Step-by-step explanation:
Reading to a fifth-grade class was so risky for Kenny because he was not confident in his reading skills. He had the belief that books should only contain foreign characters and subjects that he couldn't personally relate to. However, when he discovered African books, it changed his perspective. The introduction of African books allowed him to feel more connected to the stories and made reading to the fifth-grade class a risky experience for him.
