OG SC 33题中关于完成时态表示先后顺序的疑惑~

JasonWBW

33. 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,

题目中事情的顺序应该是: oversupply---> price plunging---->
announcement, 在题干中说道宣布的时候已经用到了现在完成时态, 那么表示发生在此之前的涨价怎么还能用同样的时态呢?正确选项A中还是用了has sent, 这样不就没有办法体现sequence了么?

大家的想法呢?

都是针对现在产生影响，应该没有问题吧?
