Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago. Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water. Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth's saltwater oceans, these species must have had to return frequently to freshwater rivers to drink.

Which of the following is most strongly supported by the information given?

[原创]1/11 SH 二战不利 M51 V29 680

在上海的晚场考试, 虽然感觉做的比第一次考顺利很多, 也不紧张, 但分数还是令人沮丧的.

AA:Apex Manufacturing 给managers 在家办公那题

AI: advancement of  technology and business increase life quality

数学基本都是JJ, 真的很感谢整理JJ的同学们; 以下有一个好像是JJ的变体:

DS: ax^2 + bx +9=0 问是否有确定数量的实数解  1)a<0  2)b=-6  我选C

x^2 + ax +b=0 有2个正数解问下面哪些正确    1)a<0  2) b怎样怎样  3) ab<0  选1,3

还有一题图表题求median number. 只要对应的把数字写出就可.

其他都是JJ 而且答案基本不变,特别是PS 题.

V总体感觉语法很多, 基本都是短句, 有些考点挺迷惑的.

本月的逻辑JJ 要看, 很有用. 做题时会产生共鸣.补充二题似乎没有在JJ看到的题

一道GWD:

Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago.  Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water.  Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth’s saltwater oceans, these species must have had to return frequently to freshwater rivers to drink.

Which of the following is most strongly supported by the information given?

 

A.     Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean.

B.     Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water.

C.     Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water.

D.    The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys.

E.     Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.

另外一题说政府要对香烟加税, 这样实现2个目的: 1是减少香烟的消费 2是增加税收. 问2个目的都不能达到. 我选有些香烟生产商会生产便宜的香烟.

RC 都是JJ,  考到的是夏威夷(第一篇), pain test/distraction, California Children Fund, multicultural multinational

夏威夷是我的第一篇. 估计分数低就毁在它上面了. 选项很干扰. 主题题我选的是提出new technology

加州儿童基金那篇我看到JJ里有问为何与其它州不同,  我的答案与JJ 给的"加州儿童数量多"不同, 大家还是仔细看下.

其它两篇似乎选项都不难, 不算绕. 吸取一战教训,RC JJ 我重点看了GWD原文的题, 其余的大家还是要现场读题.

废话加牢骚(可跳读): 这次Verbal做的挺顺的, 还提前8分钟完成, pace也不算赶, 等待分数的时候我竟然已经准备好了答谢词. 看到分数, 只有一个深深的"Cena!"

现在要安排时间忙工作了, 调整几个礼拜再继续. MBA 不一定是必经之路, 但即使不申请, GMAT, 我也一定要把你拿下.

DS: ax^2 + bx +9=0 问是否有确定数量的实数解  1)a<0  2)b=-6  我选C

请问为什么?

b^2-4*9a>0

为什么要知道 b=-6?
