Chasedream has been my best friend over past two months, I visited her very day and benefit a lot, now it's the best time for me to do something for her. Here is some JJ: AA: Apogee company's profit has been increase since operated in the one location, therefore company should close all the field offices in order to cut the cost and improve the profit. AI: MultiInternational company lead the global homegeneity, people everywhere want the same products and same service. RC. Technonationalism ( same as in RC jj), Power station produce aero?(some kind of chemical stufe pollute air), instead causing global warming this stuff make earth cooler. MM. lots of JJ, relatively simple, no super hard questions. 7个柜子3个5米的，2个4米的，2个3米的，罗三堆，问least possible height of the highest pile.
KEY 10 是一个直角坐标轴，上面有一个直角三角形，直角顶在原点，两条直角边分别是x轴和y轴，长6，高4，现在有一条y=c的直线把这个三角形截成两段，面积相等，问你c=? 42，DS:有一个can高5inchs,有一个box,体积为12feet(1foot=12inchs)，问能装几个can？ （1）a dimension of the box is 多少feet(忘了) The one I have is one side of the box is 2 feet.
（2）can的直径是3inchs
I choose E
5，一个学生组织有10个人，选举3个管理层，第一个当president, 第二个VP,第三个assistant还是什么的，问有几种可能性？
74，大意是，在x y象限有两点，（-1,3）(2,-1),如果这两点是一个长方形的对角线（注意对角这个词：diagonal）
104，一直线上面有3个半圆，分别直径是3x，2x，x，问lengh of this curve This question ask you to calculate the chord of three half circles, their dimentions are 3x, 2x and x respectively, the answer should be 3xpie (sorry don't know how to write the equation)
150，商品价格x第一次涨价，涨了r pecent,第二次涨了y,问两次一共的increase占x的多少， 注意问的是increase，不是涨完的总值 , The one I have is first increase by x%, second increased by y amount, ask total % of two increases.
The mouse one, the graph is like following: x x x x x x x x x x x x x x x The mouse start from top, goes down ask you how many way for mouse to get to the bottom.
