错选C，C是两个人都同意的观点

理解题目意思：抽出一张卡片，卡片上的数字为x，（x*x+1）始终在15，200之间。

which不能修饰整个句子！

感觉b里面的that try也有问题，try的发出者不能是innitiative应该是company

CHOICE A-run-on
CHOICE CDE- 'scale of' doesn't make sense
CHOICE C- you can't say 'each that had...' (can't follow 'each' with a relative pronoun - if you're going to use a relative pronoun, it has to come directly after the thing it's trying to modify)
CHOICE CE- no justification for using the past perfect ('had been') - that verb, if there's a verb there at all, should be in the simple past (the same tense as everything else in the sentence, because everything described in the sentence is contemporaneous)
CHOICE CE- it doesn't make sense to use 'each' AFTER the comma, because it's not true that each structure was connected with a road system. instead, the road system connected all of the structures with each other, which is nowhere close to the same thing. (having 'each' BEFORE the comma makes sense, because it's actually true that each of the structures comprised up to 600 rooms.)

错选B：不需要考虑政府的总债务，仅需考虑the debt accumulated in acquiring and storing it.
E错的原因：不需要考虑closing之后的成本，因为题干问的是by selling the helium.

提供了一个衡量标准（衡量人类活动对鲑鱼gene flow的影响）——他们没有qualiative difference

1973 to 1993, during which 会导致which引导的定语从句优先修饰1993，然而应该修饰整个时期，用an era during which会更合适

先快速定位discrepancy的位置与具体内容：physicians believe... requirements prevent them from spending enough time with patients ; VS "average time a patient spends with a physician during a visit has actually increased";
结合材料中提到的require physiscians to document their decisions, 发现B选项内容接近

B选项错的原因是no known... that indicate the structure of those dinosaurs' lung是原文中没给出的内容，原文说could not have evolved the complex lungs，选项过度解读了

1. scale of structure make no sense , "scale of 1 to 10" is ok 排除cde
2.a 两个动词之间没有连词 排除a

正确选项A的意思是：作者没有充足的评估是否取消这个禁令之后的影响——Pat认为工资上涨有改善状况，原因是很少的人讲课教书，但他是建立在认为ban对他们讲课教书的意愿影响较低的情况做出的猜测——实际上取消了禁令后可能会有很多人参与讲课教书

on the amount of sales over (注意这个over，说明只考虑超过这个数额的部分)

the core of the sentence is
“a bird has colors.“
both 'found in the philippines'** and 'resembling a hummingbird' are modifiers. they use somewhat different specific verb forms—but they both modify the same thing, and so they're parallel.

C: The comparison is cooking vs. taking: cooking spices vs. taking spices (for medicinal use). That's okay. The issue is that we can't say "taking spices is done in large quantities..."
E: that's wrong, because it's not the usage that's in small quantities; it's the spices themselves. (the sentence allows the possibility that the spices are used all the time - as long as the quantities are small.)

B：as far as "what"---
this construction is idiomatically ok: what + SUBJ + VERB is a perfectly good way to generalize the object of that particular verb.
for instance, what you eat means, basically, "the things that you eat“.

‘remainder' and 'balance' mean 'the rest of the stuff'. in other words, these words exist specifically to convey the notion of 'NOT everything'.

把thought and figures当作动词了晕

"supplier partnerships" (arrangements in which the purchaser forgoes the right to pursue alternative suppliers), which can inappropriately shelter suppliers from rigorous competitive scrutiny that might afford the purchaser economic leverage. 因为这种partnerships固有模式的存在 使得很多固定供应商免于激烈的价格竞争, 而这种竞争会给purchaser带来economic leverage.换句大白话来说：省钱

b为什么对呢？没说哪一边增长呢？
