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.

根据题目举个例子来看，假设一个组里面有100部国内电影及10部国外电影，这个组的合格率为90%，即这个组里的90部国内电影及9部国外电影是合格的，而另一个组里有100部国外电影及10部国内电影，这个组的合格率为10%，即这个组里的10部国外电影集1部国内电影是合格的。然后将这两个组结合来看，只有E是正确的。
B只是说了总体的数量比，并不能推算出相关比率，所以是无关选项～

其实呢 B也是能够一部分解释的

但请注意题目中有一个significant  所以只有E 是对的

我觉得B是不对的,假设国内电影共100部,国外电影共10部,再假设所有10个分类的通过率都是10%,那么入选的国内电影是10部,国外电影1部,各自的通过率还是10%,就像数学里的分子分母等比扩大一定的倍数,比率仍然是不变的,就不能解释fact 2的现象

恩 我觉得这个解释很清楚

今天做到这个题，有疑问。A、/B/C/D都排除了 但是E为什么是对的呢？在哪里可以使两个FACT都成立？当时脑袋热选了D，就是觉得E不对 排掉了..
