请教LSAT-4-I-7,9
Two paleontologists, Dr Tyson and Dr. Rees, disagree over the interpretation of certain footprints that were left among other footprints in hardened volcanic ash at site G. Dr. Tyson claims they are clearly early hominid footprints since they show human characteristics: a squarish heel and a big toe immediately adjacent to the next toe. However, since the footprints indicate that if hominids made those prints they would have had to walk in an unexpected cross-stepping manner, by placing the left foot to the right of the right foot. Dr. Rees rejects Dr. Tyson's conclusion.

7. The disagreement between the two paleontologists is over which one of the following?

(A) the relative significance of various aspects of the evidence

(B) the assumption that early hominid footprints are distinguishable from other footprints

(C) the possibility of using the evidence of footprints to determine the gait of the creature that made those footprints

(D) the assumption that evidence from one paleontologic site is enough to support a conclusion

(E) the likelihood that early hominids would have walked upright on two feet

答案：A，我选了C。

最近做LSAT题，发现这种纯逻辑题反而做不好。本来不应是难题的。主要原因是经常有两个选项区别不清，做到最后，感觉是要再对应原文，再仔细区分两个选项。不知有没有什么好办法 ？

9. It is not known whether bovine spongiform encephalopathy (BSE), a disease of cattle invariably deadly to them, can be transmitted directly from one infected animal to another at all stages of the infection. If it can be, there is now a reservoir of infected cattle incubating the disease. There are no diagnostic tests to identify infected animals before the animals show overt symptoms. Therefore, if such direct transmission occurs, the disease cannot be eradicated by ____

Which one of the following best completes the argument?

(A) removing from the herd and destroying any diseased animal as soon as it shows the typical symptoms of advanced BSE

(B) developing a drug that kills the agent that cause BSE, and then treating with that drug all cattle that might have the disease

(C) destroying all cattle in areas where BSE occurs and raising cattle only in areas to which BSE is known not to have spread

(D) developing a vaccine that confers lifelong immunity against BSE and giving it to all cattle, destroying in due course all those animals for which the vaccine protection came too late

(E) developing a diagnostic test that does identify any infected animal and destroying all animals found to be infected

答案：A，我选 了C。
这种完成句子 题，我花的时间特别长，还做不好。总感觉没有把握。有什么好办法吗？

谢谢。

我觉得句子完成题有点像 RC中的main idea题，如果问的是conclusion就得回原文找，看哪个答案有原文evidence支持或者答案是否涵盖了原文中所说的意思。另外，往往紧挨着therefore,thus之前的那个句子比较重要。
以第9题为例，There are no diagnostic tests  ==> disease cannot be eradicated
问题就是要你解释diagnostic tests的作用；显然diagonostic tests的作用不是destroying all cattle(C),也不是developing a vaccine(D) or drug(B).

  另外，crack the LSAT中提出用issue,scope,point还有why test的方法，你可以看一下，下载地址：http://www.laws4u.net/download/index.htm

  我不是牛人，但希望能帮到你。祝你好运。

尝试解释一下
第一题答案没有问题，原文里两个人的重点不一样，一个完全是根据人的生理特征来判断的，另一个是根据实际情况来判断的，如：那种咚咚走路时要左右退绕着走，呵呵，我是没有办法这样走的
而根据这两种情况得出的结论又是不一致的
c中所说的可能性问题好像和原文没有什么关系，两人的可能性都很大啊，可能性是什么咚咚啊

第二题就更好弄一些，举例，乙肝
因为这种病传染初期没法确认，所以光是把那些表现出病症的全杀光是没有用的，因为很多得病的还没有发出来，这样是根治不了的
你实在不理解就把那种病换成乙肝想想，呵呵，这个例子应该能解决问题的
