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?
A.In each category, the selection panel was composed of filmmakers, and some selection panels included no foreign filmmakers.

B.Significantly more domestic films than foreign films were submitted to the festival.

C.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.

D.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.

E.Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance.
答案E     我觉得E不对啊。。。题目都说了对国外的作品acceptance一样。。。为什么啊，我选的B

我也觉得是B
不过E的意思是不是80%外国作品都送到20%的high prestige组了，所以入选的数量就少，而80%的国内作品都送到80%low prestige组里了，所以入选的数量就多。但是并没有说明high prestige的组只占少数啊

排除，只有E比较符合。B是没办法证明的。

overall rate = the sum of percentage of of rate of every category

比如，令c1的rate 是0.1,是prestige的；  c2的rate是0.2，是普通的
overall rate = 0.1* (送到C1的电影占总参展电影的比例）+ 0.2*(送到C2的电影占总参展电影的比例)

overall rate of domestic > overall rate of foreign,
所以foreign电影送到C1的比例一定是低的

楼上说的很清楚哈
