The correct option is option letter B (A serious athlete makes a total commitment to competing). The short story “Raymond's Run” by Toni Cade Bambara (1990) narrates the story of Hazel Parker (Squeaky) and how she decides to coach her brother Raymond, who has a mental disability, putting her own running career off to coach Raymond. The excerpt from this short story presented above narrates how Squeaky fully commits to her competition noticing everything, but taking care of his energy. For instance, she prefers not to holler at her brother who is alongside the track so as not to waste energy before her competition. This clearly describe how professional and serious she is about competing.
