Questions 31-32
Political opinion and analysis outside the mainstream rarely are found on television talk shows, and it might be thought that this state of affairs is a product of the political agenda of the television stations themselves. In fact, television stations are driven by the same economic forces as sellers of more tangible goods. Because they must attempt to capture the largest possible share of the television audience for their shows, they air only those shows that will appeal to large numbers of people. As a result, political opinions and analyses aired on television talk shows are typically bland and innocuous.
31. An assumption made in the explanation offered by the author of the passage is that
(A) most television viewers cannot agree on which elements of a particular opinion or analysis are most disturbing.
(B) there are television viewers who might refuse to watch television talk shows that they knew would be controversial and disturbing.
(C) each television viewer holds some opinion that is outside the political mainstream, but those opinions are not the same for everyone.
(D) there are television shows on which economic forces have an even greater impact than they do on television talk shows.
(E) the television talk shows of different stations resemble one another in most respects.


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.

第31题 ans B , 第 38 题 ans A, 何故 ?
我觉得第31题没有隐含这样的假设
而第38题，因为UVB会破坏GENE，所以Ozone的减少才
减少A 的数量不是ㄇ?

31、有。答案：B。
  原因：Because they must attempt to capture the largest possible share of the television audience for their shows, they air only those shows that will appeal to[ large numbers of people].
也就是说，B 是这个原因 与他后面描述的结果之间的桥梁。
若disturbing的节目人们也愿意看，“受商业利益”驱使，电台的节目就不会枯燥了。

38、我是排除出来的。答案是不是无关啊。

Kilroy

31题：电视谈话节目很少播放非主流的政治内容，主要是因为经济方面的考虑，要满足大多数观众的口味。
从而推出大多数观众不喜欢非主流政治，也就是答案B
32题，刚开始我在答案A和D中犹豫，后来分析一下，觉得D是正确的：两栖类动物的减少不是因为它的栖息地减少造成的，从而支持了是由于臭氧层缺乏的原因。
而答案A只是说明了UVB是所有透过射线中的唯一对基因造成破坏的射线，对结论不构成支持

比我的清晰多了。谢谢！

谢谢!!! tongxun and Kilroy
31题我已经完全了解
而38 题 起初也在A与D 中 挣扎许久，我本来也是设想两栖类动物的减少不是因为栖息地的原因，谢谢
