Read the article and select the best answer. 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. Question: Which of the following people recognized the mistake first? Options: A: Karl Glazebrook B: Ivan Baldry C: Johns Hopkins D: Mark Fairchild
