Read the paragraph from a story that Andrea is writing about a girl name Marlo and her rescue dog.

Marlo and her father walked down the hallway, lined on each side by individual cages. Some cages held two or three little dogs; others held one bigger dog. How would she ever choose? In the last cage on the row, she saw a large, plain-looking black dog sitting up straight at attention.

Which addition should Andrea make to the paragraph to most clearly describe Marlo’s reaction when she finds the dog she will rescue?

A) Most of the other dogs at the shelter barked or whined when people walked by, but this dog sat quietly and calmly.

B) The sign on the dog’s cage read that he had been left at the shelter by his owners because they were too busy to care for him.

C) Marlo noticed the dog’s fur was somewhat long and course. He had a small white patch of fur on his chest that looked like a star.

D) Marlo looked into the dog’s black, sparkling eyes and felt a wave of happiness and connection. She knew this was the one.
