Question

what does the metaphor in this text suggest?
he reads incessantly; new ideas are food for his mind.

he is never satisfied with what he reads.

Explanation:

The metaphor compares new ideas to food, which is essential for nourishing and energizing the body. Similarly, new ideas nourish and stimulate his mind. The other option about never being satisfied is not supported by the metaphor of food as nourishment/stimulation.

He is stimulated by new ideas.
