avigutman,

after reading the whole thread, I am still not so sure B is incorrect.
why I thought B is candidate because,
-in the survey 25years ago ,as regard with the whole day, 24hrs , 10 hours were for 4 categories and 14 hours were for many other aspects.
-now the 8 hours are for 4 categories , and 16 hours were for others.
so it I possible the rank of housework time move up but fewer hours for housework.
please clarify ,
thanks in advance.
have a nice day
As you suggest, we
could imagine a scenario where non-surveyed activities take up a great
proportion of people's time than they did twenty-five years ago. But would this really help explain the discrepancy?
Not really. The passage says that housework has become less "demanding of time." This means that it takes less total time, not that it accounts for a smaller
proportion of the time spent on different activities. So even if the proportion of time spent on housework versus other activities went down, this wouldn't explain why house work has become less "demanding of time."
Additionally, (B) doesn't actually tell us that non-surveyed activities ended up taking more time now than twenty-five years ago, so we can't actually make that assumption. And even if we did, this wouldn't necessarily cause the amount of time spent on housework to go down. In fact, (B) doesn't tell us anything about how much
time people spent on housework.
Because it doesn't help explain the discrepancy, (B) is incorrect.
I hope that helps!
