Question 2
Imagine that we put a raisin cake into the oven, with each raisin separated from the others by 1 cm. An hour later, we take it out and the distances between raisins are 3 cm.
If you lived in one of the raisins and watched the other raisins as the cake expanded, which of the following would you conclude?
A) More distant raisins would be moving away from you more slowly.
B) All raisins would be moving away from you at the same speed.
C) More distant raisins would be moving away from you faster.
D) It depends: If you lived in a raisin near the left side of the cake, you'd see other raisins moving away from you, but they'd be coming toward you if you lived in a raisin near the right side of the cake.
