E选项：介词短语with higher-than-average blood pressure和with a history of high blood pressure running in their family之间缺少连词连接，正确方式为：
young people with higher-than-average blood pressure and with a history of high blood pressure running in their family are more likely than others to develop a severe form of the condition.

C 文章中未提及

A: as a result of several improvements和because coal replaced charcoal as the fuel used in the smelting of iron ore并列。语法上是可以的，因为两者都是原因状语

错选C：文章说的是Krech also contradicts Martin's exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene.就是说K认为M不该排除天气变化是灭绝的一个原因，因为K认为波及范围广的天气变化确实在end of the P的时候发生了。
那么答案说Additional evidence indicating that widespread climatic change occurred not only at the end of the Pleistocene era but also in previous and subsequent eras. 其它时候有没有发生和end的时候有没有发生无关。

文章：small animals, plants, and insects disappeared, presumably not all through human consumption。 并不都是

最小公倍数就是取最大指数的质因数

3/3*2/3*1/3=2/9
3*2*1/A33

用时太长了！考试估计要直接跳过了。图太有误导性。利用了等腰三角形底边高与底边中分线是同一条线的性质，所以AC和CE在一条线上。BD垂直AC，所以直接底乘高除2 可得

感觉E，C更像是只是重复了前提。E是将更不关注钱和解题时不合作/求助建立因果关系，也正是结论想说的

太难了这套

是因为so可以指代句子，it只能指代名词吗

难道是因为问题里面用了"separately supported..by passage and 2 tables"? 所以虽然passage是完全support的，但是table里面完全没有涉及，所以只能选No？

生厂商白嫖了兽医提供的有效的营销渠道，但是兽医没有得到全部好处

为什么很多好的题目都没有讲解。。。。。。烦

C选项为什么不对呢

prove主动被动都对
有时间终点用名词形式，否则用动名词形势

that statistic would be what we would expect even if volunteering does not boost longevity就算是志愿工作不能导致人们长寿，这个数据也依然会是这样。

C 方向反了。。

md把句子都完整啊giegie

没有想到利用边长比与角度比的关系

题目没读清楚，题干没说买了几个D和几个C,求的是买了几个D。。
