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.
这道题目给的参考答案是E,但是我觉得这道题目应该选B
这应该是一道数学逻辑题目,
题目中有两个事实:1,每个分类中,本地电影和外来电影的通过率是相同的;2,所有的加起来,本地电影的通过率远远大于外来电影。
问解释。
可以这么来看,为了简单期间认为就两个分类,且设第1个分类中本地电影总数为A1,外来电影总数为B1,相应的第2个分类分别为A2和B2。
那么从事实1可以得到通过率一样,此处设为x,为了简单期间认为两个分类通过率相同。
从事实2可以得到(A1X+A2X) / (A1+A2+B1+B2) > (B1X+B2X) / (A1+A2+B1+B2),同时消掉分母,即得到A1+A2 > B1+B2,也就是B答案所描述的内容。
请讨论。 |
