Question

read this excerpt from \the world on turtles back.\

without knowing it, the right and left-handed twins built balance into the world. the plant-eating animals created by the right-handed twin balanced out the meat-eating animals created by the left-handed twin. and so the world thrived, and this was good.

which statement best describes the purpose of this excerpt?
to describe who created plant- and meat-eating animals
to explain that some animals are good and others are evil
to explain how balance came to exist in the natural world
to describe two different kinds of animals found in the world

Explanation:

The excerpt opens by stating the twins unknowingly built balance into the world, then uses plant-eating and meat-eating animals as an example of this balance, concluding the world thrived because of it. The other options are too narrow: the first only focuses on who created the animals, not the core purpose; the second incorrectly frames animals as good/evil, which is not stated; the fourth only describes the animal types, ignoring the balance theme.

Answer:

to explain how balance came to exist in the natural world
