请教关于SENTENSE FRAGMENT - ChaseDream

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

最近做GWD 老是在SENTENSE FRAGMENT这个问题上栽筋斗。想请各位跟我详细讲一下这种结构到底怎么判断，怎么错了？
是不是跟以前看到的那种叫“夹心饼干”的错误一个意思。
如

GWD-8-Q18:

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

答案是C我就选了D,因为我觉得，只有 ",accounting for"这样才能代表是指代了前面整个句子。因为我牢牢记住，“，which”只能指代前面的一个词而要想指代前面的一个句子的整个的意思如OG那个小鸟飞了出去就成长了的那一题目。是用-ING指代前面的意思，还有OG那个古代人的盾牌是用来PROTECTING。
那些都让我误选了D 每次都看到总结说错是错在D是sentence fragmented 。真心求教！！！！！谢谢！！！！！

According to a recent study of consumer spending on
prescription medications, increases(主语) in the sales of the 50 drugs (定从可忽略不看)[that were
advertised most heavily] accounts(谓语) 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.

而D 只有accounting 分词形式, 并不能做谓语, 后面也没有出现谓语

而正确答案C,其实用的是独立结构, 而且用名词the increase 而非which , 来修饰remainder, 避免了which 的指代歧义, 用新东方的话讲就是出现名词来代替代词是正确标志

我觉得你最好还是多做一些题目, 仔细看讨论或者OG的解释, 通过题目来体会语法现象, 而不是倒过来问语法现象是什么, 然后再做题目

-ING形式是在修饰前面整个一句话大概指的是分词表示前面一句话动作的影响

夹心饼干是说一个分词, 在其前后都有动词, 则此时分词的指代会产生歧义.
