Read the following excerpt from Mariska’s speech on the importance of adopting pets from a shelter: (1) “Marvin spent the first six months of his puppy life alone. Separated from his mother and siblings, he scavenged for food in alleys and faced constant danger from cars and wild animals. (2) When shelter rescuers found him, he was malnourished, mangy, and host to a swarm of fleas. (3) But his eyes shone with a pure puppy joy when they bathed him, fed him, and scratched his furry belly. Before long, he was ready to go to a loving home. (4) This is Marvin today. Have you ever seen a happier dog? Adopting a shelter pet gives all the world’s Marvins a brighter future.” When Mariska delivers this speech, where should she shift her facial expression? A.
