George is at a water park with his family. he needs to get a tube to use for one of the rides, and he chose his color first. there are black tubes, dark purple tubes, dark blue tubes, and yellow tubes. each member of his family had to choose a different colored tube. george chose a yellow tube, because he thought it would be the coolest. after everyone chose a tube, he touched all of the tubes. the yellow tube was the coolest. how do you think george knew that the yellow tube would be the coolest?
a) he knew that dark colors absorb energy, so they would be coolest.
b) he knew that dark colors reflect energy, so they would be coolest.
c) he knew that light colors absorb energy, so they would be coolest.
d) he knew that light colors reflect energy, so they would be coolest.
