12. 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.
答案是A,
我想A是否是他因削弱,C,D不是更好吗?C,D否定了前提:many smokers are snoring.?

The press reports on political campaigns these days as if they were chess games. One candidate's campaign advisor makes a move; the other candidate's advisor makes a countermove. The press then reports on the campaign advisors and not on the candidates. The losers in the chess game are the voters. They are deprived of the information they need to make informed decisions because the press is ignoring substantive policy issues and reporting only on the process of the campaign. It is clear that the campaign advisors should stay out of the limelight and let the press report on the most revealing positions on substantive issues the candidates have taken.

13. Which one of the following is an assumption upon which the argument in the passage depends?

(A) Chess is the most appropriate analogy to reporting on political campaign.

(B) The candidates in the election are taking positions on substantive policy issues.

(C) How the press reports politics determines the substantive issues in the
campaign.
(D)The voters are not paying enough attention to the election to be able to make informed decisions.

(E) There is no difference between reporting on the political process and reporting on substantive issues.
答案是B,
我选了C

19,Can any research be found to validate the contention that those who spend time plucking out their gray hairs have more negative attitudes toward the elderly than those who shrug their shoulders about their gray hairs? Unless a person's psychopathology leads him or her to overgeneralize, there is no necessary connection. Certainly it is reasonable to like the elderly yet dislike the idea of impaired eyesight and hearing. Furthermore, holding negative attitudes toward older people merely because they are old is immoral, according to nearly universally accepted ethical standards. But there is nothing immoral about disliking some concomitants of the aging process.

19. which one of the following best expresses the main point of the passage.

(A) It cannot be assumed that people who dislike some of the physical concomitants of growing old necessarily have negative feelings toward the elderly.

(B) To dislike some of the physical concomitants of growing old is reasonable, while to dislike the elderly is immoral.

(C) Since no one likes the physical concomitants of growing old, it is wrong to dislike the elderly merely because of their physical characteristics

(D) Being elderly is fine, but the process of becoming elderly is not, and people need to understand this distinction between the two.

(E) To dislike the elderly is immoral, and to do so just because on dislikes some of the physical concomitants of growing old is unreasonable.

答案:A,我选B

21,
21. A society in which there are many crimes, such as thefts and murders, should not be called "lawless" That is an abuse of the meaning of words. As a suffix "less "means "without" so "lawless" means "without laws." However, a society that has no laws has no crimes, because no laws can be broken. A lawless society would, therefore, be a crimeless society. So what some have termed a lawless society should actually be called "crimeful".

If the statements in the passage are true, which one of the following must also be true?

(A) A society that has laws has crimes.

(B) A society that has no crimes has no laws.

(C) A society that has many laws has many crimes.

(D) A society that has some crimes has some laws.

(E) A society that has many crimes has many laws.

答案
虽然我猜对了,但是D,E不是皆可,我做这种题,只猜有some的选项.

谢谢!

12. 经过排除我想选A,D。因为作者假设吸烟导致打呼噜，而不是打呼噜导致吸烟，所以C可以排除。排除D，我想most smoker跟提干里面的though not common in both group 有联系，从语气上是不必要的，所以不如A.

13. 这题我看完题干（没看选项），我猜答案应该是假设advisor不能做到的candidate能做到。B基本上就是这个意思了。C答案是迷惑选项，我想排除的理由是：提干的结论是：It is clear that the campaign advisors should stay out of the limelight and let the press report on the most revealing positions on substantive issues the candidates have taken. 所以作为假设的必要条件最好与该结论有关。比如我觉得如果答案是 the press can distinguish the difference between substantive issue and process of the campaign 也比C好，C有点象评价题答案噎。

19. A,B答案看上去都好,不过B选项像是下结论,而且语气坚定,提干里作者没有,所以A更好.

21. 我想GMAT里不会有这种题. some many的区别我想是:some指只要有犯罪就有法律. many指很多了.

12, 同意选A,D
如果A:Stress induces snoring in certain individuals. 答案一定是A,但是A中又提到了
snoring.会不会影响其削弱?做这种削弱题时,是不是不用管snoring, 只要有提到他因就选.
排除D，我想most smoker跟提干里面的though not common in both group 有联系，从语气上是不必要的，能否讲讲你的意思,我不太理解.

13, assumption是否属于bridge 型的?
坚决同意:作为假设的必要条件最好与该结论有关。

19,B选项是原文明确提到的.
Certainly it is reasonable to like the elderly yet dislike the idea of impaired eyesight and hearing =>To dislike some of the physical concomitants of growing old is reasonable,
holding negative attitudes toward older people merely because they are old is immoral =>while to dislike the elderly is immoral.
所以我觉得B比A更好.

21,
some指只要有犯罪就有法律. many指很多了.
如果这样理解的话,那么LSAT中很多some ,many ,all 的题目就可以理解了

非常感谢!

12. 我的意思是,most smokers do not snore,如果削弱的话就是大部分吸烟者都不打呼噜,提干里提到though not common in either group虽然在两组人里都不普遍,所以说大部分吸烟者都不打呼噜就不能很好的削弱那些不普遍的人了.

19. 这题属于归纳(要求满足必要性)里面的中心思想题, 而不是简单的infer题(他们的差别我觉得是infer题只要是从文中得出的必要条件或肯定能推出的答案就可以,可以从文中一部分,也可以根据全文; 问main idea的中心思想题要概括整个提干作者主要表达的意思或意图):
A.是一个推导出的结论(而且说法很圆滑).
可是B, 前半句Certainly it is reasonable to like the elderly yet dislike the idea of impaired eyesight and hearing =>To dislike some of the physical concomitants of growing old is reasonable 需要假设the idea of impaired eyesight and hearing=physical concomitants of growing old; 后半句holding negative attitudes toward older people merely because they are old is immoral =>while to dislike the elderly is immoral. 如果没有merely because they are old还可以, becasue the are old 的意思强调了年龄歧视. 比如 an elderly thief 是不是就可以说他immoral了?
上面这些倒是其次, 就像你写的=>,读一读题目,作者先设问,花时间拔白头发的人比起对白发不屑一顾的人更敌视老年人的争论能被任何调查得出吗? (A:不能假设不喜欢岁月痕迹的人肯定敌视老年人) 后面围绕这个问题作出讨论,得出结论Certainly it is reasonable to like the elderly yet dislike the idea of impaired eyesight and hearing. Furthermore, holding negative attitudes toward older people merely because they are old is immoral, according to nearly universally accepted ethical standards. But there is nothing immoral about disliking some concomitants of the aging process. 你说这篇文章想表达的主要观点是什么? 你在仔细理解一下那个设问句. 这题就像中学语文题, 有意思. 而且GMAT答案不是说不选的就肯定都有逻辑错误, 我们要找最好的.

12 我理解你的意思了
请问A:Stress induces snoring in certain individuals. 答案一定是A,但是A中又提到了
snoring.会不会影响其削弱？这样削弱有没有影响？

19，你解答得太好了！！
我真是没有仔细分清infer, main idea and conclusion 这些归纳题之间的差别，现在越看答案越是A。

非常非常感谢过年兄弟！！
