OG－9和OG－66的比较（再加OG 97）

9.

A conservation group in the United States is trying to change the long-standing image of bats as frightening creatures. The group contends that bats are feared and persecuted solely because they are shy animals that are active only at night.

Which of the following, if true, would cast the most serious doubt on the accuracy of the group’s contention?

A. Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roosting.

B. Bats are the chief consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humans.

C. Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South America.

D. Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted.

E. People know more about the behavior of other greatly feared animal species, such as lions, alligators, and greatly feared animal species, such as lions, alligators, and snakes, than they do about the behavior of bats.

答案 D

Male bowerbirds construct elaborately decorated nests, or bowers. Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds’ building styles are a culturally acquired, rather than a genetically transmitted, trait.

Which of the following, if true, would most strengthen the conclusion drawn by the researchers?

(A) There are more common characteristics than there are differences among the bower-building styles of the local bowerbird population that has been studied most extensively

(B) Young male bowerbirds are inept at bower-building and apparently spend years watching their elders before becoming accomplished in the local bower style.

(C) The bowers of one species of bowerbird lack the towers and ornamentation characteristic of the bowers of most other species of bowerbird.

(D) Bowerbirds are found only in New Guinea and Australia, where local populations of the birds apparently seldom have contact with one another.

(E) It is well known that the song dialects of some songbirds are learned rather than transmitted genetically.

答案是B  E为什么不能作答案呢？？

9的D 是类比 作为正确答案，为什么66的 E不可以？？

没有人讨论，自己顶，看看还有没有人感兴趣。。。是不是我太菜了。。

再来一个类似的疑问。。。

97.

Leaders of a miners’ union on strike against Coalco are contemplating additional measures to pressure the company to accept the union’s contract proposal. The union leaders are considering as their principal new tactic a consumer boycott against Gasco gas stations, which are owned by Energy Incorporated, the same corporation that owns Coalco.

Answer to which of the following questions is LEAST directly relevant to the union leaders’ consideration of whether attempting a boycott of Gasco will lead to acceptance of their contract proposal?

(A) Would revenue losses by Gasco seriously affect Energy Incorporated?

(B) Can current Gasco customers easily obtain gasoline elsewhere?

(C) Have other miners’ unions won contracts similar to the one proposed by this union?

(D) Have other unions that have employed a similar tactic achieved their goals with it?

(E) Do other corporations that own coal companies also own gas stations?

本题中的C.D两项，特别是D 岂不是和OG 66的E 很相似，这里OG就承认它有可能加强。。。？？？

一点个人浅见：

不管是加强还是削弱，一定要注意结论的特殊性和具体性。类比也需要紧抠结论的特殊性和具体性

OG9结论：蝙蝠让人害怕，是因为它在夜间活动。

   类比：浣熊不让人害怕，虽然它也在夜间活动。

OG97评价：矿工组织的tactic能否让其取得proposed contract?

    类比：其它组织相似的tactic和proposed contract是否成功过？

而OG66结论说的是：B鸟的建筑能力，跟S鸟的学唱歌的能力有什么关系？

请讨论。

ring_cheng 多谢回复，同意你的说法。

og-9，蝙蝠那题并不是类比。而是割断因果。原文的推理是，因为蝙蝠shy，所以被迫害。答案是，浣熊也shy，但是没有被迫害，是有因无果。所以weaken the conclusion.

og-66那题E选项完全是无关选项，原文讨论的是鸟巢的搭建能力是否是后天习得还是遗传。和song dialect没有关系。
