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.






正确答案是E。
但有两句话不太理解，麻烦帮忙看一下。谢谢。
rate of acceptance for dmoestic films= (该category中通过的国产电影数量)除以(该category中提交的国产电影数量)  ?
overall rate of acceptance of domestic films =  (所有category中通过的国产电影数量)除以(所有category中提交的国产电影数量)  ?
为什么overall rate of acceptance of domestic films 不是 (所有category中通过的国产电影数量)除以(所有category中提交的国产和国外电影数量)?
rate of 后面 一个用了for，一个用了of

我在做这道题的时候就蒙了，这些rate到底是谁除以谁啊。搞不清楚啊。

我现在知道the rate of A for B 或者 the rate of A of B的含义了，其实一样。
都是指A在B中所占的比例

这里有解释
Assume catoegory X has acceptance rate of 1 out of 5

Assume catoegory Y has acceptance rate of 3 out of 5

Since foreign films were submitted only to X, it's acceptance rate is 1/5

Sinnce domestic films were submitted to both the catoegories, it's acceptance rate is 4/10 1.e. 2/5
补充一点，电影节的评奖项目有很多，比如最佳导演奖，最佳女主角奖，这些都是单个奖项。也就是Fact 1里面所说的。然后把这些总奖项相加，就是Fact 2里所说的。
