标题: [求助]GWD-30-14

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.

答案e

请教

1. highlight的短语意思有什么不同？

2. 此题的解题思路应该是怎样的呢？

3. D为什么不对？

没人做这套题么？顶一下！

楼主划黄线的部份是一样的.就是"domestic film的接受比例",F1和F2不一样的地是F1是每个catalog里的,F2是overall的.

这道题是数学题,你列式子解一下能推出E是对的.

又仔细看了一下,好象是E也有问题.E说的with high prestige不理解,令外E也推不出来F1,F2.可是ABCD也都不对.D说的和fact相反.AC说的是没关的信息.B说的有可能是对也有可能不对,只有个B也是推不出F1,F2.

好象都不对.

Q32:A 再加一题：

Q32:A major chemical spill occurred five years ago at Baker’s Beach, the world’s sole nesting ground for Merrick sea turtles, and prevented nearly all the eggs laid that year from hatching. Yet the number of adult female Merricks returning to lay their eggs at Baker’s Beach has actually increased somewhat since five years ago. Clearly, environmentalists’ prediction that the world’s Merrick population would decline as a result of the spill has proven unfounded.

Which of the following, if true, most seriously undermines the argument offered in refutation of the environmentalists’ prediction?

A. A The chemical spill five years ago occurred at a time when there were neither Merrick sea turtles nor Merrick sea turtle eggs on Baker’s Beach.

B. B
Female Merrick sea turtles begin returning to Baker’s Beach to lay their eggs when they are ten years old.

C. C Under normal conditions, only a small proportion of hatchling female Merrick sea turtles survive in the ocean until adulthood and return to lay their eggs at Baker’s Beach.

D. D Environmental pressures unrelated to the chemical spill have caused a significant decline in the population of one of the several species of sea birds that prey on Merrick sea turtle eggs.

E. E After the chemical spill, an environmental group rejected a proposal to increase the Merrick sea turtle population by transferring

eggs from Baker’s Beach to nearby beaches that had not been affected by the spill.

ZL怎么理解答案b?

以下是引用cournot在2006-6-2 10:19:00的发言：

可能是本人对条件1。2理解不太清楚，能演示一下么？

F1: 就是在说每个CAT里,D和F的接受例是一样的.就是: a/b = c/d

a: D的接受的数.b:是在每一个CAT里的D的总数.

c: F的接受的数 d:是在每一个CAT里的F的总数

F2: 就是在所有的CAT里(一共10个CAT),D和F的接受例是一样的

(a1 + a2 + ....+a10 ) / (b1 + b2 +... +b10) = (c1 + .. + c10) / (d1 + ... + d10)

我是这么理解的.

作者: cournot 时间: 2006-6-2 10:49

如果是这样的话，好像B是对的，因为

category 1: Foreign domestic

submit 2 8

accept 1 4

category 2: Foreign domestic

submit 3 6

accept 1 3

每个category接受比列一样1/2=4/8，1/3=3/6；

总的接受比列：2/5<7/14,B 正确

Significantly more domestic films than foreign films were submitted to the festival.

这样解释可以么？

作者: wycg 时间: 2006-6-2 10:58

你举的例子只是一个特例,就是说可以找到一些数字让f1和f2成立.可是general来讲,B是不能推出f1和f2的.

我觉得选项都有问题.

作者: tyoi 时间: 2006-6-2 12:01

我是这样理解的

E的意思是说大部分的F都投到了接受率低的cat里，而大部分的D都投到了接受率相对高的cat里

因此总的接受率F<D

同意这么解释.

谢谢 tyoi !!!

这题关键要讲出Category之间的接受率不一样. E讲出了, B没有, 故E是答案.

比如说Drama是个比较prestige的Category, 接受10%的submission. Action是比较less prestige的Category, 接受30%. Category之间的比重不一样. 如果大量的Foreign film参加Drama, 那它的总接受率就会向10%靠近. 如果大量的American film参加Action, 它的总接受率就会向30%靠近. Category的接受率不一样 + 每Category的参加人数不一样 = 总比率不一样.

明白了，多谢指教！

the key is that the rates of acceptance in different categorys are different.

E is the key since it points out how fact2 stands there.And in my opinion ,fact 1 just says that the possiblity of the acceptence for each film is the same.Such fact eliminated a bias foundation

作者: davidli8888 时间: 2006-12-3 00:18
Thanks. The key point is that this is a math problem and you have to treat it as a math problem.

偶的看法是，fact1讲的只是一个公平的问题，也就是说当有外国的影片来参展的话，它会受到与国内影片相同的待遇，但fact2才是反映真正的情况，也就是说，虽然外国影片能受到公平对待，但他却未必会去参加所有cat的竞逐，正如E所说。

我的理解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.外国电影的接受率和国内电影的接受率不相等，但是不相等不能说明国外电影的接受率就一定小于国内的电影的接受率，所以Ｄ不对．

Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance.我觉的这局话是说外国电影和国内电影不同，外国电影和许多声誉很高的电影放在一起，这样外国电影的接受率就相对的低了．这就好比乒乓球比赛分组一样，一组里你外国队再多，有一只中国队（类比这里的with high prestige）你外国队就出不了线，何况现在的情况是一样多．所以外国电影的接受率就会小于国内电影了．

这是我的一点看法，不知道对不对．

从统计学角度，文章其实暗含了两个权重，一个是每一个CAT自己的录取率，还有是国内和国际电影各自的总数分摊到各个CAT的比率，国内和国际各自平均录取率=CAT录取率*分摊到CAT的比率，取决于两个元素同时作用，当CAT录取率相同时，分摊比率越低，平均录取率自然就低

标题: 回复：（cournot）如果是这样的话，好像B是对的，因为...

以下是引用cournot在2006-6-2 10:49:00的发言：

如果是这样的话，好像B是对的，因为

category 1: Foreign domestic

submit 2 8

accept 1 4 原文假设1，意思是每组出现名额N一定，美国片和外国片一起抢N个名额。

所以这里不是1，4！应该是N1，rate：N1/(2+8)

category 2: Foreign domestic

submit 3 6

accept 1 3

所以这里不是1，3！应该是N2，rate：N1/(3+6)

每个category接受比列一样1/2=4/8，1/3=3/6；

总的接受比列：2/5<7/14,B 正确

Significantly more domestic films than foreign films were submitted to the festival.

这样解释可以么？

所以，外国片都在出线率低的组中。

做错是这句话会错意了Within each category, the rate of acceptance for domestic films was the same as that for foreign films.
