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.

所有的地球细菌都是从火星来的。如果是这样，那么地球就有火星的细菌而且没有死

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。

discipline强调对behavior的一种行为准则，这里面intuition只是一种思考问题的方式

① that/which作为关系代词的区别还在于，that如果前面谓语宾语较短，that可以不紧跟被修饰成分(e.g. agreement); ② not one of.... 是一个singular; ③ B/C的代词them/they 指的one of investors，应该是单数; ④A中的were是虚拟语气。

ABC是improper idiom. 正确的是 a crime for ... to hold...; ②B中的with错误地imply了伴随的含义; ③E项改变了原意，是law的影响不是passage of the law

错选C，they指代fertilizer，但是逻辑上，造成导致环境恶化的不是“化肥”，而是“人【加速使用】化肥”或者“人【替代】传统肥料为化肥”这两件事！！此外，C选项and不平行。

Split#1: and more firmly 前后应都用比较级，去掉选项A、E
Split#2: find ways to make，去掉选项C、D。“发现方法”这个事件对“让公司变大”这个方法的目的事件有直接的影响，需要用不定式短语。
