Question

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping.

Diane made a rubber silicone mold of the impression. Then, she made a sturdy wax cast of the mold and sent it to a metalworks company. The foundry workers coated the wax mold with plaster and put it in an industrial oven. The wax melted off, leaving a plaster shell. The workers poured melted bronze into the shell, and the metal cooled and hardened into a bronze tiger tongue.

Diane’s casts of the tongue and paw allowed zoo visitors to share her amazing experience. People felt the roughness of the big cat’s tongue and spread a hand inside the palm of its giant paw. This, she decided, was one of the coolest things I have ever done. She savored the moment, knowing that far graver matters were always just a phone call away.

Which statement best describes Hopping’s viewpoint and purpose in this excerpt?

A. The author thinks that making the casts of the tiger is an amazing experience, and writes to persuade readers to make casts of their pets.

B. The author enjoys visiting the National Zoo in Washington, D.C., and writes to encourage readers to visit their local zoo.

C. The author views Diane France’s work with tigers as dangerous, and writes to warn readers to stay away from them.

D. The author finds Diane France’s experiences interesting, and writes to inform readers about the process France used to make a bronze tiger tongue.
