they指代的问题。they在语法上指代的是1981的小孩，但在语义上显然是不符合逻辑的，They应该指的是1997年的小孩。
按选项翻译说：1981年小孩们平均每周花少于2个半小时的时间做家务，到了1997年他们每周花6个小时做家务。

that figure 突出了时间数值的变化，更连贯。they had spent... 这表示在某个时间段内完成了某事，这个时间段会造成混淆

they 代指 children in the United States, but by 1997 children in the united states had spent nearly six hours a week means the action of spending nearly six hours a week continues to happen before 1997. 到1997后，他们spend six hours a week的action就结束了。这显然不是语义所表达的。
正确选项应该是that figure(代指 two and a half hours a week) had grown to nearly six hours a week. 指的是直到1997，这个数字已经增加到了6个小时（implied after 1997，这个six hours 不一定继续增长，但是在1997时已经增长到了6个小时）。

grammar問題, they 是指前面的那群小孩在1997年的改變,但題目是想要表達, 社會趨勢,不是同一群小朋友)they had spent nearly six hours a week (他們在1997 年每週花6小時做什麼???) 這裡交代不清楚)

A.by 1997 they had spent nearly six hours a week they指代错误，they指children in 1981 ；实际上是children in 1981与children in 1997比较。

time tense (past perfect) is weird; it implies that they had put in 6 hours of work (total) by 1997. alternatively, it implies that they had put in 6 hrslwk at some point prior to 1997, but that they hadn't maintained that level of output.
