?In 1981 children in the United States spent an averageof slightly less than two and a half hours a week doinghousehold chores; by 1997 they had spent nearly six hours a week.

A.chores; by 1997 they had spent nearly six hoursa week 这里的they是不对的，指代“81年的美国小孩 ”

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

C.chores, whereas nearly six hours a week werespent in 1997 这个太简略了，而且意思表达不如B

D.chores, compared with a figure of nearly six hours a week in 1997 compared with应该跟着figure

E.chores, that figure growing to nearly six hours a week in 1997 growing这里暗示grow这个动作和主句同时发生，

A. 时态错误, TWEC announced that since sales……are poor, they will…, announced与are, will时态不一致；此外，they在语法上可以指代sales，但是在逻辑上应该指代its stores，存在歧义，不正确。
B．时态错误，同A。首先，在此which只有指代了前面整句逻辑才合理，但which在GMAT里面无法指代前面整句。其次即便which能指代前面整句，which account for:说明（解释）…的原因，此处将句意变为了“关门是poor sales的原因”，所以不正确。
C．Correct；如果宾语从句引导词that不补出，依然能使正常读者清晰断句，且announce后面常常不补出。
D．announce to do是错的，正确用法是announce sth.或者announce+从句；（on account of是否可用，仍待GMAT另外说明，从未在正确句子中出现过）。
E．announce having poor sales累赘(having是一个动名词gerund)，unidiomatic；will时态错误，同A；such that用法错误。
