类比推理 => 寻找lab中合成的东西和nature产生的东西的区别

弱弱问一句，it is ...that..不是强调句吗？BCD的主语不是应该还是none吗？

Although no systematic evidence exists to determine unequivocally whether smaller units of production are as efficient as large firms or are, 后面半句in fact, more efficient, some researchers have concluded that the accumulated evidence to date indicates that small firms are at least not burdened with an inherent size disadvantage 说了More efficient，为什么不对呢？

因果推理, 找反驳结论(果)选项, (C) CQ2：因果联系问题

第一次做题的时候做错了，因为错误的判断 at least some 语气不够强。
其实在Assumption题目里，some 的语气才强。OG里面介绍的Assumption题做法是把选项否定掉，看选项是不是削弱项。
否定some，就是not some，就是all。而否定most，就是not most，就是some，反而语气更弱。
有的时候这一点也是要主意的。

总而言之，做Assumption的题目，一定要按照削弱的思路来做

1) Based on XXX, Subject + Verb. (修饰Subject). 修饰后面的主语
2) Subject + Verb + Object based on XXX. (修饰前面的object) 修饰前面的宾语
3) Noun is/was/are/were based on XXX.

方案推理, 答案必提及方案, 故(A)(D)(E)排除; (C) = CQ3：方案的否定性副作用

In these tropical regions, diurnal(daytime) visitors to columnar cactus flowers are ineffective pollinators because, by sunrise, the flowers' stigmas become unreceptive or the flowers close. Yet the flowers of the Sonoran Desert cacti have evolved to remain open after sunrise, allowing pollination by such diurnal visitors as bees and birds-答案e从yet后半句来

with the goal of
2,620,000 results on the web

with the goal to
639,000 results on the web

the goal of is more idiomatic

ultimately的位置比起goal to更好判断
我甚至认为goal to xxx没啥问题。。。

只能说其他选项错的更离谱了？

"Former" is exactly like "ex-", so maybe that will help you understand.
Let's say some male executive, Harold, was married to a woman named Sherry, but they've divorced. In this case, you can probably understand why this sentence is nonsense:
As Harold's ex-wife, Sherry entertained many of his clients in their country home.
Clearly it should say "As Harold's wife". (Unless these two were very weirdly close after their divorce.)

老师你好。e为何不对呢？原题的逻辑是：65岁以上的比24岁以下的出事故少，所以推出年纪大的比年纪小的开车更安全。但是如果30-40岁阶段的事故更低，那么结论就不成立啊。所以其他年纪也没有比65岁出事的多，才能得出这个结论吧。

主谓一致；时态平行

appreciative 欣赏的、表示赞赏的，干掉AB
E: the river resulted from : resulted from成了river的定语，错
C: the use would continue to be restricted contnue to do 中间可以中断，然后继续
D：restrictions continue 中间没有断过，持续的，与从句中的not increase相对应

A和B无成分差异，B 错在时态不应该用过去时，时间状语是over the last several months，应该用完成时

B和C，C 没有表明是避免谁被偷

A和E ，A里的in two letters 位置不好，变成了 eruption 的定语

game不能proclaim，所以B不对
