I'm taking a test and have to guess the right answer to the question after the article. Article: What is the color1 of the universe? Astronomers had not answered this question, until two months ago. That is when two American astronomers reported on their study of all the light in the universe. They said that the universe would appear to the human eye to be a light greenish color1, called turquoise . Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their finding in January. They presented the research at a meeting of the American Astronomical Society. They said that finding the color1 of the universe was not part of their serious scientific research. They did it for fun. However, earlier this month, the scientists admitted to making a mistake. They said their finding was much more color1ful than it should have been. They now say the light from our universe is closer to white. It is more like a milky or creamy white color1. Their study attempted to show what people might see if they could observe the universe from far away. The scientists found the average color1 by combining light from about two-hundred-thousand star systems. Their information came from an observatory in New South Wales, Australia. These scientists and color1 engineers attempted to reproduce the result. Mark Fairchild of the Rochester Institute of Technology in New York was the first person to identify a mistake. He discovered a mistake in the computer software program used by the Johns Hopkins scientists. When the mistake was corrected, the results changed. The new color1 of the universe is much less color1ful. It is very close to white. The scientists have apologized for the mistake. They are now working with the Rochester Institute of Technology to produce more images of the color1 of the universe. They also asked for suggestions for a name for the new color1 of the universe.

I'm taking a test and have to guess the right answer to the question after the article. Article: London--coffee protects mice from radiation and could get the same way in humans, according to Indian scientists. Scientist at India's Bhabha Atomic Research Center discovered that mice injected with caffeine remained alive after high doses of normally _ radiation. Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans . "It does suggest that coffee might have some beneficial effects in protecting against radiation," he told New Scientist magazine late last month. George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation ,enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams of caffeine per kilogram of body weight were still alive. On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died. Question: Which is the best title of the article? Options: A: Human and Mice B: New Radiation Defense--Coffee C: Deadly Radiation--Gamma Radiation D: Mice Died of Caffeine
