作文：不记得jj里面有，我找出了原题;
The following appeared in a memo to the Saluda town council from the town’s business manager:
“Research indicates that those who exercise regularly are hospitalized less than half as often as those who don’t exercise. By providing a well-equipped gym for Saluda’s municipal employees, we should be able to reduce the cost of our group health insurance coverage by approximately 50 percent and thereby achieve a balanced town budget.”
Discuss how well reasoned . . . etc.

reviewer JJ第46题，给的信息太多，都是文字描述，感觉脑子完全转不过来。花了十分钟还是放弃了。
只记得题目：
哪个不可能是作者?
哪个不可能是primary?
2. two part analysis
基因RNA有4种碱基A,B,C,D,一个基因片段由8个碱基组成，从这4种碱基中各取2个。
在一个由这种基因片段组成的所有可能组合中，随机截取最后2个碱基，下面是问题:
左边一列问最后两个碱基相同的概率，右边一列选最后两个碱基不同的概率。
1/7, 6/7, x/28, ...数字不记得了。这题读懂意思耗时，计算我也做不出来，最终放弃了。
数学：
提前7分钟做完。最后一题我故意不点确认，给自己5分钟时间休息，然后确认。
1.
f(x)=7-x 当 0<=x<4
f(x)=x/2 - 2 当4<=x<=6
问：当f(x)在什么区间时，x的取值范围是0<=x<=6
我选的是当f(x)在[0,1]和(3,7]，是否包括了端点，我不记得了。
