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.
答案是E，但我觉得E引入了一个high prestige,这个并不能解释为什么在each category时，国产和外国片的rate相同，因为题中并没给出high prestige 等于acceptance in each category？

各组里的acceptence情况：
An为第n组的acceptance rate

                     国内                     国外
                 总     入选         总         入选
1             X1       A1X1      Y1         A1Y1
2             X2       A2X2      Y2         A2Y2
3             ...
4

10          X10      A10X10   Y10      A10Y10

总的acceptance rate：国内=(A1X1+……+A10X10)/(X1+……+X10)
                                  国外=(A1Y1+……+A10Y10)/(Y1+……+Y10)
                                  且国内>国外

如果A1=A2=……=A10相等，那必有国外=国内

现在国内>国外，那么A1……A10肯定不是全部相等的。

E指出，在high prestige组里面，acceptance rate更高，就是说A1……A10不是全部相等的，正确

其实就是F电影被送到通过率低的那些组去了，倒霉就过不了~
