1. Scientific research that involves international collaboration hasproduced papers of greater influence, as measured by the number of times apaper is cited in subsequent papers, than has research without anycollaboration. Papers that result from international collaboration are cited anaverage of seven times, whereas papers with single authors are cited only threetimes on average. This difference shows that research projects conducted byinternational research teams are of greater importance than those conducted bysingle researchers.

Which one of the following is an assumption on which the argument depends?
K.W:
The number of citations a paper receives is a measure of the importanceof the research it reports

2. Prominent business executives often play active roles in UnitedStates presidential campaigns as fundraisers or backroom strategists, but fewactually seek to become president themselves. Throughout history the greatmajority of those who have sought to become president have been lawyers,military leaders, or full-time politicians. This is understandable, for thepersonality and skills that make for success in business do not make forsuccess in politics. Business is largely hierarchical, whereas politics iscoordinative. As a result, business executives tend to be uncomfortable withcompromises and power-sharing, which are inherent in politics.

Which one of the following, if true, most seriously weakens the proposedexplanation of why business executives do not run for president?
K.W:
Military leaders are generally no more comfortable with compromises andpower-sharing than are business executives.

3. Because of the recent transformation of the market, Quore, Inc.,must increase the next two years, or it will certainly go bankrupt. In fact,however, Quore’s production structure is such that if a 10 percent productivityincrease is possible, then a 20 percent increase is attainable.

If the statements above are true, which one of the following must on the basisof them also be true?

K.W: If a 20 percent productivity increase is unattainable for Quore,then it must go bankrupt.

4. Joseph: My encyclopedia says that the mathematician Pierre de Fermatdied in 1665 without leaving behind any written proof for a theorem that heclaimed nonetheless to have proved. Probably this alleged theorem simply cannotbe proved, since---as the article points out---no one else has been able toprove it. Therefore it is likely that Fermat was either lying or else mistakenwhen he made his claim.
Laura: Your encyclopedia is out of date. Recently someone has in fact provedFermat’s theorem. And since the theorem is provable, your claim---that Fermatwas lying or mistaken---clearly is wrong.

Joseph’s statement that “this alleged theorem simply cannot be proved” playswhich one of the following roles in his argument?
K.W: a subsidiary conclusion on which his argument’s main conclusionis based

The following appeared as part of the businessplan of the Capital Idea investment firm.
“Across town in the Park Hilldistrict, the Thespian Theater, Pizzazz Pizza, and the Niblick Golf Club haveall had business increases within the past two years. Capital Idea shouldtherefore invest in the Roxy Playhouse, the Slice-o’-Pizza, and the Divot GolfClub, three new businesses in the Irongate district. As a condition, we shouldrequire them to participate in a special program: Any customer who patronizestwo of the businesses will receive a substantial discount at the third. Bymotivating customers to patronize all three, we will thus contribute to theprofitability of each and maximize our return.”

AA:
1. We do not know by what source the three companies in Hill District increase their profits. Maybe they did not enlarge their sales by some discount, but focus on minimizing costs.
2. Our district may not be the same to the H district. The incentive program may not have any effect in our district.
3. It cannot be said that all 3 companies' profits will increase: Maybe patron for a the golf club is very expensive, people all tend to patron the other two to get discount for the Golf Club. Thus, golf club will inevitably lose money~~

第三题晕了。。 if a 10 percent productivity increase is possible 这是前提才会有20% attainable啊，但选项说它没有20%attainable就要倒闭了。那如果低于10%的productivity is possible呢？？那当然不会有20%attainable啊，那还要倒闭吗。。

这道题我觉得意思是说
Q必须要increase production---->才能避免倒闭
所以如果Q可以增加10% production----〉那么Q的attainable production会增加20%
于是答案是“ If a 20 percent productivity increase is unattainable for Quore,then it must go bankrupt. ”
依据答案的话，好像答案并没有把20%作为一个非常重要的因素，这里的20%是在描述production增加以后所带来的结果。所以只是用这个结果来推出非B---〉非A

找到的解释如下：
可简化题干的表述为：
transformation of the market（A）→Q increase its production（B）
Q not increase its production（非B）→Q will go bankrupt（C）

选项E的表述为：Q not increase production（非B）→Q will go bankrupt（C），与一致。

但是它是must be true题啊。那答案应该是完全没有漏洞的。如果它忽略了10%和20%，那就是有漏洞了。

作者: fox0923 时间: 2011-8-18 11:44
这个我也存在疑问，感觉的确是答案有漏洞，所以只好先按着答案的解释那么推一下，静待更好的解释~~~

作者: innerwarrior 时间: 2011-9-9 11:41
我的理解是原文说if 达到10%，那么20%是attainable的，那就是10% possible等价于20% attainable。
选项说：“ If a 20 percent productivity increase is unattainable for Quore,then it must go bankrupt. ”
20% not attainable，那也就是说10%也not possible，那一定bankrupt。

拙见～

作者: clover928 时间: 2011-11-8 20:19
我大概想到第三题答案为什么是productivity增加20%。由于题目要求连续两年profit都要上升才不破产，所以每一年的productivity都要上升10%。假设今年的productivity是a两年后的就是（1+0.1）^2a即1.21a，所以上升的是20%

1.前几次出现过
2.商人之间是阶级关系，政治史合作关系，所以商人不适应政治中的让位权力的方式，所以美国的商人没有参加竞选
weaken：商人参加竞选没有说服力拉不到选票所以才没有参加竞选

3.因为最近的Q超时的转变，他们应该提高产量否则就会倒闭，事实上这个超时的生产结构是：如果百分之十的增产是可能的，那么百分之二十也是可以达到的。。。

1.略。见1-9
2.44s
P:当总统的人里面少有商人。因为商业技巧和政治技巧不相同。商业是等级制，而政治是合作制。
C:商人们不喜欢妥协和权力分享，而这些在政治重视inherent
Weaken：如果能实现利润目标，商人们还是愿意从政的（找他因）；或竞选总统的商人很多，只是很少能成功（资料有问题）；或商人是因为难以步入政坛才不喜欢政治技巧（因果倒置）
3.30sP1：因为改革，Q公司要么增长要么破产
P2：事实上，对Q而言，如果10% 的增长是能实现的，那么20%的增长就是可以保持的
MBT：只要增长，Q就应该不会破产？

P:至今没有人能证明这个t
C

F要么说谎，要么犯错了
L
P:最近有人证明了这个t
C:J的说法是错的——PF没有说谎或者犯错，很有可能证明了这个t

第一题昨天一样的喔

2. 超时了。。
BG1:企业家在美国总统选举过程中发挥了积极重要的作用，作为募资人等等。
BG2:但是他们自己通常不会成为总统，通常是律师、全职政治家等（漏了军官）
Explanation: 企业是权力阶层分明的，与政治不同。成功企业家的个性通常使他们不会在政治中也成功。他们不习惯妥协与分权。

Weaken: 另一个hierarchy分明的职业，如军官，同样能在政治中出色。

3. 45s
由于近期市场变革，Q公司若不增加（啥？），今年则将有可能破产。Q公司的生产模式是若能增加10%的生产，那么20%的增加也是可完成的。

Must be true: ..看了答案也没明白 TT

4. 超时了
J说：我的百科全书上说数学家P他称他提出过一个定理，虽然没有文字记载，但是任然是正确的。但是这个定理没有人能证明，所以他要么是在撒谎，要么这个定理就是错的。
L说你的百科全书是错的。其实最近有人证明了那个定理。所以你说P撒谎或者错误定理的论断是不正确的。

5. 又超时了。。
投资公司的计划：
BG：由于最近两年在P区，剧院、披萨店及高尔夫俱乐部这三家公司利润增加
Plan: 于是咱们今年也在I区也投资三家同行业的公司。但是有一个特别的项目：就是惠顾其中两家的顾客可以享受第三家店的折扣，以此带动整个三家店的营业额，增加我们的利润。

Flaw: 1. P区和I区情况不能类比。三家行业的供求关系未必相同。
2.special program未必会带来三家公司的同时盈利。

Conclusion: International collaboration paper are more important
Assumption: Importance= Being cited frequently

2. 30‘
Premise:  Lawyers, military leaders, or full-time politicians seek to become politicians
Business is largely hierarchical, whereas politics is coordinative
Conclusion: Business executives tend to be uncomfortable with compromises and power-sharing, which are inherent in politics.
Weaken: 律师什么的compromises and power-sharing也不舒服

1. 做过，因果，gap

2. 44’
C: business executives do not run for president
P: politics are coordinative, while business is dominate
P: business executives are not comfortable with sharing power with others
【因果】因为商业是有等级的，政治需要合作，商业和政治不同的性格和技能决定他们各自的成败。所以商人一般不会成为政治领袖，因为商人不习惯和别人合作分享权力。
削弱原因，就是削弱因为性格不同而导致商人不适合政治家的原因。指出性格不是真正原因，指出他因。
Other reasons while not the personality make businessman not run for presidency

3. 43’
P: if 10 percent of productivity increase is possible, then 20 percent is attainable
P: because of recent transformation of the market, Q must increase the next two years. Or it will go bankrupt
归纳。Transformation---increase the next 2 years---10 percent productivity---20 percent---or bankrupt
a 20 percent productivity increase is unattainable for Quore, then it must go bankrupt.

原文逻辑链20 percent----or bankrupt, 答案not 20 percent---bankrupt
原文的意思是说next two years must increase, otherwise bankrupt. 所以如果20 percent is unattainable, 就是not must increase, 当然就会bankrupt

4. 51’

Joseph: My encyclopedia says that the mathematician Pierre de Fermat died in 1665 without leaving behind any written proof for a theorem that he claimed nonetheless（放在he claim前面更好理解）to have proved.

Joseph’s statement that “this alleged theorem simply cannot be proved” plays which one of the following roles in his argument?
这个题被nevertheless给坑了，所以完全没看懂QAQ
J：尽管P说T被证明出来了，但是在他死之前没有任何书面证据
C：所以这个T根本不能被证明
而且像他书里说的——没有别的人能够证明出来——所以P要么是在说谎，要么是搞错了
L：你的百科全书out of date 了，最近有人证明出来了。
因为T是可证明的，所以你说“他搞错了或者是说谎”是错误的
