A they 和 their指代不同， primarily 修饰位置错误
D E and 和 as well as 前后不平行

看懂题目意思很重要：黑洞存在于银河以及其他许多星系的中心。

错选A, A与题干中的the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office说法好类似，所以应该不是答案，重复前提没用

果因推理

方案推理，A CQ3: 方案的副作用

C中 that不就指代conversation了吗？？？

如果选项中说方案无法实现 会不会造成因为“抬扛” 而成为错误选项而不是削弱选项呢？

What is striking about these lizards is not that coexisting species differ in morphology and habitat use (such differences are common among closely related sympatric species), 可以从这里定位

(2）（30+20*X)/x=30 所以条件2单独成立

that 作为定语从句引导词 前面竟然可以有逗号？？

要是是中文的话是个人都能做了，我透

reflected a general optimism concerning IT's potential as a resource for creating competitive advantage.>>>從這句改寫成 ＯＡ：Ｅ
A belief in the likelihood of increased competitive advantage for firms using IT

最后一句是have wondered whether, 表示尚未有确定的解释

inhibited

生产商----》零售商-----》客户。生产商并不直接和客户有关，生厂商的利润多少只和零售商行为有关。D的意思是：零售商会乘着生产商打折的时候大量购买存货，之后却依然以正价卖给客户。导致客户并不能获利从而不会提升客户的购买量。相比之下，如果生产商直接按原价销售，客户也是按原价购买的，购买量不变。则后一种情况下，生产商反而能赚更多钱。（好几道题有考到类似这种生产商到零售商到客户之间会出现不均衡的状况的题目了）

partly responsible 保险只是部分责任，不是全部责任，就说明确实有其他原因也导致银行破产。则D已经属于题干考虑过的内容了，不能再考虑。

错选D，发现有个解释的很到位
This suggests that the independent suppliers are in a position to offer these services at a lower cost. But during the bidding process, there is no certainty that the lowest bid will ACTUALLY be lower than the cost incurred by Vernon. It may just be the lowest of all the bids, but not necessarily lower than Vernon's own cost.

题目没说只有两类…可以自己推测吗？

Researchers also measured land-tenure security: in Tawahka society, kinship ties are a more important indicator of this than are legal property rights, so researchers measured it by a household’s duration of residence in its village. They found that longer residence correlated with more adoption of improved plant varieties but less adoption of chemical herbicides.
注意不是支持它的assumption是什么，而是它reflect了什么

qualify词义理解错误，表示限制限定，在这里对应原文中的exception
