Input: Consider Input: Article: Overlooking the swollen banks of the Missouri River at Omaha's riverfront landing, one scientist has an important explanation for the past three months of flooding .While many consider the flood to be man-made, a result of water released by the US. Army Corps of Engineers upriver, his theory aims to look deeper into the root of the problem. "The Missouri River is flooding," said Dr. James Hansen, Director of NASA's Goddard Institute for Space Studies, during a visit to Omaha on Tuesday."We've had floods that usually only happen once in every hundred years a couple of times on the Missouri River recently. That's one of the expected consequences of the increasing level of atmospheric carbon dioxide." Hansen, who is considered to be one of the world's leading experts on global warming , said the Missouri River is an example of how global warming is affecting the earth ."Unless you do statistics ,and you see that the frequency of these events is changing , it's not so easy to see that changes are occurring , because the climate system has large inertia ,"he said . Hansen explained, "The ocean is four kilometers deep, and the ice sheets are two or three kilometers thick , so they don't respond immediately as we begin to change the atmospheric composition .We've only experienced about half of the warming that will be caused by the gases already in the atmosphere .The full effect is going to be felt by our children and grandchildren .And if we continue to increase the amount of CO2, the effect will be even larger." Hansen drew a comparison, "If we spend more money than what we're taking in , we're leaving a debt for our children and grandchildren to deal with ."According to Hansen, the responsibility lies in effective policy making to fight against global warming .That includes a gradual reduction in carbon emissions .Hansen suggests that a rising price be placed on carbon emissions, which should be collected from the fossil fuel companies at the first sale . Without effective measures taken by the government, Hansen said the public could expect more of the recent extreme weather patterns,, including more severe droughts and floods in the decades ahead .
Answer: the army releasing water upriver

Output: Many people think the reason for the flooding of the Missouri River is _ .

Input: Consider Input: Article: We know that the earth has become warmer over the last century. The Intergovernmental Panel on Climate Change (IPCC), a group established by the World Meteorological Organization and the United Nations Environment Program, reports that the average surface temperature of the earth has increased during the twentieth century by 0.6deg _ 0.2degC.(The _ 0.2degC means that the increase might be as small as 0.4degC or as great as 0.8degC). This may seem like a small shift, but although regional and short--term temperatures do fluctuate over a wide range, global temperatures are generally quite stable. In fact, the difference between today's average global temperature and the average global temperature during the last Ice Age is only about 5 degrees C. Indeed, it's warmer today around the world than at any time during the past 1,000years, and the warmest years of the previous century have occurred within the past decade. We also know that human activities--primarily the burning of fossil fuels--have increased the greenhouse gas content of the earth's atmosphere significantly over the same period. Carbon dioxide is one of the most important greenhouse gases, which trap heat near the planet's surface. The vast majority of climate researchers agree with these overall findings. The scientific disagreements that do still exist primarily concern detailed aspects of the processes that make up these largely accepted general themes. You can think of this website as a window into the world of scientific research. In this primer, you'll find a general discussion of the physical processes underlying the earth's climate, an outline of the kinds of data that may shed light on how the climate is changing--and the role of human activity in these changes--and a description a some of the questions and uncertainties that researchers continue to explore. This primer is organized into four interconnected sections: the Atmosphere; the Hydrosphere ; the Cryosphere ; and the Biosphere .
Answer: engages in the climate and changes about the earth.

Output: We know from the text that "IPCC" _ .

Input: Consider Input: Article: Fighting racial stereotypes on US campuses often begins by putting students of different ethnic backgrounds together -- under one dormitory roof. Sam Boakye was a freshman at Ohio State University and the only black student on his floor. He was determined to get good grades -- in part to make sure his white roommate had no basis for negative racial views. "You're pushed to do better, to challenge the stereotype that black people are not that smart," he told theNew York Times. Several recent studies have found that having a roommate of a different race can reduce prejudice , diversify friendships and even promote students' academic performance. In a study by Ohio State psychology professor Russell Fazio, black freshmen who came to college with high test scores earned better grades if they had a white roommate--even if the roommate's test scores were low. Another study on student interaction by Duke University suggests that freshmen with roommates of a different race were the most likely to diversify their friendships. "Just having diversity in classrooms doesn't do anything to increase interracial friendships," said Claudia Buchman, an author of the Duke study. "But living together with a different-race roommate does lead to more interracial friendships." There are, however, some problems with such room assignments. Fazio's study found that three times as many randomly assigned interracial roommates weren't living together at the end of the semester, compared with white roommates. Interracial roommates also spent less time together, had fewer joint activities and were less involved with each other's friends than white pairs. As for Boakye, this is not the case. "A lot of white students come without much exposure to diversity, so when their first interaction with a black guy isn't bad, they will make more black friends. I think I made a good impression on my freshman roommate. I saw him this year, and he said, 'Hey dude, you're not the only black friend I have.' That felt good."
Answer: improving physical health
Output: Having a roommate of a different race can have the following benefits EXCEPT _ .
