Respuesta :
The golf ball represents the solar system and the football represents the Milky Way. Our solar system is a lot smaller than the Milky Way, just like how a golfball is smaller than a football.
The last choice is the only one on the list that has the objects in the right order of sizes . . . the Milky Way galaxy is bigger than the solar system.
But you have to think about this a little more, and try to understand something. (This is going to be confusing, but that's just the way it is. There's no way for a human mind to really wrap itself around the REAL distances in space.)
If the solar system shrank down to the size of a golf ball, then the Milky Way would be shrunken down to about 6.5 times the size of the real solar system ! !
The football doesn't quite get that idea across.
