对 假设有100人

直接试错，N=2D，从C开始试错
1/D+1/(D-2)=5/4
比如E, D=6
结果是对的

化简成2的根号形式，根号2等于1.414...

economic development, particularly industrialization and urbanization, contributes to the growth of participatory democracy

However, the economic development theory is inadequate to explain certain historical facts about the implementation of women's suffrage.

painstakingly修饰document这个动作，指记录过程很辛苦
painstaking documentation辛苦的记录 不合逻辑

我的一点愚见 做题是比如刚开始的比较实在搞不清就先看后面的内容 raise点入手 a选项有个therefore 所以价格上涨的事件发生在前面事情之后 有个逻辑关系 所以raising 能表达出一个因果关系 因为前面比较的话 有一道题就是Heating-oil prices are expected to be higher this year than last就是正确的 这个时候的确不敢排除了

tigers are merely Indian tigers—a subspecies well represented in both zoos and the wild—and that zoos should focus their tiger management efforts on preserving subspecies whose existence is threatened

It is true that Switzerland's urbanized cantons (political subdivisions) generally enacted women's suffrage legislation earlier than did rural cantons. However, these cantons often shared other characteristics—similar linguistic backgrounds and strong leftist parties—that may help to explain this phenomenon.

根据条件二：
5（S1+S5）=7(T1+T7)=>5(S1+S1+4)=7(T1+T1+6)=>5S1=7T1+11
1) 当T1=-3时，S1=-2
2) 当T1=-8时，S1=-9

所以，条件二单独不成立

结合条件一，如果S的中位数是0，则，S序列为：-2，-1,0,1,2

得出， T1=-3，S1=-2，T和S序列都已知。

* first, the tenses should be parallel, since the descriptions are meant to be simultaneous.
* second, they should be the present tense, since the sentence is stating facts that are statistical truths.

earned at a time ... 是否为定语从句修饰record？完整应为which were earned at a time
请老师回答？

毕老师，我想杀G成功，可是考了两次分都很低，买了你的书，但是做题还是错，不知道怎么办，真的很想放弃需要gmat的学校了，在职工作很受伤。

Mark。在选项间纠结South/North的时候，忘了是去加强还是削弱了，导致选了E（虽然A也削弱）。C选项取非一下，还是还是很好懂的，但感觉south/north还是有那么一点值得商榷的余地

错选D Such a dramatic increase in straying from damaged areas to more pristine streams results in substantial gene flow

收下我的膝盖。。。子集 我都没想到过

求解！

想请问A为什么错呢 看到OG上的解释是[giving...]的部分illogically modifies the whole preceding clause, rather than [satellite]. 但是giving 的逻辑主语不是应该是a new satellite吗？ 谢谢大家了
