Question: Article: If you look at the night sky, you'll often see stars moving very quickly. In fact, they move much more quickly than they should according to their size and the laws of physics. Scientists do not completely understand why the speed of these stars is so high. But many believe the reason is that much of the universe is made of something called "dark matter". Groups of stars called galaxies, such as the Milky Way, might even be made up of 90 percent dark matter. How much something weighs depends on where it is. The same object weighs only half as much on Mars as it does on Earth and almost three times as much on Jupiter. So scientists prefer to talk about the mass of something rather than how much it weighs, because mass does not change. They can work out the mass of galaxies by measuring the distance between them and the speed they move at. Recently, Jorge Penarrubia, a senior academic at Edinburgh University, UK, and his team discovered something interesting: The mass of the Milky Way is only half as much as the mass of another nearby galaxy, Andromeda. This seems strange, and dark matter may explain why. Finding out more about dark matter could help us understand how the universe began, but this is not easy. Lots of scientists with different types of expert knowledge are working on the problem. We can't see dark matter, it's very difficult to measure and we can't find out its mass. Unlike stars, dark matter doesn't produce or reflect light. But we can make a good guess that it is there because of the way things move and the way light bends. Experts now think dark matter may be very different from the matter that we find on Earth. There may also be five times as much dark matter in the universe as ordinary matter.
Answer: 7.5 kg; 45 kg

Answer: Something that weighs 15kg on Earth weighs about _ on Mars and _ on Jupiter.

Question: 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.

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

Question: Article: Cannes will rock to the sound of a cancan dance this year when Moulin Rougeby the Australian director Baz Luhrmann opens the French film festival in May. The musical stars Nicole Kidman as a singer, and John Leguizamo as the artist Henri de Toulouse-Lautrec. It will be competing for the Palme d'Or, the festival's top prize.
