Why does the author mention the survival of “snakes, lizards, turtles, and crocodiles” in paragraph 3?

• To argue that dinosaurs may have become extinct because they were not cold-blooded animals
• To question the adequacy of the hypothesis that climatic change related to sea levels caused the extinction of the dinosaurs
• To present examples of animals that could maintain a livable body temperature more easily than dinosaurs
• To support a hypothesis that these animals were not as sensitive to climate changes in the Cretaceous period as they are today

This is a multiple choice.
