寂静一道考古题 NN们帮忙看一下

呼啸700

Recently discovered fossil evidence casts doubt on the evolutionary theory that dinosaurs are more closely related to reptiles than to other classes of animals. Fossils show that some dinosaurs had hollow bones-a feature found today only in warm blooded creatures, such as birds, that have a high metabolic rates. Dinosaurs had well-developed senses of sight and hearing, which is not true of present-day cold blooded creatures like reptiles. The highly arched mouth roof of some dinosaurs would have permitted them to breathe while eating, as fast â?“breathing animals, such as birds, need to do.Today all fast-breathing animals are warm blooded. Finally, fossils reveal that many dinosaurs had a pattern of growth typical of warm-blooded animals.


The argument in the passage proceeds by

(A)Attempting to justify one position by demonstrating that an opposition is based on erroneous information.
(B)Establishing a general principle that it then uses to draw a conclusion
about a particular case
(C)Dismissing a claim made about the present on the basis of historical
evidence
(D)Assuming that if all members of a category have a certain property then all things with that property belong to the category
(E)Presenting evidence that a past phenomenon is more similar to one than the other of two present day （答案）

这是一道LSAT题呀。。。GMAT的题是非形式逻辑的，这题明显是形式逻辑。。。
形式逻辑多简单呀，怎么说怎么来呗。。。

第一句：恐龙不更像爬行动物
第二句：恐龙骨骼更象鸟的
第三句：恐龙感官发育比爬行动物好很多
第四句：恐龙具有fast-breathing动物的特点，而现如今有这些特点的都是温血
第五句：恐龙有类似于哺乳动物的生长阶段

后面的内容就是通过提供例子说明过去的一个现象更倾向于现如今的一个嘛。。。

A：通过来例举某一个命题的否命题是错误的来证明原命题的正确。除非文章说恐龙如何如何不像冷血
B：建立一个通用的标准来得出特定的结论。典型的三段论：人都有头发，小孩儿是人 =〉小孩儿有头发。原文根本没有这样的逻辑。。。
C：基于历史证据推翻现在的预言。claim是预言的意思，所以这是数学归纳法的问题，原文没有涉及任何的归纳法
D：假定，集合中所有的元素共享某一特点，则具有特点的都在集合中。（衣服都是布做的 =〉布做的东西都是衣服）。原文没有说具有哪些特点的就一定是温血动物。。。
