说下我的思路，没有考虑很复杂的时间终点这些，因为做题时时间很紧，没有办法细细去品味的。
A 错在and that后面的it，it只能指名词，而不能前文的一句话。且举例子用such as比like好
C 错在explaining，现在分词两种用法，表修饰或者表结果。用火做饭和解释特点，并没有因果和修饰关系，而应该是并列关系。用like也有问题
D 同错在explaining
E 表目的用for不好，表举例子用like不好

D理解错了，是工资不上涨，不是人数不上涨

分句同个主语可以省略

原文没有possible的意思，原文的can是能够的意思。

到底是方案推理还是因果啊！！！

1) such: such需要有一个被指代的词在之前出现，主句中并没有出现group，所以没有指代，不对。（正确应该是i have no problem with using a standard geometry textbook; indeed, such a book is helpful in providing ready-made sets of practice problems.）
2）record被修饰只能用of，不能用that，这是idiom

1）A与C的contact with … directly with/through中的directly有歧义，可能修饰contact也可能修饰with/through
2）A与B的it指代不清
3）两者中只能用latter不能用last，C不对
4）due to不能表示方式，E不对。表方式只能用with/through/by means of/by way of

果因推理，他因导致

①先要整体判断逻辑关系，题干是转折关系所以不是“not only...but also”；②C选项的but前分句不完整；③E选项giving修饰created改变了原来并列的句意。

方案推理，否定副作用

比较下平行的都是名词就好了，不一定要是一个种类。或者挑一个最平行的即可。B是最平行的了。

①A项中的having amassed，having done如果看作做定语或是adverb modifier是没有歧义，是可以使用的。有歧义的不能用（Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually unregulated since they were developed more than 50 years ago.#修饰have introduced还是修饰pollutant有歧义#）
②and要判断两个分句是不是结构完整。B,C的结构不完整
③V-ing可以作状语也可以作定语，所以有歧义的可能。D,E处可能在修饰adulthood。此外，作为伴随状语，传达的是结果的意思，但是amass knowledge和drawing conclusions没有这样的必然结果的逻辑关系，D，E错误。

1）即n=5a, t=5b, 问nt即25ab的最大质因数，但a或b都可以是比5大的质因数，比如7/11等，所以无法确定nt最大质因数；
(2) n,t 只可能是3,5，7之一或二者或三者相乘，最大不超过105=3*5*7, （n或者t如果有一个超过了105， 那最小公倍数就不会是105），所以nt相乘最大的质因数就是7

same dimensions 全等

①"unqualifying" means "not meeting some sort of standard for qualification".
the intended meaning here is "unqualified", which means "without any sort of restriction or reservation".
②the present participial form "are receiving" would also make sense, but remember that you aren't supposed to change the meaning of the sentence without a good reason for doing so.

没说有没有往里存钱

If a clone loses many stems simultaneously, the resulting hormonal imbalance triggers a huge increase in new, rapidly growing shoots that can outnumber the ones destroyed.

I. ①数量的直接比较：amount X is twice as much as amount Y --> inferior, and possibly even wrong (redundant)；amount X is twice amount Y --> undoubtedly better
②表示程度等 The new house is twice [=two times] as large as our old one.
③名词在数量上的笔记（比较对象是名词不是amount）e.g.They employ 90 people, twice as many as last year.
II. AB的平行问题：B：the real problem is that "is" has no parallel in the first part of the comparison - i.e., the first part doesn't say "is emitted" or "are emitted" - and so the comparison is wrong.|A中的is being同理。
