to redhat,

the conclusion: blackbirds benefit by their nesting experience

B supply another cause: their capacity of lay viable eggs increase with each successive trial

就是说黑鸟的繁殖成功率的提高不是得宜于筑巢经历，而是由于它们下成活率高的蛋的能力随每次successive trial提高了,

但我不太理解这里trial作什么解释

to bessette:

Good luck to you.

大概了解了, 是不是说
就是说黑鸟的繁殖成功率的提高不是得宜于筑巢经历，而是由于它们下成活率高的蛋的能力随每次successive trial提高了, so 不是benefit their nesting experience
而这trial是不是equal to “nesting” 但还是不了解有何weaken之处?

是“他因削弱”

这里“下成活率高的蛋”就是“他因”

Many people change their wills on their own every few years, in response to significant changes in their personal or financial circumstances. This practice can create a problem foe the executor when these people are careless and do not date their wills: the executor will then often know neither which one of several undated wills is the most recent, nor whether the will drawn up last has ever been found. Therefore, people should not only date their wills but also state in any new will which will it supersedes, for then there would not be a problem to begin with.

The reasoning in the argument is flawed because the argument

(A) treats a partial solution to the stated problem as though it were a complete solution.

(B) Fails to distinguish between prevention of a problem and successful containment of the adverse effects that the problem might cause.

(C) Proposes a solution to the stated problem that does not actually solve the problem but merely makes someone else responsible for solving the problem.

(D) Claims that a certain action would be a change for the better without explicitly considering what negative consequences the action might have.

(E) Proposes that a certain action be based on information that would be unavailable at the time proposed for that action.

答案A,我这题不理解，帮我看看。

1
A physician who is too through in conducting a medical checkup is likely to subject the patient to the discomfort and expense of unnecessary tests. One who is not thorough enough is likely to miss some serious problem and therefore give the patient a false sense of security. It is difficult for physicians to judge exactly how thorough they should be. Therefore, it is generally unwise for patients to have medical checkups when they do not feel ill.

1. Which one of the following, if true, would most seriously weaken the argument in the passage?

(A) Some serious diseases in their early stages have symptoms that physicians can readily detect.

(B) Under the pressure of reduced reimbursements, physicians have been reducing the average amount of time they spend on each medical checkup.

(C) Patients not medically trained are unable to judge foe themselves what degree of thoroughness is appropriate for physicians in conducting medical checkups.

(D) Many people are financially unable to afford regular medical checkups.

(E) Some physicians sometimes exercise exactly the right degree of thoroughness in performing a medical checkup.

我看不出A是怎么削弱的，难道题目假设Some serious diseases in their early stages是感觉不出来吗？

谢谢！

检察官有两个难点，办法只解决了第一个
关于最后的will是否能找到这个问题没解决。

1。这个题的削弱方向应该是这样一个意思：
   虽然医生很难确切的把握精确度，但有些严重病通过早期确诊还是能搞定的
   这就削弱了结论的一概而论。

to zyh79,

19题我理解了；

但1题我是这样理解的：医生检查太全面会给病人带来不舒服和不必要的费用，但是不全面的话又会遗漏一些重病，医生很难把握这个度。所以说病人在感觉好的时候去检查是不明智的。

选项A说：有些病的初期症状还是检查的出来的，也就是说去检查还是有用的，不能因为可能带来的不必要的费用和不爽而忽略了检查的最有价值的方面。

但我觉得这里得有这样一个假设：严重疾病的初期症状人们是感觉不到的。

zyh79

嗯。可以说你这个假设有那么一点味道
    不过，我觉得病人感觉到与医生检测到还是有差距的，
    除非你的假设上还隐含这样一个命题：初期病人的感觉一般也都是准的。

25. All of the best comedians have had unhappy childhoods. Yet, many people who have had happy childhoods are good comedians, and some good comedians who have had miserably unhappy childhoods are happy adults.

If the statements in the passage are true, which one of the following CANNOT be true?（A）

(A) The proportion of good comedians who had unhappy childhoods is greater than the proportion of the best comedians who did.
(B) Some good comedians have had unhappy childhoods and are unhappy adults.
(C) Most of the best comedians are happy adults.
(D) More good comedians have had unhappy childhoods than have had happy childhoods.
(E) The proportion of comedians who are happy adults is higher than the proportion who are unhappy adults
我认为很简单,因为答案a与题干基本无关,且推倒不出它

to zyh79,

回归GMAT做PP3逻辑汇总就可以了吗？PP3逻辑汇总就是那121道题，而且选项没有ABCDE的？

以下是引用bessette在2002-10-27 17:05:55的发言：
principle: good => benefit + good intention
           bad intention OR likely cause harm => bad

A: intention( attempt to cause trouble) => bad
   benefit + bad intention => not good (bad) 这是应用第一个原则的等价原则(逆否命题) 

(A) Pamela wrote a letter attempting to cause trouble between Edward and his friends; this action of Pamela’s was morally bad, even though the letter, in fact, had an effect directly opposite from the one intended

我也选A
A不是符合bad intention OR likely cause harm => bad吗?

"even though the letter, in fact, had an effect directly opposite from the one intended"是什么意思啊

请高手帮忙THANKS!
