How does this make sports possible? ___21 A runner’s foot pushes against the ground. Usually the ground does not move. ___22 That is, it seems to push back.

Sometimes the ground is soft, for example, if it’s the muddy. ___23 The ground doesn’t resist tight away. It doesn’t push back immediately.

Then it’s harder to run. Here’s anther example: running on the beach. Which is easier---running on hard sand or running on soft sand? ___24 When you walk, you push the ground. The ground resists, and this resistance help you walk.
