AWA

ISSUE: In order to preserve the national security, government should be authorized to do......they wish.(不好意思，表述不完整，大致意思就是出于国家安全的考虑，政府应被授权采取任何措施)

Argument:

The following appeared in a letter from a part-owner of a small retail clothing chain to her business partner:

“Commercial real estate prices have been rising steadily in the Sandida
                 Heights neighborhood for several years, while the prices in the adjacent neighborhood of Palm Grove have remained the same. It seems obvious, then, that a retail space in Sandida
                 Heights must now be much more expensive than a similar space in Palm Grove, which was not the case several years ago. So, it appears that retail spaces in Sandida
                 Heights are now overpriced relative to those in Palm Grove. Therefore, it would be in our financial interest to purchase a retail space in Palm Grove rather than in Sandida
                 Heights.”

Discuss how well reasoned . . . etc.

verbal:

CR:

1.一个政府靠卖烟草赚钱，但是烟草盛行使得health care的费用增加。有人建议禁烟，但是建议没有被采纳。问其中的assumption（补充：题干中讲到：政府财政收入有大部分是来自烟草税收。）

RC:

1.加州妇女育儿组织 JJ文章内容讲的非常详细，题目也解释足够清楚

2.measurement bias 这篇文章总体不难，题目也较简单

5、6、7的答案是不是：E B D？

5.DS：n是一个100-1000的数，问会不会它其中有一个digit肯定大于5。（1）n/45>10 (2）n/5>100

这个选E么

7. DS: m的n次方是perfect square?

（1） m是perfect square

（2） n是perfect square

这个选A？对么

8. 一组数列，1，11，111。。。，（第n项有n个1），问前40项的和的十位数是什么

这个答案是3？有人有其他答案么？

10. 老鼠按照一个模式走路，就是从一个点开始分支两路到下级两个点，然后再下级就是三个，再下级就是4个，整体路线就是像金字塔那样大家意会啊，然后说老鼠从最初的一个点走到最后那一级有多少种不同的走法。

答案有：4^6, 3^5, 20, 45, 还有的忘了，这题当时没算出来和答案一样的蒙了一个。

题目的基本意思如前人JJ所述，我觉得这道题值得讨论，JJ总结中的答案“24”，选项中没有“24”。我也没做出来，蒙了一个“4^6”，估计这道题肯定做错了。希望高手指点。

这个题目我觉得是假设是N级，那么一共有N!走法。如果N=4,那么4! = 24

对么？

JJ整理的不是说选C吗

我遇到的JJ题目，请参考“数学JJ总结”的答案。感谢贡献和总结JJ的战友！
