721. According to a recent study of consumer spending on prescription medications, increases in the sales of the
50 drugs that were advertised most heavily accounts for almost half of the $20.8 billion increase in drug
spending last year, the remainder of which came from sales of the 9,850 prescription medicines that companies did not advertise or advertised very little.
(A) heavily accounts for almost half of the $20.8 billion increase in drug spending last year, the remainder of which came
(B) heavily were what accounted for almost half of the $20.8 billion increase in drug spending last year; the remainder of the increase coming
(C) heavily accounted for almost half of the $20.8 billion increase in drug spending last year, the remainder of the increase coming
(D) heavily, accounting for almost half of the $20.8 billion increase in drug spending last year, while the remainder of the increase came
(E) heavily, which accounted for almost half of the $20.8 billion increase in drug spending last year, with the remainder of it coming

正确答案C
这题从account做谓语，the remainder of XX 应该指代明确选increase可以选出C。
但是最后一个逗号后面的成分，一个长句用了coming，总觉得太奇怪了。
不知道大家如何理解的，谢谢~~~

贰乙〇

后面那是独立主格 NOUN+Ving/Ved

谁能帮我解释一下C选项中heavily修饰歧义会修饰account啊！
就是因为这个点才选了B，但是也纠结B的分号后面的句子是一整句话才可以！
