A recent study found that snoring, though not common in either group, is more common among smokers than among nonsmokers. On the basis of this evidence, the author hypothesized that smoking by itself can induce snoring. Which one of the following, if true casts the most doubt on the author's hypothesis?
(A) Stress induces both snoring and smoking in certain individuals.
(B) Obesity induces many individuals to smoke
(C) Most snorers do not smoke
(D) Most smokers do not snore.
(E) Both smoking and snoring cause throat problems.
Answer: A why not D?
正如siebel所讲,这是一个关于相对值的题目,和绝对值无关.A是典型答案,其它答案还有:不是snoring导致smoking.
吸烟问题是一个典型的逻辑陷阱：AB同时伴生，A 一定是B的原因吗？最有力的驳斥是C 导致A B
大多数的吸烟人不打呼噜不能说明吸烟不会造成人打呼噜。一个是效果，一个是原因。好比大多数吸烟人没有得肺病不能证明吸烟不会导致肺病。
  14-9-9. Some people are Montagues and some people are Capulets. No Montague can be crossed in love All Capulets can be crossed in love .Therefore, Capulets are not Montague Anyone who is not a Montague is intemperate. Assume that all of the statements in the passage are true, If it is also true that no Montague is intemperate, then which one of the following must be true?

(C) All intemperate people can be crossed in love.
(D) All intemperate people are Capulets
(E) All Capulets are intemperate.
这种题目我看到就晕，能否再讲讲.答案是e 。
原题的信息: 1. ALL Montague are not crossed in love 2. ALL Capulets are crossed in love3. Anyone who is not a Montague is intermerate 4. Montague 和Capulets集合不重叠
A提到了crossed in love的信息,而且是crossed in love 的必要条件..原文1,2信息根本无提到.错.
(B) 表示二选一..原文没提到.
(C) All intemperate people = NOT Montague    can be crossed in love.  原文没提到,可能还有第三类人.
(D) All intemperate people = NOT Montague    are Capulets  错
(E) All Capulets are intemperate. 由 3,4可得
可以看到BCD的错误其实是一样的...都是ASSUME除了Montague和 Capulets外没有第三类人

Between 1951 and 1963, it was illegal in the country of Geronia to manufacture, sell, or transport any alcoholic beverages. Despite this prohibition, however, the death rate form diseases during the first five years of the period than it was during the five years prior to 1951. Therefore, the attempt to prevent alcohol use merely make people want and use alcohol more than they would have it had not been forbidden. Each of the following, if true, weakens the argument EXCEPT:
(A) Death form an alcohol-related disease generally does not occur until five to ten years after the onset of excessive alcohol consumption.
(B) The diseases that can be caused by excessive alcohol consumption can also be caused by other kinds of behavior that increased between 1951 and 1963.
(C) The death rate resulting from alcohol-related diseases increase just as sharply during the ten years before and the ten years after the prohibition of alcohol as it did during the years of prohibition.
(D) Many who died of alcohol-related diseases between 1951 and 1963 consumed illegally imported alcoholic beverages produced by the same methods as those used within Geronia.
(E) Between 1951 and 1963, among the people with preexisting alcohol-related diseases, the percentage who obtained lifesaving medical attention declined because of a social stigma attached to excessive alcohol consumption.
答案:D
原文：因为戒酒法律执行期间，因为VIRUS而引起的DEATH上升。
所以戒酒法律引起更多人喝酒
现象解释Weaken的方式：
A之前引起的，有潜伏期(别的解释)
B 可能别的原因引起的（他因）
C 法律执行前后和期间死亡增长一样猛（通过比较，切断法律和死亡增长的关系）
E之前有病的人，期间因为医治的少了导致死亡（他因）
D无法削弱
