GWD17-Q11:
Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.  Clearly, dropping this restriction would allow the other species to recover.

Which of the following, if true, most seriously undermines the argument?

A.    Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
B.    It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
C.    The number of snow geese taken by hunters each year has grown every year for several years.
D.    As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
E.    In the snow goose’s winter habitats, the goose faces no significant natural predation.
没看出B哪里削弱了

Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs' airways to contract.  This partially seals off the lungs.  An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust.

Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above?

(A) Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks.
(B) Researchers do not yet know what makes one person's messenger molecules more easily activated than another's.
(C) Such a medication would not become available for several years, because of long lead times in both development and manufacture.
(D) Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air.
(E) Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started.

我发了帖子米有人回答~看见了大好人在这里~~谢过！！！
By competing with rodents for seeds, black ants help control rodent populations that pose a public health risk.
However, a very aggressive species of black ant, the Loma ant, which has recently invaded a certain region, has
a venomous sting that is often fatal to humans. Therefore, the planned introduction into that region of ant flies,
which prey on Loma ants, would benefit public health.

Which of the following, if true, most strengthens the arguments?

A. Ant flies do not attack black ants other than Loma ants.恩其实这道题我有印象，不过我觉得其实我第一次看到这个选项会先排除，然后我会等之后其余选项都看完之后再选，我当时记得这道题其他选项都是无关
E. The use of pesticides to control Loma ants could have harmful effects on the enviroment.这个原文是一直再说，现是有个普通蚂蚁，然后又说这个L有问题，所以引进一种
the planned introduction into that region of ant flies就会捕食L，所以有益，所以，很明显这个无关。




现在理解A对了，但是还是不能理解为什么E不对。
我的想法是，原来用的pesticides会有harmful effects，所以我现在引入planner introduction of ant files，就不用再用那些有harmful effects的pesticides。

请大家纠正我~谢谢。

请教楼主一下，这是曼哈顿模块里面的第一题，很杯具的我完全看不懂，看了解释还是有点晕，

A recent article stated that only 5.5% of American colleges grant the majority of their degrees in the liberal arts.
Citing this, a reader wrote to lament that this was further evidence of the decline of academic rigor in American
post high school education.

Which of the following is an assumption on the part of the reader?--答案C。 为什么呢？怎说呢，这个我看过M的讲解应该很清楚，我觉得你没有理解这篇文章的主要以四，就是说现在授予art学位的大学才5。5%，所以读者就认为未来the decline of academic rigor in American post high school education.

       A.The percentage of American colleges granting liberal arts degrees would continue to drop.感觉跟没说一样
       B.All colleges should grant the majority of their degrees in the liberal arts.  应该干什-与原文无关        
C.Most postsecondary scientific, engineering, and vocational training does not involve as
much academic rigor as liberal arts training. 这个就是说其他没有增加授予的可能，正好取非削弱
      D. Academic rigor is the most important aspect of post high school education.  
E.Of the colleges that do not grant the majority of their degrees in the liberal arts,
many granted fewer than a quarter of their degrees in the liberal arts.

原文整体在说迁移，而且这个地方是需要的是加强，加强按照m说的就是由加强的意向就可以，不用100%的。而且，话说回来，以前lawyer讲的都是先排除那些无关的。然后再考虑剩下的。还有事例的加强〉道理的

楼主我很贪心，再问一道题行不?(*^__^*) 嘻嘻……
GWD1-Q13:
In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years.  Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses.
Which of the following, if true, most seriously weakens the argument?

A.Florida attracts more people who move from one state to another when they retire than does any other state.是像没有什么关，但感觉比d 要接近一点。 对的，这个就是在说会吸引更多的人与其他地方相比，这个确实没用
B.The number of people who move out of Florida to accept employment in other states has increased over the past ten yea无关rs.
C.There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees无关
D.The total number of people who retired and moved to another state for their retirement has increased significantly over th
e past ten years.  难道说local  business 的生意在another  state也有做？恩，他在说基数大，你想一个盘子，盘子做得很大如果偶然出了一个问题也不会出事的利害，你可以想想那些银行，交行比较早盘子大，所以危机来的时候，整体的增长也是正的而且大于其他银行。
E.The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.

GWD17-Q11: 这道题相当interesting,首先顺一下逻辑链条，a地的鸟被g这种最近在增长的东西所替代，g虽然是捕猎的对象，但是很不幸打猎季节有规定，如果相对减少了5%就会提前停止。所以去掉这个约束，更多的当地生物会恢复。
Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese,
which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a
popular quarry for hunters in the southern regions where they winter, the hunting season ends if and

Which of the following, if true, most seriously undermines the argument?

A.    Hunting limits for snow geese were imposed many years ago
in response to a sharp decline in the population of snow geese.
B.    It has been many years since the restriction led to the hunting season
for snow geese being closed earlier than the scheduled date.我当时就是AB迷惑了，其实你重点必须抓住原文，原文说的restriction是啥很重要，就是那个提前结束的法令，所以A说的很明显对象部队，错误，B就是说去掉了也没用，你想这个市最近鸟类减少，问题是你这个约束n多年前就有了，要是真是约束的原因，我怎没见你早期就申报要停止！！所以B 记住：相关/无关提速！！
C.    The number of snow geese taken by hunters each year has grown every year for several years.
D.    As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
E.    In the snow goose’s winter habitats, the goose faces no significant natural predation.

关于这个题的E，否定一种别的可能性不是也算一种支持吗？那E里说用杀虫剂控制它不行，不就也是否定一种其他方法吗。。用来支持原文那个可行的。。
