再问GWD17-Q18，前人有讨论，但无解答

From www.nytimes.com

As a result of this financial arrangment and because he headed the program from its establishment in 1986, Dr. Mann had enjoyed more autonomy than the heads of other W.H.O. programs

Strategic ButtonsBut this ''import-led'' growth strategy failed as a result of the world recession and because the Soviet bloc had difficulty making efficient use of the Western technology.

 Originally, the idea was that the self-understanding that arose as a result of psychoanalysis was unique and impressive and valid because it afforded relief from symptoms that were otherwise impossible to treat.

From: www.google.com 

The inability to sell your shares in a rapidly declining market may substantially increase your risk of loss as a result of such illiquidity and because the price for our common stock may suffer greater declines due to its price volatility.

有关此题的讨论，在语法区里搜到了3处。另一处比较值得关注的帖子：

我倾向选A.

我排除C的依据是with ＋being 用法错误。

自己对with 的用法一直很模糊，在此，想请教大家能否帮忙给出完整有关with用法的小结。

拜谢先……

A我的确觉得很不爽，我当初也是选C，不过我也不是很确定

我感觉C有以下缺点

1、with sth being done非常无敌wordy。

2、也是关键的，with sth doing确实有表原因的意思。不过他后面有个并列

   With charcoal’s being replaced by coal......and several improvements in blowing machinery

也就是一个with sth being replaced and sth的结构。improvements也是原因之一，但with sth是否仍然能够表达原因，我有点怀疑

3、and的连接，improvements与什么平行并列是个问题，与iron并列还是fuel并列？（个人觉得整个理由有点牵强，不过以前有类似的题，估计不是这题重点）

只能说其他选项的错误过于严重，完全盖过了A中and前后不平行的问题。

A的and前后概念上是很平行的，也符合逻辑。。。

只能这么理解了。。。优先级啊优先级
