Because an oversupply of computer chips has sent prices plunging, the manufacturer has announced that it will cut production by closing its factories for two days a month.
A. Because an oversupply of computer chips has sent prices plunging
B. Because of plunging prices for computer chips, which is due to an oversupply
C. Because computer chip prices have been sent plunging, which resulted from an oversupply
D. Due to plunging computer chip prices from an oversupply
E. Due to an oversupply, with the result that computer chip prices have been sent plunging
对于C和D的解释
C The violation of chronological order is confusing; reference of which is ambiguous.
D This backward description of the events behind the announcement of factory closings is confusing and awkward.
为什么说这两个的chronology是confusing呢，我知道原意的顺序是，first oversupply，then price plunging，finally closing factories
但C和D都说了from an oversupply，除去这两个选项语法上的问题不说，我觉得from oversupply就是说明了oversupply在price plunging前面呀
搞不懂，请指教~

C项的话，根据句义的话应该是computer chip prices have been sent plunging 这个整句话由oversupply引起的，但是which只能指代前面的名词而不能指代整句话，所以C项不对。
D项的话，prices from an oversupply指从过度供给中出来的价格，在这里from不能表示由什么原因引起的意思吧。

哦，大意了，C项which是修饰prices，这里就变成price resulted from oversupply了，而不是price plunging这个现象resulted from oversupply,这样理解对吗
但是D项还是不是很清楚，OG为什么说它的chronology confusing呢，我觉得先后顺序挺清楚的呀。

我知道了，D中Due to plunging computer chip prices from an oversupply的主体还是plunging prices，from an oversupply只是做它的修饰，所以整句话的意思变成plunging prices caused the manufacturer to close factories了，而原意的顺序是oversupply caused price plunging；then this fact caused closing factories.所以才说backward的表述造成了confusing。
是这样吧~
