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.
错选E， 思路：从划线后的主语感觉保留DE，DE中确实纠结了一下，感觉划线后的rate是人的rate。 正确答案是B。 看来思路差了很多啊。 听了录音还是不是特别明白。D怎么不行呢？人的率应该对啊。可否用is排除D?

The passage suggests that for an Andean highland village attempting to resolve the problem of unequal resource distribution, the strategy known as compressed verticality would probably be inappropriate for which of the following situations?
做题的时候基本上没思路，从全文的关系首先排除了A。定位定在了 The first is "compressed verticality," in which.....manage the extraction of products unavailable in the homeland.一直到the second之前。感觉C和E和原文的那串数字9000、3000、6000有关，但觉得跑题跑得有点远，就猜了C。 老师，在做EXCEPT类似题目时，通常需要精确定位。OG上出现的EXCEPT提大多数是一连串挨着的条件。如果今后遇到EXCEPT题型时，如果没有紧挨着一连串，应该怎么办？

It can be inferred from the passage that which of the following is the reason that the author faults the journalists referred to in the highlighted text?
排除E因为觉得E的重点不是在于journalists没有考虑到GDP的XX因素（比如增长速度） 而是在于他们没有选择一个正确的历史时期去参考，即选择前24年与1873到1973年来比较是不合适的。 而在文中重点是他们没考虑到GDP增长的速度，而没有提到时间合不合适，所以觉得无关。 B讲的内容与GDP增长速度有关，所以留了。也没看出什么大问题。

Editorial in Krenlandian Newspaper:
 
Krenland's steelmakers are losing domestic sales because of lower-priced imports, in many cases because foreign governments subsidize their steel industries in ways that are banned by international treaties.  But whatever the cause, the cost is ultimately going to be jobs in Krenland's steel industry.  Therefore, it would protect not only steel companies but also industrial employment in Krenland if our government took measures to reduce cheap steel imports.
 
Which of the following, if true, most seriously weakens the editorial's argument?
这道题我根本读不懂题干，每个单词都知道但是整个题干完全不知道在讲什么。。也不知逻辑是什么 请老师讲一下 谢谢！
