Which of the following best completes the passage below?
People buy prestige when they buy a premium product. They want to be associated with something special. Mass-marketing techniques and price reduction strategies should not be used because________.
前提：People buy prestige when they buy a premium product want to be associated with something special.（目标）
结论：Mass-marketing techniques and price reduction strategies should not be used（方案）
A. Affluent purchasers currently represent a shrinking portion of the population of all purchasers 富裕的 购买者 占据了 缩水的一部分（富裕的购买者数量减少---无关项）
B. continued sales depend directly on the maintenance of an aura of exclusivity
持续的销售之间建立在维持领域的排外性与排他性（mass-marketing technique 不采用）方案可行性加强？
C．purchasers of premium products are concerned with the quality as well as with the price of the products
消费premium products 的顾客关心质量和价格（目标 不成立 无关 方案）
D.        expansion of the market niche to include a broader spectrum of consumers will increase profits
延伸市场----包括更广阔的范围（顾客） 的提升利润
E. manufacturing a premium brand is not necessarily more costly than manufacturing a standard brand of the same product 生产加价产品不是必要 cost 更多（与生产standard 产品相比）

对于上题的分析 我按照 方案推理的模式来 但在目标方面 不是很清晰（求大神指正）

Prep2012-Pack1-CR-002 VCR07580 Easy ？ 演绎推理
Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.
Sharon: But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, 1 or more will very be unemployed.
R；90%的人知道有人unemployed
S：正常比例是5%，所以 大约50个人 1或大于1 的人是unemployed
Sharon's argument is structured to lead to which of the following as a conclusion?
A. The fact that 90% of the people know someone who is unemployed is not an indication that unemployment is abnormally high.
B. The current level of unemployment is not moderate. （A给出的 是不确定 失业与就业比 只是知情权 无法与S所给出的数据进行比较）
C. If at least 5% of workers are unemployed, the result of questioning a representative group of people cannot be the percentage Roland cites.
D. It is unlikely that the people whose statements Roland cites are giving accurate reports.
E. If an unemployment figure is given as a certain percent, the actual percentage of those without jobs is even higher.

对于上题，是否为演绎推理 不太确定

An influential stock analyst recommends the purchase of three infrequently traded stocks in each of his weekly magazine columns. Unusually large amounts of these stocks are often purchased one day before the magazine appears on the newsstands. This pattern has recurred over a period.
Suppose that the information presented above is accurate. Each of the following statements, if true, could help to explain why the unusually large purchases occurred EXCEPT:
A. Workers at the company that prints the magazine have used their advance knowledge of the analyst's column to guide their own stock purchases.
B. Workers at the company that prints the magazine often sell advance copies of the magazine to stockbrokers.
C. One hundred copies of each issue of the magazine are circulated in the publishing company's office a day before the issue appears on newsstands.
D. The analyst refuses to submit his column for editorial review before it is printed.
E. Twenty people in the publishing company have access to the analyst's column before it is printed.

Prep2012-Pack1-CR-018 VCR014017 Easy 因果？？？？、B/E
Airport official: Local residents have been complaining that night fights into Plainsville airport disturb their sleep and should be sharply reduced in number. This complaint is completely unreasonable—there have been night flights coming into the airport from the very beginning, twenty years ago, and these residents should have taken that fact into account when buying their homes.
因果联系（因特）；干扰因素
前提： there have been night flights coming into the airport from the very beginning, twenty years ago, and these residents should have taken that fact into account when buying their homes.
结论：This complaint is completely unreasonable
Which of the following is an assumption on which the airport argument depends?
A. There are fewer night flights now than there were originally. （无关因果）
B. The residents who are complaining have been in their current homes fewer than twenty years.
C. The residents who are complaining are ignoring the benefits they gain from the presence of the airport.
D. The economic success of the airport depends entirely on the existence of the night flights.
E. People buying houses in Plainville all avoid buying houses near the airport if they can.
此题：对于BE 之间的抉择，正确答案为B， 但是在我看来E 更能解释unreasonable.(如果是B 的话，个人观点：还需要表示一个变化的过程)---且求大神指点


Prep2012-Pack1-CR-028 VCR000739 Medium           果因？
Mall owner: Our mall's occupancy rate is so low that we are barely making a profit. We cannot raise rents because of an unacceptably high risk of losing established tenants. On the other hand, a mall that is fully occupied costs about as much to run as one in which a rental space here and a rental space there stands empty. Clearly, therefore, to increase profits we must sign up new tenants.
Which of the following, if true, most seriously weakens the argument?
前提：无法提升 租金；  空mall 和满mall的cost是一样的。
Our mall's occupancy rate is so low that we are barely making a profit.（现象）
结论：to increase profits （目标）we must sign up new tenants. (方案) -------原因1
A. The mall's operating costs could be cut by consolidating currently rented spaces in such a way that an entire wing of the mall could be closed up.      因果联系 有其他方案？（有它因）
B. The mall is located in a geographic area in which costs incurred for air-conditioning in the hot summers exceed those incurred for heating in the mid winters by a wide margin. (无关天气)
C. The mall's occupancy rate, though relatively low, has been relatively stable for several years.
D. The mall lost tenants as a result of each of the two major rent increases that have occurred there.
E. None of the mall's established tenants is likely to need additional floor space there in the foreseeable future.

该题无法确定是否分类为果因。 因为有 方案穿插，但是个人觉得又不是完全的 方案推理。求大神搭救

上来滚一滚 。。。。

flhuihui1001

不明白你想问的问题是什么。你是想问这种题在herl中的归类么还是想问这道题怎么解？ herl 归类这个问题我没有太在意，所以没办法回答分类问题。但可以帮忙解释一下你发的题。
术语即使： P = Premise    C= conclusion

题目1：

P1: buy premium products -- prestige and feel special
P2: 待选
C: cannot decrease price or use mass marketing techniques

此题谈到premium products和 marketing technique的因果关系。因为购买者需要prestige 和something special --->不能使用大众营销方式。那么prestige、 something special 又和mass marketing、price decrease有咩关系呢？这就需要P2来fill the gap。
AC 你已经判断了无关，因此主要说BDE

B 持续销售需要维持 独一无二的光环 -----CORRECT   mass marketing ---> more people buy premium products ---> they’re not special.  While continued sales need the aura of exclusivity.  Mass marketing will damage the aura of exclusivity ---> ( if you want to continue to sell them) do not use this mass marketing
C 高档产品购买者及关心质量也关心产品价格    购买者关心啥和这个因果关系无关
E 更多顾客，扩展专门市场会提高利润。   和此因果关系无关

这题的核心是判断因果关系，你可以参考相关因果，或者国因推断那部分。

题目2
P1 90% people know someone unemployed
P2 a normal moderate level :  5% unemployment – means 20 个人里面1个人失业（简单的数学概率）
P3 认识50个人， 至少1个人失业 （符合P2的概率描述）

这道题算推理吧，不知道是不是叫演绎推理， 官方吧这类题叫做must be true 类型，就是用所有已知信息 P1 P2 P3 来推断一个必然成立的结论！
比如：P1： 我家人都爱吃苹果。 P2： JIM 是我的家人。P3：mary 住我楼上。从这三个信息你可以推出什么？ C1： JIM必然喜欢吃苹果。 但你不能推出mary 爱不爱吃苹果，因为题目中没说你和mary是不是家人。

回到prep的题。分析5个选项：
A： P1的内容不能说明失业率是否异常的高。  --COREECT。  失业率是指100个人里面有几个人失业。 与你认识几个失业的人有咩关系？ P1 不能反映失业率， 就像marry和你是朋友， 但不能推断她是否爱吃苹果一样。
B： 无法退出
C： 5%失业率 ， 和到底多少percent的人认识失业者，之间没必然联系。所以也不能判断R的引用数据是否可能
D  无关， 跑远了。没有信息可以推断R的引证的准确性
E  最后一条定律哪来的？ 完全没根据

其实这两个数据虽然都是失业，但是完全没办法对对方进行任何推理。 所谓这种数字上的推理游戏，GMAT能涉及到的至多是成本利润简单加减，速度时间的乘积这种 有坚实数学定理作为依靠 的推理。题目中P1P2两个没有互相的定量关系，所以A最合适： P1 不能证明失业率不正常。

题目3
An influential stock analyst recommends the purchase of three infrequently traded stocks in each of his weekly magazine columns. 意思: 有个很有名的股票分析师在他的周刊专栏上推荐了3只冷门股票

P1有个很有名的股票分析师在他的周刊专栏上推荐了3只冷门股票(平时很少有人买的那种)
P2 杂志上架的前一天， 这三只冷门股票总是被人大量买入
P3 这种模式持续了一段时间
问题让你解释为什么会发生这种现象注意题干有个except， 所以就选那个不能解释的选项。ABCE说的都是： 在杂志上架前，有人能够因为某种原因，提前接触到专栏推荐股票。 所以他们就能够知道那个推荐，然后提前买了。 而D 是无关选项，不能解释。选D

不知道这种在herl怎么分类型（maybe 现象解释型？）。

行素

顶一顶，我也在想你发的最后一题是什么分类。我本来想的是因果，可方案也说得通。就是不知道前面这么多背景介绍算不算论证部分
