films should equal that of domestic films.
Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance.
就剩BE,选E
我把我整理的思路贴出来
A.       In each category, the selection panel was composed of filmmakers, and some selection panels included no foreign filmmakers.陪审团怎么组成的。第一个事实就会不成立。如果评审团由不同比例的中外专家组成,那就可能不好同等接受率
B.       更多国产电影去了电影节。假设国产电影去了100个,国外电影去了80个
一种接受率0.1,一种0.5,现在不知道国产电影和国外电影各去了每组多少个,不能得出总接受率
而且一直没说过数量的问题,只出现过each category,acceptance rate, overall rate of acceptance
C.       Significantly more domestic films than foreign films were submitted to the festival.过去3年如何,和现在无关
D.      数量事前决定,但没要求接受率一样。无关选项
E.       Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance. 很多外国电影都去那些低接受率的类型里了。
也就是说,如果有2类,一类0.1接受率,但另一类接受率0.5
100个外国电影都去了0.1里面,10个外国电影去了0.5,总接受率=(10+5)/110=15/110
60个国产电影去了0.1, 50个国产电影去了0.5,总接受率=(6+25)/110=31/110
满足F1,都在一个类别里面,国产和国外电影都服从0.1的接受率
但是类别与类别之间,大的接受率又不同,分接受率高的和接受率低的
满足F2,国产的总接受率>国外的总接受率

这是后来想明白的,费好大劲,但是在考试的时候我也不可能去举一个例子去推翻B,承认E啊,考试时候哪里想得到那么多啊T^T,怎样秒选啊????
