Read the excerpt from A Black Hole is NOT a Hole. For example, imagine a fluffy snowball and a harder-packed snowball of the same size. The fluffier ball is made of less stuff. Its pull is wimpier than the pull of the densely packed ball. You can feel this difference when you hold the two snowballs in your hands. Each one presses down on your hand because of the gravitational attraction it shares with Earth. The hard-packed snowball has a stronger attraction to Earth because it is made of more material. It presses more forcefully than the fluffy one. It feels heavier. What do the differences in the two snowballs help the reader understand about gravity?

A Hard objects have a stronger attraction to Earth than fluffy objects.
B Hard objects have a weaker attraction to Earth than fluffy objects.
C Heavy objects have a stronger attraction to Earth than light objects.
D Heavy objects have a weaker attraction to Earth than light objects.
