5/28一战餐具，上寂静

ffffighting

当语法根本不再有平行、主谓等等一系曾让我激情的考点
当洛基只有削弱和加强
当最后一篇岳毒只有半屏
就已经预料到了最后的结果...平静地走出考场，终于在车上给爸短信报丧的时候眼泪决堤...

上狗
AWA
Argument: East Cambria的vonlunter ambulance service的average response time比West Cambria的commercial ambulance service长。为了给病人更好提供服务并且通过收费获得revenue，East C应该把vonlunter ambulance service撤了全部换成commercial ambulance service。

Issue: 大意是to achieve professional success会sacriface the fulfilling of personal life

Q：我考前看了二十几道机经就有几道考到了，不难我就不写了，eg. {x}的，韦印图的
X、Y是整数，问24X+15Y可得出的最小正值。选项有1，3，6，9，15
这道记忆最深，我选了3，自认为小学初中数学学得很好，但仍不知道对不对。

m,p,s,v正整数,m/p<s/v ，问哪个必在m/p与s/v之间？只有I.必然对
I. (m+s)/(p+v)
II. 暂时想不出，不过很弱智的一看就知道不对
III.  s/v-m/p

问(1/25)^3=? 选o.oo8^2。
话说好多这样简单到要哭了的题，我就不上狗了。

500个不同的数里比153.7小的有76%，问100是否比median小？
(1) 大于100的数中有60%的也大于153.7
(2) 大于100的数中有40%(具体比例我忘了)的小于153.7
选2个都sufficient

5个不同的整数，平均数为60，其中最大的为100，问median最小可能是多少？选33

Verbal
我就是个大杯具啊，只有低分狗了
CR    有碰到大概3-4道GWD或PREP的变体（GWD我只做了10套以内，PREP只做过老版的CR1）！
变体1. sea otter数量下降，判定原因为killer whales。killer whales捕食seals and sea lions（数量貌似也减少），但很少很少捕食sea otter。问解释

又想起来一到变体，在原题基础上略有小小改变，但是实在想不起是GWD哪套了，望各位大虾能帮忙找找~
变体2. 某种鱼类数量decline，是因为船速太快，容易与相撞。当地已有相关规定船只应减速，措施有效，因为鱼数量increase。问evaluation
只记得一个选项：Whether那些被撞的鱼正在mature的年龄。完全忘了选什么了。

深夜中又大概想起一道
某监狱里有个program，貌似包括一些娱乐等措施（？不确定）。说这个program不好，因为入狱的人变多了。问解释或加强（真的记不请了）
我选的是最有喜感的选项：入狱waiting list的人争着要加这个program。

SC，原本是我的强项啊，今天考到的感觉没啥语法点啊！
最荒谬的一题是：If you blablabla（没仔细看）, please let me know and I would(and I would划线) prepare a copy（貌似）. 真的懵了，这破题在考什么啊！搞到我犹豫了，最后选了so I can。哎杯具...

RC，之后考的筒子们，阅读寂静还是有必要看的哎~~
1. 蜜蜂那道（Pudgysphere同学上午考完讲给我听了，可是我居然没仔细看哎）
2. 长的，容我想想
3. 长的，再容我想想
4. 超新星辐射的（天啊我发现我和Pudgysphere同学抽到2篇一样的阅读，两人都杯具了）
   1、4两篇大家参考Pudgysphere的帖：http://forum.chasedream.com/GMAT_Math/thread-462043-1-1.html

困死了，我睡睡，想起来再补充吧...
这个分真的没脸见人啊，在公交车上哭得梨花带雨，悲情啊，不知道怎么跟大家交代，对不住大家的关心...
感谢一路支持我的人虽然对不起你们。等我二战凯旋吧！

P.S.特别感谢Pudgysphere，认识没多久但是很感激。你那句No matter what, tomorrow is another day是我们俩天涯沦落人的内心写照，搞到我不争气地猛掉眼泪。还有下午那句“你不是我，我没考好跟你没有任何关系~不要紧张，好好发挥~”，除了感动我不知道还能说什么。

Any way, it is a new divide!

搞得我都不好意思了

...虽然我也没太睡好，但你这个早上两三点钟发帖实在是...

身体是二战的本钱，再说期末考试也近了，要休息好丫～

同是天涯沦落人～我当时也忍不住掉眼泪了，加油，一起准备二战吧～

lz lz, 这道题不会做。。。
500个不同的数里比153.7小的有76%，问100是否比median小？
(1) 大于100的数中有60%的也大于153.7
(2) 大于100的数中有40%(具体比例我忘了)的小于153.7
选2个都sufficient
解释一下吧，谢谢啊

我觉得是，
(1) 因为大于153.7的有24%，而大于100的数中有60%的也大于153.7，所以说明大于100的有24%/60%=40%，即100比处于50%位置的median大，sufficient
(2) 同理，大于100的有24%/(1-40%)=40%，仍然sufficient
应该没有理解噢

14.再见sea otter
V1 from cytlc1978
sea otter那题，原题问weaken，我考的这道问support，题干略有变动，选项跟原题完全不同
V2 from xzbest
otter数量下降，与此同时seal数目上升。Seal是被killer-whale吃的。说whale数目增加，又说seal怎样怎样，所以说otter是被whale吃了。问啥忘了。。
V3 from qq309790244
kill whale：seaotter数量减少。report说sealion 和seal也下降，killwhale吃sealion和seal，但是报告说killwhale吃seaotter  is rare，但在1980前根本没有报告。所以seaotter下降是由于killwhale。问支持
GWD原题：
GWD-8-Q3:
In the late 1980’s, the population of sea otters in the North Pacific Ocean began to decline. Of the two plausible explanations for the decline—increased predation by killer whales or disease—disease is the more likely. After all, a concurrent sharp decline in the populations of seals and sea lions was almost certainly caused by a pollution-related disease, which could have spread to sea otters, whereas the population of killer whales did not change noticeably.
Which of the following, if true, most seriously weakens the reasoning?
Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey.
There is no indication that substantial numbers of sea otters migrated to other locations from the North Pacific in the 1980’s.  
Along the Pacific coast of North America in the 1980’s, sea otters were absent from many locations where they had been relatively common in former times.
Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters’ main food source.
The North Pacific populations of seals and sea lions cover a wider geographic area than does the population of sea otters.

Babee2queen: Sea otter在六月机经里出现过加强的版本：
C）seals and sea lions的食物大量减少，但是sea otters的prey没有减少（正确答案）
e) 在kill whale到不了的bay的sea otters数量和kill whale到的了的数量都减少了。

Babee2queen: 从V2V3来看，和GWD原题差异比较大；大家认为C的答案很靠谱，排除他因

跟qq309790244说得大概一致，但是一下子想不起是问解释还是支持了...

再次感谢lz..
再次。。汗 还要麻烦下。。确认下sea otter的那个。。
第一页有两个版本的。一个z同学的还一个是我的。请问哪个更接近？
谢谢谢谢

监狱那题没有找到考古资料==
lz那个监狱的有没有 college-level courses 这种字样？

没有，之前没碰到过，突然想起来有blue jeans字样~~

lz是这个不
8: GWD-29-Q9
Manatees, aquatic mammals inhabiting Florida’s rivers and coastal waters, swim close to the surface and are frequently killed in collisions with boats.  To address the problem, boat traffic in manatee-populated waters is being required to maintain very low speeds.  Unfortunately, manatees are unable to hear low-pitched sounds and a boat’s sound lowers in pitch as the boat slows.  Therefore, this approach may in fact make things worse rather than better.
Which of the following, if true, casts most doubt on the conclusion?
A. The areas where boats would have to maintain low speeds were decided partly on the basis of manatee-population estimates and partly from numbers of reported collisions between manatees and boats.
B. Because the water hyacinth that manatees feed on grows best in water that is nearly still, water hyacinth beds can be disturbed or damaged by fast-moving boat traffic.
C. Over the last several decades, boat traffic in Florida’s coastal waters has been increasing almost continuously and now represents the greatest threat to the endangered manatee population.
D. The sound of a boat engine generally travels much further under water than it does through the air.
E. When experimenters exposed manatees to the recorded sounds of boats moving at various speeds, the creatures were unable to discern the sounds over normal background noise.

对就是这个的题干，细节有变动，选项基本改掉了。谢谢nowwsy~~
