标题: 6.8下午场二战未分手

【坐稳】

Jamjet公司近些年收益下滑，但其他一些在这个行业中lead的公司业绩却很好。J认为是因为他们采用temporary workers来代替full-time workers的原因。同时因为temporary workers的工资更低，所以可以减少workforce cost。所以J决定立刻switch 25%的员工totemporary workers。

思路：错误类比，别的公司与J情况不一样

因果关系错，不一定别的公司就是因为这个switch才有profit增长的

Switch有隐形成本，比如高频率的培训成本，也有产品质量下降的风险，所以cost可能不减反增

【艾阿】

1. 记得一个类似股票K线图的三家公司A.B.C 它们在进行一个比赛

图给了每日股价线和1/2股价线还给了平均股价线

如果公司有至少一天的股价的1/2高于另外两家的普通股价得1分

如果公司有至少一天的股价是所有公司里最高的得1分

如果公司有至少80%的天数的股价都高于其他公司的股价得1分

如果两家公司平局（tie）,则平均股价更高的获胜

问：哪家公司以多少分获胜

2. 有四个系统文字很多介绍了各种系统的长处和短处可以自己画个表格记录一下然后问哪个性能被最多的系统作为优点哪个性能被最多的公司作为缺点数一下表格里记得就行

【输血】

感觉有超多都是机经里的…我就不重复了，补充几道：

1. (5！+6！+7！)/（6！+7！+8！）=？

算出来的答案跟选项不一样...就瞎选了一个

选项：A. 1/2000多

B．1/300多

C．49/300多

D．5/8

E. 6/7

2. 一个花园是一个等腰三角形腰长13feet 底边5feet 要在花园铺1inch厚的什么东西，问铺的东西的体积是多少cubic feet。涉及单位换算

3. 一年下来投入X本金到2%单利一年期产品的利息等于投入10000到年利率8%复利半年付息的一年期产品的利息问X是多少

选项有20200 20100 20050之类的

4. AB两组数都包含20个元素 A集合的平均数大于B集合的最大值，问哪个对

I. A集合平均数大于B集合平均数

II. A集合中位数大于B集合中位数

III. A集合极差大于B集合极差

5. 问下面哪个X值可以使得一个分数代数式最小具体代数式忘了但分子是一个含X的绝对值的（好像是x-1/2的绝对值）所以选使这个绝对值等于零的X值答案是1/2

【逻辑】

换火车的那个(80换到125但铁轨只能承担80的那个)，问削弱，确定选有很多mountains导致火车都不能达到最快速度，因为题目中结论说的是不能缩减每个trip的时常，而维修那个选项说的是trips之间的维修次数。

对了有一道是练过的PREP原题：

Paleontologist: About 2.8 million ago, manyspecies that lived near the ocean floor suffered substantial populationdeclines. These declines coincided with the onset of an ice age. The notionthat cold killed those bottom-dwelling creatures outright is misguided,however; temperatures near the ocean floor would have changed very little.Nevertheless, the cold probably did cause the population declines, thoughindirectly. Many bottom-dwellers depended for food on plankton, small organismsthat lived close to the surface and sank to the bottom when they died. Mostprobably, the plankton suffered a severe population decline as a result ofsharply lower temperatures at the surface, depriving many bottom-dwellers offood.

问的是第一句和Nevertheless那一句的作用

剩下好多都是jj原题 jj解释得很详细了感觉这次运气挺好，中了超多jj，但还是没能顺利分手…实力还有待提高

【粤独】

第一篇ceramic界A.O.这个人的贡献被忽视的那一篇我的最后一段是说A.O,服务的那个流派后来被rejected了，有一道题问最后一段的作用，我选的说明A.O.所在的这个流派最后不是人们的favor了

第二篇是泰勒管理办法，虽然之前看了jj，但感觉还是不太懂…感觉很专业

第三篇是脊椎动物呼吸的跟jj一样最后一段有些难，重点看

第四篇是关于企业集中在一个location的，好像之前练过类似的，不难理解。第一段说了集中的好处，第二段开始说集中的坏处，会增加竞争和资源变得匮乏等等，第三段讲了对进入壁垒的影响，全文总体说坏处。挺简单的。

补充一下。第15题是PREP原题。
但 PREP原题里面问的不是第一句。我把原题和解析贴过来。大家也看看吧。
Paleontologist: About 2.8 million years ago, many species that lived near the ocean floor suffered substantial population declines. These declines coincided with the onset of an ice age. The notion that cold killed those bottom-dwelling creatures outright is misguided, however; temperatures near the ocean floor would have changed very little. Nevertheless, the cold probably did cause the population declines, though indirectly. Many bottom-dwellers depended for food on plankton, small organisms that lived close to the surface and sank to the bottom when they died. Most probably, the plankton suffered a severe population decline as a result of sharply lower temperatures at the surface, depriving many bottom-dwellers of food.

In the paleontologist's reasoning, the two portions in boldface play which of the following roles?

A. The first introduces the hypothesis proposed by the paleontologist; the second is a judgment offered in spelling out that hypothesis.
B. The first introduces the hypothesis proposed by the paleontologist; the second is a position that the paleontologist opposes.
C. The first is an explanation challenged by the paleontologist; the second is an explanation proposed by the paleontologist.
D. The first is a judgment advanced in support of a conclusion reached by the paleontologist; the second is that conclusion.
E. The first is a generalization put forward by the paleontologist; the second presents certain exceptional cases in which that generalization does not hold.
答案是 A
