请教费费宝典19,38两题

Jane: Television programs and movies that depict violence among teenagers are extremely popular. Given how influential these media are, we have good reason to believe that these depictions cause young people to engage in violent behavior. Hence, depictions of violence among teenagers should be prohibited from movies and television programs, if only in those programs and movies promoted to young audiences.
Maurice: But you are recommending nothing short of censorship! Besides which, your claim that television and movie depictions of violence cause violence is mistaken: violence among young people predates movies and television by centuries.
19. Which one of the following, if true, most strengthens Jane’s argument?
(A) The most violent characters depicted in movies and on television programs are adult characters who are portrayed by adult actors.
(B) The movies that have been shown to have the most influence on young people’s behavior are those that are promoted to young audiences.
(C) The people who make the most profits in the movie and television industry are those who can successfully promote their work to both young and old audiences.
(D) Many adolescents who engage in violent behavior had already displayed such behavior before they were exposed violence in movies.
(E) Among the producers who make both movies and television programs, many voluntarily restrict the subject matter of films directed toward young audiences.

答案是B, "But you are recommending nothing short of censorship" 这句没看懂,请高人指点.

38. Amphibian populations are declining in numbers worldwide. Not coincidentally, the earth’s ozone layer has been continuously depleted throughout the last 50 years. Atmospheric ozone blocks UV-B, a type of ultraviolet radiation that is continuously produced by the sun, and which can damage genes. Because amphibians lack hair, hide, or feathers to shield them, they are particularly vulnerable to UV-B radiation. In addition, their gelatinous eggs lack the protection of leathery or hard shells. Thus, the primary cause of the declining amphibian population is the depletion of the ozone layer.
Each of the following, if true, would strengthen the argument EXCEPT:
(A) Of the various types of radiation blocked by atmospheric ozone, UV-B is the only type that can damage genes.
(B) Amphibian populations are declining far more rapidly than are the populations of nonamphibian species whose tissues and eggs have more natural protection from UV-B.
(C) Atmospheric ozone has been significantly depleted above all the areas of the world in which amphibian populations are declining.
(D) The natural habitat of amphibians has not become smaller over the past century.
(E) Amphibian populations have declined continuously for the last 50 years.

答案是A, D 为何不对?

1，意思是，你推荐的纯粹就是节目审查制度。

2，D恰恰是排除他因的加强

请问A答案是怎么不STRENTHEN 的？

我也是一样的问题，另外，E呢？E也不是加强，因为没有说明原因导致A下降。

A说的是臭氧抵挡的光线里只有UVB是伤害基因的，这一说法对结论的支持在哪里呢？当然它也没有削弱，属于无关选项
E怎么不是加强呢？它是没有直接说明结论，但它所说的情况符合结论推理出的结果，不是吗？支持并不要求说明结论，而是附和结论。

附和结论，也算加强吗？加强，一是证明结论，二是排除他因。真的没懂。再讲讲好吗？谢谢。

from the passage, we know that:

Amphibian populations are declining in numbers worldwide. Not coincidentally, the earth’s ozone layer has been continuously depleted throughout the last 50 years.

lack of information about how long Amphibian population has been declining, we will a risky conclusion on the relation between .... and .... Therefore, choice E provide addtional information to support the conclusion..

albert,

do you think that how long A population has been declining is relevant to the argument ? If we say A population has been deceling for one year , it is also consistent with the argument .So i think it is irrevelant .

since the passage try to establish a connection between the declination of Amphbian and the deplete of the earth’s ozone layer , therefore the period of such two event should be the same..in passage we know the the earth’s ozone layer has been depleting for 50 years..if as you said, the population of amphbian has been declining for only one year, the conclusion will be weaken because it is cutting the relation given to the discrepancy of the period of two events..

so it is pretty important to notice some discrepancy of two events..

good luck!

albert, i eventually got it now. Thank u very much.
