Whereas lines of competition are clearly defined in the more established industries, in the Internet industry they are blurred and indistinct, as companies that compete one day may be partners the next.

给出的答案是b，搜索到了讨论帖，但是年代久远不能回复。讨论是在a，b之间纠结。 这里想说的是，如果选b，后面半句as competing companies one day may be partners the next，这根本说不通！one day 干什么用啊？因此我认为选a。请各位指正，谢谢
另外再问一个 18. GWD17-Q18: Over the course of the eighteenth century, the average output of ironwork tripled as a result of several improvements in blowing machinery and because coal replaced charcoal as the fuel used in the smelting of iron ore.
A. Over the course of the eighteenth century, the average output of ironwork tripled as a result of several improvements in blowing machinery and because coal replaced charcoal as the fuel used in the smelting of iron ore. B. Over the course of the eighteenth century a tripling in the average output of ironwork was due to the replacement of charcoal by coal for the fuel used in the smelting of iron ore, in addition to several improvements in blowing machinery. C. With charcoal’s being replaced by coal as the fuel used in the smelting of iron ore and several improvements in blowing machinery, the average output of ironwork tripled over the eighteenth century. D. The replacement of charcoal with coal for the fuel used in the smelting of iron ore and several improvements in blowing machinery, the average output of ironwork tripled over the eighteenth century. E. Charcoal being replaced by coal as the fuel used in the smelting of iron ore, and several improvements in blowing machinery, which tripled the average output of ironwork over the course of the eighteenth century. 讨论中说正解是c，我手上答案是a， 目前看来a的问题在于because,c的问题在于可疑的with sth's being done结构

Stepping out of lurkdom for a moment...
"Whereas" and "although" are both correct. We can't choose between A and B on the basis of these words.
The reference of the pronoun "they" is unambiguous in both A and B. It refers both logically and grammatically to the subject of the preceding clause "lines." We can't choose between A and B on the basis of this word either.
What makes B wrong is the phrase: "as competing companies one day may be partners the next." The separation of "competing" from "one day" confuses the intended meaning. In A, "companies that compete one day may be partners the next" is clear and logical.
回到题目上来， CDE都很容易排除， AB的they指代都多多少少有问题，所以只能靠as...来排除。 A中的 as companies that compete one day may be partners the next 有问题，如下： 如果考虑成as + n.就不符合逻辑，所以要考虑成as + 句子。 那么companies that compete one day may be partners the next 就是一个句子，而这里的that compete one day就是修饰 companies 的定义从句，句子简化成 companies that... may be partners. 比较B答案中的简化形式： competing companies may be partners. (在这里，我去掉了one day 和 next day 因为他们形式功能完全对称)。 如果根据定语从句要尽可能的简化的原则，B也更简化而又不产生歧义。 我个人认为B更好 望大牛们给予认证
