that 引导同位语，AB错
E的主语不对，应该是Ban而不是state laws
CD区分：
C中，违反是现在时，允许是过去式。如果“过去”允许而“现在”不允许，那么就不需要“现在”违反了，所以错误，应该两个都是现在时。
D用doing解决了这个问题

句首doing， 主语应该与doing一致，ABC不对
前后句意是并列关系，所以D不对

AB是没有谓语的问题
CE有it 和them不一致
D这里to do 是目的状语？

虚拟语气

the remainder of the increase 【coming from sales of the 9,850 prescription medicines】
n +ving 形式独立主格

for doing表示已经发生过的事情（原因），而to do表示还未发生的事情（目的）；鉴别主句开始发生的时候，这件事是否已经发生了即可。若已经发生，则用动名词形式；若尚未发生，则用不定式的形式。

看漏了未划线部分的both

smaller与less distinctive， less in demand平行

考察评估的这个economic viability 是个比较值

Ron's explanation here: in this case, the problem is saying that solar power has gotten more efficient, but also that there has been no change in the target price of oil to achieve price equity with solar power. the only way this can be true is if something else related to oil-driven power, aside from the actual price of oil, has become cheaper in line with the improvements in solar power.

C says that advertisers of OTHER cookware brands (who will now be competing with the Kitchen brand) may not want to advertise in Kitchen magazine anymore since Kitchen is now a competitor. If Kitchen loses this advertising revenue that would hurt the revenue stream and certainly make the conclusion wrong. Thus, we have to ASSUME that this will not happen if Kitchen begins to put its name on cookware.

1) n is a multiple of 5.
(2) n is a multiple of 12.
把n带进去看。

若选项取非，可以削弱原结论的话， 则代表选项其实是增强原结论的；反之亦然

顺序的因果逻辑：因为虫害导致棉花最近价格上升，所以种植棉花可以上升收入
（因）前提：棉花最近价格上升
（果）结论：种植棉花可以提高收入

C选项为充分不必要条件

e, had been时态不对，转折意味but更好

两个并列的不可数名词作主语时，其后的谓语动词通常用复数，有时也用单数。
　　使用原则：
　　1. 如果两个不可数名词是指两样东西，则谓语动词用复数；
　　例：Coal and iron are minerals. 煤和铁都是矿物。
　　2. 如果两个不可数名词是指同一事物或同一概念，或因其紧密相关而被视作一个整体，则谓语动词用单数。
　　例：Trial and error is the source of knowledge. 反复试验是知识的源泉。

错选了D，The author provides evidence that seems to support a position held by critics of Melville but then demonstrates that the evidence actually supports a diametrically opposed position.作者提供了一颗看起来支持批评家的观点的整句，但是之后证明了这个证据实际支持一个完全相反的观点。完全相反的观点在哪里？

former以前和现在无关

这道题错选了A
题目：The author draws which of the following conclusions about the fact that Melville’s fiction often does not possess the qualities of a Jamesian novel? 作者基于M小说不具备J小说的事实得出以下哪个结论？
事实就是ALTHOUGH让步状语从句中说的这一句，结论是从句之后的主句，以及主句之后的解释。结论中从未提及literary critics干啥干啥啊？！
