They would die within hours. They would become endangered. They would need to migrate. They would grow at a slower rate.
I gave my students this multiple choice question: Some plants rely on hummingbirds for pollination. If a deadly disease infected the hummingbird population, what would most likely happen to the plants?

Only one answer is correct among these 4 choices:
- They would die within hours.
- They would become endangered.
- They would need to migrate.
- They would grow at a slower rate.

Could you tell me which one is correct?

They would become endangered.
