知道了， 应该用these/those studies来替代

为什么这个they不能指的是 studies？

a controversy concerning the significance of evidence from ALH84001：significance——究竟是否意味着暗示火星生命的存在

as可以表举例吧？GMAT中不能表举例的是like

Choice D: This choice has similar error as choice C does. In addition, this choice is more wordy since it does not use pronoun “its”. It repeats the noun – parasite’s.
Choice E: This choice has similar meaning error as in choice C. It also has pronoun number error as in Choice B.

更正1-比较结构是成对儿出现的，less +than，没有less ...compared这种说法，因此i排除ABD；
2-E和后面的题干分别是两个独立的句子，之间需要连词，nevertheless是副词，不能够链接两个句子，错误１；另外E中比较的是在不同的地点，其实发生的时间上也有比较，未体现出来，错误２；排除E；
综上，选C

我也觉得是因果推理

E) Using water would continue being restricted because not any appreciable increase in the level of the river
- "not any.." is unidiomatic and can be replaced by simple "no.."
- Also missing "had" at the end, distorting the temporal relationship between "increase in level" and "intermittent rain"

C) the use of water would continue to be restricted because not any appreciable increase in the river's level had
- use of "the use of water" leads to unnecessary passive voice
- "not any.." is unidiomatic and can be replaced by simple "no.."

B) restricting the use of water would continue because there had not been any appreciative increase in the river's level that
- "appreciative" is incorrect
- "that" seems incorrect modifier

A) restrictions on the use of water would continue because no appreciative increase in the level of the river
- "appreciative" is incorrect
- Also missing "had" at the end, distorting the temporal relationship between "increase in level" and "intermittent rain"

Analysis:
1. "appreciative" - showing gratitude VS "appreciable" - noticeable - Slight difference in word but huge difference in meaning. And "increase" can not be appreciative.
2. "Restriction" should be the main subject to convey the meaning succinctly.

maintenance和film在第一句话里的as well不已经表明了是并列关系吗？如果按照答案的理解，那不就成了film的相关动作也是maintenance的一部分了吗？

为什么没有声音呢？

D选项，即便定向广告质量没增加，只要定向投放的顾客回复率高，说明方案依旧有效。所以D是out of scope

注意方案的目标：intended to help poor farmers
argument反对的是这样做会损害发展中国家农民的利益，但发展中国家的农民比例是不是占大多数呢？多少会影响到总量？

1. grow rate can't be faster
2. growing them naturally makes no sense

PROBABLY: as fast as [they grow naturally], [..] is just a part of comparison, not a subordinate clause, so the "cutting their ..." won't modify [they grow]. That's why D is logically right on comma+ving?

析：
since与完成式连用,且时序颠倒,排除A
选项B代词she先于Bharati Mukherjee 不爽,且前一分句时序仍是颠倒,很不爽.译出来“88年入了美国籍之后,也40年出生了.时空穿越吗?排除B
选项D的第一个being纯属多余
in 1940应当用过去分词而不用现在分词完成式,since应与完成式连用,排除E
正确选项C用了Done,s v o;s v1 and v2.句子逻辑清晰,易懂.

• 'an effort to ___' vs. 'an effort that has ___'
if you're describing the goal/purpose of the 'effort'—as in this sentence—then you should use the first of these, since 'to ___' is specifically used for goals/purposes.
