Article: Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. "It's a _ ," said lead researcher Frank Stafford at University of Michigan's Institute for Social Research. "Men usually work more outside the home, while women take on more of the housework." He points out that differences among households exist. But in general, marriage means more housework for women and less for men. "And the situation gets worse for women when they have children." Stafford said. Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005. Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most - about 21 hours a week. Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men. Having children increases housework even further. With more than three, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands' 10 hours.

question:
Article: Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15, 000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted to the cold, dry climates of the ice ages, but until now, no one has reached a satisfying answer. Rainforests like the Amazon are important for _ CO2from the atmosphere and helping to slow global warming. Currently the trees in the Amazon take in around 500 million tons of CO2each year: equal to the total amount of CO2giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier, will it still survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past. Unfortunately, getting into the Amazon rainforest and collecting information are very difficult. To study past climate, scientists need to look at fossilized pollen, kept in lake muds. Going back to the last ice age means drilling deep down into lake sediments which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aero-planes. Rivers tend to the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled . So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.
Answer: There is no exact answer up to present.
answer:
How will the Amazon rainforest react to future climate change?
