大家不觉得这道题提问方式很special吗？为什么用“The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that”这么长一句话来提问，而不是简单的“strengthen和weaken”来提问，说明玄机就在这儿提问的句子中！
这句话的意思是：“因为the argument gives reasons to believe下面哪一项，所以导致这个argument非常vulnerable？”这句话提示我们：the argument本身是有问题，有逻辑漏洞的！C选项正提出了这个逻辑漏洞：大家既然坐高凳子是为看名人，怎么会坐坐就走呢？而原文说高凳子让人坐时间不长，明显就是逻辑上的悖论！D选项之所以被排除是因为它引入了新内容:“less expensive meals”, 原文的argument根本就没提meal price类的内容，又怎么可能是由原文argument导致的逻辑漏洞呢

in its class！！！

这道题已知一个两线交点，k线穿原点，可以确定k的斜率，又知道两斜率乘积，不就可以确定另外一条线了么？

关于B，有些科学家说PAH可能来自terrestrial contamination（有可能来自地球上的生命活动）
nonbiological processes是下一个论点的东西，而且是M提出来支持自己观点的。

DO NOT MAKE ANY LEAPS OF LOGIC and DO NOT BRING IN YOUR OWN INFORMATION. Everything has to come from what's written

90＝2x3x3x5
196=2x2x7x7
300=2x2x3x5x5
最小公倍数＝2x2x3x3x5x5x7x7
2x2x5x5构成100，剩下的构不成6

the word "have" in choice (c) creates a slight but noticeable change of meaning (remember that you have to read VERY literally). specifically, it shifts the focus to those fish that have the eggs, i.e., are in literal possession of the eggs. that's not the point of the sentence; the point is just that some fish produce eggs that require months to incubate, whether they "have" those eggs or not.

"making xxxx" is a consequence of the action. If you write "a deal making xxxx", you're implying that the deal is making xxxx at the time of the action described.

E.g., if you write My teenage daughter wears skirts over leggings, exemplifying a trend sweeping the nation, you're implying that the trend is already "sweeping the nation" right now. If my daughter's actions start the trend, this sentence isn't accurate.

"a part of a deal" is CONCRETE, so it stands for the preceding noun.

the death stroke for that answer choice is the 'for protecting' part; that simply isn't idiomatic.
both versions of the latter half make sense - 'against both american and irish competition' is just as reasonable as 'against american, as well as irish, ...'

“”managerial error in estimating the value of firms“”

A哪里不对呢

The in vs. between issue is an idiom. I say differences in X (just one thing) or differences between X and Y (two things). This sentence has one thing: how the two ears hear a given sound. So, I need "differences in." Elim D and E.

some things wrong with c:
* the placement of 'on earth' is just as problematic as in choice a (again, the sentence seems to be saying that residents of other planets disagree with us).

* 'as seen in the rings...' is a modifier that must be placed next to the thing that it modifies, which is 'the rate at which trees grow'. the way choice c is currently written, it says that indications of sunspot cycles can be seen directly in the rings - and it also implies that sunspot cycles (instead of trees) have rings!

A says that tree growth is believed to be a good indicator by people on earth
and finally, yes, 'the rate that' is simply... wrong. things don't 'happen a rate'; they happen at a rate, so that preposition has to stay.
