1、1. Mr. West: Well, Ms. Smith, by how much do you plan to increase your donation to the cultural society this year? You know how many worth while projects we do.            

Ms. Smith: I’m not so sure of that. I was very upset about the statue you purchased last month. I think I’ll give no more money to your cause.

Mr. West: That’s all right: we’ll just put you down for the same amount that you gave last year.
Which one of the following words or phrases has been misinterpreted in the conversation?

(A) “increase”

(B) “you know”

(C) “worthwhile”

(D) “no more”

(E) “same amount”
--------------------------------------
答案是D。
关键在于Mr. West 对 Ms. Smith话中I think I’ll give no more money to your cause的理解出现了问题。Ms. Smith的意思是由于购买的问题不再给钱了，即：no money的意思。而Mr. West 将no more money 理解成no more money than that of last year。
因此，选D

请教版主一道狒狒宝典题目，非常疑问！
21. Historian: We can learn about the medical history of individuals through chemical analysis of their hair. It is likely, for example, that Isaac Newton’s psychological problems were due to mercury poisoning; traces of mercury were found in his hair. Analysis is now being done on a lock of Beethoven’s hair. Although no convincing argument has shown that Beethoven ever had a venereal disease, some people hypothesize that venereal disease caused his deafness. Since mercury was commonly ingested in Beethoven’s time to treat venereal disease, if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct.
Which one of the following is an assumption on which the historian’s argument depends?
(A) None of the mercury introduced into the body can be eliminated.
(B) Some people in Beethoven’s time did not ingest mercury.
(C) Mercury is an effective treatment for venereal disease.
(D) Mercury poisoning can cause deafness in people with venereal disease.
(E) Beethoven suffered from psychological problems of the same severity as Newton’s.
我的答案是D，可是宝典上说是B？ B是正确答案吗？
B只能理解为：贝多芬同学用M治venereal(性病），除此以外的人都不用M治病。
可是HYPOTHESIS中的DEAF又作何解？

决战金秋：这是我的lsat section 1 的专帖啊。以后不能再来专帖发贴了啊。在这个版面中发新帖。
我认为答案应该是狒狒说的B。
测定水银的目的是确定他有没有患性病。但若水银是大家普遍服用的一样东西，则测出来也不能说他患了性病。因此，在B的时代，至少有一部分人，是不服用水银的，这时才能确定。

2、Handwriting analysis—also known as graphology—is a poor way to predict personality types, even though it is used by 3,000 United States firms and by a majority of European companies. In a recent study, five graphologists scored no better than chance in predicting the occupations of forty professionals.

Which one of the following is an assumption necessary to the argument?

(A) People in the same occupation usually do not have the same personality type.

(B) Graphology is an effective means of predicting personality types in non-business contexts.

(C) There are more United States firms that do not use graphology than all the United States and European firms that do use it.

(D) There are several other techniques for predicting personality types that are more accurate than graphology.

(E) There is a correspondence between type of personality and choice of occupation.
---------------------------------
选项A：无关选项。因为不管相不相同，若有效，就能准确地预测出来。
选项B：题干中没有讲到非商业系统的问题。更没有比较问题。
选项C：这种比较也是题干中没有提供的信息。无关选项。
选项D：题目没说其他的方法。因此，也是无关选项。
选项E：由于作者的推论是用“预测职业”来做论据，推出它is a poor way to predict personality types，因此，作者的假设必定是基于两者之间有必然的联系。
正确答案是E。

Questions 3-4
The simple facts are these: the number of people killed each year by grizzly bears is about the same as the number of people killed by lightning on golf courses. And the number of people killed by lightning on golf course each year is about the same as the number of people electrocuted by electric blenders. All the horrible myths and gruesome stories aside, therefore, a grizzly bear is in fact about as dangerous as an electric blender or a game of golf.

3. Which one of the following is an assumption that the author relies upon in the passage?

(A) Most incidents involving grizzly bears are fatal.

(B) Grizzly bears are no longer the danger they once were.

(C) The number of fatalities per year is an adequate indication of something’s dangerousness.

(D) A golf course is a particularly dangerous place to be in a thunderstorm.

(E) Something is dangerous only if it results in death in the majority of cases.
--------------------------------------
条件：在bears，golf course和electric blenders上的每年死亡人数相等，
结论：他们同样危险
假设：死亡人数可以充分表明一个东西的危险度。（架桥）

4. Which one of the following, if true, would most effectively undermine the author’s argument?

(A) Although the number of people killed by lightning on golf courses each year is very small, the total number of lightning fatalities is many times greater.

(B) Electric blenders are among the safest household appliances; were the author to compare fatalities from electrical appliances in general, she would get a much higher figure.

(C) Most people would rather take their chances with blenders and golf games than with grizzly bears.

(D) Bears in general—including black, brown, and cinnamon bears, as well as grizzly bears—kill many more people than do electric blenders.

(E) Statistics show that the number of times people use electric blenders each year exceeds the number of times people play golf each year, which in turn far exceeds the number of contacts people have with grizzly bears each year.
-------------------------------------------------
削弱题
E为正确答案，表明死亡数字相等不能反映危险度，比如接触1000次，死一次和接触1次死一次，虽然都是一次，危险性大不相同。
这题告诉我们：比较不能只比较绝对数字，要比较相对数字。
C位迷惑选项，它只说了意愿，但没说明实际情况如何。

谢谢可爱的TONGXUN，就是看到你的图片我才加入了这个新家。
最近眼花，没看清你写的标题，不好意思。
那道题我明白了，主要是没看清 Since mercury was commonly ingested in
Beethoven’s time （我看成了我敬爱的Beethoven患了性病）
非常感谢你的分析。我在其他地方再讨教

5. Emperor: The enemy empire across the sea has harassed us for centuries. I want to conquer it and stop it once and for all. What advice can you give me?

Admiral: If you cross the sea, a mighty empire will fall.

Emperor: In that case, prepare the troops. We set sail tonight.

Of the following, the strongest criticism of the Emperor’s decision to invade would be that it

(A) Is certain to lead to the emperor’s defeat
(B) Is based on opinion rather than objective facts about troop strength
(C) Contradicts the Admiral’s statement
(D) Fails to consider fully the possible meanings of the Admiral’s advice
(E) Is a futile strategy for solving the problem at hand
--------------------------------
削弱题
题目不难，我觉得关键是读题后自己先思考一下
答案D：emperor没能完全理解admiral "a mighty empire"的可能含义（the enemy empire across the sea 或 their own country）
