In 1981 children in the United States spent an average of slightly less than two and a half hours a week doing household chores; by 1997 they had spent nearly six hours a week.

In 1981 children spent 2.5 hours doing chores; by 1997 that figure had grown to 6 hours.

A.     chores; by 1997 they had spent nearly six hours a week （they 代chores还是children?)

B.     chores; by 1997 that figure had grown to nearly six hours a week

C.    chores, whereas nearly six hours a week were spent in 1997 （个人觉得用whereas的前后两句应该是平行的，但是这里是被动）

D.    chores, compared with a figure of nearly six hours a week in 1997 （个人觉得compared with的主语应该是主句主语children,不合逻辑）

E.  chores, that figure growing to nearly six hours a week in 1997 （如果是从句，它没有谓语，同位语的话，修饰的应该是chores,不合逻辑）

A. they不是指代不清因为spend主语必须是人 就是指代children in American 感觉应该是idiom的问题
D. compared with 可以和前面句子中的主要成分比较（prep里面有相关的总结），错在a figure of six hours a week

纠结啊！
个人认为A中they指代没任何问题，In 1981是状语，因此不是children的修饰成分，they指代children（同名异物），问题是不是因为中间是分号，后面是单独的句子，所有导致花费6小时干什么表达不清呢？
B选项 BY+过去时间点，用过去完成时好像没有问题
C最大的问题是平行结构中，主被动要统一吧，前面是主动，后面用了被动
D中个人认为compared with没有问题吧，记得prep语法笔记中有个总结compared with，除了可以与主语比较，还可以与名词成分的核心词进行比较。问题是不是出在这里比较的是hours（时间）与figure（数字），比较不对等呢？
E中的独立主格表达改变了句子重心
