I think E is right!

Below is the way that I am doing this qeustions, kindly please let me know your comment if you donot agree with me:

"and" here is to connect two sentences:

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.

 

 

1. when canals and eventually railroads reached into the region, there were substantial supplies of coal that was - "there were", redundant. Eliminate A
2. once canals and eventually railroads reaching into the region, there were substantial supplies of coal having been - "there were", redundant. Eliminate B
3. with canals and eventually railroads reaching into the region, there had been substantial supplies of coal  - "had been..." wrong tense. Eliminate C
4. canals and eventually railroads reached into the region, with substantial supplies of coal being - "with..." modify "canals  and eventually railroads reached...", not logical. Eliminate D
5. as canals and eventually railroads reached into the region, substantial supplies of coal were - Right! "As" here is used as conj., meaning "when".

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.

E、as canals and eventually railroads reached into the region, substantial supplies of coal were

原文是coal was exported而E是supplies were exported，supplies（供应）可以出口吗？应该不能吧，我就是这样才把E排除，选了很不像正确答案的B

Ailsa灵幽幽

我选E

在前人基础上补充一点:

我认为这题在逻辑上时间应该有对应。as相当于when 与1820's对应 不同的时间有不同的事发生。而D 感觉这些事发生的时间不如E叙述的清晰
