Reading comprehension./ Read the passage and choose the best answer for each item.
Researchers at Stanford University have developed a new material that can move heat out ofbuildings and into space. The material can cool buildings even on hot days.The cooling material is a very thin sheet with many layers that could be placed on a roof likesolar panels. However, instead of turning sunlight into energy as solar panels do, the material turnsheat into infrared radiation.Shanhui Fan is an electrical engineering professor at Stanford University. He says that thepanels have a layer of material that is like sand. The panels also act like a mirror. They take heatout of buildinas and reflect the light from the sun. Both the heat and sunlight are sent 100kilometers into outer space.The panels are cool to the touch, even in the sun. Researchers say they can reduce the indoortemperature to nearly five degrees Celsius below the temperature outside.Mr. Fan says it is like having a window into space. He says the heat is sent directly into spacewithout warming the air. Buildinas in developing countries that do not have electricity or airconditioning could use the panels. In areas where one is off-grid, there is a significant potentialbenefit for storing medicine or even food. In many of these situations, being able to reduce thetemperature is important. And this would provide a way to do it.

Thevsay the main problem is creating actual cooling systems using the high-tech panels. lt may bepossible to develop a cooling spray technology in the next three to five years that could be used onexisting solid structures.
