GWD-30-Q40和GWD-17-Q11

Investment banks often have conflicting roles.  They sometimes act for a client company by raising capital from other investment institutions as advantageously as possible, but their analysts also sometimes send unfavorable reports on the financial health of companies for whom they are raising capital to other clients who wish to make investments.  Analyses of companies’ financial health need to be unbiased if an investment bank is to achieve long-term success.

If the statements above are true, which of the following practices, if adopted by an investment bank, would hinder its long-term success?

1. Evaluating and rewarding the bank’s analysts on the basis of recommendations made by managers who are solely engaged in raising capital for clients
2. Using reports by the investment bank’s analysts to determine how best to raise capital for a client
3. Sharing the task of raising capital for a client with other investment banks
4. Ensuring that conflicts between analysts and those who raise capital for clients are carefully mediated and resolved by impartial arbitrators
5. Monitoring the success or failure of analysts’ current predictions about how companies will perform financially, in order to determine the value of future predictions

答案：A 能给解释一下吗？

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

1. Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
2. It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.

3. The number of snow geese taken by hunters each year has grown every year for several years.
4. As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
5. In the snow goose’s winter habitats, the goose faces no significant natural predation.

答案：B 求解谢谢！！！

我也求解GWD30-Q40，为什么选A？牛牛们赐教！

GWD30-Q40

投资银行是个两面派，一面帮着公司从另外一个投资公司融资，一面他们的分析员又给投资公司提供该公司的财务报告，那么只有做到没有偏见的报告才能基业长青。

问下面哪个选项能使得投行变得基业长青

A：分析员的报告被仅负责融资的经理进行评估，这样两方面的意见能互相左右，减少偏见。

GWD-17-Q11

B 说，5%的指标很快就达到了，所以关闭狩猎的时间很早。说明总数已经减少，这样才能使得5%的指标很快达到

削弱题有时候能平感觉做啊．．．楼主要培养语感．．．．

GWD-17-Q11不明白前面的解释，我觉得B选项是加强不是削弱呢！

我选D，而且蛮肯定的。

题目：  说北极某鸟频危，原因是近年来雪鸭数量大幅增加，排挤了其他种群。说雪鸭在南方它过冬的地方是人民捕猎的对象，但有规定，雪鸭数量减少5%以后就不能捕猎了。 观点：应该取消禁捕的规定以使其他鸟类种群恢复。

分析：  观点的思路是，取消禁令--> 雪鸭数量下降更多更快--> 雪鸭就不排挤北极某鸟类了。  要削弱观点有两条路 1.说明即使取消禁令雪鸭数量也不会更多地下降；2.说明即使数量下降仍不能恢复北极某鸟类。

B： 说禁令这几年都很早就结束捕猎--> 说明每次捕猎数量都达到5%的禁令限量，即说明禁令有效控制了雪鸭减少的速度，也就是说没这个禁令捕猎数量能超过5%--> 那么取消禁令就确实能够使雪鸭数量更快更多地减少--> 那不是就支持了观点，取消禁令能保护北极某鸟了吗？！

A： 禁令是多年前因雪鸭数量大量减少而设立的 （与本题无关，就算雪鸭绝种了，我们要讨论的是能否保护其他鸟类；再说了原来鸭少了要禁，现在鸭太多了正好要撤销）

C： 说每年被捕猎的雪鸭数量都在上升：看看，和B一样的问题，假设每年都捕猎了5%，那么被猎掉的数量上升了，剩余的种群数量95%也在不断上升，总之证明被打掉的增加了不等于剩余雪鸭数量减少，同时，就算减少了，不能证明观点否：再多减少一点能更好的解决其他鸟类频危问题

D：正确。多好的理由啊，因为雪鸭数量大量增加，他们找了新的越冬点。 我们要的结论来了--> 即使取消禁令可能仍然不能使鸭子的数量减少到足够不排挤其它种群的地步，因为其他非捕猎区的雪鸭仍会不断茁壮繁殖种群数量

E： 与B一样，很好的加强选项之一。说是越冬地没有它的天敌-->那所以说只有人类的捕猎能够控制鸭群的数量，还不赶快撤销禁令么？

啊呀，累死我了，以后再不回这么长的帖子了

自我否定下哈，答案是B不是D，

关键是B这句话我理解错意思了。在美国人的理解当中 It has been many years  since XXXXX 的意思是XXXXX这件事已经许多年没有发生了。也就是说猎人很多年以来都没有成功打到5%的鸟了，这样B就是最好的加强了，因为取消前和取消后没有本质差异，猎人在减少雪雁上帮不了忙。而D的影响究竟如何相对不是那么确定的，是个很弱的削弱。具体可以看下面这个超长的帖子：

终于看明白了!谢谢楼主!逻辑确实要靠阅读啊....
