写机经比考试用时间还长。。。

44. The following is part of a business plan created by the management of the Megamart grocery store.

“Our total sales have increased this year by 20 percent since we added a pharmacy section to our grocery store. Clearly, the customer’s main concern is the convenience afforded by one-stop shopping. The surest way to increase our profits over the next couple of years, therefore, is to add a clothing department along with an automotive supplies and repair shop. We should also plan to continue adding new departments and services, such as a restaurant and a garden shop, in subsequent years. Being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.”

87. “As technologies and the demand for certain services change, many workers will lose their jobs. The responsibility for those people to adjust to such change should belong to the individual worker, not to government or to business.”

Discuss the extent to which you agree or disagree with the opinion stated above. Support your position with specific reasons and/or examples drawn from your reading, your observations, or your own experience.

 

 

 

 

Math

a=2^4, b=2^a, 2^x=a^b,x

选项:2^16,2^18,2^64

我的答案:2^18。(差点选了2^64
   

a=16b=2^162^x=(16)^(2^16)=(2^4)^(2^16)=2^(4*(2^16))=2^(2^18)x=2^18
   

 

 

 

 

50个人,每人选一门,18人选a15人选b10人选engineering7人选d
   
问选engineeringpercentage
    

我的答案:10/50=20%。这道题很简单在蛮后面为什么呢。。。弄不懂
   

 

 

 

 

9-x^2>0x^2-2x-8>0x must be 在哪个范围内?
    

我的答案:(-3,-2)

第一个求出(-3,3),第二个求出x<-2 or x>4。两个并一并。
   

 

 

 

 

一个数列,an=an-2+11,问633是否在数列内?
    

1a1=39

2a2=43

我的答案:A

 

 

 

 

有个人drive from home to library速度是40miles/hourdrive from library to home速度是45miles/hour,求homelibrarydistance
    

1)来回一共用了34minutes

2from home to libraryfrom library to home多用5minutes(这个数字瞎编的但有具体数字)
    

我的答案:D

(1)      S/40+S/45=34/60求出S

(2)      S/40=S/45+5求出S

 

 

 

 

一个人把$1,0001年,annual rater%compounded semiannually,求一年后的利息是多少?
    

我的答案:0.025r^2+10r

1000(1+0.5r%)^2-1000=10r+0.025r^2

 

 

 

 

以下哪个方程在xy-coordinate中的图中只有一个点both coordinates是整数?
    

选项有:y=7/15x(记不清),y=x+1/2y=x乘以根号3

我的答案:y=x乘以根号3

 

 

 

 

游泳池,this side increase 2 feet while other side increase 8 feetthe distance between the two sides is 24 feethow deep is 4 feet away from the deepest side
    

这道题没看懂,乱画了个图用什么相似三角形做的,(24-4/24=x/8-2)算出来x=5也不知道对不对。
   

 

 

 

 

x>y
    

1-x>-y

2x^2<y^2

我的答案:A

1x<y

2x=3,y=4 x<y;但x=3,y=-4 x>y

 

 

 

 

n is even
    

1n+n is even

2n^2+1 is even(还是odd我忘记了。。。)
    

我的答案:B

 

 

 

 

一共100人,more people were born in October than in any other monthWhat is the least possible number of people born in October
    

选项:89101112

我的答案:10(差点选了12)这道题在很后面好像最后12道的样子。
   

9个月,每个月都有8born。另2个月,每个月都有9born。那么October就可以有10born9*8+2*9+10=100

 

 

 

 

10^50-74,求sum of all its digits?

我的答案:440。貌似是我做到的唯一一道上月机经中的题。
   

999。。。992648*9+2+6=440

 

 

 

 

abcd all positiveac/bd < c/b
    

1b>c(好像是这样,总之一个貌似求不出来的条件)
    

2a>d

我的答案:B。(差点漏看了abcd all positive
   

ac/bd-c/b=c(a-d)/bd 因为cbdpositive,那么知道a>d就可以了。
   

 再补两道数学:

有个方形(如图,图传上来了么。。)面积MFQ=MNF+FPQ吗?

1MQ=2MN

2MNPQ是平行四边形

我的答案:B

 

有个圆锥,求高h

1s=6(总之是个具体数字)

2)底面周长80pai,离底面4的地方周长45pai

我的答案:B。相似三角形做的。

有一道做过,我找了下:
   

In 1960’s studies of rats, scientists found that crowding increases the number of attacks among the animals significantly. But in recent experiments in which rhesus monkeys were placed in crowded conditions, although there was an increase in instances of “coping” behavior-such as submissive gestures and avoidance of dominant individuals-attacks did not become any more frequent. Therefore it is not likely that, for any species of monkey, crowding increases aggression as significantly as was seen in rats.

Which or the following, if true, most strengthens the argument?

A.      All the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions.

B.      In the studies of rats, nondominant individuals were found to increasingly avoid dominant individuals when the animals were in crowded conditions.

C.     Rhesus monkeys respond with aggression to a wider range of stimuli than any other monkeys do.

D.     Some individual monkeys in the experiment were involved in significantly more attacks than the other monkeys were.

E.      Some of the coping behavior displayed by rhesus monkeys is similar to behavior rhesus monkeys use to bring to an end an attack that has begun.

我的答案:C

其他CR题记不清,且不保证做对,因此不拿来误导大家了。。
   

 RC

 RC

有一篇:Black Americans(长,难)
    

第一段:二战时black civil right有提升,因为wartime时候需要很多labor。然后说了怎么提升。Black vote right也多了,在北多2倍,在南多4倍。
    

第二段:继续说black 受待遇更好了。列举了一点。其中有一句说到Black contribute to NAAPC (一个组织)membership
    

第三段:However,在战争还没结束前还是有conflicts and tensionsprotest of civil right还是有,就像end of 1960s一样。比如racial segragation,等。
    

 

以下两篇可能有点混了。。
   

有一篇:consumption的什么
    

第一段:很多人都只考虑purchase不考虑consumption。但postpurchase(即consumption)也很重要。
   

第二段:有很多conditions会左右consumption,比如time, complicity, ease of preparation。。。(列举了有考点!
  
但有些小的大的无区别,举例泡咖啡都要spoon, cup, water。。。(这里考了个类比题)
   

 

 

有一篇:pricing the new products
    

第一段:以前是stable priceHowever,现在有两种1skimming 2忘了。。
   

第二段:现在的trend主张用某种(我的理解指skimming)。但它对high的比low的更好。然后只要low的能在一开始就occurlow还是能一直延续下去的。
   

考点:主题题 / high & low

  

  

有一篇:CO2

第一段:有种技术可以capture CO2然后储存起来。这种方法虽好但找不到地方储存CO2。科学家们考虑了AB两个地方,但它们都太小了。于是科学家们又开始考虑deep ocean
   

第二段:deep ocean也有问题,因为历史上发生了件事在某地的CO2离火山近,最终使火山爆发了。(暗示deep ocean也有可能有此类问题,考点!)很多公司还是会出于economic incentives(考点!)的原因选择不用这种技术,因为把CO2排到空气中没人知道。
   

 

 

SC

有一道,using A reducing B,应选reduces。其他记不住。
