Read this excerpt from A Black Hole is NOT a Hole. Now try this tasty thought experiment. Say some friends far outside the black hole decide to send you a snack. If they launch a red apple your way, it’s invisible to you at first. But keep your eyes peeled! Eventually, the apple shifts from invisible to blue, then to green, yellow, orange, and finally red, as it passes through gravitational zones that are closer and closer to the same strength as yours.

Which type of graphical representation would best support a reader’s understanding of this excerpt?

someone watching an apple hurl through space
a picnic basket being launched into space
an apple made up of all the colors mentioned
a series of apples in each color mentioned
