Scientists have developed a ____ paint that may help mitigate the effects of climate change.
A
Yellow
B
White
C
Pink
D
Blue
Explanation: 

Detailed explanation-1: -The ultra-white paints are considered the opposite of vantablack, which absorbs 99.9 percent of light. They reflect so much light that a surface painted with them actually ends up being cooler than the ambient temperature around them.

Detailed explanation-2: -As we’ve discussed, painting homes and commercial buildings in white is an easy and effective way to help mitigate the effects of climate change by keeping spaces cooler than if they are painted other colors.

Detailed explanation-3: -In spring last year, a team from Purdue unveiled the first ultra-white paint-a product so white that it set a Guinness World Record. The key was barium sulfate, which allowed the paint to reflect 98.1 percent of sunlight and cool surfaces by up to 19 degrees Fahrenheit compared to their surroundings.

Detailed explanation-4: -The white paint was invented by Xiulin Ruan, a Purdue University professor of mechanical engineering, and his students. It’s a project seven years in the making with the purpose of saving energy and fighting climate change, according to a press release.

Detailed explanation-5: -“Dark-colored homes absorb 70 to 90 percent of the radiant energy from the sun, which is then absorbed into the home. White-or other light, neutral colors-will reflect most of the heat away from your home, ” he said.
