OG原文解释：“A Correct. This most logically completes the argument because it addresses a potential downside of introducing the ant flies into the region. The potential downside is that it might reduce the desirable effect that other species of black ants have in keeping down the rodent populations.” 我认为说的也是CQ1: 方案的可行性。

我同意选择A，但是对评估分类有疑问。我认为是CQ1，可行性问题。
如果ant flies攻击除了loma之外的黑蚂蚁，那么black ant数量下降，原文说“black ants help control rodent populations that pose a public health risk.” black ants由于制约了rodent的数量 减少了rodent对公众健康的威胁。如果black ant数量下降，那么rodent受到制约变少，数量增多，对人类健康威胁就变大。那么这个引进ant flies就不能达到benefit的效果，所以属于CQ1方案的可行性。
恳请老师解答。

可是方案推理的话，觉得D选项并没有在谈论这个方案啊，感觉只有A选项有讲到这个方案诶……方案推理的3个CQ不是都要讲到方案才可以吗？(..•˘_˘•..)

解释里说Similar to作为比较是wordy and imprecise。这里为什么similar to 没有like好？

A novelist。。。， SL became。。。 第一反应run on首先排除了，，，

It's certainly possible all numbers to equal to 0: for example {0, 0, 0} --> answer YES.
It's also possible one number to be different from 0 and all other numbers to equal to 0 (in this case the product of ANY two numbers in the list will also be equal to 0). For example, {0, 0, 1} --> answer NO.

First 100 machines = 3% commission = 0.03*100*10000 = 30000
Commission from sale of next machines = 36000 - 30000 = 6000
So 15 more machines..

Total = 115 machines

Statement 1: if n = 40 then answer is no, if n = 60 , answer is yes.
Thus not sufficient.

Statement 2: n+6 is a multiple of 3 => n + 6 = 3m => n = 3m -6

=> n = 3( m - 2) , now if 7 = 3, its true , if m = 4 not true.

thus not sufficient.

If you combine both , n is multiple of both 3 and 5(as multiple of 20)
=> n is multiple of 15.

Thus C

x = 1/4
x^-1 = 4
x^2 = 1/16
x^(1/2) = 1/2
x^3 = 1/8.

From this, rearrange the number and the median is 1/4, which is x. Answer A

the most straightforward thing in choice B:
"gas" is singular, so "far fewer of the other gas" is nonsense. (you can't have "fewer" unless you can count things, and you can't count things unless they're plural.)

这个题是不是可以看做样本枚举？E说明了样本不具有代表性

考试的时候图经常加载不出来 只能蒙一个上去，希望老师们关注一下这个问题～

A=D 倒装还原后是彗星和彗星回来时比
Halley's comet cause such a worldwide sensation In no other historical sighting as its return in 1910–1911 did.
B 同A，had代替did后发现前面也没有done结构
E 名词结构
C 还原倒装后
Halley's comet cause such a worldwide sensation In no other historical sighting as(Halley's comet did)in its return of 1910–1911

A 正确 Heating-oil prices are expected to be higher this year than （Heating-oil prices were expected to be）last because refiners are paying about $5 a barrel more for crude oil than they were(paying) last year.
B rise higher重复 比较级用than不用over
C Expectations( for heating-oil prices) are to be higher this year than last year

reduced India's rice production
跟主句宾语做比较，所以不需要将主句动词还原

A She和photographer Lotte Jacobi 没有连词
B being错误 had emigrated 错误
D after emigrating to New York when (she was)compared to her native Germany 不应该省略she was
E 没有连词同A

错选了A
注意the number of East German residents killed each year （as car occupants）说明死亡上升的数字都是拥有者贡献的，跟passenger就无关了

选项d意思是1989年以前那些不怎么开车的人也被算在增加的范围内，所以比例的分母变大了，所以比例就变小了，是这意思吗？这题绕不明白
