标题: 关于JJ和GWD里面的一题
GWD-30-Q14

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.

大家帮忙看看为什么选E啊? 我怎么也想不通,不是factor1里面已经说是rate一样了么?

收到短信了...举个最简单的例子吧...

从概率的角度来讲, 如果你参加一个10组, 一组10人的跨栏比赛. 那么理论上来说,你们每个人夺得第一名的几率全部都是1%, 你在每组胜出的几率是10%....,这就好比Fact1提供的事实.

如果你选第一组, 所有人都是CD上考GMAT的XDJM, 那你们每个人得第一得几率仍然是1%, 因为你组内胜出得几率还是10%...

如果你选第三组,所有人除了你之外,都是参加奥运会的,比如刘翔也在里头,那么从概率的角度来讲,刘翔100%获胜,相对的,你获胜的几率就小于10%啦...

放到题目中也是, 外国电影可能全部都选择了第三组这样的组别,而不是如国内电影选择第一组这种组别.
