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?

1. In each category, the selection panel was composed of filmmakers, and some selection panels included no foreign filmmakers.
2. Significantly more domestic films than foreign films were submitted to the festival.
3. 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.
4. 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.
5. Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance.

不知道为什么选E. 我选b. 是答案错了吗？请教思路。

E is right
Assume there are A and B categories, B is the category with low rate of acceptance.
As the subject says, most of foreign films are in B category and we assume the number to be 10, with domestic films number of 2.
While in category A, opposite, 10 domestic and 2 foreign.
what will happen?
(Acceptance rate, A 0.1, B 0.3)
You can easily find that 1.6 foreign films will be accepted and 3.2 domestic respectively.

我理解的Fact 1中的the rate of acceptance 和Fact 2中的The overall rate of acceptance 可以用如下例子：

the rate of acceptance：

                  Domestic:        Foreign:

catagory 1:   10/20             1/2

catagory 2:    20/60            1/3

只举2个。

The overall rate of acceptance：

Domestic:  10+20/20+60+2+3=6/17

Foreign: 1+1/20+60+2+3=2/85

说明了选项B是正确的吧。请给我看看对不对。

在深圳烤鸡

管卫东的题目哪里来的， 自编的还是真题？  B E都解释的通， 这题就没有实际烤得意义了

B不对

数量多不意味着通过的几率就大，如果都是垃圾片，数量再多也不会有多少会通过

E某种程度上是对FACT2的改写

FACT1是句废话，一视同仁是一句废话，意思就是只要片子好，大家都有机会通过panel

B is not right. This problem is very tricky. I bet most of the 老外 will become 头疼.

Look at : 

 Fact 2) The overall rate of acceptance of domestic films was significantly higher than that of foreign films.

then look at:  

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

It is obviously impossible to get B right when you consider that in every catergory they both have the same rate as claimed by Fact 1. If B is changed to the opposite: Less domestic films than foreign films were submitted to the festival.  Then B can be right.

This problem is just a matter of manipulating the numbers.

your example was not right b/c your acceptance rates are different in both catergories.

Look at the example below:

      Domestic: 1:   8/80            9/90         30/300

Foreign:   2:   2/20            1/10         70/700

Do the math yourself , you will see the difference.

The correct answer is E
