被 E 的长句子绕晕了。/(ㄒoㄒ)/~~

Parallelism error - Between B and D. "weather conditions that cannot be foreseen" is correct over "not forseeable".
(Parallelism: can be carefully planned .... can not be forseen is present in B)

A: You cite pronoun ambiguity as the reason to eliminate answer choice A, but the GMAT has shown a surprising tolerance for pronoun ambiguity, so you shouldn't use that for elminations. Stragnely, the GMAT is almost completely intolerant of the word "being" (OG13 #100 is one of the few correct uses of the word being), so you can comfortably eliminate choices with "being".

首先，题目中结论和前提都跟生产部门没有关系，所以可以排除A和B选项；
其次，样品是most employees,总体是any employee，所以要质疑也是针对most employees，所以E不对D是答案

B 选项的翻译应该是 “没有一个城市中的公寓已经自主开展了能源节约计划” 吧？

E选项错啦！！！应该是 E--that is found in the Philippines and that, resembling。
我还想问，现在这个错的显示 “that is found in the Philippines, resembling”，是不是就可以算对了？

no less...than 是多的意思是吧？
D是因为不是在讨论discord这个过程？

as opposed to是“相反”的意思，instead of是“而不是”的意思

【A】... students boycotted classes in a one-day strike to protest a law that ...Now everything after 'that' is telling us more about that particular law.
What does the sentence tell us about the law? It tells us the following:
The law requires them to contribute $330 a year toward the cost of higher education, instead of the $7 per year required previously.
This modifies the law. A part of it cannot refer back to the students, a noun from which it is very far.

求老师指证是否正确。

A. The present participle modifier " making them..." needs a complete clause to refer to - it would then refer to the effect of the whole clause or just to the subject of the clause. However "By the same techniques used for genetically enhancing plants" is a prepositional phrase, not a clause, and therefore the present participle "making them..." cannot refer to this prepositional phrase.

连词so that必须连接两个句子。

选项B：that的位置不对。if students recognize and apply these skills, they will become more effective thinkers是two assumptions之一，因此，应该将其作为assumption的同位语从句，即，在整个句子身前加that。

A：with nearly 90,000 tons a year sold to foreign markets是独立主格。我们知道，过去分词短语表达被动语态，其表明的是“有九千多吨一年被卖到了国外的市场上”，这句话没有指明是“谁”在把这九千吨东西卖到国际市场中。

but 是连词，连接两个分句。
选项E：伴随状语placed with others of their species和其主句placed with others of their species之前不能出现副词then，只有if可以和then连接。

D. canals and eventually railroads reached into the region, with substantial supplies of coal being-" This somehow seems to imply that the canals and railroads reached into the region because of substantial supplies of coal were exported. Meaning issue"-INCORRECT.
E. as canals and eventually railroads reached into the region, substantial supplies of coal were-" 'as canals...' presents a reason as of why the substantial supplies of coal were exported."-CORRECT.

【D】comma+with phrase is absolute structure which provide the context for main clause, in this case, "coalfield open and canal reached" . D means：in the context that the export rises, coalfield opened. This is not logic.
D is typical wrong answer which is grammatical but contains meaning problem. absolute phrase modifying wrongly the main clause is the favorite of gmat. this situation happen often in og and gmatprep.

C选项 As with不是表示正如、与…一样吗？为什么要把as 和with 拆开解释？
另外，用beginning分词在这里是否正确？

老师那为什么able是 be able to do ，capable是capable of doing

A中sell是和pilfer并列吗？感觉怪怪的，像三者并列一样...
