你们的ron大神对本题的解析如下：

first of all, let it be said that i don't like the mathematical illiteracy of this question: what does 'many times as/more rare' mean? i dare say that's meaningless, although 'many times as/more common' would of course make sense. (as an analogy, 'twice as long' makes perfect sense, but 'twice as short' is nonsense.) i guess the people who write the math questions don't moonlight in verbal... 

yikes, i can find errors in all of the choices. i'm guessing that the oa is probably 'e', but they're all bad: 

ALL choices: 
- plural 'leopards' is not parallel to singular 'panda' 
- 'x times as/more rare than' is meaningless, per above comments 

choice a 
- the modifier that begins the sentence ostensibly refers to researchers, creating the absurd interpretation that poaching and cultivation are occurring in the researchers' habitats. 

choice b 
- the pronoun 'them' is ambiguous (leopards / researchers) 

choice c 
- 'compared to' is unidiomatic 
- 'which' is used incorrectly (the antecedent of 'which' must be a noun or noun phrase; it can't stand for the idea of the preceding clause, as it tries to here) 

choice d 
- 'them' and 'their' are both ambiguous 
- 'many more times as rare as' is just ... terrible 

choice e 
- 'their' is ambiguous 

i guess 'e' is the best of the lot, but they're all terrible. this is without a doubt the worst gmat prep question i have ever seen.

记住，代词（it, their, they）的判定优先级是很低的。Gmat里面很多时候代词的不清楚并不是根本的问题。比如本题选项E里面，其实代词their是有一点模糊的，从语法上可以指代researchers也可以指代leopards，逻辑上明显只能是leopards。千万不要一觉得代词模糊就排除。一定要用排除法，其他4个选项都有更严重的问题，比如主谓不匹配、主动被动不搭、变更句意等原则性错误。

啊哈不是啊哈哈

making them many times more rare than 在 researchers have determined后面，成了researchers的罪过了，曲解原意❌

A选项因果对象错了, 原因是“poaching and increased cultivation”,果是"researchers have determined", 逻辑上来讲,Arabian leopards数量下降才是果

与光同航

句意：由于偷猎和在它们原栖息地增加的耕种（发现句意问题，指代对象还没出现就来代词？），研究人员发现，野生阿拉伯豹数量不足100只，稀有程度是中国大熊猫数量的好几倍。
思路分析：1.发现A中代词their，指代不清，前文没有指代对象，排除AB
2.C表意有问题，不是研究人员决定什么使得豹子变稀有，是前文的偷猎和耕种的现象使得。
3.D中的being poached被偷猎，逻辑语义错误，being多余
4.E正确，两个宾语从句并列

D Researchers have determined that, because of being poached and increased cultivation in their native habitats, 【there are】 fewer than 100 Arabian leopards left in the wild, 【thus making】接前面的there are错误 them many 【more times as rare as】这个用法不好 E Researchers have determined 【that】, because of poaching and increased cultivation in their native habitats, there are fewer than 100 Arabian leopards left in the wild, 【and that】 these leopards are thus many times more rare than 两个并列的that 引导从句用法正确

判断due to 使用的对不对很简单，看它能不能被caused by 直接替代，如果可以被直接替代，那么用法就是对的，这里AB的错误不是在due to 上面

"being" isn't ALWAYS wrong. but you can never say "because of VERBing".

be careful, though; "because of -ing" can be ok IF "-ing" is a noun.
for instance, the elephant population is dying out because of poaching is fine, since "poaching" is a noun in that instance.

A选项：介词短语due to poaching and increased cultivation in their native habitats是状语，应就近修饰一个句子。本选项中其最近的句子为researchers have determined that  xxx。但在逻辑上，由于“偷猎和栖息地减少”的，应该是“野生猎豹的数量少”，而不是“调查者确定了xxx”。因此，due to poaching and increased cultivation in their native habitats应放在determine的宾语从句中，用以修饰here are fewer than 100 Arabian leopards left in the wild。另外，many times as rare as和many times more rare than在本题中均是正确的。

B选项：分词短语making them many times more rare than China's giant pandas是伴随状语或定语。但无论充当什么成分，make的逻辑主语均是有问题的（逻辑主语可能是“猎豹”或者“调查员”）。在逻辑上，让猎豹比熊猫还少的应是“偷猎和栖息地减少”。

C选项：定语从句which makes  the leopards many times more rare compared to China's giant pandas的先行词应是最近的单数名词，这造成make的逻辑主语错误同(B)。

D选项：分词短语making them many more times as rare as China's giant pandas的逻辑主语错误同(B)。

E选项：Correct. 本选项在语法和逻辑上均是正确的。

Rubia

A many times as rare as ,many times 放在as...as 前面语义不通，不能说很多倍和...一样

B many times more rare than

C many times more rare compared to， more 不与compare to搭配

D many more times as rare as, 错误同A

E many times more rare than

排除ACD后，比较BE,B逻辑主语错误，researchers have determined 做插入语，错误，making 前找不到修饰词，错误。

所以选E

原句句子结构: Researchers have determined that, because of…, …, and that…

原句逻辑语义：由于非法盗猎和在他们原生态栖息地不断增加的采摘耕种，研究人员们已经确定目前野生的阿拉伯豹子不到100只，而且这些野豹和中国的大熊猫一样珍稀。

A. due to…原因状语修饰主句，修饰对象错误。
B. there be句型太wordy，而且状语修饰(making…)修饰错误。
C. there be句型太wordy，which不能指代句子，more… compared to搭配错误。
D. making…修饰对象不清楚，容易引起歧义，many more times中more多余。
E. 正确。
