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? 

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.

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？

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.

thank you!

还是不懂，请教可以讲的具体点么？

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.

可能是本人对条件1。2理解不太清楚，能演示一下么？

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?

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.

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？
