9.    Migraine, the most debilitating common form of headache, afflicts perhaps 18 million Americans, who collectively lose 64 million workdays a year, and they cost the nation $50 billion in medical expenses and lost work time.
(A) year, and they cost the nation $50 billion in medical expenses and lost
(B) year and thus cost the nation $50 billion in medical expenses and lost
(C) year, so as to cost the nation $50 billion in medical expenses and lost
(D) year that costs the nation $50 billion in lost medical expenses and
(E) year, which thus cost the nation $50 billion in lost medical expenses and
这题答案是B，但是cost的逻辑主语应该是MIGRAINE啊，如果是这样的话B就不对了

cost是不是也是由who引导，从而与lose并列?

Energy

感觉逻辑主语不是AMERICANS啊

ssss

这道题我也有疑问，觉得主语应该是migraine。

两个主语不同的句子并列时，后面的句子怎么能省略主语呢？

一点看法：
505. migraine, the most debilitating common form of headache, afflicts perhaps 18 million americans, who collectively lose 64 million workdays a year, and they cost the nation $50 billion in medical expenses and lost work time.
(a) year, and they cost the nation $50 billion in medical expenses and lost
(b) year and thus cost the nation $50 billion in medical expenses and lost
(c) year, so as to cost the nation $50 billion in medical expenses and lost
(d) year that costs the nation $50 billion in lost medical expenses and
(e) year, which thus cost the nation $50 billion in lost medical expenses and

A：They 需指代复数名词，在此为 Americans还是workdays ?
C：so as to 似乎暗示美国人藉这种病要如何如何，不佳。
D：that 要代替谁好？单数应该指migraine，还是整句！且and的平行容易有争议的。
E：which代替谁？整句？且and的平行容易有争议的。
B：thus = with this result 副词，指明前述整句的结果。但为何不用单数costs？此句是Americans lose… and cost并列现在动词式。配上 in medical expenses and (in) lost work time 并列形容词＋名词构成的。
这里有个语意的观念不同
expenses 是 cost 掉的
time 是 lost 掉的
放错位置可是不好的！
