思考为什么打了麻醉的犀牛生育率会低，B说的只是犀牛而C带上了打了麻醉的犀牛

读题要仔细啊

insignificant词意理解反了

insignificant理解反了

条件2看成了2n的因子数是n的两倍。。
如果n是奇数，那么2就是一个新因子，2n因子数＝（1+1）＊原因子数。
如果n是偶数，那么2包含在原因子里，设n里面有a次方个2，2n的因子数变成（a＋1）＊原因子数，不会一直是2倍

要把这个逻辑加强就得补充 是因为这个新政 - 富人捐钱少了 - 慈善机构都不行啦。我错选 B，B 只是说富人是主要来源，但是没有说他们会捐少啊，逻辑链少一环。

不明白C错在哪了

如何明确快速的判断倒装?

grow当 变得 讲 是系动词 后面加形容词 如：grow older
当 种植或者成长 长大 讲是实义动词

(E) million as part of a deal that will make (as part of a deal修饰前面整个句子it will purchase the division for $$；that用限定定语修饰deal，避免D中the company做主语需要反身代词的情况；will make和前面的will purchase时态呼应，正确答案)
part of a deal
Ron 说是concrete

(C) million, part of a deal making (同位语的错误同B；making表示the deal is making it the largest xxx at the time when the company will purchase the division, 时态不匹配，应该都用将来时；另外说下 a part of a deal 和part of a deal都可以对；)
(D) million as a part of a deal to make (to make的主语是the company，导致the company will make it the largest xxx, 那么这里对自己的动作需要用到反身代词itself而不是it，e.g. 我们不能说I made me happy. 要说I made myself happy.)

(A) million, which is part of a deal that will make (这个错误不用多说，which只能修饰前面紧接的部分，这里是$950 million，doesn't make any sense since $$ is not a part of a deal here, the purchase is a part of the deal)
(B) million, a part of a deal that makes (同位语，ok，同位语must tag the immediately preceding noun，所以B/C错误一样，同位语错误同位$950 million；因为deal还不存在，只能用that will make而不能用makes)

additional

Western designers', artists', and crafters' imitations 加上所有格才对

in the workplace 状语，缩小了描述范围。

(adv.) I whereby saw that he was angry. 由此我看出他生气(了。
(conj.) There is no other way whereby we can cross the river.

D选项，患有哮喘的小孩被建议练习游泳，他们长大后成为运动员从而使得得哮喘的运动员的比例增加，污染了样本。脑洞太大理解不能。
C选项：运动员比非运动员患上哮喘的几率低，运动员在chlorine中暴露时间肯定要比常人长，反而没得哮喘不是很直接的削弱吗？

在别处看到的补充，请大家指正：
OG13-36题未划线处有说到although growing slowly的表达：
Along with the drop in producer prices announced yesterday, the strong retail sales figures released today seem to indicate that the economy, although growing slowly, is not nearing a recession.
Although 后面接不完整句子 逻辑主语必须一致。

不太懂啊,although不是不与but连用吗
