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.

答案是A，但是明显and两边作为原因的，前面是as a result of引导的短语，但后面是because引导的句子，这样子也可以么？？
而我一开始选择的是答案B，因为都是due to 的结构啊，这样子刚好平行啊，不懂答案怎么这样，求解！！

GWD的语法讨论索引为什么只是1-13，后面的怎么没有呢？这个是为什么啊？说14到21比较新，为什么反而没有索引讨论。。。

a: as a result of 和 because 都表原因虽然看上去不平行
b： in addition to 没有表原因的意思不平行
c：with being 错
d：前半句就一个名词结构不构成句子错
e：being 错

看来我还是把in additional 和那个to分开来看了，如果中间加一个逗号，应该这个答案就比较好了，A那个实在读起来都觉得很别扭。。。
谢谢你了！
