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.
和本国片不同，大部分外国片都被分在了高档，但是通过率很低的类别【10个类别，每个类别的通过率未必相同的。在我们假设B选项的时候其实就应该想到了。可能有几个类别，外国通过率和本国通过率都很低。如果大部分外国片集中在这样的category里面，那么显然被选中的片子就很少，总通过率就很低。可以用“加权”的思想考虑】
想这么一个问题，over all acceptance rate是怎么来的
应该是通过的片子数量/投送的片子总量
B说两个分数的分母有大小关系，但分母有大小关系不能代表两个分数值也有大小关系 所以B不对
A错在哪里？
不同类别的通过率不一样，所以就算对国内和外国片一视同仁，但有些类别就是通过率低一些，而外国片大部分去了这种类别
事实1：每一个类别下，国产片的通过率等于外语片；
事实2：总体，国产片的通过率高于外语片。
为啥呢？因为某一个大类下聚集了很多外语片，而那个大类下的外语片的通过率很低。所以选E。
'E' says MOST F were submitted in CATEGORIES with low rates
that's the category which has low rate of acceptance,NOT F has the low rate of acceptance.
