She sees a goose in her way and stops to let it pass.
C: Moving at a constant speed in the same direction as section A, but not as quickly
She continues again, but this time more slowly in case there are other animals.

There was another animal, but not a goose! She quickly turns her vehicle around to go back to the ranger station at a high speed.
