Which of the following most logically completes the argument below?
The expansion of large-scale farming in Africa and Asia has destroyed much of the natural vegetation on which elephants have historically depended, forcing them to turn to cultivated land to satisfy their enormous appetites. As a result, farmers have lost millions of dollars worth of crops annually. Yet even if elephant sanctuaries were created on a widespread basis to guarantee elephants sufficient natural vegetation, the raiding would likely persist, since            
并且原味刚开始说的是大象以natural vegetation为生，现在又提供这些natural vegetation了，但是庄家还遭破坏，B选项说的是大象会糟蹋庄家即使它们不吃庄家。而D选项说的是大象喜欢吃什么，我觉得这个和原文联系不大，

According to public health officials, in 1998 Massachusetts became the first state in which more babies were born to women over the age of thirty than under it.
我选的是B，出项了than，我觉得应该是前后比较，所以than后面得加个词。这个句子整个都没看太明白，感觉B还靠点谱，就选了B。

Each of the following is mentioned in the passage as a difference between G10 garnet and other versions of garnet EXCEPT
当时选了E。 听了以前的答疑录音，知道定位的原文句是有E的意思的，可是我当时就是E没读懂appearance in conjunction的意思，和原文的意思对不上号，才选了E的。 A的oxidation在原文中出现过，但有oxidation的句子比较长，没仔细读。 时间压力下，就把E当做EXCEPT了。 请问，有没有办法在读不懂E的情况下选对呢？ 谢谢老师~

The first shots of the American Revolution, fired at Lexington and Concord.  Massachusetts, were, according to legend, heard around the world, but news of these shots, which were sent by swift messenger, took four days in reaching New York City as well as another additional eleven days to reach Charleston, South Carolina.
选的C。 上来直接把D、E排除了，觉得BC和DE分别是被动和主动的区别, 而news of shots不可能自己took four days去到达纽约。 现在知道news是不可数名词，但还是不知道E项为什么对。

Although people in France consume fatty foods at a rate comparable to the United States, their death rates from heart disease are far lower in France.
b/e两个选项，我读成这样： b：尽管人们在法国和美国消费的食物含有相同脂肪率，但是在法国因为心脏病引起的死亡率更高； e:尽管在法国和美国人们消费的食物的脂肪率相同，但是在法国因为心脏病引起的死亡率更高。 对比两个选项，在表达方式上一个是主动，一个是被动，我认为后半句是以死亡率开头，所以前面先说脂肪率更加对应。请老师指点。

When trying to identify new technologies that promise to transform the marketplace, market researchers survey the managers of those companies that are developing new technologies. Such managers have an enormous stake in succeeding, so they invariably overstate the potential of their new technologies. Surprisingly, however, market researchers typically do not survey a new technology’s potential buyers, even though it is the buyers—not the producers—who will ultimately determine a technology’s commercial success.

Which of the following, if true, best accounts for the typical survey practices among market researchers?
我留下了C，D选项。当时看完C后，意思就是说manager会对投资者造成影响，所以认为这个选项和原文沾点边。D说buyers很难被identified，感觉也沾点边。。再时间压力下，选了C，结果答案错。老师，在剩余两个选项时，如何能选出正确的呢?
