注意 b选项的逗号：首先，by publicly stating that 是defuse这个动作的方式状语。状语和主句之间有个逗号，是十分常见的，例如：I play basketball, in China. 因此，这个逗号加的本身没有错误。

其次，为什么要有这个逗号呢？因为和 by publicly stating 距离最近的句子是 was quite tense。如果没有逗号，那么依据就近修饰原则， 很容易被误认为是 was quite tense 的状语。有了逗号以后，因为逗号本身表示语气的停顿，所以能更清晰的被理解为是修饰 defuse 的。这是一种语言上的“优化”，并没有对错之分（没逗号选项B也是答案）。千万别把GMAT看成是一个苛求语法规则的考试，它只不过是想用不同选项的不同语法结构展示出不同的含义而已。

Split#1:both...and...固定搭配，去掉D、E
Split#2:both...and...内需要平行，去掉A、B

recover A from B

真的会有直接告诉答案这种事情。。。

Split#1: 根据Initial Modifier，比较对象平行：去掉选项A、C
Split#2: 根据X and the rest serve 平行，去掉选项B、E

互不相容事件

Split#1: 除了C选项修饰的是picture，各个选项的开头都表明是修饰 前面“Chairman painted a picture”的主句，而picture是不能suggest的，去掉选项C
Split#2: 根据句意，suggest的动作是chairmen发出的，因此不需要使用独立主格" with the suggestion"，去掉选项D、E
Split#3: Suggest的应该是that引导的一件事，而不是“bank”，而且“in the future”修饰“bank”带来歧义，去掉选项A

把6.95看成9.95 - -｜

C 选项里：wings that are shaped so smooth and perfect ，里面smooth 和 perfect 都是用来修饰shaped 而不是wings 的。副词修饰动词，smooth 可以做形容词和副词，但是perfect只做形容词，错了。应用smooth and perfectly 更合适

ome initial considerations:
- the proper idiomatic form with 'made it possible...' is FOR noun INFINITIVE.
- the sentence contains a comparison, so you should be thinking about parallelism from the outset.

choice a:
- 'make it possible ... are able to' is redundant
- i'm not sure about 'compares' as a verb in the active voice here (although i'm not confident enough to give you a straight 'no' on the issue). to me, 'is comparable to' looks better than 'compares to' (although it's possible that both are acceptable).

choice b:
- 'to have' is unclear (who HAS the cameras? the sentence leaves that issue totally unresolved)
- 'at' is unidiomatic (you capture images WITH a degree of fidelity)
- 'with' is not properly parallel (should be 'of')

choice c: CORRECT
- proper idiom: make it possible FOR noun INFINITIVE
- 'with' = proper idiom
- proper, parallel comparison: the DEGREE of fidelity is comparable to THAT (i.e., the degree of fidelity) of 35mm film

choice d:
- change of meaning: the original sentence doesn't assert that the cameras are now possible, but, rather, that existing cameras can be improved.
- improper comparison: this sentence literally compares a DEGREE of fidelity to 35mm FILM (not logically comparable / parallel items)

choice e:
- change of meaning: the original sentence doesn't assert that the cameras are now possible, but, rather, that existing cameras can be improved.
- 'that with' should be 'that of'

审题： 第二个小时是组装 【第一小时剩下的remaining】的display

A——its weight和four quarters不平行

原文没有possible的意思，原文的can是能够的意思。

A.from身后dwindling food supplies的核心词是错误的。在逻辑上，suffer from身后的内容应该是suffer的原因。本题中海床生物受灾的原因应是“食物供给的变坏”，而不是“食物供给”。

a) and d) are wrong because of the participle 'placing', which wrongly indicates that this trend is already placing more women in leadership positions.

idiom: promise to sb. promise to do sth.

老师，我觉得A选项的逻辑就不对。Manufacturers rate的是batteries，而不是watt-hour. If they rate the watt-hour higher 本身逻辑就是错误的。你觉得呢？

which/that的修饰对象排除CD, having...是一个adverb modifier不能修饰pollutant，排除AE.

round to + ... 四舍五入到....
