Which statement best explains how the plot of the story helps develop the character of Carlos?
The bus skidded to a slow stop on the icy road. The wheels spun. The
class of fifth-graders, who had just returned from a science fair,
groaned. "I'm not sure how to fix this," said Mr. Ronaldson, the bus
driver. "We might need walk to the next town."
Suddenly, a small voice spoke up from the back of the bus.
"It's easy."
Twenty-nine heads swiveled around to discover that the voice was
coming from Carlos, a new student who had just moved to the United
States that year. He hadn't spoken any English before he had moved to
town.
"There's ice under the wheels," Carlos said. "We can use your keys to
break up the ice. Then we can put cardboard from our science projects
in front of the wheels. They will be able to get back onto the road."
