Question

Read the passage. Then, answer the question that follows.

Answer 1

A modern dentist would certainly enjoy having a hadrosaur as a client. Although an adult human being has only 32 teeth, these duck-billed dinosaurs of the Late Cretaceous Period had up to 2,000 teeth, with 500 along each side of each jaw. Unlike human beings, who grow two sets of teeth in their lifetimes, the hadrosaurs, like sharks and modern reptiles, had built-in replacement teeth. If a tooth became worn down or broke off, a new one would take its place. In skeletal remains of the jaws of these toothy beasts, scientists have found entire banks of replacement teeth. Like athletes sitting on the bench, they were ready and waiting to be put to use.

The teeth of hadrosaurs were similar to those of modern sharks.

The hadrosaurs teeth were evenly divided, 500 on each side.

If a hadrosaur broke a tooth, a new one would grow in to replace it.
