Thanks so much Andrew?
We can also eliminate B and C because there is no parallelism between ‘opened’ and ‘reaching’ right? A is wrong because ‘was’ is faulty w.r.t ‘supplies’.
Can you please check if my reasoning is correct?
Posted from my mobile deviceHello again,
Krishchamp. I agree with you on (A) and (B), but (C) is a little different. My
red highlights below show errors.
A. when canals and eventually railroads reached into the region, there were substantial supplies of coal that
wasB. once canals and eventually railroads
reaching into the region, there were substantial supplies of coal
having beenC. 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 beingIn (C), it is not a problem to say,
with canals... reaching on its own, but the past perfect
had been indicates an action that occurred further in the past than another, and it would not make sense to suggest that coal had been shipped out in vast amounts prior to the construction of the canal and railroad lanes that opened up such transportation pathways.
I hope that helps. If not, you know how to grab my attention.
