In the 1820’s, anthracite coalfields opened in eastern Pennsylvania, and when canals and eventually railroads reached into the region, there were substantial supplies of coal that was exported to the nation’s growing mills, forges, factories, and railways.

A.    when canals and eventually railroads reached into the region, there were substantial supplies of coal that was
B.    once canals and eventually railroads reaching into the region, there were substantial supplies of coal having been
C.    with canals and eventually railroads reaching into the region, there had been substantial supplies of coal
D.    canals and eventually railroads reached into the region, with substantial supplies of coal being
E.    as canals and eventually railroads reached into the region, substantial supplies of coal were

答案是E，让在下想不通的是A错哪了。哪位大侠指点一下。。。

A中的there be 不好， 还有coal that was 限定修饰不太好。
as表示原因， 我偏向e。

A中，and 引导when 从句，与前面的分句并列，但是形式上不平行，不符合平行规则。there be 结构一般适合自然客观存在，用在此处亦不妥。
但是由于不知道划线部分具体为哪一部分，所以，虽然偏向于E但是，感觉怎么像是两个句子并列却缺少连词呢

我的理解是and 连接了两个句子，第二个句子包含个as的状语从句。

似乎在GMAT中there be结构不鼓励用于复杂句，there were sth that was done to..，与sth was done to相比，很awkward and wordy。

Agree
there are … that …的句型contributes nothing more than unnecessary words，详见OG12第113题

本来是觉得E更加简洁的，但是supplies可以被export吗？怎么感觉上逻辑不通呢？应该是煤被出口才对吧？

这道题我一开始也错选D，后来想通了为什么E才是对的。这两个选项要从句子的重心着手，一般来说，正确选项的表意重心和原句是一样的。原句中when canals and eventually railroads reached into the region, there were substantial supplies of coal that was exported to the nation’s growing mills, forges, factories, and railways.  用when引导的时间状语从句，来突出 there were substantial supplies of coal that was exported to the nation’s growing mills, forges, factories, and railways.这个事实。而D选项canals and eventually railroads reached into the region, with substantial supplies of coal being 使用with，和原句的表意重心正好相反了。 确保原句的意思不变是GMAT中一个很重要，也很trick的考点。

我也是这样考虑的。总觉得the supplies 是不能被exported，难道我想太多了，因为A比E错得更厉害。。
