11、虎鲸和sea otter
pipopipo0939提供
GWD-8-Q3:
In the late 1980’s, the population of sea otters in the North Pacific Ocean began to decline. Of the two plausible explanations for the decline—increased predation by killer whales or disease—disease is the more likely. After all, a concurrent sharp decline in the populations of seals and sea lions was almost certainly caused by a pollution-related disease, which could have spread to sea otters, whereas the population of killer whales did not change noticeably.
Which of the following, if true, most seriously weakens the reasoning?
A. Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey.---正解
B. There is no indication that substantial numbers of sea otters migrated to other locations from the North Pacific in the 1980’s.
C. Along the Pacific coast of North America in the 1980’s, sea otters were absent from many locations where they had been relatively common in former times.
D. Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters’ main food source.
E. The North Pacific populations of seals and sea lions cover a wider geographic area than does the population of sea otters.

06年变体版本:有一个 sea otter (不知道是不是这么写)和 whale killer 的题,不过题目和原来不一样,没有说 disease ,而且选项也变了
个大家注意题目变体
12、菜农对付超市低价
V1 from koncat
某地菜农因为某种作物被大供应商在超市里压低了价格所以决定独辟蹊径开始种植另一种作物。然后问evaluate.这题我不很确定,选的是该种菜在另一个地方超市的供应价格。。。唉现在看来好像不对,但是当时我觉得这个貌似是最优选。。其他更不靠谱。。
V2 Lovepova补充选项:农民另辟蹊径种新产品, 那题我选的 whether they can market the new product without relying on supermarket
个人倾向V2选项…
13、蜜蜂认人脸
V1 from koncat
是蜜蜂会认人脸的,时间不够了没仔细看题,说是挂两张画,年轻微笑的人与甜罐头在一起,年老的人与苦罐头在一起(这个我不知道怎么复述),结果最后蜜蜂都跑到年轻微笑的人那里去了。说明蜜蜂会认人脸。问这个结论成立必须建立在什么条件上。我选的是把甜罐头换成普通罐头(还是苦罐头?)也会不会有不同...
14、怀疑明星是否用广告中的产品
V1 from beckwang1983
人们对广告中明星是否真的使用这一产品表示怀疑,所以现在拍广告不应该继续请明星。问削弱。
考古:
06年版本:某学者认为用明星代言广告没效果,因为调查显示人们都不相信明星真会用这些滥产品。问 weaken ,我选 “ 人们对明星比较能记住 ” ,这题没把握,感觉这也 weaken 不了,但其他选项更不相关
现在人们都不信电视里的广告了,举例说,最近的调查显示观众很少相信明星做广告,明星就用这个产品。问,下列哪个能 weak 这个举出的例子。我选的是,现在人,对于报纸,广播,电视都不信。(前人有选,名人广告,能吸引观众。) 答案不统一,慎重参考!
感谢amumu给出猜测 削弱:
1、统一比较的水平线:不用明星,人们也会怀疑
2、衡量是否找明星有很多原因,人们是否怀疑只是一个考虑因素。 |
